Chapter 1 - System Description BreezeACCESSS VL System Manual 1-2 Introducing BreezeACCESS VL BreezeACCESS VL is a high capacity, IP services oriented Broadband Wireless Access system. The system employs wireless packet switched data technology to support high-speed IP services including fast Internet and Virtual Private Networks. BreezeACCESS users are provided with a network connection that is always on, supporting immediate access to the Internet and other IP services at high data rates. The system is designed for cellular-like deployment, enabling the system architecture to vary in size and structure. A system can include any number of cells, each containing several Access Units for better coverage of densely populated areas. The system supports Virtual LANs based on IEEE 802.1Q, enabling secure operation and Virtual Private Network (VPN) services and enabling tele-workers or remote offices to conveniently access their enterprise network. The system supports layer-2 traffic prioritization based on IEEE 802.1p and layer-3 traffic prioritization based on IP ToS (RFC791). BreezeACCESS VL products operate in unlicensed frequency bands in Time Division Duplex (TDD) mode, using Orthogonal Frequency Division Multiplexing (OFDM) modulation with Forward Error Correction (FEC) coding. Using the enhanced multi-path resistance capabilities of OFDM modem technology, BreezeACCESS VL enables operation in near and non-line-of-sight (NLOS) environments. These qualities enable service providers to reach a previously inaccessible and broader segment of the subscriber population. BreezeACCESS VL is designed to enable construction of “mixed” cells, where it can be used together with other BreezeACCESS products using GFSK modulation, including BreezeACCESS II, BreezeACCESS MMDS, BreezeACCESS XL and BreezeACCESS V. BreezeACCESS VL products are currently available in the following frequency bands:

The actual operating frequencies used by the system can be configured according to applicable radio regulations and specific deployment considerations. A BreezeACCESS VL system is comprised of the following: ! Customer Premise Equipment (CPE): BreezeACCESS VL Subscriber Units. ! Base Station Equipment (BS): BreezeACCESS VL Access Units and supporting equipment. ! Networking Equipment: Standard Switches/Routers supporting connections to the backbone and/or Internet. ! Management Systems: SNMP-based Management, Billing and Customer Care, and other Operation Support Systems.
Chapter 1 - System Description BreezeACCESSS VL System Manual 1-4 Subscriber Unit The Subscriber Unit (SU) installed at the customer premises enables the customer data connection to the Access Unit. The Subscriber Unit provides an efficient platform for high speed Internet and Intranet services. The use of packet switching technology provides the user with a connection to the network that is always on, enabling immediate access to services. The Subscriber Unit is comprised of a desktop or wall-mountable Universal Indoor Unit (IDU) and an outdoor unit that contains the processing and radio modules. Several ODU types are available to supports a wide range of requirements, as detailed in Table 1-2: Table 1-2: Subscriber Unit ODU Types SU Type Antenna Description SU-A-ODU Vertically polarized high-gain flat antenna integrated on the front panel SU-A-H-ODU Horizontally polarized high-gain flat antenna Integrated on the front panel SU-E-ODU A connection to an external antenna For each ODU type, several models are available to support various end-users needs and applications, as detailed in Table 1-3: Table 1-3: Subscriber Unit Types SU Type Description SU-54-BD Supports a full LAN and a CPE gross rate of up to 54 Mbps SU-6-1D Supports a single Ethernet device (one MAC address) and a CPE gross rate of up to 6 Mbps SU-6-BD Supports a full LAN and a CPE gross rate of up to 6 Mbps SU-3-1D Supports a single Ethernet device (one MAC address) and a CPE gross rate of up to 3 Mbps
Subscriber Unit Manual Revision 1.0 1-5 The IDU provides the interface to the user’s equipment and is powered from the 110/220 VAC mains. The customer's data equipment is connected via a standard IEEE 802.3 Ethernet 10/100BaseT (RJ 45) interface. The indoor unit is connected to the outdoor unit via a Category 5 Ethernet cable. This cable carries Ethernet traffic between the indoor and the outdoor units, and also transfers power (54 VDC) and control from the indoor unit to the outdoor unit.
Chapter 1 - System Description BreezeACCESSS VL System Manual 1-6 Base Station Equipment The Access Units, installed at the Base Station site, provide all the functionality necessary to communicate with the Subscriber Units and to connect to the backbone of the Service Provider. There are 2 lines of Access Units with different architectures ! Modular Base Station Equipment ! Standalone “Micro-Cell” Access Unit Modular Base Station Equipment The Base Station Equipment is based on the BS-SH-VL 3U chassis, which is suitable for installation in 19-inch racks. The chassis contains one or two Power Supply modules and has 8 slots that can accommodate BS-AU-VL Network Interface modules. These slots can also accommodate various combinations of other modules, including Network Interface (BS-AU) modules for Access Units operating in any of the bands supported by BreezeACCESS equipment using GFSK modulation, including BreezeACCESS II, BreezeACCESS MMDS, BreezeACCESS XL and BreezeACCESS V. It can also accommodate a BS-GU GPS and Alarms module to support GPS-based synchronization of BreezeACCESS systems using Frequency Hopping radios. Two different types of power supply modules are available for the BreezeACCESS VL modules: The BS-PS-DC-VL that is powered from a -48 VDC power source, and the BS-PS-AC-VL, powered from the 110/220 VAC mains. The optional use of two power supply modules ensures fail-safe operation through power supply redundancy. When the same chassis is used also for Access Unit modules belonging to other BreezeACCESS families using GFSK modulation, then one BS-PS-VL power supply (AC or DC) should be used to provide power to the BreezeACCESS VL Access Units, and a different power supply module, suitable for GFSK equipment, is required for powering the BreezeACCESS GFSK Access Units. Each BS-AU module, together with its outdoor AU-D/E-BS-ODU radio unit and an antenna comprise an AU-D/E-BS Access Unit that serves a single sector. The AU-D/E-BS-ODU outdoor unit contains the processing and radio modules and connects to an external antenna using a short RF cable. E model units are supplied without an antenna.

The indoor module is connected to the outdoor unit via a Category 5 Ethernet cable. This cable carries Ethernet traffic between the indoor module and the outdoor unit, and also transfers power (54 VDC) and control from the indoor module to the outdoor unit.
Chapter 1 - System Description BreezeACCESSS VL System Manual 1-8 Standalone “Micro-cell” Access Unit The standalone AU-D/E-SA Access Unit is very similar to the AU-D/E-BS unit. The AU-D/E-SA-ODU outdoor unit is very similar to the AU-D/E-BS-ODU outdoor unit (identical functionality, but the units are not interchangeable). The available antennas for D model units are the same as those of the AU-D-BS Access Unit. The main difference is in the structure of the indoor part; in the AU-D/E-SA Access Unit the indoor unit is a standalone desktop or wall-mountable unit (the same Universal IDU that is also used in the SU) rather than a 19” module. The IDU connects to the network through a standard IEEE 802.3 Ethernet 10/100BaseT (RJ 45) interfaces and is powered from the 110/220 VAC mains. The indoor unit is connected to the outdoor unit via a Category 5 Ethernet cable. This cable carries Ethernet traffic between the indoor and the outdoor units, and also transfers power (54 VDC) and control from the indoor unit to the outdoor unit. NOTE The AU-D/E-SA-ODU and the AU-D/E-BS-ODU are not interchangeable: The AU-D/E-SA-ODU cannot be used with the BS-AU; the AU-D/E-BS-ODU cannot be used with the Universal IDU.
Networking Equipment Manual Revision 1.0 1-9 Networking Equipment The Base Station equipment is connected to the backbone through standard data communication and telecommunication equipment. The 10/100BaseT ports of the AU modules can be connected directly to a multi-port router or to an Ethernet switch connected to a router. The point-to-point link from the Base Station to the backbone can be either wired or wireless. Data to the Internet is routed to the backbone through standard routers.
Chapter 1 - System Description BreezeACCESSS VL System Manual 1-10 Management Systems The end-to-end IP-based architecture of the system enables full management of all components, from any point in the system. BreezeACCESS VL components can be managed using standard management tools through SNMP agents that implement standard and proprietary MIBs for remote setting of operational modes and parameters. The same SNMP management tools can also be used to manage other system components including switches, routers and transmission equipment. Security features incorporated in BreezeACCESS VL units restrict access for management purposes to specific IP addresses and/or directions, which means from the Ethernet and/or wireless link. In addition, the Ethernet WAN can be used to connect to other Operation Support Systems including servers, Customer Care systems and AAA (Authentication, Authorization and Admission) tools. BreezeCONFIG The BreezeCONFIG for BreezeACCESS VL utility is an SNMP-based application designed to manage BreezeACCESS VL system components and upgrade unit software versions. The system administrator can use the BreezeCONFIG utility to control a large number of units from a single location.

Aligning the Subscriber Unit Antenna Manual Revision 1.0 3-5 Aligning the Subscriber Unit Antenna The SNR bar display is located on the bottom panel of the outdoor unit. The ten LEDs are used for indicating the quality of the received signal. The higher the number of green LEDs indicating On, the higher the quality of the received signal. This section describes how to align the Subscriber Unit antenna using the SNR bar display. NOTE Antenna alignment using the SNR bar display is possible only after the Subscriber Unit is associated with an Access Unit. The associated Access Unit must be operational and the basic Subscriber Unit parameters must be correctly configured. If not, the unit will not be able to synchronize with the Access Unit. As the SNR measurement is performed on received frames, its results are meaningless unless the Subscriber Unit is associated with an Access Unit. 1. Align the antenna by pointing it in the general direction of the Base Station. 2. Verify that the power indication of the unit is On. 3. Verify that the W-LINK LED of the ODU is On, indicating that the unit is associated with an Access Unit. If the W-LINK LED is Off, check that the ESSID and Frequency parameters are correctly configured. If the SU is still not associated with the AU, increase the transmit power level to its maximum value. If the unit is still not associated with the AU, improve the quality of the link by changing the direction of the antenna or by placing the antenna at a higher or alternate location. 4. Rotate the antenna until the maximum SNR reading is achieved, where at least 1 green LED is on: If you encounter prolonged difficulty in illuminating the minimum required number of green LEDs, try to improve the reception quality by placing the antenna at a higher point or in an alternate location. 5. Ensure that the front of the antenna is always facing the Base Station. However, in certain conditions, such as when the line of site to the Base Station is hampered, better reception may be achieved using a reflected signal. In this case, the antenna is not always directed toward the Base Station. To align the Subscriber Unit antenna:
Chapter 3 - Commissioning BreezeACCESSS VL System Manual 3-6 6. Secure the unit firmly to the pole. NOTE In some cases, the antenna may need to be tilted to ensure that the level at which the SU receives transmissions from the AU (and vice versa) is not too high. As a rule of thumb, if the SU is located at a distance of less than 300 meters from the AU, it is recommended to up-tilt the antenna by approximately 10° to 15°. To guarantee a safety margin from the saturation level (received signal of -40dBm at the antenna port), the SNR should not be higher than 50dB. The orange LED of the SNR bar indicates that the SNR is higher than 50dB.
Configuring the Subscriber Unit’s Maximum Modulation Level Manual Revision 1.0 3-7 Configuring the Subscriber Unit’s Maximum Modulation Level This section describes how to configure the maximum modulation level for BreezeACCESS VL Subscriber Units. NOTE If the unit is associated with the AU, then the final configuration of the Maximum Modulation Level parameter may be performed remotely, for example, from the site of the AU or from another site. 1. If the SNR of the SU at the AU is too low, it is recommended that you configure the Maximum Modulation Level parameter to a value that is lower than the maximum supported by the unit. This can decrease the number of retransmissions due to attempts to transmit at modulation levels that are too high for the actual quality of the link. 2. Check the SNR of the SU at the AU. You can use Telnet to view the SNR values in the MAC Address Database, which can be accessed from the Site Survey menu. If the ATPC algorithm is not enabled in both AU and SU, the test should be done with the Initial Power Level at the SU configured to its maximum value. If the SNR is lower than the values required for the maximum modulation level according to Table 3-2, it is recommended that you decrease the value of the Maximum Modulation Level. NOTE The SNR measurement at the AU is accurate only when receiving transmissions from the applicable SU. If necessary, use the Ping Test utility in the Site Survey menu to verify data transmission. 3. Configure the Maximum Modulation Level according to Table 3-2, using the typical SNR values. It is recommended that a 2 dB margin be added to compensate for possible measurement inaccuracy or variance in the quality of the link. To configure the Maximum Modulation Level:

Menus and Parameters Manual Revision 1.0 4-27 Site Survey Menu The Site Survey menu displays the results of various tests and counters for verifying the quality of the wireless link. These tests can be used to help determine where to position the units for optimal coverage, antenna alignment and troubleshooting. The counters can serve for evaluating performance and identify potential problems. In the AU, there is also an extensive database for all SUs served by it. The Site Survey menu includes the following options: ! Traffic Statistics ! Ping Test ! Continuous Link Quality display (SU only) ! MAC Address Database ! Per Modulation Level Counters Traffic Statistics The traffic statistics are used to monitor, interpret and analyze the performance of the wired and wireless links. The counters display statistics relating to wireless link and Ethernet frames. The Traffic Statistics menu includes the following options: ! Display Counters: Select this option to display the current value of the Ethernet and wireless link (WLAN) counters. ! Reset Counters: Select this option to reset the counters. Ethernet Counters The unit receives Ethernet frames from its Ethernet port and forwards the frames to its internal bridge, which determines whether each frame should be transmitted to the wireless media. Frames discarded by the unit's hardware filter are not counted by the Ethernet counters. The maximum length of a regular IEEE 802.1 Ethernet frame that can be accepted from the Ethernet port is 1518 bytes. For tagged IEEE 802.1Q frames the maximum size is 1522 bytes. The unit transmits valid data frames received from the wireless media to the Ethernet port, as well as internally generated frames, such as responses to management queries and pings received via the Ethernet port. The Ethernet Counters include the following statistics:
Chapter 4 - Operation and Administration BreezeACCESSS VL System Manual 4-28 ! Total received frames via Ethernet: The total number of frames received from the Ethernet port. This counter includes both invalid frames (with errors) and valid frames (without errors). ! Transmitted wireless to Ethernet: The number of frames transmitted by the unit to the Ethernet port. These are generally frames received from the wireless side, but also include frames generated by the unit itself. WLAN Counters The unit submits data frames received from the Ethernet port to the internal bridge, as well as self generated control and wireless management frames. After a unicast data frame is transmitted, the unit waits for an acknowledgement (ACK) message from the receiving unit. Some control and wireless management frames, as well as broadcast and multicast frames sent to more than one unit, are not acknowledged. If an ACK is not received after a predefined time, which is determined by the Maximum Cell distance parameter, the unit retransmits the frame until an ACK is received. If an ACK is not received before the number of retransmissions has reached a maximum predefined number, which is determined by the Number of HW Retries and Number of SW Retries parameters, the frame is dropped. The Wireless Link Counters include the following statistics: ! Total transmitted frames to wireless: The number of frames transmitted to the wireless media. The total includes one count for each successfully transmitted unicast frame (excluding retransmissions), and the number of transmitted multicast and broadcast frames, including control and wireless management frames. In the AU, there are also separate counters for the following: # Beacons (AU only) # Management and Other Data frames, including successfully transmitted unicast frames and multicast/broadcast data frames (excluding retransmissions, excluding Beacons in AU) ! Total Transmitted Unicasts (AU only): The number of unicast frames successfully transmitted to the wireless media, excluding retransmissions. This count is useful for calculating the rates of retransmissions or dropped frames, since only unicast frames are retransmitted if not acknowledged.
Menus and Parameters Manual Revision 1.0 4-29 ! Total submitted frames (bridge): The total number of data frames submitted to the internal bridge for transmission to the wireless media. The count does not include control and wireless management frames, or retransmissions. There are also separate counts for each priority queue to which the frames were routed, which are High, Mid and Low (currently the High queue is not used for data frames). ! Frames dropped (too many retries): The number of dropped frames, which are the frames unsuccessfully retransmitted until the maximum permitted number of retransmissions without being acknowledged. This count includes dropped data frames as well as dropped control and wireless management frames. ! Total retransmitted frames: The total number of retransmissions, including all unsuccessful transmissions and retransmissions. ! Total Tx events: The total number of transmit events. Typically, transmission events include cases where transmission of a frame was delayed or was aborted before completion. The following additional counters are displayed to indicate the reason for and the nature of the event: # Dropped: The number of dropped frames, which are the frames unsuccessfully retransmitted until the maximum permitted number of retransmissions without being acknowledged. # Delayed: The number of frames whose transmission was delayed because they were in the queue for transmission when the SW Retry mechanism was activated for a previous frame designated to the same address. (refer to Adaptive Modulation Algorithm on page 4-81 for more information) # Underrun: The number of times that transmission of a frame was aborted because the rate of submitting frames for transmission exceeds the available transmission capability. # Others: The number of frames whose transmission was not completed or delayed due to a problem other than those represented by the other counters. ! Total received frames from wireless: The total number of frames received from the wireless media. The count includes data frames as well as control and wireless management frames. The count does not include bad frames and duplicate frames. For a description of these frames, refer to Bad frames received and Duplicate frames discarded below.
Chapter 4 - Operation and Administration BreezeACCESSS VL System Manual 4-30 ! Total received data frames: The total number of data data frames received from the wireless media, including duplicate frames. Refer to Duplicate frames discarded below. ! Total Rx events: The total number of frames that were not received properly. The following additional counters are displayed to indicate the reason for the failure: # Phy: Applicable only when DFS is enabled. The number of unidentified signals. # CRC: The number of frames received from the wireless media containing CRC errors. # Overrun: The number of frames that were discarded because the receive rate exceeded the processing capability or the capacity of the Ethernet port. # Decrypt: The number of frames that were not received properly due to a problem in the data decryption mechanism. ! Bad fragments received: The number of fragments received from the wireless media containing CRC errors. ! Duplicate frames discarded: The number of data frames discarded because multiple copies were received. If an acknowledgement message is not received by the originating unit, the same data frame can be received more than once. Although duplicate frames are included in all counters that include data frames, only the first copy is forwarded to the Ethernet port. ! Internally discarded MIR\CIR: The number of data frames received from the Ethernet port that were discarded by the MIR/CIR mechanism to avoid exceeding the maximum permitted information rate. Ping Test The Ping Test submenu is used to control pinging from the unit and includes the following options: ! Destination IP Address: The destination IP address of the device being pinged.

DHCP Client The DHCP Client submenu includes parameters that define the method of IP parameters acquisition. The DHCP Client submenu includes the following options: ! DHCP Option ! Access to DHCP DHCP Option The DHCP Option displays the current status of the DHCP support, and allows selecting a new operation mode. Select from the following options:
Menus and Parameters Manual Revision 1.0 4-39 ! Select Disable to configure the IP parameters manually. If this option is selected, configure the static IP parameters as described above. ! Select DHCP Only to cause the unit to search for and acquire its IP parameters, including the IP address, subnet mask and default gateway, from a DHCP (Dynamic Host Configuration Protocol) server only. If this option is selected, you must select the port(s) through which the unit searches for and communicates with the DHCP server, as described in the following parameter, Access to DHCP. You do not have to configure static IP parameters for the unit. DHCP messages are handled by the units as management frames. ! Select Automatic to cause the unit to search for a DHCP server and acquire its IP parameters from the server. If a DCHP server is not located within approximately 40 seconds, the currently configured parameters are used. If this option is selected, you must configure the static IP parameters as described above. In addition, you must select the port(s) through which the unit searches for and communicates with the DHCP server, as described in the following parameter, Access to DHCP. The default is Disable. Access to DHCP The Access to DHCP option enables defining the port through which the unit searches for and communicates with a DHCP server. Select from the following options: ! From Wireless Link Only ! From Ethernet Only ! From Both Ethernet and Wireless Link The default for Access Units is From Ethernet Only. The default for Subscriber Units is From Wireless Link Only. Show IP Parameters The Show IP Parameters option displays the current values of the IP parameters, including the Run Time IP Address, Run Time Subnet Mask and Run Time Default Gateway Address.
Chapter 4 - Operation and Administration BreezeACCESSS VL System Manual 4-40 Air Interface Parameters The Air Interface Parameters menu enables viewing the current Air Interface parameters defined for the unit and configuring new values for each of the relevant parameters. Country Code and Sub Bands Each country has its own regulations regarding operation modes and parameters such as allowable frequencies and bandwidth, the need to employ an automatic mechanism for detection and avoidance of frequencies used by radar systems, maximum transmit power at each of the supported modulation levels and the ability to use burst transmissions. To efficiently manage these country dependent parameters, each unit has a ‘Country Code’ parameter and a set of accompanying parameters, which depend on this country code. Where more than one set of parameters can be used, the available sets are defined as Sub Bands, selectable through the Frequency configuration menu. ESSID Parameters The ESSID (Extended Service Set ID) is a string used to identify a wireless network and to prevent the unintentional merging of two wireless networks or two sectors in the same network. Typically, a different ESSID is defined for each AU. To facilitate easy addition of SUs to an existing network without a prior knowledge of which specific AU will serve it, and to support the Best AU feature, a secondary "global" ESSID, namely "Operator ESSID", can be configured in the AU. If the Operator ESSID Option is enabled at the AU, the Beacon frames transmitted by it will include both the ESSID and Operator ESSID. The SU shall regard such frames if either the ESSID or the Operator ESSID matches it own ESSID. The ESSID of the AU with which the SU is eventually associated is defined as the Run-Time ESSID of the SU. Typically, the initial ESSID of the SU is configured to the value of the Operator ESSID. Once the SU has become associated with a specific AU, its ESSID can be reconfigured to the value of the ESSID of the AU. ESSID The ESSID parameter defines the ESSID of the unit. Valid values: A string of up to 31 printable ASCII characters. The default value is ESSID1.
Menus and Parameters Manual Revision 1.0 4-41 NOTE The ESSID string is case sensitive. Operator ESSID Parameters (AU only) The Operator ESSID Parameters submenu includes the following parameters: Operator ESSID Option The Operator ESSID Option enables or disables the use of Operator ESSID for establishing association with SUs. The default is Enable. Operator ESSID The Operator ESSID parameter defines the Operator ESSID. Valid values: A string of up to 31 printable ASCII characters. The default value is ESSID1. NOTE The Operator ESSID string is case sensitive. Frequency Definition Parameters The parameters that determine the frequency to be used are set in the AU. The SU should be configured with a minimal set of parameters to ensure that it will be able to automatically detect and use the frequency used by the AU, including possible changes in this frequency. To simplify the installation process the SU scans a definable frequencies subset after power-up. If the Best AU feature is enabled, the SU will scan the defined subset and the operating frequency will be determined by the Best AU mechanism (including the optional use of the Preferred AU feature). Otherwise the SU will try to associate with the first AU it finds. If no AU is found, the SU will start another scanning cycle. Each unit is delivered with one or more pre-configured Sub-Bands, according to the country code. These sets of parameters include also the frequencies that can be used and the bandwidth. If more than one Sub-Band is available, the sub-band to be used can be selected in both the AU and the SU. If only one Sub-Band is supported, then the sub-band selection option is not available.
Chapter 4 - Operation and Administration BreezeACCESSS VL System Manual 4-42 In some regions, it is important to ensure that wireless access equipment does not interfere with certain radar systems in the 5 GHz band. In case radar is being detected, the wireless access network should move automatically to a frequency that does not interfere with the radar system. The country dependent set of parameters includes also an indication whether DFS (Dynamic Frequency Selection) should be used. The DFS algorithm is designed to detect and avoid operation in channels with radar activity. If the current sub-band does not support DFS, then the DFS parameters configuration submenu is not available. When the DFS Option is enabled, the AU monitors the spectrum continuously, searching for signals with a specific pattern indication radar activity. Upon detecting radar activity, the AU immediately stops transmitting on this frequency and starts looking for another radar-free frequency. The subset of viable frequencies is configurable. The AU maintains a continuously updated database of all applicable frequencies, where each frequency is marked as Radar Free, Radar Detected or Adjacent to Radar. The AU attempts to check a new frequency only if it is marked as Radar Free. If a radar activity was detected on a certain frequency, it will be marked in the database as a Radar Detected frequency. The AU will not attempt to check for radar activity in frequencies marked as Radar Detected. A certain time after detecting radar activity on a frequency, it will be removed from the list of Radar Detected frequencies and will be marked as Radar Free. If radar activity was detected on a certain frequency, adjacent channels should not be used as well, according to the bandwidth. For instance, if the bandwidth is 20 MHz, then if radar activity was detected in 5800 MHz, frequencies 5790 MHz and 5810 MHz should not be used as well. These frequencies are marked in the database as Adjacent to Radar, and will be treated the same as Radar Detected frequencies. Before ceasing transmission on the frequency where radar signals had been detected, the AU sends a special disassociation message to its associated SUs. This message includes an indication whether the SUs should wait for this AU. If the SUs should wait, the message includes also the waiting time. During this time each SU searches for the AU in the defined frequencies subset. If the AU was not found within the waiting time, or if a waiting request was not included in the message, the SU starts searching for any AU, using the Best AU mechanism if applicable.
Menus and Parameters Manual Revision 1.0 4-43 Frequency Definition Submenu in AU The Frequency Definition submenu in AU includes the following parameters: Sub Band Select This parameter is available only if the country code supports two or more Sub Bands. For information on how to view the Sub Bands supported by the unit and the supported parameters’ values and options, refer to Show Country Dependent Parameters on page 4-9. The range depends on the number of Sub Bands supported by the country code. The default selection is Sub Band 1. Frequency The Frequency parameter defines the transmit/receive frequency when the DFS Option is not enabled. If the DFS Option is enabled, it sets the initial operational frequency upon starting the DFS mechanism the first time. The range depends on the selected Sub Band. The default is the lowest frequency in the Sub Band. DFS Parameters The DFS Parameters submenu is available only if DFS is supported by the current Sub Band. The DFS Parameters submenu includes the following parameters: DFS Option The DFS Option enables or disables the radar detection and dynamic frequency selection mechanism. The default is Enable. Frequency Subset Definition The Frequency Subset Definition parameter defines the frequencies that will be used in the DFS mechanism. The available frequencies according to the Sub Band are displayed, and each of the frequencies in the list is associated with an index. The frequencies subset can be defined by entering the indexes of the required frequencies, or “A” to select all available frequencies. The default is the complete list of frequencies available in the Sub Band.
Chapter 4 - Operation and Administration BreezeACCESSS VL System Manual 4-44 Channel Check Time The Channel Check Time defines the time allocated for checking whether there is a radar activity on a new frequency after power up or after trying to move to a new frequency upon detecting radar activity on the previously used frequency. During this time the AU does not transmit. The range is 1 to 3600 seconds. The default is 60 seconds. Channel Avoidance Period The Channel Avoidance Period defines the time that the frequency will remain marked in the database as Radar Detected or Adjacent to Radar after detecting radar activity. These frequencies will not be used when searching for a new frequency. Once this time has elapsed, the unit frequency’s marking will change to Radar Free. The range is 1 to 60 minutes. The default is 30 minutes. SU Waiting Option The SU Waiting Option defines whether the disassociation message sent by the AU, after detecting radar activity on the current frequency, will include a message instructing the SU to search only for the AU before attempting to search for another AU. The message includes also the time period during which the SU should not search for any other AU. The waiting tine is the Channel Check Time plus 5 seconds. The default is Enable. Minimum Pulses to Detect The Minimum Pulses to Detect parameter defines the minimum number of radar pulses that should be detected before reaching a decision that radar is active on the channel. The range is from 1 to 100 pulses. The default is 6 pulses.
Menus and Parameters Manual Revision 1.0 4-45 Clear Radar Detected Channels After Reset When the Clear Radar Detected Channels After Reset is enabled, than after the next reset all viable frequencies will be marked in the database as Radar Free, including frequencies previously marked as either Radar Detected or Adjacent to Radar. In addition, the AU will start operation using its default frequency. The default is Disable. Show DFS Settings And Data Upon selecting the Show DFS Settings and Data, the values of all DFS parameters and the current operating frequency will be displayed. The current defined frequency subset as well as the defined subset (to be used after the next reset) are also displayed. In addition, all the applicable frequencies will be displayed together with their status in the database (Radar Free, Radar Detected or Adjacent to Radar). Country Code Learning by SU This feature support simplified installation and updates processes by enabling the SU to adapt the Country Code used by the AU. The AU advertises its country code in every beacon and association response message. Upon synchronization the SU shall check if its country code and the country code received from the AU are the same. If they are not the same and the Country Code Learning by SU is enabled, the SU shall use the AU’s country code: the country code derived limitations shall be forces and the following parameters shall be set according to new country definitions: ! Maximum TX Power (per modulation level) shall be set to the maximum defined by country code. ! TX Power (per modulation level) shall be set to the maximum defined by country code. ! The Modulation Level shall be set to the maximum modulation level defined by country code. ! The Multicast Modulation Level shall be set to the minimum modulation level defined by country code. ! The Burst Mode shall be set to enable if the country code supports burst mode, and the burst duration shall be set to default.
Chapter 4 - Operation and Administration BreezeACCESSS VL System Manual 4-46 After country code learning (adaptation) the unit is automatically reset. Before this automatic reset, if the unit is running from shadow version, the versions must be swapped and the running version must be set as main. This is done to avoid returning to the previous version, which shall happen automatically after the reset. The default is Enable. Show Frequency definitions Upon selecting Show Frequency Definitions, the selected Sub Band and Frequency are displayed. In addition, all the parameters displayed upon selecting Show DFS Settings and Data are also displayed. Frequency Definition Submenu in SU Sub Band Select This parameter is available only if the country code supports two or more Sub Bands. For information on how to view the Sub Bands supported by the unit and the supported parameters’ values and options, refer to Show Country Dependent Parameters on page 4-9. The range depends on the number of Sub Bands supported by the country code. The default selection is Sub Band 1. Frequency Subset Definition The Frequency Subset Definition parameter defines the frequencies that will be used in by the SU when scanning for an AU. The available frequencies according to the Sub Band are displayed, and each of the frequencies in the list is associated with an index. The frequencies subset can be defined by entering the indexes of the required frequencies, or “A” to select all available frequencies. The default is the complete list of frequencies available in the Sub Band. Show Frequency Definitions Upon selecting the Show Frequency Definitions, the selected Sub Band parameters and the current operating frequency will be displayed. The current defined frequency subset as well as the defined subset (to be used after the next reset) are also displayed.
Menus and Parameters Manual Revision 1.0 4-47 Best AU Parameters (SU) An SU that can communicate with more than one AU using the same ESSID may become associated with the first AU it "finds", not necessarily the best choice in terms of quality of communication or other factors such as number of SUs serviced by each AU. The same limitation also exists if only one AU in the neighborhood has an ESSID identical to the one used by the SU, since it is not always necessarily the best choice. The topology of a fixed access network is constantly changing. Changes in base station deployment and subscriber density can accumulate to create substantial changes in SU performance. The quest for load sharing together with the desire to create best throughput conditions for the SU created the need for the Best AU feature, to enable a SU to connect to the best AU in its neighborhood. When the Best AU feature is used, each of the AUs is given a quality mark based on the level at which it is received by the SU. The SU scans for a configured number of cycles, gathering information from all the AUs it can communicate with. At the end of the scanning period, the SU reaches a Best AU decision according to the information gathered. The AU with the highest quality mark is selected as the Best AU, and the SU will immediately try to associate with it. The quality mark given to each AU depends on the level at which it is received by the SU. The Best AU selection mechanism can be overridden by defining a specific AU as the preferred AU. NOTE Although the SU selects the Best AU based on long-term conditions prior to the decision time, it may not always be connected to the instantaneous Best AU at any given time. Note also that the decision is done only once during the scanning interval. The decision may not remain the optimal one for ever. If there are significant changes in deployment of neighboring AUs and the SUs served by them, overall performance may be improved if the applicable SUs are reset intentionally so as to re-initiate the Best AU decision process. The Best AU Parameters menu includes the following options: Best AU Support The Best AU Support option enables or disables the Best AU selection feature. The default is Disable. NOTE If the Best AU feature is not used, the SU associates with the first AU it finds whose ESSID or Operator ESSID is identical to its own ESSID.
Chapter 4 - Operation and Administration BreezeACCESSS VL System Manual 4-48 Number Of Scanning Attempts When the Best AU option is enabled, the SU gathers information on neighboring AUs for approximately 2 seconds on each of the scanned frequencies. The Number of Scanning Attempts parameter defines the number of times that the process will be repeated for all relevant frequencies. A higher number may result in a better decision at the cost of an increased scanning time during which the SU is not operational. Valid values: 1 - 255. Default value: 4. Preferred AU MAC Address The Preferred AU MAC Address parameter defines a specific AU with which the SU should associate. Gaining control of the SUs association is a powerful tool in network management. The Preferred AU MAC Address parameter is intended for applications where there is a need to dictate the preferred AU with whom the SU should associate. To prevent the SU from associating with the first viable AU it finds, the Best AU Support mechanism should be enabled. Once the SU has identified the preferred AU based on its MAC address, it will associate with it and terminate the scanning process. If the preferred AU is not found, the SU will associate with an AU according to the decision reached using the best AU algorithm. Valid values: A MAC address string. The default value for the Preferred AU MAC Address is 00-00-00-00-00-00 (12 zeros), meaning that there is no preferred AU. Show Best AU Parameters and Data The Show Best AU Parameters and Data option displays the applicable information: The Neighboring AU Data table displays for each AU that the unit can communicate with the following details: ! MAC Address ! SNR of the received signal ! Mark - The computed quality mark for the AU.
Menus and Parameters Manual Revision 1.0 4-49 ! Full - The association load status of the AU. It is defined as full if the number of SUs associated with the AU has reached the maximum allowed according to the value of the Maximum Number of Associations parameter. An AU whose associations load status is full cannot be selected as the Best AU, even if its' computed mark is the highest. ! ESSID - The ESSID of the AU. In addition to the neighboring AU data table, the following information is displayed: ! Best AU Support ! Preferred AU MAC Address ! Number of Scanning Attempts ! Associated AU MAC Address (the MAC address of the selected AU) Scanning Mode (SU only) The Scanning Mode parameter defines whether the SU will use Passive or Active scanning when searching for an AU. In passive scanning, the SU “listens” to the wireless media for approximately two seconds at each frequency, searching for beacons. The disassociation period, which is the time from the moment the link was lost until the SU decides that it should start searching for another AU, is approximately seven seconds. In some situations when there is a high probability that SUs might need to roam among different AUs, the use of active scanning enables to significantly reduce the link establishment time. This is achieved by using shorter dwell periods, transmitting a Probe Request at each frequency. This reduces the time spent at each frequency as well as the disassociation period. When DFS Option is enabled, Scanning Mode is forced to Passive. The default selection is Passive.
Chapter 4 - Operation and Administration BreezeACCESSS VL System Manual 4-50 Power Control Parameters The Automatic Transmit Power Control (ATPC) algorithm simplifies the installation process and ensures optimal performance while minimizing interference to other units. This is achieved by automatically adjusting the power level transmitted by each SU according to the actual level at which it is received by the AU. To support proper operation of the system with optimal performance and minimum interference between neighboring sectors, the ATPC algorithm should be enabled in all units. The algorithm is controlled by the AU that calculates for each received frame the average SNR at which it receives transmissions from the specific SU. The average calculation takes into account the previous calculated average, thus reducing the effect of short temporary changes in link conditions. The weight of history (the previous value) in the formula used for calculating the average SNR is determined by a configurable parameter. In addition, the higher the time that has passed since the last calculation, the lower the impact of history on the calculated average. If the average SNR is not in the configured target range, the AU transmits to the SU a power-up or a power-down message. The target is that each SU will be received at an optimal level, or as high (or low) as possible if the optimal range cannot be reached because of specific link conditions. Each time that the SU tries to associate with the AU (following either a reset or loss of synchronization), it will initiate transmissions using its' Transmit Power parameters. If after a certain time the SU does not succeed to synchronize with the AU, it will start increasing the transmit power level. In an AU the maximum supported transmit power is typically used to provide maximum coverage. However, there may be a need to decrease the transmitted power level in order to support relatively small cells and to minimize the interference with the operation of neighboring cells, or for compliance with local regulatory requirements. In some cases the maximum transmit power of the SU should be limited to ensure compliance with applicable regulations or due to other reasons. Different power levels may be used for different modulation levels to optimize performance taking into account the different modulation schemes as well as possible regulatory restrictions.
Menus and Parameters Manual Revision 1.0 4-51 Transmit Power The Transmit Power parameters are defined separately for different modulation levels. Note that the supported modulation levels depend on the Min modulation Level and Max Modulation Level defined for the applicable Sub Band. In the AU, the Transmit Power parameter defines the fixed transmit power level and is not a part of the ATPC algorithm. In the SU, The Initial Transmit Power parameter defines the fixed transmit power level when the ATPC algorithm is disabled. If the ATPC Option is enabled the value configured for this parameter serves for setting the initial value to be used by the ATPC algorithm after either power up or loosing synchronization with the AU. The minimum value for the Transmit Power Parameters is -10 dBm. (The ATPC may reduce the actual transmit power of the SU to lower values). The maximum value of the Transmit Power Parameter depends on several unit properties and parameters: ! The HW revision of the unit ! The modulation level ! The Maximum Allowed Tx Power as defined for the applicable Sub Band. ! The Maximum EIRP as defined for the applicable Sub Band, together with the value of the Antenna Gain. In certain countries the Maximum EIRP of some equipment types cannot exceed a certain value. In these cases the Transmit Power cannot exceed the value of (Maximum EIRP – Antenna Gain). ! Maximum Tx Power parameter (in SU only) For information on how to view the Sub Bands supported by the unit and the supported parameters’ values and options, refer to Show Country Dependent Parameters on page 4-9. The unit calculates the maximum allowed Transmit Power according to the unit properties and parameters listed above, and displays the allowed range when a Transmit Power parameter is selected. The default Transmit Power is the highest allowed value. Maximum Tx Power (SU only) The Maximum Tx Power parameter limits the maximum transmit power that can be reached by the ATPC algorithm. It also sets the upper limits for the Transmit Power parameters.
Chapter 4 - Operation and Administration BreezeACCESSS VL System Manual 4-52 The minimum value for the Maximum Tx Power is -10 dBm. The maximum value depends on several unit properties and parameters: ! The HW revision of the unit ! The modulation level ! The Maximum Allowed Tx Power as defined for the applicable Sub Band. ! The Maximum EIRP as defined for the applicable Sub Band, together with the value of the Antenna Gain. In certain countries the Maximum EIRP of some equipment types cannot exceed a certain value. In these cases the Transmit Power cannot exceed the value of (Maximum EIRP – Antenna Gain). For information on how to view the Sub Bands supported by the unit and the supported parameters’ values and options, refer to Show Country Dependent Parameters on page 4-9. The unit calculates the maximum allowed Maximum Tx Power according to the unit properties and parameters listed above, and displays the allowed range when the Maximum Tx Power parameter is selected. The default Maximum Tx Power is the highest allowed value. ATPC Parameters in AU ATPC Option The ATPC Option enables or disables the Automatic Transmit Power Control (ATPC) algorithm. The default is Enable. ATPC Minimum SNR Level The Minimum SNR Level defines the lowest SNR at which you want each SU to be received at the AU (the lower limit of the optimal reception level range). Available values: 4 to 60 (dB). Default value: 28 (dB). ATPC Delta from Minimum SNR Level The Delta from Minimum SNR Level is used to define the highest SNR at which you want each SU to be received at the AU (the higher limit of the optimal reception level range):
Menus and Parameters Manual Revision 1.0 4-53 Max. Level=Minimum SNR Level + Delta from Minimum SNR Level. Available values: 4 to 20 (dB) for units operating in the 5.2, 5.4 and 5.8 GHz bands. 11 to 20 (dB) for units operating in the 4.9 and 5.3 GHz bands. Default value: 4 (dB) for units operating in the 5.2, 5.4 and 5.8 GHz bands. 11 (dB) for units operating in the 4.9 and 5.3 GHz bands. Minimum Interval Between ATPC Messages The Minimum Interval Between ATPC Messages parameter sets the minimal time between consecutive power-up/power-down messages to a specific SU. Setting a low value for this parameter may lead to a higher overhead and an excessive rate of power level changes at the SUs. High values for this parameter increase the time it will take until the SUs reach optimal transmit power level. Available values: 1 to 3600 seconds. Default value: 30 seconds. ATPC Power Level Step The ATPC Power Level Step parameter defines the step size to be used by the SUs for incrementing/decrementing the Current Transmit Power after receiving a power-up/power-down message. If the distance between the value of the Current Transmit Power and the desired range is smaller than the step size, the power-up/power-down message will include the specific step value required for this condition. Valid range: 1-20 (dB) Default value: 5 (dB) ATPC Parameters in SU ATPC Option The ATPC Option enables or disables the Automatic Transmit Power Control (ATPC) algorithm. The parameter takes effect immediately. However, when changed from Enable to Disable, the transmit power level shall remain at the last Current Transmit Power determined by the ATPC algorithm before it was disabled. It will change to the value configured for the Initial Transmit Power parameter only after the next reset or following loss of synchronization. The default is Enable.
Chapter 4 - Operation and Administration BreezeACCESSS VL System Manual 4-54 Antenna Gain The Antenna Gain parameter enables to define the net gain of a detached antenna. The configured gain should take into account the attenuation of the cable connecting the antenna to the unit. The Antenna Gain is important especially in countries where there is a limit on the EIRP allowed for the unit; the maximum allowed value for the Transmit Power parameters cannot exceed the value of (EIRP- Antenna Gain), where the EIRP is defined in the selected Sub Band. In certain units with an integral antenna the Antenna Gain is not available as a configurable parameter. However, it is available as a read-only parameter in the applicable “Show” menus. The range is 0 – 50 (dB). A value of “Don’t Care” means that the actual value is not important. A value of “Not Set Yet” means that the unit will not transmit until the actual value (in the range 0 to 50) is configured. The unit can be configured to “Don’t Care” or “Not Set Yet” only in factory (when upgraded to SW version 2.0 from a lower version it will be set automatically to one of these options). Once a value is configured, it is not possible to reconfigure the unit to either “Don’t Care” or “Not Set Yet”. The default value depends on unit type. In SUs with integral antenna it is set to 21 (read only). The default value for AUs that are supplied with a detached antenna is in accordance with the antenna’s gain. In units supplied without an antenna the default is typically “Not Set Yet”. Cell Distance Parameters (AU only) The higher the distance of an SU from the AU that is serving it, the higher the time it takes for messages sent by one of them to reach the other. To ensure appropriate services to all SUs regardless of their distance from the AU while maintaining a high overall performance level, two parameters should be adapted to the distances of SUs from the serving AU: ! The time that a unit waits for a response message before retransmission (acknowledge time delay) should take into account the round trip propagation delay of the farthest SU. (the one-way propagation delay at 5 GHz is 3.3 microsecond/km). The higher the distance from the AU of the farthest SU served by it, the higher should be the acknowledge time delay for all units in the cell.
Menus and Parameters Manual Revision 1.0 4-55 ! To ensure fairness in the contention back-off algorithm between SUs located at different distances from the AU, the size of the time slot should also take into account the one-way propagation delay. The size of the time slot of all units in the cell should be proportional to the distance from the AU of the farthest SU served by it. The distance from the AU of the farthest SU served by it can be determined either manually or automatically. In manual mode, this distance is configured manually. In automatic mode, the AU uses a special algorithm to estimate its distance from each of the SUs it serves, determine which SU is located the farthest and use the estimated distance of the farthest SU as the maximum distance. It should be noted that if the size of the time slot used by all units is adapted to the distance of the farthest unit, than no unit will have an advantage when competing for services. However, this reduces the overall achievable throughput of the cell. In certain situations, the operator may decide to improve the overall throughput by reducing the slot size below the value required for full fairness. This means that when there is competition for bandwidth, the back-off algorithm will give advantage to SUs that are located closer to the AU. The Cell Distance Parameters menu includes the following parameters: Cell Distance Mode The Cell Distance Mode option defines whether the maximum distance of the AU from any of the SUs it serves will be determined manually (using the Maximum Cell Distance parameter) or automatically. The Options are Automatic or Manual. The default is Automatic. Maximum Cell Distance The Maximum Cell Distance parameter allows configuring the maximum distance when the Cell Distance Mode option is Manual. The range is 0 to 54 (Km). The value of 0 has a special meaning for No Compensation: Acknowledge Time Out is set to a value representing the maximum distance of 54 km. The time slot size is set to its minimal value of 9 microseconds. The default is 0 (No Compensation).
Chapter 4 - Operation and Administration BreezeACCESSS VL System Manual 4-56 Fairness Factor The Fairness Factor enables to define the level of fairness in providing services to different SU. When set to 100%, all SUs have the same probability of getting services when competing for bandwidth. If set to X%, than SUs located up to X% of the maximum distance from the AU will have advantage in getting services over SUs located farther than this distance. The range is 0 to 100 (%) The default is 100 (%). Show Cell Distance Parameters Select Show Cell Distance Parameters to view the Cell Distance parameters. In addition, the Measured Maximum Cell Distance and the MAC address of the unit that the mechanism found to be the farthest from the AU are displayed. A distance of 1 km means any distance below 2km. Arbitration Inter-Frame Spacing (AIFS) The time interval between two consecutive transmissions of frames is called Inter-Frame Spacing (IFS). This is the time during which the unit determines whether the medium is idle using the carrier sense mechanism. The IFS depends on the type of the next frame to be transmitted, as follows: ! SIFS (Short Inter-Frame Spacing) is used for certain frames that should be transmitted immediately, such as ACK and CTS frames. The value of SIFS is 16 microseconds. ! DIFS (Distributed coordination function Inter-Frame Spacing) is typically used for other frame types when the medium is free. If the unit decides that the medium is not free, it will defer transmission by DIFS plus a number of time slots as determined by the Contention Window back-off algorithm (see Minimum Contention Window on page 4-77) after reaching a decision that the medium has become free. DIFS equal SIFS plus AIFS, where AIFS can be configured to one or two time slots. Typically AIFS should be configured to two time slots. A value of 1 should only be used in one of the two units in a point-to-point link, where in the other unit the AIFS remains configured to two time slots. This ensures that the unit with AIFS configured to one has an advantage over the other unit, provided that the Minimum Contention Window parameter (see page 4-77) in both units is configured to 0 to disable the contention window back-off algorithm.
Menus and Parameters Manual Revision 1.0 4-57 The available options are 1 or 2 (time slots). The default is 2 time slots. CAUTION An AIFS value of 1 should only be used in point-to-point applications. Otherwise the default value of 2 must always be used. In a point-to-point link, only one unit should be configured to an AIFS value of 1. When both units need to transmit, the unit with an AIFS value of 1 shall have an advantage over the unit with AIFS of 2. In this case, the Minimum Contention Window parameter in both units must be configured to 0 to disable the contention window back-off algorithm. Maximum Number of Associations (AU only) The Maximum Number of Associations parameter defines the maximum number of Subscriber Units that can be associated with the selected AU, while still guaranteeing the required quality of service to customers. Available values range from 0 to 512. Default value: 512. NOTE There is no aging time for SUs. An SU is only removed from the list of associated SUs under the following conditions: a. A SNAP frame is received from another AU indicating that the SU is now associated with the other AU. b. The SU failed to respond to a certain number of consecutive frames transmitted by the AU and is considered to have "aged out". Therefore, the database of associated SUs may include units no longer associated with the AU. If the number of associated SUs has reached the value of the Maximum Number of Associations parameter, the selected AU cannot serve additional SUs. To view the current number of associated SUs, use the Display Association Info option in the MAC Address Database menu. To delete inactive SUs from the database you must reset the AU. Wireless Link Trap Threshold (AU only) The Wireless Link Trap Threshold parameter defines the threshold for the wireless quality trap, indicating that the quality of the wireless link has dropped below (on trap) or has increased above (off trap) the specified threshold. The Wireless Link Trap Threshold is in percentage of retransmissions, and the allowed range is from 1 to 100 (%). The default is 30 (%).
Chapter 4 - Operation and Administration BreezeACCESSS VL System Manual 4-58 Country Code Learning by SU This feature support simplified installation and updates processes by enabling the SU to adapt the Country Code used by the AU. The AU advertises its country code in every beacon and association response message. Upon synchronization the SU shall check if its country code and the country code received from the AU are the same. If they are not the same and the Country Code Learning by SU is enabled, the SU shall use the AU’s country code: the country code derived limitations shall be forces and the following parameters shall be set according to new country definitions: ! Maximum TX Power (per modulation level) shall be set to the maximum defined by country code. ! TX Power (per modulation level) shall be set to the maximum defined by country code. ! The Modulation Level shall be set to the maximum modulation level defined by country code. ! The Multicast Modulation Level shall be set to the minimum modulation level defined by country code. ! The Burst Mode shall be set to enable if the country code supports burst mode, and the burst duration shall be set to default. After country code learning (adaptation) the unit is automatically reset. Before this automatic reset, if the unit is running from shadow version, the versions must be swapped and the running version must be set as main. This is done to avoid returning to the previous version, which shall happen automatically after the reset. The default is Enable.
Menus and Parameters Manual Revision 1.0 4-59 Network Management Parameters The Network Management Parameters menu enables protecting the Unit from unauthorized access by defining a set of IP addresses from which the unit can be managed using protocols such as Telnet, FTP, TFTP, SNMP, DHCP and ICMP. This excludes management messages generated in the unit, such as Traps or Ping Test frames, which are not filtered. You can also determine the direction from which management access is permitted, which means from the wireless media or the wired Ethernet or both. The Network Management Parameters menu includes the following options: ! Access to Network Management ! Network Management Filtering ! Set Network Management IP address ! Delete a Network Management IP Address ! Delete All Network Management IP Addresses ! SNMP Traps Access to Network Management The Access to Network Management option defines the port through which the unit can be managed. The following options are available: ! From Wireless Link Only ! From Ethernet Only ! From Both Ethernet and Wireless Link The default selection is From Both Ethernet and Wireless Link. CAUTION Be careful not to block your access to the unit. For example, if you manage an SU via the wireless link, setting the Access to Network Management parameter to From Ethernet Only completely blocks your management access to the unit. In this case, a technician may be required to change the settings at the user's site.
Chapter 4 - Operation and Administration BreezeACCESSS VL System Manual 4-60 Network Management Filtering The Network Management Filtering option enables or disables the IP address based management filtering. If management filtering is enabled, the unit can only be managed by stations with IP addresses matching one of the entries in the Set Network Management IP Addresses option, described below, and that are connected to the unit via the defined port(s). The following options are available: ! Disable: No IP address based filtering is configured. ! Activate IP Filter on Ethernet Port: Applicable only if the Access to Network Management parameter is configured to either From Ethernet Only or From Both Ethernet and Wireless Link.

Chapter 4 - Operation and Administration BreezeACCESSS VL System Manual 4-62 Bridge Parameters The Bridge Parameters menu provides a series of parameter sets that enables configuring parameters such as control and filtering options for broadcast transmissions, VLAN support, and Type of Service prioritization. The Bridge Parameters menu includes the following options: ! VLAN Support ! ToS Parameters ! Ethernet Broadcast Filtering ! Bridge Aging Time ! Roaming Option (SU only) ! Broadcast Relaying (AU only) ! Unicast Relaying (AU only) ! MAC Address Deny List (AU only) VLAN Support The VLAN Support menu enables defining the parameters related to the IEEE 802.1Q compliant VLAN aware (Virtual LAN aware) feature of the BreezeACCESS VL units. Each VLAN includes stations that can communicate with each other, but cannot communicate with stations belonging to different VLANs. The VLAN feature also provides the ability to set traffic priorities for transmission of certain frames. The information related to the VLAN is included in the VLAN Tag Header, which is inserted in each frame between the MAC header and the data. VLAN implementation in BreezeACCESS VL units supports frame routing by port information, whereby each port is connected to only one VLAN. The VLAN Support menu includes the following parameters: ! VLAN Link Type ! VLAN ID – Data (SU only) ! VLAN ID – Management ! VLAN Forwarding ! VLAN Relaying (AU only) ! VLAN Traffic Priority
Menus and Parameters Manual Revision 1.0 4-63 VLAN ID-Data (SU only) The VLAN ID-Data is applicable only when the VLAN Link Type parameter is set to Access Link. It enables defining the VLAN ID for data frames, which identifies the VLAN to which the unit belongs. Valid values range from 1 to 4094. Default value: 1. The VLAN ID-Data affects frames received from the wireless link port, as follows: ! Only tagged frames with a VLAN ID (VID) equal to the VLAN ID-Data defined in the unit are forwarded to the Ethernet port. ! The tag headers are removed from the data frames received from the wireless link before they are transmitted on the Ethernet port. The VLAN ID-Data affects frames received from the Ethernet port, as follows: ! A VLAN Data Tag is inserted in all untagged frames received from the Ethernet port before transmission on the wireless link. The tag includes the values of the VLAN ID-Data and the VLAN Priority- Data parameters. ! Tagged frames received on Ethernet port, which are meant to be forwarded to the wireless link port, are discarded. This includes frames with tagging for prioritization purpose only. VLAN ID-Management The VLAN ID-Management is applicable for all link types. It enables defining the VLAN ID for management frames, which identifies remote stations for management purposes. This applies to all management applications using protocols such as SNMP, TFTP, ICMP (ping), DHCP and Telnet. All servers/stations using these protocols must tag the management frames sent to the unit with the value of the VLAN ID- Management parameter. Valid values: 1 to 4094 or 65535 (No VLAN). The default value is 65535. If the VLAN ID-Management is other than 65535: ! Only tagged management frames with a matching VLAN ID received on either the Ethernet or wireless link ports are forwarded to the unit.
Chapter 4 - Operation and Administration BreezeACCESSS VL System Manual 4-64 ! A VLAN Management Tag is inserted in all management frames generated by the unit before transmission on either the Ethernet or wireless link port. The tag includes the values of the VLAN ID- Management and the VLAN Priority-Management parameters. If the VLAN ID-Management is 65535 (No VLAN): ! Only untagged management frames received on either the Ethernet or wireless link ports are forwarded to the unit. ! Management frames generated by the unit are not tagged. The following table summarizes the functionality of the internal management port in accordance with the value of the VLAN ID- Management parameter. The table is valid for all link types. Refer to the VLAN Link Type - Access Link and Trunk Link options for some restrictions when configuring this parameter. Table 4-5: VLAN Management Port Functionality Action Management Port - Internal Receive from Ethernet Tagged frames, matching VID-M Untagged frames when VID-M=65535 Receive from Wireless Tagged frames, matching VID-M Untagged frames when VID-M=65535 Transmit Insert VID-M, PID-M Table Legend: ! VID-M: VLAN ID-Management ! PID-M: VLAN Priority-Management VLAN Link Type The VLAN Link Type parameter enables defining the functionality of the VLAN aware capability of the unit. The available options are Hybrid Link, Trunk Link and Access Link (Access Link option is available only in SUs). The default selection is Hybrid Link. Access Link (SU only) Access Link transfers frames while tagging/untagging them since all devices connected to the unit are VLAN unaware. Thus, the unit cannot transfer tagged frames.
Menus and Parameters Manual Revision 1.0 4-65 Table 4-6 summarizes the functionality of the data port for an Access link.

VID-D: VLAN ID-Data ! PID-D: VLAN Priority-Data Trunk Link Trunk Link transfers only tagged frames, since all devices connected to the unit are VLAN aware: Only tagged data frames received on the Ethernet or wireless link ports are forwarded. CAUTION It is not recommended that you configure a unit as a Trunk Link with the VLAN ID- Management parameter set at 65535, as it does not forward any 'NO VLAN' management frames to its other port making it impossible to manage devices connected behind the unit that are also configured with 'NO VLAN'. If the VLAN Forwarding option is enabled, a data frame received with a VLAN ID that is not a member of the unit's VLAN Forwarding List is discarded. NOTE If the VLAN Forwarding option is enabled, be sure to include the VLAN ID- Management value of all units that should be managed via the wireless port of the unit, in the Forwarding List. If the VLAN Relaying option is enabled in an AU, a data frame relayed with a VLAN ID that is not a member of the unit's VLAN Relaying List is discarded. NOTE If the VLAN Relaying option is enabled and you manage your devices from behind an SU unit, be sure to include the VLAN ID-Management value of all units to be managed when relaying via the wireless port of the AU unit, in the Relaying List. If the VLAN Forwarding option is also enabled in the AU, these VLAN IDs should also be included in the Forwarding List.

Menus and Parameters Manual Revision 1.0 4-67 VLAN Forwarding (AU and SU) The VLAN Forwarding feature is applicable for Trunk Links only. It enables defining the VLAN ID values to be included in the VLAN Forwarding List. If the Link Type is defined as a Trunk Link and the VLAN Forwarding option is enabled, a data frame received with a VLAN ID that is not a member of the unit's VLAN Forwarding List is discarded. The VLAN Forwarding submenu provides the following options: VLAN Forwarding Support The VLAN Forwarding Support option enables or disables the VLAN Forwarding feature. Available selections are Disable and Enable. The default selection is Disable. Add Forwarding VLAN ID The Add Forwarding VLAN ID option enables adding a VLAN ID to the VLAN Forwarding List. One VLAN ID can be entered at a time. The maximum number of VLAN IDs in the VLAN Forwarding List is 20. Valid values are 1 to 4094. Remove Forwarding VLAN ID The Remove Forwarding VLAN ID option enables removing a VLAN ID from the VLAN ID Forwarding List. Valid values are VID values (from 1 to 4094) that are included in the VLAN Forwarding List. Show VLAN ID Forwarding List The Show VLAN Forwarding List option displays the values of the VLAN IDs included in the VLAN Forwarding List. NOTE If the VLAN ID Forwarding List is empty and the VLAN Forwarding Support is set to Enable, then all data frames are discarded. If VLAN Relaying Support and VLAN Forwarding Support are both enabled, then all VLAN IDs configured in the Relaying List must also be configured in the Forwarding List.
Chapter 4 - Operation and Administration BreezeACCESSS VL System Manual 4-68 VLAN Relaying (AU only) The VLAN Relaying feature is applicable for Trunk Links only. It enables defining the VLAN ID values to be included in the VLAN Relaying List. If the Link Type is defined as Trunk Link and the VLAN Relaying Support option is enabled, a frame relayed from the wireless link, which is a frame received from the wireless link that should be transmitted back through the wireless link, with a VLAN ID that is not a member of the unit's VLAN Relaying List, is discarded. If VLAN Forwarding Support is also enabled, it is necessary to configure all the VLAN IDs in the Relaying List also in the Forwarding List to enable the relaying operation. The VLAN Relaying menu provides the following options: VLAN Relaying Support The VLAN Relaying Support option enables or disables the VLAN Relaying feature. Available selections are Disable and Enable. The default selection is Disable. Add Relaying VLAN ID The Add Relaying VLAN ID option enables adding a VLAN ID to the VLAN Relaying List. One VLAN ID can be entered at a time. The maximum number of VLAN IDs in the VLAN Relaying List is 20. Valid values are 1 to 4094. Remove Relaying VLAN ID The Remove Relaying VLAN ID option enables removing a VLAN ID from the VLAN ID Relaying List. Valid values are VID values (from 1 to 4094)) that are included in the VLAN Relaying List. Show VLAN ID Relaying List The Show VLAN Relaying option displays the values of the VLAN IDs included in the VLAN Relaying List. NOTE If the VLAN ID Relaying List is empty and the VLAN Relaying Support is Enabled, then all data frames relayed from the wireless link are discarded. If VLAN Relaying Support and VLAN Forwarding Support are both enabled, then all VLAN IDs configured in the Relaying List must also be configured in the Forwarding List.
Menus and Parameters Manual Revision 1.0 4-69 VLAN Traffic Priority Each packet to be transmitted to the wireless link is transferred to one of three queues: Low, Mid and High. Packets in the High queue have the highest priority for transmission, and those in the Low queue have the lowest priority. BreezeACCESS Subscriber and Access units support layer-2 traffic prioritization according to the IEEE 802.1p standard. The priority field in the 802.1Q header tag can have a value in the range 0 to 7. This value determines the relative priority of the packet. Packets received from the Ethernet port that have a priority higher than the value of the VLAN Priority Threshold are routed to the Mid queue. Since the system also supports layer 3 prioritization, based on ToS, packets with precedence in the ToS field higher than the value of the ToS Precedence Threshold parameter are also routed to the Mid queue. This is applicable to both tagged and untagged frames. All other packets received from the Ethernet port are routed to the Low queue. Control and wireless management frames generated in the unit are routed to the High queue. Any frame coming from the Ethernet port, which is meant to reach another BreezeACCESS unit via the wireless port (as opposed to messages intended for stations behind other BreezeACCESS units), is sent to the High queue, regardless of the priority configuration. NOTE The prioritization mechanism is disabled when the traffic rate reaches the maximum information rate supported by the SU. The VLAN Traffic Priority menu includes the following parameters: ! VLAN Priority – Data (SU only) ! VLAN Priority – Management ! VLAN Priority Threshold VLAN Priority - Data (SU only) The VLAN Priority - Data is applicable for Access Links only. It enables configuring the value of the VLAN Priority field for data frames transmitted to the wireless link. All data frames are routed to the Low queue. This parameter only impacts the way that other VLAN aware devices handle the packet.
Chapter 4 - Operation and Administration BreezeACCESSS VL System Manual 4-70 Valid values range from 0 to 7. The default value is 0. NOTE Packets Received from the Ethernet port with a ToS Precedence value higher than the defined ToS Precedence Threshold are routed to the Mid queue. VLAN Priority - Management The VLAN Priority - Management enables defining the value of the VLAN Priority field for management frames in units with VLAN ID Management that is other than 65535. All management frames are routed to the High queue. This parameter only impacts the way other VLAN aware devices handle the packet. Valid values range from 0 to 7. The default value is 4 for SUs and 0 for AUs. VLAN Priority Threshold The VLAN Priority Threshold is applicable for Trunk and Hybrid Links only. It enables defining the value of the VLAN Priority Threshold. This parameter impacts the way the unit handles tagged packets received from the Ethernet port. Since the system supports both layer 2 and layer 3 prioritization, a frame is routed to the Mid queue if either of the following conditions are met: ! The precedence in the ToS field is higher than the value of the ToS Precedence Threshold parameter. This is applicable to both tagged and untagged frames. ! The VLAN Priority field in a tagged frame is higher than the value of the VLAN Priority Threshold parameter. Valid values range from 0 to 7. The default value is 3. Show VLAN Parameters The Show VLAN Parameters option displays the current values of the VLAN support parameters.
Menus and Parameters Manual Revision 1.0 4-71 ToS Parameters ToS Precedence Threshold The ToS Precedence Threshold parameter enables defining ToS based prioritization in accordance with the precedence bits of the ToS field in the IP header. An IP packet received from the Ethernet port is routed to the Mid queue if any one of the following conditions is met: ! The precedence in the ToS field is higher than the value of the ToS Precedence Threshold parameter. This is applicable to both tagged and untagged frames. ! The VLAN Priority field in a tagged frame (Hybrid or Trunk Link) is higher than the value of the VLAN Priority Threshold parameter. All other packets received from the Ethernet port are routed to the Low queue. Valid values are 0 to 7. The default value is 3. NOTE The prioritization mechanism is disabled when the traffic rate reaches the maximum information rate supported by the SU. Ethernet Broadcast Filtering (SU only) The Ethernet Broadcast Filtering menu enables defining the layer 2 (Ethernet) broadcast and multicast filtering capabilities for the selected SU. Filtering the Ethernet broadcasts enhances the security of the system and saves bandwidth on the wireless media by blocking protocols that are typically used in the customer's LAN but are not relevant for other customers, such as NetBios, which is used by the Microsoft Network Neighborhood. Enabling this feature blocks Ethernet broadcasts and multicasts by setting the I/G bit at the destination address to 1. This feature should not be enabled when there is a router behind the SU. The Ethernet Broadcast Filtering menu includes the following parameters: ! Filter Options ! DHCP Broadcast Override Filter ! PPPoE Broadcast Override Filter ! ARP Broadcast Override Filter
Chapter 4 - Operation and Administration BreezeACCESSS VL System Manual 4-72 Filter Options The Filter Options enables defining the Ethernet Broadcast filtering functionality of the unit. Select from the following options: ! Disable, which means no Ethernet Broadcast Filtering. ! On Ethernet Port Only, which filters broadcast messages received from the Ethernet port. ! On Wireless Port Only, which filters broadcast messages received from the wireless link port. ! On Both Ethernet and Wireless Ports, which filters broadcast messages received from both the Ethernet and wireless link ports. The default selection is Disable. DHCP Broadcast Override Filter The DHCP Broadcast Override Filter option enables or disables the broadcasting of DHCP messages. Even if according to the selected option in the Filter Options parameter, broadcast messages should be filtered, DHCP broadcasts are transmitted if this parameter is set to Enable. Select from the following options: ! Disable, which means that DHCP Broadcast messages are filtered or transmitted according to the general filtering criteria in the Filter Options parameter. ! Enable, which means that DHCP Broadcast messages are transmitted regardless of the selected value of the Filter Options parameter. The default selection is Disable. PPPoE Broadcast Override Filter The PPPoE Broadcast Override Filter option enables or disables the broadcasting of PPPoE (Point to Point Protocol over Ethernet) messages. Even if according to the selected option in the Filter Options parameter, broadcast messages should be filtered, PPPoE broadcasts are transmitted if this parameter is set to Enable. Select from the following options: ! Disable, which means that PPPoE Broadcast messages are filtered or transmitted according to the general filtering criteria in the Filter Options parameter.
Menus and Parameters Manual Revision 1.0 4-73 ! Enable, which means that PPPoE Broadcast messages are transmitted regardless of the selected value of the Filter Options parameter. The default selection is Disable. ARP Broadcast Override Filter The ARP Broadcast Override Filter option enables or disables the broadcasting of ARP messages. Even if according to the selected option in the Filter Options parameter, broadcast messages should be filtered, ARP broadcasts are transmitted if this parameter is set to Enable. Select from the following options: ! Disable, which means that ARP messages are filtered or transmitted according to the general filtering criteria in the Filter Options parameter. ! Enable, which means that ARP messages are transmitted regardless of the selected value of the Filter Options parameter. The default selection is Enable. Bridge Aging Time The Bridge Aging Time parameter enables selecting the bridge aging time for learned addresses of devices on both the wired and wireless sides, not including BreezeACCESS VL units. The available range is 20 to 2000 seconds. The default value is 300 seconds. Broadcast Relaying (AU only) The Broadcast Relaying option enables selecting whether the unit performs broadcast relaying. When the Broadcast Relaying parameter is enabled, broadcast packets originating from devices on the wireless link are transmitted by the AU back to the wireless link devices, as well as to the wired LAN. If disabled, these packets are sent only to the local wired LAN and are not sent back to the wireless link. Disable the broadcast relaying only if all broadcast messages from the wireless link are certain to be directed to the wired LAN. The default selection is Enable.
Chapter 4 - Operation and Administration BreezeACCESSS VL System Manual 4-74 Unicast Relaying (AU only) The Unicast Relaying option enables selecting whether the unit performs unicast relaying. When the Unicast Relaying parameter is enabled, unicast packets originating from devices on the wireless link can be transmitted back to the wireless link devices. If disabled, these packets are not sent to the wireless link even if they are intended for devices on the wireless link. Disable the Unicast Relaying parameter only if all unicast messages from the wireless link are certain to be directed to the local wired LAN. The default selection is Enable. MAC Address Deny List (AU only) The MAC Address Deny List submenu enables to define units that are not authorized to receive services. The AU will not provide services to a unit whose MAC Address is included in the deny list. This feature enables to disconnect units from the services in cases such as when the user had fraudulently succeeded to configure the unit to values different than his subscription plan. The deny list can include up to 100 MAC Addresses. The MAC Address Deny List submenu includes the following: Add MAC Address to Deny List Select Add MAC Address to Deny List to add a MAC Address to the Deny List. Remove MAC Address from Deny List Select Remove MAC Address from Deny List to remove a MAC Address from the Deny List. Show MAC Address Deny List Select Show MAC Address Deny List to display the current list of MAC Addresses included in the Deny List.
Menus and Parameters Manual Revision 1.0 4-75 Roaming Option (SU only) The Roaming Option defines the roaming support of the unit. When roaming is not expected, it is preferable to set this parameter to Disable. This will cause the unit to start scanning for another AU after loosing connectivity with the current AU only after 7 seconds during which no beacons were received from the current AU. This will prevent scanning for another AU in cases where no beacons were received due to a short temporary problem. When set to Enable, the SU will wait only one second before it starts scanning for another AU. In addition, when the Roaming Option is enabled, the SU will send Roaming SNAP messages upon associating with a new AU. This enables fast distribution of the new location for all clients that are behind the SU. In this case, the SU will send multicast SNAP messages via the wireless link each time it associates with a new AU, except for the first association after reset. The SU will send one SNAP message for each client learned on its Ethernet port, based on its bridging table. In the SNAP message the clients’ MAC address is used as the source address. The AU that receives this SNAP message learns from it the new location of the clients. It forwards the SNAP to other AUs and Layer-2 networking equipment via its Ethernet port, to facilitate uninterrupted connectivity and correct routing of transmissions to these clients. The new AU as well as the previous AU with which the SU was associated, will forward the SNAP messages to all other SUs associated with them. The default is Disable. Show Bridge Parameters The Show Bridge Parameters option displays the current values of the Bridge parameters.
Chapter 4 - Operation and Administration BreezeACCESSS VL System Manual 4-76 Performance Parameters The Performance Parameters menu enables defining a series of parameters that control the method by which traffic is transmitted through the BreezeACCESS VL wireless access network. The Performance Parameters menu includes the following parameters: ! RTS Threshold ! Minimum Contention Window ! Maximum Contention Window ! Multicast Modulation Level (AU only) ! Maximum Modulation Level ! Average SNR Memory Factor ! Number of HW Retries ! Burst Mode ! Adaptive Modulation Algorithm RTS Threshold The RTS Threshold parameter defines the minimum frame size that requires an RTS/CTS (Request To Send/Clear To Send) handshake. Frames whose size is smaller than the RTS Threshold value are transmitted directly to the wireless link without being preceded with RTS frames. Setting this parameter to a value larger than the maximum frame size eliminates the RTS/CTS handshake for frames transmitted by this unit. The available values range from 20 to 1600 bytes. The default value is 60 bytes for SUs and 1600 for AUs. It is recommended that these values be used to ensure that RTS/CTS is never used in the AU.
Menus and Parameters Manual Revision 1.0 4-77 Minimum Contention Window The Minimum Contention Window parameter determines the time that a unit waits from the time it has concluded that there are no detectable transmissions by other units until it attempts to transmit. The BreezeACCESS VL system uses a special mechanism based on detecting the presence of a carrier signal and analyzing the information contained in the transmissions of the AU to estimate the activity of other SUs served by the AU. The target is to minimize collisions in the wireless media resulting from attempts of more than one unit to transmit at the same time. The system uses an exponential Back-off algorithm to resolve contention between several units that want to access the wireless media. The method requires each station to choose a random number N between 0 and a given number C each time it wants to access the media. The unit will attempt to access the media only after a time equal to DIFS (for more details refer to Arbitration Inter-Frame Spacing on page 4-56) plus N time slots, always checking if a different unit has accessed the media before. Each time the unit tried to transmit and a collision happened; the maximum number C used for the random number selection will be increased to the next available value. The available values are 7, 15, 31, 63, 127, 255, 511 and 1023. The Minimum Contention Window parameter is the first maximum number C used in the back-off algorithm. The higher the number of SUs served by the same AU, the higher the Minimum Contention Window for each SU should be. The available values are 0, 7, 15, 31, 63, 127, 255, 511 and 1023. A value of 0 means that the contention window algorithm is not used and that the unit will attempt to access the media immediately after a time equal to DIFS. The default value is 15. CAUTION A value of 0 disables the contention window back-off algorithm. It should only be used in point-to-point applications. For more details on configuring units in a point-to-point link refer to Arbitration Inter-Frame Spacing on page 4-56.
Chapter 4 - Operation and Administration BreezeACCESSS VL System Manual 4-78 Maximum Contention Window The Maximum Contention Window parameter defines the upper limit for the maximum number C used in the back-off algorithm as described in Minimum Contention Window above. The available values are 7, 15, 31, 63, 127, 255, 511 and 1023. The default value is 1023. Multicast Modulation Level (AU only) The Multicast Modulation Level parameter defines the modulation level used for transmitting multicast and broadcast data frames. Multicast and broadcast transmissions are not acknowledged; therefore if a multicast or broadcast transmission is not properly received there is no possibility of retransmitting. It is recommended that you set a lower modulation level for broadcast and multicast frame transmissions to increase the probability that they are received without errors. The Multicast Modulation Level parameter is applicable only to data frames. Beacons and other wireless management and control frames are always transmitted at the lowest modulation level according to the Sub Band. The minimum value for the Multicast Modulation Level is defined by the Sub Band in use. The maximum value for the Multicast Modulation Level is defined by the Sub Band in use and the HW revision of the unit. Units with HW revision A support a maximum value of 7, while units with HW revision B and higher support a maximum value of 8. For information on how to view the Sub Bands supported by the unit and the supported parameters’ values and options, refer to Show Country Dependent Parameters on page 4-9. The default value is the lowest supported modulation level.
Menus and Parameters Manual Revision 1.0 4-79 Maximum Modulation Level When the Adaptive Modulation Algorithm (see Adaptive Modulation Algorithm on page 4-81) is enabled, it changes the modulation level dynamically according to link conditions. The purpose is to increase the probability of using the maximum possible modulation level at any given moment. Although the algorithm will avoid using modulation levels that are too high for the prevailing link conditions, it might be desired under certain conditions to limit the use of higher modulation levels. If the link quality is not sufficient, it is recommended that the maximum modulation level be decreased, since higher modulation levels increase the error rate. In such conditions, a higher Maximum Modulation Level increases the number or retransmissions before the modulation level is being reduced by the Adaptive Modulation Algorithm. A high number of retransmissions reduces the overall throughput of the applicable SU as well as all other SUs associated with the same AU. The link quality can be estimated based on the SNR measurement of the SU at the AU, which can be viewed in the MAC Address Database option in the Site Survey menu. If the measured SNR is less than a certain threshold, it is recommended that the maximum modulation level of the SU be decreased in accordance with Table 4-9, using the values of typical sensitivity. It is recommended to add a 2 dB safety margin to compensate for possible measurement inaccuracy or variance in the link quality. NOTE The SNR measurement at the AU is accurate only when receiving transmissions from the applicable SU. If necessary, use the Ping Test utility in the Site Survey menu to verify data transmission. When the Adaptive Modulation Algorithm is disabled, this parameter will serve to determine Fixed Modulation Level used for transmissions. The minimum value for the Maximum Modulation Level is defined by the Sub Band in use. The maximum value for the Maximum Modulation Level is defined by the Sub Band in use and the HW revision of the unit. Units with HW revision A support a maximum value of 7, while units with HW revision B and higher support a maximum value of 8. For information on how to view the Sub Bands supported by the unit and the supported parameters’ values and options, refer to Show Country Dependent Parameters on page 4-9. The default is the highest supported Modulation Level.

Average SNR Memory Factor The Average SNR Memory Factor defines the weight of history (value of last calculated average SNR) in the formula used for calculating the current average SNR for received data frames. This average SNR is used by the ATPC algorithm in the AU and is also included in the Adaptive Modulation Algorithm information messages transmitted by the AU and the SU. The higher the value of this parameter, the higher is the weight of history in the formula. Available values: -1 to 32. -1 is for no weight for history, meaning that average SNR equals the last measured SNR. Default value: 5 Number of HW Retries The Number of HW Retries parameter defines the maximum number of times that an unacknowledged packet is retransmitted. When the Adaptive Modulation Algorithm is disabled, a frame will be dropped when the number of unsuccessful retransmissions reaches this value. For details on the effect of this parameter when the Adaptive Modulation Algorithm is enabled, refer to Adaptive Modulation Algorithm, on page 4-81. The available values range is from 1 to 15. The default value is 10.
Menus and Parameters Manual Revision 1.0 4-81 Burst Mode Burst mode provides an increased throughput by reducing the overhead associated with transmissions in the wireless media. In a burst transmission the inter-frame spacing is reduced and data frames are transmitted without any contention period. The Burst Mode is available only if Burst Mode is supported by the Sub Band in use. For information on how to view the Sub Bands supported by the unit and the supported parameters’ values and options, refer to Show Country Dependent Parameters on page 4-9. In AU, the Burst Mode option will be “blocked” upon trying to enable Burst Mode when the DFS Option is enabled or when using WEP for data encryption. In SU, the Burst Mode option will be “blocked” upon trying to enable when using WEP for data encryption. Burst Mode Option The Burst Mode Option enables or disables the Burst Mode operation. The default is Enable. NOTE When Burst Mode Option is enabled, the SW Retry feature of the Adaptive Modulation Algorithm is disabled. Otherwise it is enabled. Burst Mode Time Interval The Burst Mode Time Interval defines the burst size, which is the time in which data frames are sent immediately without contending for the wireless medium. The range is 1 to the value of the Maximum Burst Duration defined for the Sub Band. The default is 5 milliseconds or the value of Maximum Burst Duration defined for the Sub Band (the lower of the two values). Adaptive Modulation Algorithm (Multi Rate) The Adaptive Modulation Algorithm enables adapting the modulation level of transmitted data to the prevailing conditions of the applicable radio link. The algorithm provides Access Units with simultaneous, adaptive support for multiple Subscriber Units at different modulation levels, as transmission’s modulation level decisions are made separately for each associated SU.
Chapter 4 - Operation and Administration BreezeACCESSS VL System Manual 4-82 Link quality fluctuates due to various environmental conditions. Dynamically switching between the possible modulation levels increases the probability of using the maximum modulation level suitable for the current radio link quality at any given moment. The decisions made by the Adaptive Modulation Algorithm relate to the modulation level selected for transmission of new frames (first trial attempt) as well as the modulation level for retransmissions. The decisions are based on multiple parameters, including information on received signal quality (SNR) that is received periodically from the destination unit, the time that has passed since last transmission to the relevant unit, and the recent history of successful and unsuccessful transmissions/retransmissions. In the AU the decision algorithm is performed separately for each SU. The transmission/retransmission mechanism operates as follows: A. Each new frame (first transmission attempt) will be transmitted at a modulation level selected by the Adaptive Modulation algorithm. B. If first transmission trial has failed, the frame will be retransmitted at the same modulation level up to the maximum number of retransmission attempts defined by the Number of HW Retries parameter. C. If the frame was not acknowledged it frame will be moved to the end of the queue. All other frames in the queue that are intended to the same destination will be moved as well, to preserve the original order. This process is referred to as a Software Retry. D. The frame will be retransmitted at the modulation level selected by the algorithm for the new retrials sequence. Each retrial sequence comprises a number of attempts defined by the Number of HW Retries. E. The process will be repeated up to a maximum number of Software Retries defined by the Number of SW Retries parameter. The Number of SW Retries parameter is not configurable and it is set to the default of 3 SW Retries. (In units upgraded to SW version 2.0 from a lower version it will be set to the previously configured value).. NOTE When Burst Mode Option is enabled, the SW Retry feature of the Adaptive Modulation Algorithm is disabled. Otherwise it is enabled. The Adaptive Modulation Parameters menu includes the following parameters:
Menus and Parameters Manual Revision 1.0 4-83 Adaptive Modulation Option The Adaptive Modulation Option enables or disables the Adaptive Modulation decision algorithm. When enabled, the algorithm supports decrease/increase of transmission’s modulation levels between the lowest possible level to the value configured for the Maximum Modulation Level parameter. If the Maximum Modulation Level is set at the lowest possible level, the Adaptive Modulation algorithm has no effect. The default selection is Enable. Minimum Interval Between Adaptive Modulation Messages The Minimum Interval Between Adaptive Modulation Messages sets the minimum interval between two consecutive adaptive modulation messages, carrying information on the SNR of received signals. The messages in the AU include SNR information on all the SUs associated with it. The available range is from 1 to 3600 seconds. The default is 4 seconds.
Chapter 4 - Operation and Administration BreezeACCESSS VL System Manual 4-84 Service Parameters The Service Parameters menu enables defining user filtering and MIR/CIR parameters. The Service Parameters menu includes the following parameters: ! User Filtering Parameters (SU only) ! MIR and CIR Parameters User Filtering Parameters (SU only) The User Filtering Parameters submenu enables defining the IP addresses of user devices authorized to access the wireless media for security and/or control purposes. In addition, it can be used to enable the transmission and reception of specific protocol frames. These filtering options do not affect management frames sent to or generated by the unit. The User Filtering Parameters menu provides the following options: User Filtering Option The User Filtering Option disables or enables the User Filtering feature. The following options are available: ! Disable, which means no filtering. ! IP Protocol Only, which means only IP Protocol packets pass. ! User Defined Addresses Only, which means only IP frames from/to IP addresses included in the User Filter Addresses list pass. ! PPPoE Protocol Only, which means only PPPoE messages pass (Ethernet type 0x8863 and 0x8864). The default selection is Disable. Set User Filter Address The Set User Filter Address option enables entering up to 8 IP addresses from/to which IP frames are to pass if the User Defined Addresses Only option is selected in the User Filtering Option parameter. The default for all addresses is 0.0.0.0.
Menus and Parameters Manual Revision 1.0 4-85 Set User Filter Mask The Set User Filtering Mask option enables entering subnet masks for each of the User Filter IP Address entries. The default for all subnet masks is 255.255.255.255. Set User Filter Range The Set User Filter Range option enables defining a range of addresses for each of the User Filter IP Address entries. The range includes the base address. Available values range from 0 to 255. The default value is 0 (not used). NOTE Use either a mask or range, but not both, to define a group of user filter addresses. If the range is other than 0, than the mask is ignored. If IP broadcast packets are supposed to reach a device behind an SU unit, the broadcast IP address must be included in the list of user filter addresses. Delete a User Filtering Entry The Delete a User Filtering Entry option enables deleting a selected entry from the User Filtering list. The entry is replaced by the default value. Delete all User Filtering Entries The Delete All User Filtering Entries option enables deleting all entries from the User Filtering list. The list entries are replaced by the default values. Show User Filtering Parameters The Show All User Filtering Parameters option displays the current value of the User Filtering Option and the list of User Filtering addresses, subnet masks and ranges.
Chapter 4 - Operation and Administration BreezeACCESSS VL System Manual 4-86 MIR and CIR Parameters The CIR (Committed Information Rate) specifies the minimum data rate guaranteed to the relevant subscriber. The MIR (Maximum Information Rate) value specifies the maximum data rate available for burst transmissions, provided such bandwidth is available. Under normal conditions, the actual Information Rate (IR) is between the applicable CIR and MIR values, based on the following formula: IR=CIR+K(MIR - CIR). In this formula K is between 0 and 1 and is determined dynamically by the AU according to overall demand in the cell and the prevailing conditions that influence the performance of the wireless link. In some situations the minimum rate (CIR) cannot be provided. This may result from high demand and poor wireless link conditions and/or high demand in over-subscribed cells. When this occurs, the actual information rate is lower than the CIR. The simple solution for managing the information rate in such cases can result in an unfair allocation of resources, as subscribers with a higher CIR actually receive an IR lower than the CIR designated for subscribers in a lower CIR bracket. A special algorithm for graceful degradation is incorporated into the AU, ensuring that the degradation of performance for each individual Subscriber Unit is proportional to its CIR. The MIR/CIR algorithm uses buffers to control the flow of data. To balance the performance over time, a special Burst Duration algorithm is employed to enable higher transmission rates after a period of inactivity. If no data is received from the Ethernet port during the last N seconds, the unit is allowed to transmit N times its CIR value without any delay. For example, after a period of inactivity of 0.5 seconds, a unit with CIR = 64Kbps can transmit up to 64Kbits x 0.5 = 32Kbits without any delay. MIR: Downlink (SU only) Sets the Maximum Information Rate of the downlink from the AU to the SU. The MIR value cannot be lower than the corresponding CIR value. Available values range and default value are shown in Table 4-10 on page 4-87. The actual value will be the entered value rounded to the nearest multiple of 128 (N*128).
Menus and Parameters Manual Revision 1.0 4-87 MIR: Uplink (SU only) Sets the Maximum Information Rate of the up-link from the SU to the AU. The MIR value cannot be lower than the corresponding CIR value. Available values range and default value are shown in Table 4-10 on page 4-87. The actual value will be the entered value rounded to the nearest multiple of 128 (N*128). CIR: Downlink (SU only) Sets the Committed Information Rate of the down-link from the AU to the SU. The CIR value cannot be higher than the corresponding MIR value. Available values range and default value are shown in Table 4-10 on page 4-87. The actual value will be the entered value rounded to the nearest multiple of 128 (N*128). CIR: Uplink (SU only) Sets the Committed Information Rate of the up link from the SU to the AU. The CIR value cannot be higher than the corresponding MIR value. Available values range and default value are shown in Table 4-10 on page 4-87. The actual value will be the entered value rounded to the nearest multiple of 128 (N*128). Table 4-10: MIR and CIR Ranges and Defaults MIR (Uplink and Downlink) CIR (Uplink and Downlink Unit Type Range (Kbps) Default (Kbps) Range (Kbps) Default (Kbps) SU-3 128-2,048 2,048 0-2,048 0 SU-6 128-3,968 3,968 0-3,968 0 SU-54 128-32,896 32,896 0-32,896 0
Chapter 4 - Operation and Administration BreezeACCESSS VL System Manual 4-88 Maximum Burst Duration (SU and AU) Sets the maximum time for accumulating burst transmission rights according to the Burst Duration algorithm. Available values range from 0 to 2000 (milliseconds). The default value is 5 (milliseconds), enabling a maximum burst of (0.005 X CIR) Kbps after a period of inactivity of 5 milliseconds or more. Maximum Delay (SU only) Sets the maximum permitted delay in the buffers system. Since certain applications are very sensitive to delay, if relatively high delays are permitted, these applications may suffer from poor performance due to data accumulation in the buffers from other applications, such as FTP. The Maximum Delay parameter limits the number of available buffers. Data that is delayed more than the permitted maximum delay is discarded. If the SU supports applications that are very sensitive to delay, the value of the Maximum Delay should be decreased. Valid values range from 300 to 10000 (milliseconds). The default value is 5000 (milliseconds). Graceful Degradation Limit (AU only) Sets the limit on using the graceful degradation algorithm. In cases of over demand, the performance of all SUs is degraded proportionally to their CIR (IR=(100%-k%) x CIR). The graceful degradation algorithm is used as long as k ≤K, where K is the Graceful Degradation Limit. Beyond this point the simple “brute force” algorithm is used. The Graceful Degradation Limit should be raised in proportion to the demand in the cell. The higher the expected demand in a cell, the higher the value of the Graceful Degradation Limit. Higher demand can be expected in cases of significant over subscription and/or in deployments where a high number of subscribers are in locations are not enabled for proper communication with the AU at the highest data rate. The available values range from 0 to 70 (%). The default value is 70 (%).
Menus and Parameters Manual Revision 1.0 4-89 MIR Only Option (AU only) When the MIR Only Option is enabled, it forces the MIR/CIR algorithm to use MIR values only. The MIR/CIR algorithm determines the actual information rate for each of the supported SUs under changing conditions of demand, based on the configured CIR and MIR values. When the MIR Only Option is enabled, the MIR/CIR algorithm is overridden and forced to operate with MIR values only. For example, the AU attempts to enable all SUs to transmit/receive information at the specified MIR value. When enabled, the graceful degradation algorithm, which is a part of the CIR/MIR algorithm, is also disabled. The default is Enable. Show MIR/CIR Parameters Displays the current values of the MIR and CIR parameters. Show Service Parameters Displays the current values of the Service Parameters, including the user filtering parameters and MIR and CIR parameters.
Chapter 4 - Operation and Administration BreezeACCESSS VL System Manual 4-90 Security Parameters BreezeACCESS VL can support encryption of authentication messages and/or data frames using one of two encryption standards: ! WEP Wireless Equivalent Privacy algorithm. WEP is defined in the IEEE 802.11 Wireless LAN standard and is based on the RSA’s RC4 encryption algorithm. ! AES Advanced Encryption Standard. AES is defined by the National Institute of Standards and Technology (NIST) and is based on Rijndael block cipher. The following parameters are available through the Security Parameters menu (in certain units some or all of the security options may not be available): ! Authentication Algorithm ! Data Encryption Option ! Security Mode ! Default Key (SU only) ! Default Multicast Key (AU only) ! Key # 1 to Key # 4 ! Promiscuous Authentication (AU only) Authentication Algorithm The Authentication Algorithm option determines the operation mode of the selected unit. The two following options are available: ! Open System: An SU configured to Open System can only associate with an AU also configured to Open System. In this case, the authentication encryption algorithm is not used. ! Shared Key: The authentication messages are encrypted. An SU configured to use a Shared Key can only be authenticated by an AU configured to use a Shared Key, provided the applicable Key (which means both the key number and its content) in the AU is identical to the key selected as the Default Key in the SU. The default is Open System. NOTE
Menus and Parameters Manual Revision 1.0 4-91 NOTE The Shared Key option cannot be selected before at least one Key is defined. In the SU, a Default Key that refers to a valid Key must be selected. The AU and all the SUs it serves should be configured to the same Authentication Algorithm option. Mixed operation is not supported. Data Encryption Option The Data Encryption Option option allows enabling or disabling data encryption. When enabled, all data frames are encrypted. The default is Disable. NOTE The AU and all the SUs it serves should be configured to the same Data Encryption Option. Mixed operation is not supported. Security Mode The Security Mode option enables selecting the algorithm to be used for encrypting the authentication messages and/or data frames. The available options are WEP and AES. The default is WEP. Default Key (SU only): The Default Key defines the Key to be used for encrypting/decrypting the authentication messages (Shared Key mode) and/or data frames (Data Encryption enabled). The AU learns the Default Key from the SU, and it may use different keys when authenticating and/or communicating with different SUs. Available values range from 1 to 4. The default is KEY # 1. Default Multicast Key (AU only): The Multicast Default Key defines the Key to be used for encrypting/decrypting multicasts and broadcasts when Data Encryption is enabled. Available values range from 1 to 4. The default is KEY # 1.
Chapter 4 - Operation and Administration BreezeACCESSS VL System Manual 4-92 Key # 1 to Key # 4 The Key # options enables defining the encryption key to be used for initializing the pseudo-random number generator that forms a part of the encryption/decryption process. The Keys must be set before the Shared Key authentication algorithm or Data Encryption can be used. To support proper operation, both the Key # and the content must be identical at both sides of a wireless link. Each Key is a string of 32 hexadecimal numbers. For security reasons, it is a “write only” parameter, displayed as a string of asterisks (“*”). The default for all 4 Keys is 000…0 (a string of 32 zeros), which means no key. Promiscuous Authentication (AU only) The Promiscuous Authentication mode enables new SUs to join an active cell where Shared Key operation and/or Data Encryption is used, even if this SU does not have the correct security parameters (or if it runs a lower SW version that does not support the security features). After the SU joins the cell it should be remotely configured with the proper parameters (or upgraded). Once the SU is configured properly, the Promiscuous Mode should be disabled. The default is Disable. NOTE Do not leave the AU in the mode of Promiscuous Authentication enabled for prolonged periods. Use it only when absolutely necessary, perform the required actions as quickly as possible and disable it. The unit will return automatically to Promiscuous Authentication disabled mode after reset.

AA Appendix A - Software Version Loading Using TFTP
Appendix A - Software Version Loading Using TFTP BreezeACCESSS VL System Manual A-2 Firmware upgrades to the unit's FLASH memory can be performed by a simple loading procedure using a TFTP application. Before performing an upgrade procedure, be sure you have the correct files and most recent instructions. Upgrade packages can be obtained from the Technical Support section of Alvarion's web site, http://www.alvarion.com/. CAUTION Shutting down power to the unit before completion of the loading procedure may cause the unit to be inoperable. 1. Verify that IP connectivity to the required unit is established. 2. Ensure that the IP address of the PC from which the upgrade is to be performed belongs to the same subnet as the unit to be upgraded, unless the unit is behind a router. If the unit is behind a router, verify that the unit is configured with the correct Default Gateway Address. 3. To view the current IP parameters of the unit, use the Monitor program by connecting the PC to the unit either directly or via Telnet. To access the IP parameters via the Monitor program: A. From the Main Menu select 1 - Info Screens. B. From the Info Screen menu select 2 - Show Basic Configuration. The current basic configuration is displayed, including the run time values for the IP Address, Subnet Mask and Default Gateway Address parameters. 4. To modify any of the IP parameters: A. From the Main Menu, select 3 - Basic Configuration. B. To configure the IP address, select: 1 - IP Address. C. To configure the subnet mask, select 2 - Subnet Mask. D. To configure the default gateway address, select 3 - Default Gateway Address. 5. To verify the connection, PING the unit's IP address and verify that PING replies are being received. To load software versions:
Menus and Parameters Manual Revision 1.0 A-3 6. Use the TFTP utility, with the following syntax, to perform the upgrade: tftp -i hostaddress put sourcefile [destinationfile] where -i is for binary mode and hostaddress is the IP address of the unit to be upgraded. put causes the PC client to send a file to the hostaddress. 7. The original sourcefile name of SW files supplied by Alvarion is in the structure uX_Y_Z.bz, where u is the unit type (a for AU, s for SU) and X.Y.Z is the version number. 8. destinationfile is the name of the file to be loaded. Use the SNMP write community <SnmpWriteCommunity>.bz to define the destination filename. The default SNMP write community is private. For example, to load the upgrade file a1_0_6.bz to an AU whose IP address is 206.25.63.65: tftp -i 206.25.63.65 put a1_0_6.bz private.bz 9. When the loading is complete, the following message is displayed, indicating completion of the TFTP process: Download operation has been completed successfully 10. The unit decompresses the loaded file and checks the integrity of the new version. The new version replaces the previous shadow version only after verification. If verification tests fail, the loaded version will be rejected. Among other things that are tested, the unit will reject a file if either the file name or the version number matches the current Main versions. The unit will also reject a file designated for a different unit type, e.g. an AU upgrade file with the prefix a in the original file name will not be accepted by SUs. 11. The FLASH memory can store two software versions. One version is called Current and the second version is called Shadow. The new version is loaded into the Shadow (backup) FLASH memory. To check that the new firmware was properly downloaded and verified, view the firmware versions stored in the FLASH, as follows: A. From the Main Menu, select 2 - Unit Control. B. From the Unit Control menu, select 5 - Flash Memory Control. C. From the Flash Memory Control menu, select S - Show Flash Versions. The following information is displayed:

BB Appendix B - File Download and Upload Using TFTP
Appendix B - File Download and Upload Using TFTP BreezeACCESSS VL System Manual B-2 The BreezeACCESS VL File Download/Upload feature simplifies the task of remotely configuring a large number of units using TFTP protocol. By downloading the configuration file to a PC it is possible to view all the parameters configured for the unit, as a plain ASCII text file. It is necessary to edit the file using a simple editor and remove certain parameters or change their values prior to uploading the configuration to another unit. The file loading procedure can also be used for uploading a feature license file or an updated country code file to multiple units. When multiple configurations are being done simultaneously, which means that the file is being uploaded to several units, it is recommended that the file will include only the required parameters. In the configuration file, the following three fields represent each parameter: 1. A symbolic string similar to the name of the parameter in the Monitor program, followed by "=". 2. The value of the parameters, which uses the same values as the Monitor program. 3. An optional comment. If used, the comment should start with a ";" character. An unknown parameter will be ignored. A known parameter with a value that is invalid or out of range will be set by the unit to its default value. Use the SNMP write community string (the default is “private”) to define both the uploaded file (put) and the downloaded file (get). The file should be transferred in ASCII mode. Use the extension cfg for a configuration file. Use the extension cmr for the Operator Defaults file. Use the extension fln for a Feature License file. Use the extension ccf for a Country Code file. Feature license and country code files include multiple strings, where each string is applicable only for a certain unit identified by its MAC address. When uploading a feature license or a country code file to multiple units, each unit will accept only the parts that are applicable for itself.
