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 data rates of up to 54Mbps. 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 and Time Division Multiple Access (TDMA) radios. 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 unlicensed BreezeACCESS products

using GFSK modulation, including BreezeACCESS II that operates in the

2.4 GHz band and BreezeACCESS V systems in the 5.7 GHz band.

BreezeACCESS VL products are currently available in the 5 GHz frequency

band, as shown in table Table 2-1.

Table 2-1: BreezeACCESS VL Frequency Bands

Series Frequency Band (GHz)

BreezeACCESS VL 5.4 5.725-5.850

BreezeACCESS VL 5.4 5.470 – 5.725

The actual operating frequencies used by the system can be configured

according to applicable radio regulations and specific deployment

considerations.

Introduction

2-3

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.

BreezeACCESS VL System Manual

2-4

Subscriber Unit

The Subscriber Unit (SU) installed at the customer premises enables the

customer data connection to the Access Unit, providing bridge

functionality and supporting a full LAN.

The Subscriber Unit provides an efficient platform for high speed Internet

and Intranet services. The system delivers fast access to IP-based services

at a data burst rate of up to 54Mbps. 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 SU-A-24-VL Subscriber Unit supports a radio data rate of up to

24 Mbps. The SU-A-54-VL supports a radio data rate of up to 54 Mbps.

The SU-A-24/54-VL Subscriber Unit is comprised of an indoor unit

(SU-NI-VL) and an outdoor unit (SU-RA-VL).

The SU-RA-VL outdoor unit contains the processing and radio modules

and an integrated high-gain flat antenna.

The SU-NI-VL indoor unit 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

Cat.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.

Introduction

2-5

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 various

combinations of modules, including Network Interface (BS-AU) modules for

Access Units operating in any of the bands supported by BreezeACCESS

equipment, including BreezeACCESS VL, BreezeACCESS II and

BreezeACCESS V. It can also accommodate a BS-GU GPS and Alarms

module to support GPS-based synchronization of BreezeACCESS II or

BreezeACCESS V Frequency Hopping radios.

Two different types of power supply modules are available for the

BreezeACCESS VL modules: The BS-PS-DC-VL which 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 BreezeACCESS II or BreezeACCESS V Access Unit

modules, 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 II/V Access Units.

Each BS-AU-VL module, together with its outdoor AU-RD-VL radio unit

and an antenna comprise an AU-D-BS-VL Access Unit that serves a single

sector.

The AU-RD-VL outdoor unit contains the processing and radio modules

and connects to an external antenna using a short RF cable.

Currently available AU antennas include the following:

BreezeACCESS VL System Manual

2-6

Table 2-2: AU Antennas

Antenna Band (GHz) Horizontal Beam width Gain

AU-Ant-5G-16-90 5.725-5.875 90° 16 dB

AU-Ant-5G-15-120 5.725-5.875 120° 15 dB

The BS-AU-VL indoor module connects to the network through a standard

IEEE 802.3 Ethernet 10/100BaseT (RJ 45) interface. The indoor module is

connected to the outdoor unit via a Cat.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.

Standalone “Micro-Cell” Access Unit

The standalone AU-D-NI-VL Access Unit is very similar to the AU-D-BS-VL

unit. The AU-RD-VL outdoor unit and the antenna are the same as in the

AU-D-BS-VL Access Unit. The difference is in the structure of the indoor

part; in the AU-D-NI-VL Access Unit the AU-NI-VL indoor unit is a

standalone desktop or wall-mountable unit rather than a 19” module.

The AU-NI-VL indoor unit 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 Cat.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.

Introduction

2-7

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.

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 VL

The BreezeCONFIG 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 VL utility

to control a large number of units from a single location. In addition,

BreezeCONFIG VL enables you to load an updated configuration file to

multiple units simultaneously, thus radically reducing the time spent on

unit configuration maintenance.

Aligning the Subscriber Unit

Antenna

The RSSI bar display is located on the bottom panel of the outdoor unit.

The ten green RSSI LEDs are used for reading the Received Signal Strength

Indication. The higher the number of green LEDs indicating On, the higher

the level of the received signal. This section describes how to align the

Subscriber Unit antenna using the RSSI bar display.

NOTE:

Antenna alignment using the RSSI 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 RSSI measurement is performed on

received frames, its results are meaningless unless the Subscriber Unit is associated with

an Access Unit.

¾ To align the Subscriber Unit antenna:

1. Align the antenna, which is integrated into the front side of the SU-RA

unit, 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 WLNK orange LED of the unit is On, indicating that the

unit is associated with an Access Unit. If the WLNK LED is Off, check

that the ESSID, Frequency and Security 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 RSSI 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.

6. Secure the unit firmly to the pole.

Commissioning

NOTE:

In some cases, the antenna may need to be tilted to ensure that it is directed toward the

Base Station antenna. For example, if the Subscriber Unit is located very close to the Base

Station.

Configuring the Subscriber

Unit’s Transmit Power Level

and Maximum Data Rate

The following sections describe how to configure the transmit power level

and maximum data rate for Subscriber Units. The Initial Transmit

Power level should be configured only when the Transmit Power Control

Algorithm is disabled.

Configuring the Initial Transmit Power

Level

If the Transmit Power Control Algorithm is enabled you can retain the

default configuration of the Initial Transmit Power parameter, since the

algorithm automatically sets the optimal level of the output power.

If the Transmit Power Control Algorithm is disabled, it is recommended

that the Initial Transmit Power parameter for each SU be set to achieve

an SNR of 26 dB at the AU. Refer to Table 4-2 for the list of optimal

transmit power levels at various distances, assuming a free line of sight

between SU and AU.

550 -1 6000 19.75

600 -0.25 >6000 Pmax (20dBm)

¾ To verify optimal configuration of the initial transmit

power level:

1. If the SU does not associate with the AU, check the configuration of

the ESSID, Frequency and Security parameters. If the parameters

are properly configured, verify the antenna alignment. If the unit is

still not associated with the AU, set the Initial Transmit Power

parameter to its maximum value.

2. After the SU is associated with the AU, check the SNR of the SU at the

applicable AU. For example, you can access the AU’s Monitor program

via Telnet to view the SNR values in the MAC Address Database,

which can be accessed from the Site Survey menu.

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.

BreezeACCESS VL System Manual

4-8

3. If the SNR measurement of the relevant SU at the AU is lower than

26 dB, increase the value of the Initial Transmit Power parameter

for the SU until an SNR measurement of 26 dB is achieved or until the

Initial Transmit Power parameter is set to its maximum value.

Configuring the Maximum Data Rate

This section describes how to configure the maximum data rate for

BreezeACCESS VL Subscriber Units.

¾ To configure the maximum data rate:

1. If, after the SU is configured to its optimal Transmit Power level, the

SNR at the AU is too low, it is recommended that you configure the

Maximum Data Rate parameter to a value that is lower than the

maximum. This can decrease the number of retransmissions due to

attempts to transmit at rates 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 SNR is lower than the values

required for the maximum data rate according to Table 4-3, it is

recommended that you decrease the maximum data rate.

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 Data Rate according to Table 4-3, using the

typical sensitivity 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.

4. Reset the unit to activate the new configuration.

NOTE:

If the unit is associated with the AU, then the final configuration of the Maximum Data

Rate parameter may be performed remotely, for example, from the site of the AU or from

another site.

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 data base for all SUs served by it.

The following sections describe each option of the Site Survey menu.

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 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 unit transmits valid data frames received from the wireless media to

the Ethernet port, as well internally generated frames, such as responses

to management queries and pings received via the Ethernet port. The

Ethernet Counters include the following statistics:

♦ 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.

Operation and Administration

5-19

Wireless Link 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 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 Acknowledge

Time Limit 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 Retransmissions parameter, the frames are 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.

There are also separate counters for the following:

 Beacons (AU only)

 Other Management frames (excluding Beacons in AU)

 Data frames, including multicast/broadcast data frames and

successfully transmitted unicast data frames (excluding

retransmissions).

 Total Transmitted Unicasts, including all 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.

♦ 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 Low, Mid and High

(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.

BreezeACCESS VL System Manual

♦ Total Tx errors: The total number of transmit errors. The following

additional counters are displayed to indicate the reason for the failure:

 Excessive Retries (Exces RTx): The number of dropped frames,

which are the frames unsuccessfully retransmitted until the

maximum permitted number of retransmissions without being

acknowledged.

 Filtered: .

 Underrun: The number of frames that were aborted because the

rate of submitting frames for transmission exceeds the available

transmission capability.

 Other: The number of frames that were not transmitted due to a

problem other than those represented by the other counters.

♦ Total Rx errors: The total number of frames that were not received

properly. The following additional counters are displayed to indicate

the reason for the failure:

 Phy: The number of frames that were not received properly due to a

hardware problem.

 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.

 Other: The number of frames that were not received properly due to

a problem other than those represented by the other counters.

♦ Bad frames received: The number of frames 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.

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.

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 network

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, both the ESSID and Operator ESSID will be included by

the Beacon frames transmitted by it. 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.

NOTE:

The ESSID string is case-sensitive.

Operator ESSID Parameters (AU only)

Frequency Definition Parameters

Frequency Definition Submenu in AU

The Frequency Definition submenu in AU includes a single parameter for

setting the transmit/receive frequency:

Frequency

The Frequency parameter defines the transmit/receive frequency. The

minimum distance between frequencies used by two neighboring AUs is

the Channel bandwidth, which is 20 MHz.

The range and default value depend on the radio band, as shown in Table

5-3. The frequency setting resolution is 5 MHz.

Table 5-3: Frequency Ranges and Defaults

Band Range Default

5.7 GHz 5740 – 5835 MHz 5780 MHz

5.4 MHz 5485 – 5710 MHz 5600 MHz

Frequency Definition Submenu in SU

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.

The Frequency Definition submenu in SU includes the following

parameters:

BreezeACCESS VL System Manual

5-30

Sub Band Lower Frequency

The Sub Band Lower Frequency parameter defines the lowest frequency to

be used during the scanning process.

The range depends on the radio band of the unit, as shown in Table 5-4.

The resolution is 5 MHz.

Table 5-4: Ranges and Defaults for Sub Band Lower Frequency

Band Range Default

5.7 GHz 5740 – 5835 MHz 5740 MHz

5.4 MHz 5485 – 5710 MHz 5485 MHz

Sub Band Upper Frequency

The Sub Band Upper Frequency parameter defines the highest frequency

to be used during the scanning process.

The range depends on the radio band of the unit, as shown in Table 5-5.

The resolution is 5 MHz.

Table 5-5: Ranges and Defaults for Sub Band Upper Frequency

Band Range Default

5.7 GHz 5740 – 5835 MHz 5835 MHz

5.4 MHz 5485 – 5710 MHz 5710 MHz

Scanning Step

The Scanning Step parameter defines the resolution used for selecting

frequencies in the sub band defined by the Sub Band Lower Frequency

and the Sub Band Upper Frequency.

Valid values: 5, 10, 20 MHz.

Default value: 5 MHz.

Frequency Subset Definition

Operation and Administration

5-31

The previous parameters define a sub band of frequencies between the Sub

Band Lower Frequency and the Sub Band Upper Frequency using the

Scanning Step resolution. The Frequency Subset Definition option enables

defining a specific subset of frequencies within this sub band to be used

during scanning. When selected, a list of all valid frequencies in the band

is displayed, and an index is given to each frequency. The current defined

subset is also displayed. The defined subset can be modified by entering a

list of desired indexes, separated by commas (no spaces). Enter A to select

all frequency in the subset.

The default is A, which is the list that includes all indexes of frequencies

defined by the previous parameters.

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 are 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 reachs 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:

BreezeACCESS VL System Manual

5-32

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.

Number Of Scanning Attempts

When the Best AU option is enabled, the SU gathers information on

neighboring AUs for 640 milliseconds 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: 10.

The total scanning time can be calculated based on the following formula:

Scanning Time (secs) = N * F * 0.64

N = Number of scanning attempts.

F = Number of frequencies in the Frequency Subset defined in the

Frequency Definition submenu.

0.64 seconds is the time spent on each frequency while in scanning mode.

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.

Operation and Administration

5-33

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.

♦ 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)

♦ Run Time ESSID (the ESSID of the selected AU)

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 last calculation, the

BreezeACCESS VL System Manual

5-34

lower is 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 the

Current Transmit Power, which is the last value that was previously used

by the ATPC mechanism. If after a certain configurable time the SU did

not succeed to synchronize with the AU, it will start transmitting using the

level configured for the Initial Transmit Power parameter. (If this is the

first time that the SU is powered up, or if the ATPC algorithm was not

used, the Current Transmit Power equals the value of Initial Transmit

Power).

The Initial Transmit Power parameter is used to determine the fixed

transmit power level of the SU if the ATPC algorithm is not enabled.

In an AU typically the maximum supported transmit power is used to

enable 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.

Transmit Power (AU)

The Transmit Power parameter defines the transmit power level of the AU.

This parameter is not part of the ATPC algorithm.

Valid range: 4 to 28 (dBm), using a 1 dBm resolution.

The default is 11 (dBm).

Initial Transmit Power (SU)

The Initial Transmit Power parameter defines the fixed transmit power level

when the ATPC algorithm is disabled. If the ATPC Option is enabled this

parameter serves for setting the initial value to be used by the ATPC

algorithm after the first time of powering-up the unit. It will also be used

by the algorithm as an initial value in the following cases:

a. If the unit does not succeed to associate with the AU after reset.

b. If the unit does not succeed to re-synchronize with the AU after losing

synchronization.

c. If the SU is associated with the AU but there are too many successive

dropped frames, indicating that it transmits at a level that may be too low.

The actual run-time value that is used to control the transmit power level

is determined by the ATPC process.

Operation and Administration

5-35

The allowed range is from -11 to 29 (dBm), using a 1 dBm resolution.

The default value is 4 (dBm).

ATPC Parameters in AU

ATPC Option

The ATPC Option enables or disables the Automatic Transmit Power

Control (ATPC) algorithm.

The default is Enable.

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: 15 to 40 (dB).

Default value: 25 (dB).

Maximum SNR Level

The Maximum SNR Level defines the highest SNR at which you want each

SU to be received at the AU (the higher limit of the optimal reception level

range).

Available values: 15 to 40 (dB).

Default value: 30 (dB).

SNR Memory Factor

The SNR Memory Factor defines the weight of history (value of last

calculated average SNR) in the formula used for calculating the average

SNR. 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

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

BreezeACCESS VL System Manual

5-36

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: 0 to 3600 seconds.

Default value: 120 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: 1-10 (dB)

Default value: 1 (dB)

ATPC Parameters in SU

ATPC Option

The ATPC Option enables or disable 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.

The default is Enable.

Acknowledge Time Out

The Acknowledge Time Out parameter enables augmenting the range of the

system by increasing the time that the unit can wait for a response. This

includes several scenarios where the unit expects a response, such as a

handshake during the association process, an acknowledgement after

transmitting a data frame and CTS after RTS. Increasing the range may

decrease the overall performance and achievable network throughput. It

should be increased only to support ranges of over 10Km. To support a

link distance higher than 10Km, the delay should be increased at both the

applicable SU and the AU.

The Acknowledge Time Out is defined in Clock Cycles, where each Clock

Cycle equals 25 nano-seconds.

The valid range is from 256 (6.4 milliseconds) to 8191(205 milliseconds)

Operation and Administration

5-37

The default is

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 0-512.

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 (see page 5-22). To delete inactive SUs from the database you

must reset the AU.

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 via Telnet, TFTP, SNMP, or ICMP. This excludes

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

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 & Wireless Link

The default selection is From Both Ethernet & Wireless Link.

WARNING:

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.

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

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.

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 enables configuring the following parameters:

VLAN ID-Data (SU only)

The VLAN-ID Data is applicable for Access Links only. 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.

BreezeACCESS VL System Manual

5-42

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) 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.

♦ 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.

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.

WARNING

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’.

NOTES:

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.

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 0-7. 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, is sent to the High queue,

regardless of the priority configuration.

The VLAN Traffic Priority menu provides the following parameters:

VLAN Priority – Data (SU only)

BreezeACCESS VL System Manual

5-48

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.

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.

ToS Priority

The ToS Priority menu enables configuring voice priority parameters to

support end-to-end IPv4 Type of Service (ToS) layer 3 prioritization

according to RFC 791.

The ToS Priority menu includes the following parameter:

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.

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 Broadcasting Filtering menu enables configuring the

following parameters:

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.

♦ From Ethernet Only, which filters broadcast messages received from

including BreezeACCESS VL units.

The available range is 100 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.

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.

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 provides the following parameters:

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.

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, and wait for this number of time slots before accessing the

media, always checking if a different unit has access 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.

Operation and Administration

5-53

The available values are 7, 15, 31, 63, 127, 255, 511 and 1023.

The default value is 15.

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.

Short Frame Multicast Rate (AU only)

The Short Frame Multicast Rate parameter defines the rate of transmitting

multicast and broadcast frames that are shorter than 500 bytes. 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 rate

for broadcast and multicast frame transmissions to increase the

probability that they are received without errors.

The available values for SU-A-54-VL are 6, 9, 12, 18, 24, 36, 48 and 54

Mbps. For SU-A-24-VL the available rates are 6, 9, 12, 18 and 24 Mbps.

The default value is the lowest available rate, 6 Mbps.

Long Frame Multicast Rate (AU only)

The Long Frame Multicast Rate parameter defines the rate of transmitting

multicast and broadcast frames with at least 500 bytes. 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 rate for broadcast

and multicast frame transmissions to increase the probability that they are

received without errors.

The available values for SU-A-54-VL are 6, 9, 12, 18, 24, 36, 48 and 54

Mbps. For SU-A-24-VL the available rates are 6, 9, 12, 18 and 24 Mbps.

The default value is the lowest available rate, 6 Mbps.

BreezeACCESS VL System Manual

5-54

Maximum Data Rate

When the Rate Adaptation Algorithm is enabled, it changes the data rate

dynamically according to link conditions to increase the probability of

using the maximum possible rate at any given moment. Although the

algorithm will avoid using rates that are too high for the prevailing link

conditions, it might be desired under certain conditions to limit the use of

higher rates. If the link quality is not sufficient, it is recommended that

the maximum data rate be decreased, since higher data rate elevates the

error rate. In such conditions, a higher data rate increases the number or

retransmissions before the data rate is being reduced by the Rate

Adaptation Algorithm. A high number of retransmissions reduce 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 data rate of the SU be

decreased in accordance with Table 5-10, 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 Rate Adaptation Algorithm is disabled, this parameter will serve

to determine Fixed Data Rate for transmissions.

Table 5-10: Recommended Maximum Data Rate

For SU-A-54-VL the available rates are 6, 9, 12, 18, 24, 26, 48 and 54

Mbps. The default is 54 Mbps.

Operation and Administration

5-55

For SU-A-24 VL the available rates are 6, 9, 12, 18 and 24 Mbps, and the

default is 24 Mbps.

Number of HW Retries

The Number of HW Retries parameter defines the maximum number of

times that an unacknowledged packet is retransmitted. When the Multi

Rate Support algorithm is disabled, or when the Multi Rate Support

algorithm is enabled but the Software retry Support 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 both the Multi

Rate Support algorithm and the Software Retry Support feature are

enabled, refer to Multi-Rate on page 5-55.

The available values range from 0, which means no retransmissions to 10.

The default value is 4.

Multi-Rate

The Multi Rate algorithm enables to adapt the transmission rate to the

prevailing conditions of the applicable radio link. The algorithm provides

Access Units with simultaneous, adaptive support for multiple Subscriber

Units at different rates, as transmission rate decisions are made separately

for each associated SU.

Link quality fluctuates due to various environmental conditions.

Dynamically switching between the possible transmission rates increases

the probability of using the maximum rate suitable for the current radio

link quality at any given moment.

The decisions made by the Multi Rate algorithm relate to the transmission

rate for new frames (first trial attempt) as well as the rate for

retransmissions. The decisions are based on multiple parameters,

including the RSSI of received acknowledgements from the relevant 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 rate selected by the Multi Rate algorithm.

BreezeACCESS VL System Manual

5-56

b. If first transmission trial has failed, the frame will be

retransmitted at the same rate up to the maximum number of

retransmission attempts defined by the Number of HW Retries

parameter.

c. If the frame was not acknowledged and the Software Retry

Support option is disabled, the frame will be dropped. If the

Software Retry Option is enabled, the 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 rate 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 Multi-Rate Parameters menu includes the following parameters:

Multi-Rate Support

The Multi Rate Support option enables or disables the Multi-Rate decision

algorithm. When enabled, the algorithm supports decrease/increase of

transmission rates between the lowest possible data rate which is 6 Mbps

to the current value of the Maximum Data Rate parameter. If the

Maximum Data Rate is set at 6 Mbps which is the lowest possible data

rate, the Multi Rate Support has no effect.

The default selection is Enable.

Software Retry Support

The Software Retry Support option enables or disables the software retry

mechanism in the Multi Rate algorithm. When enabled, the algorithm

supports decrease/increase of transmission rates between the lowest

possible data rate which is 6 Mbps to the current value of the Maximum

Data Rate parameter. If the Maximum Data Rate is set at 6 Mbps which is

the lowest possible data rate, the Multi Rate Support has no effect.

The default selection is Enable.

Number of SW Retries

The Number of SW Retries parameter enables defines maximum number of

times to use the software retrial mechanism when the Software Retry

Support option is enabled.

Security Parameters

Unauthorized wireless connection is prevented using the Wired Equivalent

Privacy (WEP) algorithm defined in the IEEE 802.11 Wireless LAN

standard. The WEP is based on the RSA’s RC4 encryption algorithm.

The following parameters are available through the Security Parameters

menu:

Authentication Algorithm

The Authentication Algorithm option determines the operation mode of the

selected unit. The two options are Open System and Shared Key:

Open System

An SU configured to Open System can only associate with an AU also

configured to Open System. In this case, the WEP algorithm is not used.

Shared Key

In this mode 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 WEP 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:

The Shared Key option cannot be selected before at least one WEP Key is defined. In the

SU, a Default Key ID that refers to a valid WEP Key must be selected.

Default Key ID (SU only)

The Default Key ID defines the ID of the key to be used for

encrypting/decrypting the authentication messages.

Available values range from 1 to 4.

The default is WEP KEY # 1.

WEP KEY 1 through WEP KEY # 4

These options enable entering the encryption key to be used for initializing

the pseudo-random number generator. Subscriber Units must use the

same WEP Key as the Access Unit.

The WEP Key is a string of 10 hexadecimal numbers.

The default for all 4 keys is a string of 10 zeros, which means no key.

Software Version Loading Using TFTP

A-1

Appendix A

Software Version

Loading Using

TFTP

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, www.alvarion.com.

NOTE:

Shutting down power to the unit before completion of the loading procedure may cause the

unit to be inoperable.

¾ To load software versions:

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.

BreezeACCESS VL System Manual

A-2

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.

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. destinationfile is the name of the file to be loaded.

7. Use the SNMP write community <SnmpWriteCommunity>.dwn to

define the destination filename. The default write community is

private. For example, to load the upgrade file au1_0_6.bz to an AU

whose IP address is 206.25.63.65:

tftp –i 206.25.63.65 put au1_0_6.bz private.dwn

8. When the loading is complete, the following message is displayed:

Download operation has been completed successfully

9. 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, 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:

Appendix B

Configuration

Download and

Upload Using

TFTP

The BreezeACCESS OFDM Configuration 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.

When multiple configurations are being done simultaneously, which means that

the file is being uploaded to several units, it is recommended that the file only

include the required parameters.

In the configuration file, each parameter is represented by three fields:

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). Use the extension cfg for a

configuration file. Use the extension cmr for the Operator Defaults file. The file

should be transferred in ASCII mode.

For Example:

To upload the configuration file using a DOS based TFTP Client to an SU whose IP

address is 206.25.63.65, enter:

tftp 206.25.63.65 put Suconf private.cfg

To download the Operator Defaults file from the same unit, enter:

tftp 206.25.63.65 get private.cmr Suconf

conveniently route the cable into the waterproof seal off the Outdoor unit

and through holes in walls.

Figure C-1 shows the wire pair connections required for the Indoor-to-

Outdoor cable.

Figure C-1: Ethernet Connector Pin Assignments

Use a crimp tool for RJ-45 connectors to prepare the wires, insert them

into the appropriate pins and use the crimp tool to crimp the connector.

Make sure to do the following:

1. Remove as small a length as possible of the external jacket. Verify

that the external jacket is well inside the service box to ensure

good sealing.

2. Take back the shield drain wire before inserting the cable into the

RJ-45 connector, to ensure a good connection with the connector’s

shield after crimping.
