Publication History Revision Date Description Rev 1 APR 2002 Initial release of manual. APR 2002 Rev 03 xi Notices xii AWE 120-58 User Guide Description Features The AWE 120-58 advanced wireless Ethernet bridge provides high-speed, wireless connectivity at a fraction of the cost of wired solutions. It operates over the 5.7250 – 5.8500 GHz ISM radio band and has a maximum raw wireless data rate of 12 Mbps. • Provides wireless connectivity at speeds up to eight times faster than regular T1 lines, making the AWE 120-58 ideal for providing high-speed Ethernet access or for wirelessly extending existing communications infrastructures. • Supports point-to-point, point-to-multipoint, and multipoint-to-multipoint networks (if all remotes have clear line of sight to the base station and to each other). Contentionless polling ensures efficient access to remote data networks. • Is self-contained and easy to use. Simply connect an AWE unit to each LAN segment, and the unit automatically learns where nodes are located on the network and performs dynamic packet filtering to ensure the local LAN traffic does not overload the wireless connection. • Uses Wi-LAN's patented Multi-Code Direct Sequence Spread Spectrum (MC-DSSS) technology, which makes the unit spectrally efficient and resistant to interference. MC-DSSS technology increases data throughput by as much as ten times compared to traditional spread spectrum technology. • Other features include automatic Tx power level adjustment, IP address filtering, throughput throttling and monitoring, high security and reliability, and a flash-code upgrade path. SNMP, telnet and RS-232 management enable users to manage, configure and monitor their wireless network with ease. • VLAN compliant—supports transparent forwarding of VLAN-tagged frames (increased frame size supported) and remote management of units within a VLAN environment (i.e. units connected via trunk links). Supports VLAN tag insertion/removal and VLAN supporting protocols (802.1D, 802.1P, GVRP). About Spread Spectrum Three frequency bands (called the ISM bands) are allocated in Canada and the United States to a radio technique known as spread spectrum communication. The bands are located at 900MHz, 2.4 GHz, and 5.8 GHz (shown in the following illustration). The AWE 120-58 operates with spread spectrum technology over the 5.7250 – 5.850 GHz band. APR 2002 Rev 03 Description License-Free ISM Bands 26 MHz Wide 900 MHz 902 MHz 928 MHz 83.5 MHz Wide 2.4 GHz 2.4 GHz 2.4835 GHz 125 MHz Wide 5.8 GHz 5.725 GHz 5.85 GHz Direct Sequence Spread Spectrum (DSSS) technology converts a data stream into packets and spreads the packets across a broad portion of the RF band. The particular spread pattern depends upon a code. With multi-code DSSS (MC-DSSS), multiple codes and spread patterns are employed. A spread spectrum receiver reconstructs the signal and interprets the data. Some advantages of DSSS are as follows: • Resistant to interference: DSSS overcomes medium levels of interference and multipath problems. • Security: There must be a decoder at the receiving end to recover data (an AWE can only talk to another AWE). Data is transmitted at irregular time intervals. • Low probability of detection: Due to a low amplitude signal and wide bandwidth. • No license fee: A license fee is not required if used in the specified radio bands and the transmitter power is limited. About AWE Units AWE 120-58 units can function as base stations, remote units or repeater bases. Base Station: One unit in your wireless network must be a base station. A base station acts as the central control unit of the wireless network.The base station polls all remote units and controls how traffic is routed to and from remotes.The base usually connects to a major access point of the wired network.The antenna of the base station must be capable of transmitting and receiving radio signals to and from all the remote units in a system. If remotes are spread over a large area, an omni-directional antenna is usually required. See Configuring a Base Station , page 15 for information about setting up a base station. AWE 120-58 User Guide Some System Applications Remote Units: Remote units receive and transmit wireless data to the base station.You need at least one remote unit for each wireless link. Remotes can limit the amount of data passed by the remote (a function called throttling), and they can filter data packets based on their IP address. If remote units communicate only with the base station, their antennas can be more directional and have higher gains than base antennas. See Configuring a Remote Unit , page 18 for information about setting up a remote unit. Repeater Base: A base station can be configured as a repeater base. A repeater is needed when remote units cannot communicate directly with each other, but direct transfers of data between them are necessary (as in a true WAN). When configured as a repeater, the base station passes data packets between remote stations based on the remote group status and a list of MAC (Media Access Control) addresses that the base station automatically builds. A single repeater uses a method called “store and forward” to receive data from the originating remote and to pass data to the destination remote. See Setting a Base to Repeater Mode (Base Station Only) , page 102 for more information. Two units can also be employed as a dual unit repeater (back-to-back) configuration that maximizes data throughput. Some System Applications You can build a wireless network from AWE units and various other components such as cables and antennas. The following section shows some simple examples of AWE applications. Making a Simple Wireless Bridge The simplest example of using a AWE 120-58 is a point-to-point wireless bridge that connects two wired network segments or LANs. Two AWE units are required: a base station and a remote unit. Point-to-Point Wireless Bridge Wireless Link Main Wired Network Wired Network Router Switch Hub Firewall Remote Base Router Hub Switch Firewall Creating a Simple Wireless Network You can create a point-to-multipoint wireless network by adding several remote units to a base station. A base station can support up to 1000 remotes, however,Wi-LAN recommends no more than 225 remotes per base station to ensure high levels of data throughput. See Determine the Number of Remotes , page 135 for more information. APR 2002 Rev 03 Description Point-to-Multipoint Wireless Network Wired Network Router Switch Hub Firewall Remote Wireless Links Main Wired Network Wired Network Router Switch Hub Firewall Base Remote Router Hub Switch Firewall Base station polls Remote Units Wired Network Router Hub Switch Firewall Remote Direct remote-to-remote communication can occur if a direct RF link can be established between remotes, and if remotes are in the same RF group. Remote-to-Remote Communication Remote Wireless Links Main Wired Network Base Remote Remotes must be in the same RF group to communicate directly Remote AWE 120-58 User Guide Some System Applications Creating a Network with Cells Cells or data nodes can be created with AWE units to maximize coverage, minimize interference, and increase data throughput. Directional antennas are mounted on a mast to divide cells into sectors.Each sector is connected to an antenna and a base station. Directional antennas increase signal gain within the sector and increase the distance possible between base stations and remotes. Center frequency, acquisition code and antenna polarization techniques are used to isolate sectors. The increase in data rate depends on the number of sectors. For example, the data rate of Cell 1 in the diagram below is 36 Mbps (12 Mbps x 3 sectors). Cells are distributed across a service area and can be linked to each other via a wireless link or a fiber optic cable. Implementing a network with cells requires comprehensive network planning and site preparation. Please contact Wi-LAN for information about creating a network with cells.

The repeater passes data around the obstacle to any remote in the same RF group. The single unit repeater slows data throughput due to the “store and forward” process where each packet is handled twice. A dual unit repeater does not slow data throughput.

Establishing a Basic RF Link This test ensures that a basic RF link exists between a base station and a remote unit. Important The quality of your digital data transmission depends greatly on the quality of your RF link. Always try to establish a high-quality RF link first. A high-quality RF link will result in high-quality data transmissions and a low BER. A low-quality RF link will result in low-quality data transmissions and a high bit error rate (BER). Digital data can always be sent across a high-quality RF link. If the RF link is of poor quality, data either cannot be sent at all or will contain too many errors to be useful. Tip: First configure one unit as a base station, and then use it to test all the remote units. ➧ To establish a basic RF link 1. Ensure that one unit is configured to a base station, select a center frequency and set the test minutes. See Configuring a Base Station , page 15. 2. Ensure that the other unit(s) are configured as remote units with the center frequency the same as the base station. See Configuring a Remote Unit , page 18. 3. Place the base station and a remote unit at least two meters apart with a clear line of sight between antennas. Point the antennas toward each other. 20 AWE 120-58 User Guide 4 Bench Test Units Basic Test Setup Indoor Antenna Indoor Antenna 2m minimum Coax Adapter Cable Coax Adapter Cable Base Unit Remote Unit 4.

Power up both AWE units. The power LEDs on both the base station and remote unit Power Inserter Units should be GREEN. 4. Configure the AWE units within your network. See Network Configuration , page 40 for information about AWE Internet addresses. See Appendix C: Configuring a Simple Data Network , page 151 for information about configuring simple peer-to-peer networks. 5. Create some network traffic to test the wireless link. For example, use ping or ftp put and get to transfer large test files, in both directions, across the link. When the file transfer is done, ftp displays the size of the file and the time it took to transfer the file. This information can be used to measure the data throughput of the wireless link, and is very useful for troubleshooting. 24 AWE 120-58 User Guide 4 Bench Test Units Using ping and ftp ping From the command line prompt, type: C:> ping IP Address Example: ping 192.163.2.88 ftp To connect to the node, from the DOS prompt, type: C:> ftp IP Address For instructions about using ftp, type “help” at the ftp prompt. ftp> help Follow the instructions. 6. Test all units in the network. APR 2002 Rev 03 25 Installation 5 Install Units This section provides some guidelines about installing units in the field. WARNING All antennas must be professionally installed following accepted safety, grounding, electrical, and civil engineering standards. ! CAUTION Never operate a unit without an antenna, dummy load, or terminator connected to the antenna port. Operating a unit without an antenna, dummy load, or terminator connected to the antenna port can permanently damage a unit. • Install the units at locations identified in the network plan. • Verify that there is no interference at the site by performing spectrum sweeps with a spectrum analyzer. Perform sweeps at various times of the day (for example, 9AM, noon, and 3 PM are peak telephone traffic times.) If there are problems, contact the network planner, who may need to change the system configuration or design. • If test equipment is available, sweep antennas and cables with the Site Master ® communications test set before securing antennas and cables to towers, while they are on the ground and easy to access. Sweeping helps to ensure that antennas and cables will operate as expected. • Initially install equipment with flexibility—do not tie down cables, antennas should be free to move, allow some slack in cables, avoid drilling and do not seal connections. • Align antennas*. (Two people are required, one at the base station and one at the remote unit. When in the field, you may require binoculars and 2-way radios to communicate.) When aligning antennas, adjust the orientation of the remote antenna while running a link monitor test between the remote and the base station. Adjust the antenna until you achieve the highest fade margin with no bit errors (BER = 0). See Performing Link Monitor Test (Normal Mode) , page 72 for instructions. Repeat the antenna alignment procedure for each remote. • When antennas are aligned and cables are secured, sweep the antennas with the Site Master test set a final time before connecting to AWE. • Perform diagnostic tests on the installed system. Compare field results to bench test results using ping, ftp, fade margins, etc. Document your results (these results will be very useful when troubleshooting and monitoring the system’s performance). • When the system works as specified, lock down and weatherproof all equipment and connections. * The antenna(s) used for this transmitter must be fixed-mounted on outdoor permanent structures with a separation distance of at least 2 metres from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter. 26 AWE 120-58 User Guide 6 Test Network Point-to-Multipoint Installation The procedure for installing a point-to-multipoint system is the same as the procedure for installing a pointto-point system. Treat each link in a point-to-multipoint system as a single, point-to-point wireless link. Co-Location Installation When you install a system with sectors and co-located base stations (see Creating a Network with Cells page 5 for an example), you install and test sectors as if they were point-to-point systems; however, in this case you must ensure that individual sectors are not interfering with each other. Please contact Wi-LAN for information about planning and installing co-located units. • Align and test the first sector. Measure the fade margin and run the link monitor test. Document your results, then turn off the radio in the first sector. • Align and test the second sector. Measure the fade margin and run the link monitor test. Leave the link monitor test running in the second sector. • Turn on the radio in the first sector again and run the continuous transmit test. See Performing Transmit and Receive Tests , page 75. • Observe the BER and fade margin of the second sector radio. Look for changes to determine if the first sector is interfering with the second sector. • Repeat the tests for all sector/pair combinations. 6 Test Network Run the link monitor test and other tests such as ping and ftp file transfers to verify network operation when the units are installed in the field. See Performing Link Monitor Test (Normal Mode) , page 72. Adding to a Network Always add to your network one link or device at a time, working from a known base network. Measure and document changes to the system and changes in performance. For example, you can transfer files with ftp and measure the performance with LAN analyzer software. The key to a successful network is to proceed one step at a time and to understand your network! APR 2002 Rev 03 27 Installation Network Test Setup Indoor Antenna Indoor Antenna Base Unit Remote Unit Power Inserter Unit To radio To LAN PC LAN 10/100 BaseT HUB PC with LAN analyzer software Preventative Maintenance and Monitoring You should set up a preventative maintenance schedule for your network. Wi-LAN recommends that the following preventative maintenance be performed at least semi-annually. • Regularly run link monitor tests across the network and measure BER and fade margin.You can also test the network with ping, ftp and file transfers. Other resources are available on the Internet that can help you monitor the performance of your link. • If you have SNMP application software, you can check unit operation from a remote location. See Appendix D: SNMP , page 157 for more information. If you have SNMP application software, you can check unit operation remotely. See Appendix D: SNMP page 157 for more information. You should periodically perform a physical inspection of each site. • Check that antennas and cables are secure and have not become loose. • Check for physical obstructions in the line-of-sight radio path, such as trees and buildings. • Sweep antennas and cables to ensure that antennas and cables are intact and operating properly. • Check that there are no water leaks in cabinets. • Check weatherproofing. • Check for new sources of electromagnetic interference. 28 AWE 120-58 User Guide Configuration Overview This section explains how to use the Main Menu to configure and test your AWE unit, and to obtain useful statistical and maintenance information.

If IP Address Filtering is on, this item specifies the action to take when either no filter entry applies or where there is a conflict between filters. Filter Entry n= 1–8 Entry number of the filter. Up to eight filters can be created. Range n = 0–255 Defines how many contiguous IP addresses are in the filter’s list of addresses Base Address n = lowest IP Address Lowest numbered address on the filter’s list of IP addresses State Pass Block Disabled Shows state of an individual filter. “Pass” allows packets to pass. “Block” stops packets from passing. “Disabled” enables you to make a particular filter inactive. IP Packet Filtering IP Address Filtering Two different IP filters are available: a packet filter, and an address filter. The IP packet filter determines which type of packets are allowed to pass through a unit. If the IP Packet Filter is OFF, the unit passes all packets. If the IP Packet Filter is ON, the unit passes only IP and ARP (Address Resolution Protocol) packets. IP address filters are actually tables that contain lists of IP addresses. Data packets are either passed or blocked depending on whether the packet IP address is listed in the table, the setting of “Default IP Address Filtering” (pass or block), and the “State” setting of each filter. Air IP Address Filter Table xxx.xx.xx.x xxx.xx.xx.x IP xxx.xx.xx.x Addresses Wire Data packets are blocked or passed depending on whether the packet address is listed in the IF filter table and other filter settings Each IP address filter is defined by a range and a base value. IP address filtering improves system security and helps manage data throughput. APR 2002 Rev 03 45 Configuration Viewing IP Filter Configuration ➧ To view current IP filter configuration Two sample configurations below show how IP address-filtering works. Example 1: H - Help IP Filter Configuration IP Packet Filtering IP Address Filtering Default IP Address Filtering -> off on Pass Filter Entry ------------------- Range (0-255) ------------------- Base Address State ------------------------------------- 100 192.168.1.1 Block 10 192.168.1.51 Pass Filter 1 blocks all packets containing a LAN-side IP address in the range 192.168.1.1 to 192.168.1.100 inclusive. Filter 2 passes all packets containing a LAN-side IP address in the range 192.168.1.51 to 192.168.1.60. Note that this range partially overlaps the range of Filter 1, resulting in a conflict between filters. When a conflict occurs, the action specified by Default IP Address Filtering takes precedent, which is “Pass”. Therefore all packets with IP addresses that “overlap” will be passed. All packets containing a LAN-side IP addresses not within either filter range are subject to the action specified by Default IP Address Filtering (passed).

Filter 1 passes all packets containing a LAN-side IP address in the range 192.168.1.1 - 192.168.1.50 (except for those IP addresses in the range specified in Filter 2). Filter 2 blocks all packets with a LAN-side IP address in the range of 192.168.1.21 - 192.168.1.30, Filter 3 passes all packets containing a LAN-side IP address in the range 192.168.1.101 - 192.168.1.110 (except for those IP addresses in the range specified in Filter Entry 4). Filter 4 blocks all packets with a LAN-side IP address in the range of 192.168.1.105 – 192.168.1.106. Filter 5 is disabled (not used). All packets containing a LAN-side IP address for which no filter entry applies will be blocked. Note: LAN-side IP address—If a packet arrives at the RF port, the LAN-side IP address is the destination IP address contained within the packet. If a packet arrives on the Ethernet port, the LAN-side IP address is the source IP address contained within the packet.

The VLAN Registration table is used to define the sets of VLANs that can be reached (or alternatively cannot be reached) through individual ports of the unit. It is referenced by the following processes: 1. Ingress/Egress Filtering: If Ingress (Egress) filtering is enabled, the Registration Table is referenced to determine whether a packet is processed or filtered on reception (transmission) based on the registration status of the VLAN associated with it on the inbound (outbound) port. 2. Packet Forwarding on Hybrid Links: For hybrid links, the Registration Table determines for each outbound packet whether VLAN tagging information is included with the packet, based on the destination VLAN for the packet. 3. GARP VLAN Registration Protocol (GVRP): If GVRP is enabled, the Registration Table is referenced to determine the registration status for a particular VLAN on each port.

Similarly, all other participants broadcast their parameters to this unit. Based on this unit’s parameters and those received by other bridges, the network topology is created, possibly with some ports on some devices (maybe one on this unit) being disabled to prevent the occurrence of broadcast loops If a change in topology is detected by any device, a notification message is broadcasted and the network, if required, is re configured. This feature is particularly useful for critical links in which redundant paths exist. If one link should go down, a change in topology is detected and a second “backup” link is brought online.

Throttling restricts the flow of data from air to wire or from wire to air. When throttling is enabled, the amount of data passed is equal to the throttling level times 64 kbps, to a maximum of 6.4 Mbps. Throttling applies to both down link and up link traffic, so a throttle level of 1 means the unit will pass 64 kbps in each direction. A throttle level of 100 means that 100 x 64 kbps will be passed.When throttling is disabled, the unit uses the maximum available bandwidth.

Three different modes are available: off mode is selected to run Link Monitor in the usual manner (where Link Monitor tests the link and collects statistical information). Automatic Output Power mode tests the link (with Link Monitor) and automatically adjusts Tx power up or down based on measurements taken when the mode is selected. Dynamic Output Power mode runs Link Monitor in the background and periodically adjusts Tx power in response to the current radio conditions and environment. The amount of bandwidth (test overhead) used for all modes is set with Link Monitor Period . (See Setting the Link Monitor Period page 78). How Automatic Output Power Adjustment Works Link Monitor tests a link by sending test packets and measuring the link’s performance (in terms of BER and power). The results of the test can be used to automatically adjust Tx power. Automatic power level adjustment is explained below. The maximum Tx power output (factory-set power ceiling ) of a unit is set at factory and cannot be changed with configuration menus (for more information see Viewing Unit Identification , page 35). A user-specified power ceiling or limit can be set by the user using User Output Power Adjust Ceiling on the RF Station Configuration screen.The user-specified ceiling is the maximum Tx power level with which the user allows the unit to operate. Factory-set Power Ceiling User-specified Power Ceiling Power Level Automatic power adjustment moves power level up and down Operating Tx Power Level (Base Tx Power Level + Signal Margin) Signal Power Signal Margin Base Tx PowerLevel Noise Floor The noise floor is the power level below which signal quality deteriorates rapidly due to random radio interference causing the link to not function properly. Base Tx Power level is the starting power level or "base" from which the adjustment is made. The operating Tx Power level is the sum of the base power level and the signal margin (fade margin)—the signal margin is added to the Tx base power level and moves with it. Both the base power level and the signal margin can be adjusted to reach the operating power level, When a unit adjusts the power level, it begins at the base power level and runs Link Monitor. If no bit errors occur and the power level is satisfactory, the unit automatically drops the Tx power level by one dB and runs Link Monitor again. If no bit errors occur again and power level is adequate, it once again drops the Tx power APR 2002 Rev 03 83 Configuration level by one dB and runs Link Monitor. This process repeats until a power level occurs where no bit errors occur and power level is lowest. This level is the minimum power level required for operation and is displayed numerically by Current Output Power Level Adjust on the screen. When the unit reaches this level, Tx Power (seen on the Radio Module Configuration screen) is automatically reset to the new level. (Below this level, BER and power levels are unsatisfactory for data communication) . If the intitial base Tx power level is below the noise floor, a unit will automatically increment the power level by one dB until the BER and power level become satisfactory. In short, two modes of automatic power level adjustment are available: automatic and dynamic. Automatic Output Power mode: Power is monitored and automatically adjusted once when the automatic output power mode is activated. The resulting output power value is saved and Output Power Control Mode automatically returns to “off”. Dynamic Output Power mode: Power is monitored and automatically adjusted periodically during regular operation. Some bandwidth for data is lost due to test packet overhead—the amount of overhead is determined by setting the Link Monitor Period (see Setting the Link Monitor Period , page 78). Dynamic Output Power mode is not recommended in co-location situations. Note: A unit will adjust the power output to compensate for noise problems, however if the noise floor is too high the unit will not be able to establish an RF link. In this case, an RF spectrum analysis should be performed to determine the cause of the problem. Tx Power Adjust on the Radio Module Configuration screen is used to set the initial or base Tx power level. After the level is set automatically, this value is automatically reset by the unit. The reset value can be read by viewing Current Output Power Level Adjust on the RF Station Configuration screen, or by viewing Tx Power Level Adjust on the Radio Module Configuration screen. 84 AWE 120-58 User Guide RF Station Configuration ➧ To set the output power mode 1.

For a remote unit, rank is a unique polling ID number that identifies a remote to a base station. When it polls remotes, the base station begins polling at the remote with rank number 1, then proceeds to the remote with rank number 2, then goes to the remote with rank number 3, and so on. The base continues polling remotes until it reaches the remote with the highest rank number. The base then repeats the polling cycle.

The AWE 120-58 can operate at a center frequency ranging from 5.7410 GHz to 5.8338 GHz, in 400 kHz steps. All units in the same system must be set to the same center frequency. If you plan to co-locate AWE 120-58 systems, you will need to use more than one center frequency.You will choose center frequencies that are well-separated from each other. The following section Choosing Center Frequencies explains how to choose center frequencies. Choosing Center Frequencies A simplified diagram of the spectrum around a center frequency (when transmitting) is shown below. Center Frequency Spectrum 66 MHz 16 MHz 33 MHz 16 MHz Data Region Side Lobe Side Lobe 5.7410 GHz 5.8338 GHz Center Frequency Only the 33 MHz data region of the 66 MHz spectrum contains data; the remaining 16 MHz side lobes contain no useful information (frequency ranges given are approximate).The side lobes operate at a much lower power than the data region. If only one center frequency is required, simply choose a frequency between 5.7410 GHz and 5.8338 GHz (in 400 kHz increments).You will probably choose a center frequency where the 5.8 GHz ISM band is cleanest, meaning a frequency where no other people are transmitting. If two or more AWE 120-58 systems must be co-located, center frequencies are selected that have as much separation as possible so different systems do not interfere with each other. It is very important that the 33 MHz data regions of adjacent systems do not overlap. System performance is also better if the side lobes of one system do not overlap the data region of another system. It does not matter if the side-lobes of two systems overlap. APR 2002 Rev 03 95 Configuration Some examples of center frequency separation and performance ratings are provided below. Excellent Good Fair Poor These examples show that there is no benefit to separating the center frequencies of adjacent systems by more than 66 MHz. 48 MHz of center frequency separation is more than adequate in most cases. Separation of 33MHz is adequate for strong RF links, but weak signals will be degraded by the overlap of the side-lobes into the data region. Overlapping of data regions is not recommended and will cause problems. The following diagram shows seven different center frequencies in the 5.8 GHz ISM band that are spaced as far apart as possible.You can choose your center frequencies from these sample schemes. Sample Center Frequency Schemes for Co-located Systems 1 System Choose any one center frequency 2 Systems Choose two center frequencies 3 Systems 4 Systems 5.8500 5.8338 5.8182 5.7803 5.7874 5.7718 5.7562 5.7410 5.7250 Center Frequency (GHz) For best performance, choose center frequencies that are separated as much as possible and nonoverlapping. Three co-located system could use the A,D and G center frequencies. Frequencies B, D and F would probably work equally as well. Four co-located systems could use the A, C, E and G frequencies. Having more than four co-located systems would require careful radio network planning to ensure the proper operation of each system. 96 AWE 120-58 User Guide Radio Module Configuration ➧ To set the center frequency 1.

APR 2002 Rev 03 101 Configuration Setting a Base to Repeater Mode (Base Station Only) When repeater mode is enabled at a base station (Repeater Mode = on), the base acts as a repeater in addition to performing its normal base station functions. As a repeater, the base station receives incoming messages from remotes, stores them and broadcasts them to all remotes within RF range. Remotes belonging to the same RF group (with the same RF Group number) can communicate via the repeater. (See Setting Remote Unit RF Group , page 106 for information about RF groups.) The diagram below explains the process. Repeater Mode Message is sent from originating remote Wired Network Wired Network Remote RF Group n n = 1–63 Rank = 1 (ID # of remote) Remote Message is stored and broadcast to all remotes in RF Group n RF Group n n = 1– 63 Rank = 3 (ID # of remote) Base Wired Network Remote RF Group n n = 1– 63 Rank = 2 (ID # of remote) Repeater Mode = on Rank = 4 (number of remote units) Message is received by destination remote Wired Network Remote RF Group n n = 1– 63 Rank = 4 (ID # of remote) When repeater mode is disabled (Repeater Mode = off), the base station functions normally (it polls remotes and links the various segments of the network). By definition, Repeater Mode does not apply to units of RF Group = 0. 102 AWE 120-58 User Guide Radio Module Configuration ➧ To set base to repeater mode 1.

A base station automatically learns which remote stations are active and which are idle. The base station waits a brief time period for a remote to respond to a poll.The remote either does not respond to the poll, or it responds with a negative acknowledgement. The base then considers the remote to be idle. (This process is called dynamic time allocation or DTA.) Idle remote units are ignored by the base station for the number of polling rounds entered in the Dynamic Polling Level field. The higher the dynamic polling level, the more efficient the throughput and the longer it takes to move a subscriber from an inactive state to an active state. Dynamic Polling improves system performance whenever there is more than one remote. When there are a large number of remotes system performance improves significantly. Note: Polling level is set only at the base station. ➧ To set the dynamic polling level 1. From the Main Menu, select RF Station Configuration and press Enter.

APR 2002 Rev 03 105 Configuration Setting Remote Unit RF Group The RF Group setting enables you to determine which units in a system can communicate with each other. For example, in a system consisting of a base station and associated remotes, you can: 1) assign units to different groups so that only members of the same group can communicate with each other and the base (an open system); 2) isolate remotes so they cannot talk to other remotes, but can talk only to the base (a closed system); 3) assign remote units to groups and configure the base station as a repeater (a closed system); and 4) combine closed units with open units in the same system. These configurations are explained below. Remote units with the same RF group number (RF Group = 1– 63) can communicate directly with each other and with the base station (if there is a line-of-sight RF path between units and base station Repeater Mode = off.) An example is a company where the Human Resources department needs direct access to the Payroll department, but the two departments must be isolated from other departments. Since HR and Payroll are in the same RF group 14, they can talk directly to each other, but they cannot talk directly to other groups such as R&D, which belongs to RF Group 20. Example 1: Open System Repeater Mode = off Base Remote RF Group = 20 R&D Remote RF Group = n n = 1 – 63 RF Group = 14 Human Resources Remote RF Group = 14 Payroll Remote units configured as RF Group = 0 are independent, closed units. Closed units cannot talk directly to each other, they can only talk directly to the base station. This setup acts to isolate remote units and the associated LANs from each other. Example 2 shows a situation where independent companies are connected wirelessly to a single base station and communication between the companies is prevented. Example 2: Closed System Repeater Mode = off Base Remote Remote RF Group = 0 Company 1 RF Group = 0 Remote Company 3 RF Group = 0 Company 2 106 RF Group = 0 AWE 120-58 User Guide Radio Module Configuration A repeater is used to bypass obstacles that block the RF path (for example, a mountain). When a base station is set to repeater mode (Repeater Mode = on), it can pass data from remotes in an RF group to other remotes in the same group. A system with a repeater is a closed system. Example 3 shows a repeater with four remotes. All the remotes are in the same RF Group 4, so they can talk to each other via the repeater base. Example 3: Repeater Configuration (Closed System) Repeater Mode = on Base Closed System Remote Remote RF Group = 4 n = 1 – 63 RF Group = 4 n = 1 – 63 Mountain Remote Remote RF Group = 4 n = 1 – 63 RF Group = 4 n = 1 – 63 No direct communcation possible due to obstacle Closed remote units (RF Group = 0) can be combined with open remote units (RF Group = non-zero) within the same system. In this case each group in the system behaves according to its RF Group characteristics: closed remotes could communicate only with the base, remotes with the same (non-zero) group number could communicate with each other, and remotes with different (non-zero) group numbers could not communicate with each other. A base or repeater would not pass packets originating from a closed remote. The following table summarizes the first three situations. Repeater Mode (Base only) RF Group (Remote only) System Type System Characteristics Repeater Mode = off 1–63 Open Remotes can communicate directly with the base and each other if remotes that have the same non-zero RF group number (if a LOS RF path can be established) Repeater Mode = off Closed Remotes can communicate only with the base station—they cannot talk to each other Repeater Mode = on 1–63 Open Remotes cannot communicate directly with each other, they can only communicate via the repeater base with other remotes that have the same RF group number In a mixed system, each RF group behaves according to the RF Group characteristics assigned to it (0 = closed, 1–63 = open; same non-zero group number = communication, different non-zero group number = no communication).

Wi-LAN recommends the following practices. • Maintain the integrity of the system design when adding or changing a system. The introduction of new elements to a system can cause problems unless the network plan is revised to take into account the changes. For example, improper installation of a co-located antenna can add unwanted system interference. • Measure and document system performance at the time of the original installation. • Monitor system performance regularly. Environmental change as well as normal wear and tear on components can affect system performance. • Perform preventative maintenance every 6 months. See Preventative Maintenance and Monitoring , page 28 for information. • After periods of extreme weather, perform link monitor tests to verify the system; inspect towers, antennas, cables and connectors for damage. • Change menu passwords so that only key personnel can reconfigure the system. See Setting Menu Passwords , page 117. • Keep records of recent changes. Especially document the addition of units, hardware and software changes and changes to configuration settings. Configuration errors often cause other problems. Current records can be compared with original installation records and function as a benchmark to help you troubleshoot. • Keep a log of past and present problems and solutions. Store the log on-site, if possible. The log identifies common failure points and fixes. • Before contacting Wi-LAN for customer support, document the symptoms of the problem and the steps taken to diagnose and fix the problem. Record the current configuration of the system. APR 2002 Rev 03 129 Troubleshooting Troubleshooting Areas There are five key areas to be aware of when troubleshooting. Network Integrity: Continued performance and reliability of a network depends upon maintaining the integrity of the network. If you change a network’s design, you will affect its operation. Be aware of recent changes to your network. Quality of RF link: Data communication depends first on the quality of the RF link. If you can establish and maintain a high-quality RF link, then you can be sure the link will carry high-speed data. If the quality of the RF link is degraded for some reason, the quality of the transmitted data will also degrade. Radio Hardware:There are three basic parts to a AWE: radio unit, antenna feed (cable, connectors, surge suppressors, patch cables etc.) and antenna.You can isolate faulty hardware using measurement and/or replacement methods. • Verify the radio unit with diagnostic tests (such as RSSI and link monitor tests), bench test a unit, or replace a unit. • Verify the antenna feed with a Site Master test set. Sweep cables, connectors and lightning suppressors, or exchange these parts for known good parts. • To verify the antenna you can sweep the antenna with the Site Master test set or exchange the antenna. Correct Unit Configuration: Units must be configured correctly, according to the network plan. Configuration errors can cause an inability to communicate or poor performance. The addition of units or changes to your system may require you to change configuration settings. Embedded Software: Operate with a proven software image. Download new software if you suspect that a unit’s software is corrupted. The following chart provides answers to some of the more common problems that can occur when installing and using a AWE bridge. 130 AWE 120-58 User Guide Troubleshooting Areas Troubleshooting Chart Indication Possible Cause Suggested Corrective Actions High BER Signal strength is too low Perform RSSI test to determine fade margin Align or change antennas or cables Ensure LOS between antennas Signal strength is too high Adjust antennas Increase distance between units Interference Change center frequency Increase RF power Change polarization of antennas Physically isolate antenna from source of interference or change physical location of antenna Bad radio (Tx/Rx) Bench test radio Exchange radio Bad antenna Visually inspect antenna for damage Sweep antenna Replace antenna Bad cable Visually inspect cable Replace cable Bad connectors Visually inspect connectors Replace cable/connectors Noisy power supply Replace power supply unit Temperature Determine ambient operating temperature is too high or low Increase or reduce ambient temperature.

This section provides some general guidelines for planning a wireless link, including the following: • Planning the physical layout of your system • Determining antenna and cable requirements • Determining configuration settings for units • Calculating a link budget Planning the Physical Layout You need to plan the physical layout of your wireless system. • Determine the number of remotes • Ensure LOS (line-of-sight) exists between units and determine coverage areas • Measure the distance between the base station and each remote unit • Consider the need for equipment shelters, electrical power and environmental requirements Determine the Number of Remotes Since the 12 Mbps data rate is shared between all units, the fewer the number of remote units, the faster each wireless link. Although a maximum of 1000 remotes is supported per base station, this number would result in low data rates. Instead, to ensure high data rates, Wi-LAN suggests a standard where 75 remotes can maintain constant 128 kbps communication with a base station. Since it is unlikely that all units will be active at the same time, the total number of remotes for planning purposes can be increased by a factor of three, so that a maximum of 225 (3 x 75) remotes per base station is recommended. This should enable all users to easily achieve 128 kbps performance. Ensure LOS and Determine Coverage Area Ensure the availability of a clear, LOS (line-of-sight) radio path between base station and all its remotes. Plot the coverage area of each base station on a map, and determine which base station will service which remote unit. Plan some alternate links in case base station coverage areas overlap or if physical obstacles block the radio path to some remotes. APR 2002 Rev 03 135 Appendix A: Planning Your Wireless Link Measure the Distance Between Units Use a mapping method or GPS (global positioning system) to measure the distance between the base station and each remote, and check the radio path to identify any obstructions in the LOS path between the two antennas. Due to the high frequency and low output power permitted in the ISM bands, no obstructions can exist between the base station and the remote unit. Determine Shelter, Power and Environmental Requirements AWE units must be located in a weatherproof environment (a room, EMS cabinet or shelter) with an ambient temperature between 0º and 40º Celsius, and humidity from 0 to 95% non-condensing. Consider building, electrical power, heating and air conditioning requirements. Determining Antenna and Cable Requirements The signal from an indoor antenna can penetrate several walls, although metal obstructions or building features such as elevator shafts can deflect or inhibit radio waves. On-site testing is advised because all interiors are unique. If you plan to install antennas outdoors you need to consider several factors. • Ensure a clear line-of-sight radio path is available between each remote and its base station. • Ensure that Fresnel zone clearances are met. Identify obstructions that could degrade link performance now and in the future. • Obtain permission from building owners if you intend to install the antenna on a rooftop • Obtain 24-hour access to antennas, cables and equipment • Determine antenna mounting positions: the final position should be selected to enable physical shielding of the antenna at the back and sides from radio interference in the ISM band. • Consider potential wind load and ice loading impact on the antenna • Be aware of possible multipath effects: installing an antenna too close to reflective surfaces can cause signal problems. • Check local regulatory restrictions, such as height, on antenna mast usage in the identified location • Ensure that your antenna is properly grounded and installed according to local electrical codes. • Determine transmission cable lengths and plan cable routes. Minimize the length of the coaxial cable because the longer the cable, the greater the cable losses. • Calculate the fade margin—a minimum 15 dB fade margin is required to ensure the reliability of your wireless link. • Determine Ethernet cable lengths and plan cable routes. WARNING Correct antenna installation is critical to the safe operation and performance of your system. Antennas should always be professionally installed. More information about antennas is provided in Antenna Basics 136 , page 142. AWE 120-58 User Guide Determining Unit Configuration Settings Determining Unit Configuration Settings Configuration settings of units should be determined before installation to ensure easy installation and to reduce installation costs. An information sheet should be prepared for each unit that specifies the basic configuration settings of that unit. • Unit Name • IP Address • Subnet Mask • Station Type • Station Rank • Center Frequency • Security passwords • Scrambling Code • Acquisition Code • Remote Unit RF Group • Transmit Power Level You may also specify other settings such as remote distance, IP filtering and throttling. Calculating a Link Budget Proper path planning ensures that each end of the RF link receives sufficient signal power to maintain the desired Bit Error Rate (BER). The effectiveness and reliability of your RF link depends on several factors. • Antenna gain and other characteristics • Distance between antennas and obstructions in the RF path • Location and height of antennas • Length and type of coaxial cable connecting the unit to the antenna These factors are considered when you calculate your link budget. The calculation indicates, on paper, if your radio link is feasible over a given distance and path and if your RF link meets regulatory requirements. Link budgets are typically expressed in decibels (dB). The following variables are used to calculate the link budget. Variable Description System Gain Maximum path loss that the system can support for usable data transmission EIRP (Effective Isotropically Radiated Power) Power radiating from an antenna taking into account the output power from the transmitter, connector losses, cable losses and antenna gain Antenna Gain Gain of the antenna over a dipole (dBd) or theoretical (dBi) Propagation Loss Signal loss experienced as it travels through the air, expressed in dB APR 2002 Rev 03 137 Appendix A: Planning Your Wireless Link Variable Description Fresnel Radius Distance around line-of-sight that must be clear of obstacles Cable Loss Signal loss experienced as it passes through the coaxial cable, expressed in dB Path Loss Total loss from one end of the path to the other. Includes propagation losses, cable losses and any other losses that impact the system performance Each variable is described below. System Gain The system gain of a radio system is the difference between the transmitted power and a receiver’s sensitivity threshold. The system gain of the AWE 120-58 is calculated as follows. Note: For the sake of simplicity, a Tx Power value of 20dBm is used in the following calculations. Formula: System Gain = Transmission Power - Receiver Sensitivity @ 10-6 BER Variables: Tx Power = 21 dBm Receiver Sensitivity = –80 dBm (receiver sensitivity @ 10-6 BER) Calculation: 21dBm – (–80) dBm = 101 dB To ensure reliable communications, the system gain plus all antenna gains must be greater than the sum of all losses. For a reliable link,Wi-LAN recommends that the system gain plus all antenna gains be greater than the sum of all losses by 15 dB. This amount is the fade margin. EIRP (Effective Isotropically Radiated Power) EIRP is the power that radiates from an antenna, taking into account the output power from the transmitter, the connector and cable losses, and the antenna gain. Unlike the Tx output power of the devices, EIRP takes account of antenna gain and cable losses. Antennas use directional gain to increase the effective radiated power. Losses such as cable losses reduce the effective radiated power. You calculate the EIRP as follows. Formula: EIRP = Tx Power (dBm) - Cable Losses (dB) - Connector Losses (dB) + Antenna Gain (dBi) Note: The FCC regulatory body has set the EIRP limit to +36 dBm for point-to-multipoint applications per FCC 15.247(b)(3). For point-to-point applications EIRP can be >36 dBm as per FCC 15.247(b)(3)(ii). Visit www.fcc.gov for the most current information. Industry Canada specifies the EIRP limit to ≤ 4W (+36 dBm) as per RSS-210, 6.2.2(o)(b) for point-to-multipoint applications and 200W (+23 dBW) for point-to-point applications. Visit www.ic.gc.ca for the most current information. 138 AWE 120-58 User Guide Calculating a Link Budget Antenna Gain To ensure the best range and interference suppression, the external antenna should be directional, focusing the radio energy in one direction (toward the other end of the link) rather than onmi-directional. Use of a directional antenna also reduces interference from other systems operating at the same frequency. Note: In some situations, you may want to use an omni-directional antenna in your system design. For example, you would use an omni-directional antenna for a base station with remote sites situated in a 360º path around it. When you select a Wi-LAN approved antenna, pay particular attention to the gain specification. When you select an antenna for a remote station, select an antenna with a gain that provides at least 15 dB fade margin. Antenna gain is specified in either dBi or dBd. When an antenna is specified in dBd, add 2.14 dB to the value to convert it to dBi. Propagation Loss Propagation loss is the attenuation (reduction) in RF signal energy as it travels through space. In most wireless systems, losses through space are the major contributor to signal attenuation. When you know the intended installation locations of the base and remote stations, determine the physical line of sight distance and then calculate the RF attenuation as follows: Formula: Attenuation (dB) for 5.8 GHz band = 108 dB + 20log(dkm) where: dkm = Distance in Kilometers 108 dB = Pathloss Constant in the 5.8 GHz band Fresnel Zone It is essential that you locate your antennas at maximum above-ground height to ensure that all ground-based obstructions are cleared from the Line of Sight path and the Fresnel Zone. The Fresnel Zone is the expansion of the RF signal radio angles in the vertical plane near the middle of the RF path. Fresnel Zone First Fresnel Zone Line of Sight The maximum Fresnel Radius indicates that this path must be kept clear of obstructions. Fresnel Radius Ground APR 2002 Rev 03 139 Appendix A: Planning Your Wireless Link For the 5.8 GHz band, the approximate Fresnel Radius is calculated as follows. Formula: Fresnel Radius (meters)= 2.2 d km + ( d km ⁄ 8.12 ) Cable Loss Cable and connector losses affect the operation of the wireless link and therefore should be kept to a minimum by minimizing cable lengths and carefully selecting the type of cable. The two primary coaxial cable specifications for the AWE 120-58 are: • Cable must be 50 ohms nominal impedance • Cable must be of a low loss type The following is an example of cable loss ratings at 5.8 GHz. Cable Type LDF2-50 LDF4-50A LDF4.5-50 Loss (dB/meter) 0.32 0.22 0.16 Note: When you calculate path loss, you will add 1dB at each end of the link to compensate for connector losses in addition to the cable loss value. Path Loss Path loss describes the total RF attenuation throughout the system from Tx antenna to Rx antenna. This includes the losses as the RF signal travels through space plus Tx and Rx cable loss, and Tx and Rx connector loss. Use the following formula to calculate path loss. Formula: Path Loss = Tx and Rx Cable Loss + Tx and Rx Connector Loss + Propagation Loss Once you know the path loss, you can compare the value to the system gain value. If the system gain value is greater than the path loss, the link is feasible. See System Gain , page 138 for more information about system gain. Fade Margin Fade margin is the amount by which the system gain plus the total antenna gain exceeds the path loss. Formula: Total antenna gain = Tx Antenna Gain + Rx Antenna Gain As calculated, the fade margin is the number of dB that the received signal strength exceeds the minimum receiver sensitivity.You require some level of fade margin for any wireless system to compensate for RF path fading due to weather conditions or multipath interference. The Wi-LAN recommended fade margin for the AWE 120-58 is a minimum of 15 dB. The sum of the cable losses, connector losses, propagation losses, and the 15 dB required fade margin should be less than the sum of the system gain and antenna gain. 140 AWE 120-58 User Guide Link Budget Example Link Budget Example System Gain + Antenna Gain ≥ Propagation Loss + Desired Fade Margin + Cable Losses + Connector Losses Formulas: or Actual Fade Margin ≥ System Gain + Antenna Gain – Propagation Loss – Cable Losses – Connector Losses and Actual Fade Margin ≥ Desired Fade Margin where: System Gain = Tx Power – Rx Sensitivity Antenna Gains = Tx Antenna Gain + Rx Antenna Gain Cable Losses = Base Cable Losses + Remote Cable Losses Connector Losses = Base System Connector Losses + Remote System Connector Losses Variables: Desired Fade Margin = 15 dB Tx Power = 21 dBm Rx Sensitivity = –80 dBm Tx Antenna Gain = 27 dBi Rx Antenna Gain = 27 dBi Propagation Loss for desired range of 10km = 108 + 20 x log(10) = 128 dB Tx Cable Losses (5m LDF2-50) = 5 * 0.32 = 1.6 dB Rx Cable Losses (5m LDF2-50)= 5 * 0.32 = 1.6 dB Tx Connector Losses = 1 dB Rx Connector Losses = 1 dB Variable Calculations: System Gain = 21 - (–80) = 101 dB Antenna Gains = 27 + 27 = 54 dBi Cable Losses = 1.6 + 1.6 = 3.2 dB Connector Losses = 1 + 1 = 2 dB Actual Fade Margin Calculation: Actual Fade Margin = 101 + 54 – 128 – 3.2 – 2 = 21.8 dB Analysis: A goal of Actual Fade Margin ≥ 15 dB is achieved. The values for cable and connector losses in this example are only for illustration.You will need to work these out for your specific installations. APR 2002 Rev 03 141 Appendix A: Planning Your Wireless Link Antenna Basics Antennas focus and absorb radio energy in specific directions, depending on their design. AWE 120-58 antennas must be tuned to 5.7250 – 5.8500 GHz. This section contains basic information about antenna parameters and how to select and install antennas for use in your wireless system. Antenna characteristics, mounting location, and correct operation of antennas are critical to a wireless link. Antenna Parameters Parameter Description Gain • Antennas have a gain associated with them, which is a measure of their ability to amplify signals in their tuned band • Antenna gain is achieved by focusing the signal. A higher gain antenna has a more compressed signal dBd vs. dBi • Antenna gain must be measured over a known reference and is often expressed as either dBd or dBi • dBd is antenna gain referenced over a half-wave dipole which is an antenna that has a donut shaped radiation pattern • dBi is antenna gain referenced over an isotropic radiator which is a theoretical antenna that radiates equally in all directions (e.g. the sun) • Wi-LAN references antenna gain in dBi. The conversion factor is 0 dBd = 2.14 dBi Beamwidth • Describes how a signal spreads out from the antenna, and the range of the reception area • Beamwidth is measured between the points on the beam pattern at which the power density is half of the maximum power. This is often referred to as the –3 dB points • A high gain antenna has a very narrow beamwidth and may be more difficult to align Downtilt or uptilt • Some antennas have either an associated downtilt or an uptilt. The tilt further focuses the signal downward or upward with respect to the horizon • Tilt may be either electrically built into the antenna or achieved mechanically with the mounting gear • Downtilt or uptilt may be required when there is a significant deviation between the elevation of the remote site(s) and the base site F/B • Front-to-back ratio • Directional antennas focus the signal in a forward path. Achieved by directing the signal in one direction that reduces the signal in the opposite direction • A higher gain antenna typically has a greater F/B ratio 142 AWE 120-58 User Guide Antenna Basics Parameter Description XPD • Polarity and Cross-Polarization Discrimination (XPD) • Antennas have an associated polarity, which is the orientation of the radiating element with respect to earth • Antennas are usually described as vertical, horizontal, or circularly polarized. The polarity of all antennas used in a system must be the same • Cross-Polarization Discrimination specifies the signal isolation achieved when the receiving element is perpendicular to the radiating element. Can be advantageous when co-locating radio systems VSWR • Voltage standing wave ratio • VSWR is the voltage ratio of minimum to maximum across a transmission line • A VSWR of 2.0:1 or less in an antenna is considered effective. Most antennas have a VSWR of 1.5:1 • For example, when using a radio with a 4 W output with an antenna VSWR of 1.5:1, the reflected power will be 160 mW Implementation Considerations Some key items to consider when selecting and installing antennas for your wireless network follow. Item Description Absorption • Antennas mounted too close to “soft” objects, such as trees, may experience a reduction in signal strength due to absorption • Absorption is most often encountered in applications installed during the fall or winter months, and the problem does not become evident until the spring Diffraction • Diffraction occurs when a radio signal reflects or bounces off of a solid object • Level of diffraction could lead to connectivity problems if the remaining signal level is too low • Two types of diffraction are shadowing and multipath Shadowing • Shadowing is a form of diffraction that is typically caused when antennas are mounted too close to a structure and they lose a portion of the signal lobe due to reflection. The receive antenna is in a shadowed area • To minimize shadowing, ensure that there is adequate height above structures when mounting antenna equipment Multipath Interference • Multipath is a form of diffraction in which the reflected signal arrives at the receiver at different times which confuses the receiver • Multipath may be interpreted as interference by the receive antenna and can result in bit errors and processing delays APR 2002 Rev 03 143 Appendix A: Planning Your Wireless Link Wi-LAN Approved Antennas Antennas must be selected from the following list of Wi-LAN approved antennas. Antennas must be connected using transmission cables having the specified minimum lengths.

The following are some initial questions you should ask before selecting an antenna. 144 • What is the operating frequency range? • Will this be a point-to-point or point-to-multipoint application? Ensure that you consider if the application will change in the future. • What are the coverage requirements? • What is the gain requirement? • What is the elevation of the remote site(s) with respect to the base station and will additional downtilt/uptilt be necessary at either the base or remote site to compensate? • Will there be any obstructions in the path? • Will systems be co-located? What polarity will be used? • What are the regional environmental conditions? For example, is there windloading, salt air, excessive moisture, ice buildup etc.? • What is the antenna lifetime expectation? • What are the site and mounting options? • What are the restrictions in the locale regarding the effective radiated power permitted from the antenna? • Will antenna appearance be a factor? AWE 120-58 User Guide Antenna Basics Antenna Installation Factors Some factors you should consider when installing antennas into your wireless system are listed below. Factor Description Maximizing the AWE 120-58’s Capabilities • • • • • • • Safety • Proper grounding of antenna apparatus in accordance with respective Electrical Code(s) is crucial • Wi-LAN recommends using a surge arrestor where the antenna cable enters the building • All installations should be completed by a qualified and competent RF technical EIRP • Effective Isotropically Radiated Power (EIRP) • EIRP is the amount of power that is transmitted to the air from the antenna • EIRP levels depend on the power of the radio transmitter, the gain of the antenna, and the losses incurred in the antenna cable • EIRP must not exceed 4 W or 36 dBm in Canada and the United States for point-to-multipoint applications. Note:EIRP = Power out of unit – Power lost in cable + Gain in power from Antenna Fade Margin See Calculating a Link Budget LOS • Line of Sight (LOS) • LOS is a football shaped pattern known as the Fresnel Zone, which must be kept clear of obstructions. See Fresnel Zone , page 139 for more information • Visual line of sight must be achieved. When standing at the antenna position, you must be able to see the remote antenna APR 2002 Rev 03 Minimize obstructions in the radio path Line Of Sight (LOS) is crucial for reliability Ensure that equipment is installed correctly Ensure proper grounding, testing, and alignment of antennas Install in environmental conditions that are suitable for the AWE unit Select proper antennas and cable for the application Ensure sufficient gain for the intended application , page 137 145 Appendix A: Planning Your Wireless Link Minimal Clearance Above Obstructions For the AWE 120-58, the absolute minimum clearance above obstructions requirements are as follows (in meters): 2.2 m × d km @ 5.8 GHz Some example clearance requirements for 5.8 GHz links follow. Distance (km) Clearance (m) Distance (miles) Clearance (ft) 0.5 1.6 0.5 6.5 2.2 9.3 3.2 13.3 3.9 16.7 5.2 22.6 6.9 31.3 10 8.0 10 37.3 15 10.8 15 54.3 Note: There is also a correction factor to compensate for curvature of the earth. This correction factor is not required when the correction value is negligible < 10 km. Installing Antennas Antennas must be installed professionally to ensure that the antenna operates properly and follows accepted safety, electrical, grounding and civil engineering standards. Ensure the following conditions. 146 • Dipole antennas are oriented vertically (point up). • Antennas for the system have the same polarity (vertical, horizontal or circular). • Connectors attaching the coaxial cable to the antenna are properly weatherproofed. • A drip loop is formed at the building entrance to prevent water flowing down the coaxial cable and entering the installation building. • The coaxial cable is secured to the supporting structure at one meter intervals to prevent wind damage and frost loading problems. • The antenna is firmly attached to the mast to prevent it from falling, yet has some flexibility so you can move the antenna to fine-tune its position. • The coaxial cable is connected to the antenna and to the Antenna port on both sides of the link (base and remote stations). • The antennas are grounded properly. AWE 120-58 User Guide Antenna Basics Fine-tuning Antennas You can fine-tune the antennas by physically moving the antenna. When the remote antenna is correctly aligned, the Air LED is orange, indicating communication with the base station.You can use the Receive and Transmit Tests to test the link while adjusting the antennas to minimize BER and lost packets and maximize received power.You can use the RSSI Test to maximize RSSI. Once antennas are adjusted to maximize performance, secure them properly to the support structures. Co-locating Units When AWE antennas are located on the same mast, you must take care to ensure the output power from one radio does not overpower another co-located bridge, even if the units are operating on different channels.You may need to install a signal attenuator to lower transmit power, use antenna polarity to your advantage, or adjust antenna uptilt or downtilt. Contact your distributor for antenna and installation assistance when co-locating units.

SNMP agent software is contained in every AWE unit. Agent software enables a unit to interpret SNMP (Simple Network Management Protocol) MIB (Management Information Block) commands. SNMP management software is installed on a networked PC or workstation and enables a network administrator to remotely manage AWE units. If you have SNMP manager software installed on a networked PC or workstation, you can configure, monitor and control AWE units via the Ethernet or air. SNMP network management software is available commercially and as shareware (for example, you can download a free evaluation copy from www.mg-soft.com). MIB is simply a list of objects that SNMP can monitor.You can download a proprietary Wi-LAN MIB file from www.wi-lan.com or obtain a copy through the Wi-LAN Technical Assistance Center. The AWE 120-58 is MIB version 2 compliant. After you download the MIB file, you must compile the file with the SNMP management software compiler. SNMP Elements SNMP Element Description Manager Software installed on the network’s host computer and operated by the network administrator. From the host, the Manager configures Agents or polls Agents for information Agent Software that runs on each unit. An Agent accepts configuration commands from the Manager and collects network and terminal information specified in the MIB Management Information Block (MIB) A database that is accessed by a specific set of commands and executed using the SNMP manager. There is a standard MIB and a Wi-LAN customized MIB that stores information relevant to the operation of a wireless network APR 2002 Rev 03 157 Appendix D: SNMP Wi-LAN Object Identifier Nodes The AWE 120-58 uses SNMP version 1, which is MIB 2 compliant. All OID (Object Identifier) nodes in the AWE 120-58 private Wi-LAN MIB are numbered 1.3.6.1.4.1.2686.2.n where n is a private Wi-LAN MIB node number or branch of nodes. All nodes containing statistical information are cleared on power up and reset. Values in all writeable nodes are stored in Flash memory and are retained until overwritten by the administrator, even following power down or reset.

Configuration Via the Web Overview The AWE 120-58 is remotely configurable via the Web using a standard Web browser. All configuration parameters described in previous sections are configurable through this graphical interface. This section explains the process of accessing the web pages provided and comments on the layout of these pages, noting the differences between the Web interface and the menu interface. Accessing the Web Pages ➧ To start a configuration session via the Web 1. On your PC, open a web browser application and specify the IP address of the unit you wish to access in the URL field. For example, if the IP address of the unit is 192.168.1.100, the URL specified is: http:// 192.168.1.100. Press Enter to load the page. 2. A login prompt should now appear, requesting for a user name and password. Leave the user name blank. For the password field, enter the same password used to access the menu interface. Click on Enter to submit your password. 3. If the password is accepted, the main web interface screen should appear. Follow the instructions provided to continue your configuration session. Web Interface APR 2002 Rev 03 171 Appendix E: Configuration Via the Web Configuration Interface The layout of Web pages provided mirrors the layout of the menu interface; parameters grouped together in submenus described in previous sections are similarly grouped together in web “subpages”. Links to these pages are provided after user authentication is complete via a menu bar. Unit configuration is achieved by filling out forms provided by each configurable subpage. These pages are accessed by clicking on appropriate links in the menu bar. Pressing a form submit button will send your entry data to the unit for processing. Specified parameters are then updated (pending valid input and access permission), and any requested tasks are run. 172 AWE 120-58 User Guide Overview Differences Between the Menu Interface The one appreciable difference between the menu interface and the Web interface is the statistics submenu. For the Web interface, Link Monitor Statistics and RF/Ethernet Statistics, two distinct menus in the menu interface, are combined into one subpage. The link for this page is Monitor Statistics, located in the menu bar. Within this subpage, a link to Real-Time Statistics is provided. Accessing this link will load a JAVA ™ applet. This applet will query the unit periodically and report back to you via a live-update graphical statistics display. Note: Depending on the version of your browser,the Real-Time Statistics link may prompt you to install a JAVA™ Plug-in. If you receive this prompt and wish to load the Plug-in, your computer must have access to the Internet. APR 2002 Rev 03 173 Appendix E: Configuration Via the Web 174 AWE 120-58 User Guide Appendix F: Upgrading Software If necessary, you can upgrade the software of a AWE 120-58. This section explains how to use FTP to download a new software image to a AWE unit. Before you can download a new software image you need the following items. • A copy of the software image file • A PC connected to the AWE unit via the network • Basic network software installed on your PC, including ftp, ping, telnet, SNMP manager (optional) Obtaining New Software Images New software image files are available from the Wi-LAN support web page at www.wilan.com. Downloading Image Software 1. Obtain the new image files. 2. Open a DOS session on your PC. From Windows®, choose Start, Programs, MS-DOS Prompt. 3. Copy the new image files to a known directory, for example c:\wilan\images. (Create a new directory if a suitable directory does not already exist.) This directory is an example only. C:> copy c:\wilan\images 4. Go to the directory by typing cd c:\wilan\images and press Enter. 5. List the contents of the directory. Type dir and press Enter. The names of image files should be listed in the directory. APR 2002 Rev 03 175 Appendix F: Upgrading Software 6. Type ftp and press Enter where the IP address is the address of the AWE unit. The PC connects to the unit. This IP address is an example only. Enter the IP address of your unit. c:\wilan\images>ftp 192.168.3.85 Connected to 192.168.3.85 220 Wi-LAN AWE 120-58 Ethernet Bridge FTP Server User (192.168.3.85(none)): Note: ftp must be installed on your PC. 7. Type "awe" and press Enter. The password prompt appears. c:\wilan\images>ftp 192.168.3.85 Connected to 192.168.3.85 220 Wi-LAN AWE 120-58 Ethernet Bridge FTP Server User (192.168.3.85(none)):awe 331 Password required Password: 8. Type the supervisor password for the unit and press Enter. (Supervisor access is required to change unit settings–see Setting Menu Passwords , page 117). The ftp> prompt appears. 9. After the ftp prompt, type the following “put” command. ftp> put .\ Note: Leave a single space after “put.” where 176 Current directory that contains the image file (for example, c:\wilan\images) Name of the image file AWE 120-58 User Guide Activating New Software Images 10. Press Enter. The image file transfers from the PC to the unit. The status of the transfer, the file size and the transfer time are displayed. ftp>put .\ 200 Port set okay 150 Opening binary mode connection 226 Transfer complete 10484 bytes sent in 0.11 seconds (95.31 Kbytes/sec) ftp>bye Tip: If you type ftp> help, online instructions for using ftp are displayed. 11. Type bye and press Enter to exit ftp and return to the DOS window. 12. Activate the new software image. See Activating New Software Images, below. Activating New Software Images After you download new image files to a unit, you need to configure the unit to operate from the new image rather than from the current image. If you are on-site, you can use the Main Menu to select the default image. See Setting Default System Image , page 122. If you are at a remote location from the unit, you can use telnet to access the unit’s configuration menu or use SNMP manager software (SNMP parameter = defaultImage) to choose the default image file. See Appendix D: SNMP , page 157. Removing Old Software Images To delete old software images from a AWE unit, you must use ftp to connect to the unit, log in as a “supervisor” and delete images using the “ftp delete” command. Images The amount of flash memory available to store images is limited. To see the amount of memory available, see Viewing System Revision Information , page 37.
