$APR 2002 Rev 03 1 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.$

Description 2 AWE 120-58 User Guide License-Free ISM Bands 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.900 MHz 2.4 GHz5.8 GHz26 MHz Wide83.5 MHz Wide125 MHz Wide902 MHz 928 MHz2.4 GHz 2.4835 GHz5.725 GHz 5.85 GHz

Some System ApplicationsAPR 2002 Rev 03 3 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 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.BaseWired NetworkRemoteRouterMain Wired NetworkRouterHubSwitchFirewallSwitchHubFirewallWireless Link

Some System ApplicationsAPR 2002 Rev 03 5 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.

Description 6 AWE 120-58 User Guide Using a Repeater Base A base station can function as a repeater to enable wireless data communication around physical obstacles such as tall buildings or mountains. 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. Base Station as a Repeater Building a WAN LAN segments can be linked with AWE units to build a WAN (Wide Area Network). Wi-LAN networks are installed in many locations around the world.

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.ImportantThe 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.

Installation24 AWE 120-58 User GuidePerforming Simple Network TestsTo test units within a simple network you require two AWE 120-58 units, a LAN connection, a PC and a crossover Ethernet cable or hub connection. ➧ To perform a simple network test1. Connect the Ethernet port of the PC to the base station’s Power Inserter Unit “To LAN” port. You can either connect via a network hub or connect directly using an RJ45 crossover Ethernet cable.2. Connect the remote unit to the network as described in Step 1.Simple Network Test Setup3. 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.Base UnitPCLAN10/100 BaseT HUB10/100 BaseT CableDirect 10/100 BaseT Cable (Crossover)Cable connects toEthernet port via (StraightThrough)Cable10/100 BaseT2 mminimumPower Inserter UnitPower / Ethernet cableTo radioTo LAN

Installation26 AWE 120-58 User Guide5 Install UnitsThis section provides some guidelines about installing units in the ﬁeld.• 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.WARNINGAll antennas must be professionally installed following accepted safety, grounding, electrical, and civil engineering standards. ! CAUTIONNever 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.!

6 Test NetworkAPR 2002 Rev 03 27Point-to-Multipoint InstallationThe procedure for installing a point-to-multipoint system is the same as the procedure for installing a point-to-point system. Treat each link in a point-to-multipoint system as a single, point-to-point wireless link.Co-Location InstallationWhen 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 NetworkRun 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 NetworkAlways 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!

Installation28 AWE 120-58 User GuideNetwork Test SetupPreventative Maintenanceand MonitoringYou 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.IndoorAntennaIndoorAntennaBase Unit Remote UnitLAN10/100 BaseT HUBPC with LAN analyzer softwarePCTo radioTo LANPower Inserter Unit

IP Filter ConfigurationAPR 2002 Rev 03 45IP Filter ConﬁgurationTwo 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.Each IP address ﬁlter is deﬁned by a range and a base value. IP address ﬁltering improves system security and helps manage data throughput.IP Packet Filteringoff (disabled) All packets are passedon (enabled) Only IP (Internet Protocol) packets and ARP packets can passIP Address Filteringoff (disabled) Packets from all LAN-side IP addresses can passon (enabled) Packets from all LAN-side IP addresses are subject to IP ﬁlterDefault IP Address FilteringPassBlockIf IP Address Filtering is off, this item is inactive.

Configuration46 AWE 120-58 User GuideViewing IP Filter Conﬁguration➧ To view current IP ﬁlter conﬁgurationTwo sample conﬁgurations below show how IP address-ﬁltering works.Example 1: 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).Example 2: H - Help IP Filter ConfigurationIP Packet Filtering -> offIP Address Filtering onDefault IP Address Filtering Pass Filter Entry Range (0-255) Base Address State------------------- ------------------- ------------------- ------------------- 1 100 192.168.1.1 Block 2 10 192.168.1.51 Pass

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.

Configuration64 AWE 120-58 User GuideIf this unit participates in the Spanning Tree Protocol, the conﬁgurable parameters mentioned above, Bridge Priority, Port Priority and Port Path Cost, are communicated to all other participants in the bridged network in a Spanning Tree Protocol packet. 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 loopsIf 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.Enabling Spanning Tree➧ To enable the Spanning Tree Protocol1.

Configuration82 AWE 120-58 User GuideAdjusting Throttling (Remote Station Only)Throttling enables you to control the rate that data passes though a remote, so data throughput can be adjusted to make the data rate compatible with the rest of the system. 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. The default setting is to disable throttling.➧ To enable throttling1. From the Main Menu, select RF Station Configuration and press Enter. The RF Station Conﬁguration menu is displayed.2. Select Throttle Enable and press Enter. The data ﬁeld highlights.3.

RF Station ConfigurationAPR 2002 Rev 03 83Setting Tx Power Automatically (Remote Station Only)Output Power Control Mode can be used to adjust a remote unit’s Tx power automatically. 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 WorksLink 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.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 Noise FloorFactory-set Power CeilingUser-specified Power Ceiling(Base Tx Power Level + Signal Margin)Signal Power Signal MarginPower Level Base Tx PowerLevelAutomatic power adjustment moves power level up and downOperating Tx Power Level 0

Configuration84 AWE 120-58 User Guidelevel 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.

Configuration94 AWE 120-58 User GuideSetting the Station RankStation Rank is deﬁned two different ways, which depend on the station type: For a base station, rank is the total number of remotes that a base will poll. 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.Note: Dynamic polling gives you some control over the polling process.

Radio Module ConfigurationAPR 2002 Rev 03 95Setting the Center FrequencyA center frequency deﬁnes the RF channel that a unit uses to transmit and receive. 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 FrequenciesA simpliﬁed diagram of the spectrum around a center frequency (when transmitting) is shown below. 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. 16 MHz16 MHz 33 MHzCenter Frequency66 MHzDataSideSideCenter Frequency SpectrumLobeLobeRegion5.7410 GHz 5.8338 GHz

Configuration96 AWE 120-58 User Guide Some examples of center frequency separation and performance ratings are provided below.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. For best performance, choose center frequencies that are separated as much as possible and non-overlapping. 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.

Configuration100 AWE 120-58 User GuideSetting the Acquisition CodeAn acquisition code is a unique code contained within the preamble of a transmitted message. Units search the air for messages that begin with a particular acquisition code. Messages without the correct code are treated as interference and are rejected by a unit. Messages with the correct code are accepted and processed. Acquisition codes serve to isolate units from each other, especially when several units operate in close proximity or at the same frequency in a multiple-sector or multi-cell environment. All units in the same network must have the same acquisition code in order to communicate with each other.➧ To set the acquisition code1.

Configuration102 AWE 120-58 User GuideSetting 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 ModeWhen repeater mode is disabled (Repeater Mode = off), the base station functions normally (it polls remotes and links the various segments of the network).

Radio Module ConfigurationAPR 2002 Rev 03 105Setting Dynamic Polling Level (Base Station Only)Dynamic polling improves system performance by reducing overhead due to idle remote units. 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 level1. From the Main Menu, select RF Station Configuration and press Enter. The RF Station Conﬁguration menu is displayed.1. Select Dynamic Polling Level and press Enter. The data ﬁeld highlights.2.

Configuration106 AWE 120-58 User GuideSetting Remote Unit RF GroupThe 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 SystemRemote 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 SystemRF Group = 14BaseRemoteRF Group = 14RemoteRepeaterMode = offRF Group = 20RemoteRF Group = nn = 1 – 63Human ResourcesPayrollR&DRemoteRF Group = 0RF Group = 0RemoteBaseRepeaterMode = offRemoteRF Group = 0RF Group = 0Company 3Company 2Company 1

Radio Module ConfigurationAPR 2002 Rev 03 107A 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)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.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).Repeater Mode (Base only)RF Group(Remote only)SystemType System CharacteristicsRepeater Mode = off1–63 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 = off0 Closed Remotes can communicate only with the base station—they cannot talk to each otherRepeater Mode = on1–63 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 numberClosedRemote RemoteBaseSystemRepeaterMode = onRF Group = 4RF Group = 4RemoteRF Group = 4RemoteRF Group = 4 n = 1 – 63 n = 1 – 63 n = 1 – 63 n = 1 – 63MountainNo direct communcation possible due to obstacle

APR 2002 Rev 03 129TroubleshootingAdministrative Best PracticesBy performing some administrative best practices and preventative maintenance, you can prevent many problems with your system, or become aware of minor problems before they become serious ones. 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.

Troubleshooting130 AWE 120-58 User GuideTroubleshooting AreasThere 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.

APR 2002 Rev 03 135Appendix A: Planning Your Wireless LinkTo ensure an effective and reliable wireless link, you ﬁrst need to perform some network planning. 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 budgetPlanning the Physical LayoutYou 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 requirementsDetermine the Number of RemotesSince 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 AreaEnsure 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.

Appendix A: Planning Your Wireless Link136 AWE 120-58 User GuideMeasure the Distance Between UnitsUse 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 RequirementsAWE 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 Antennaand Cable RequirementsThe 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.More information about antennas is provided in Antenna Basics , page 142.WARNINGCorrect antenna installation is critical to the safe operation and performance of your system. Antennas should always be professionally installed.!

Determining Unit Configuration SettingsAPR 2002 Rev 03 137Determining Unit Conﬁguration SettingsConﬁguration 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 LevelYou may also specify other settings such as remote distance, IP ﬁltering and throttling.Calculating a Link BudgetProper 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 antennaThese 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 DescriptionSystem Gain Maximum path loss that the system can support for usable data transmissionEIRP (Effective Isotropically Radiated Power)Power radiating from an antenna taking into account the output power from the transmitter, connector losses, cable losses and antenna gainAntenna 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

Appendix A: Planning Your Wireless Link138 AWE 120-58 User GuideEach variable is described below.System GainThe 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.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.Fresnel Radius Distance around line-of-sight that must be clear of obstaclesCable Loss Signal loss experienced as it passes through the coaxial cable, expressed in dBPath 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 performanceFormula: System Gain = Transmission Power - Receiver Sensitivity @ 10-6 BERVariables: Tx Power = 21 dBmReceiver Sensitivity = –80 dBm (receiver sensitivity @ 10-6 BER)Calculation: 21dBm – (–80) dBm = 101 dBFormula: 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.Variable Description

Calculating a Link BudgetAPR 2002 Rev 03 139Antenna GainTo 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 LossPropagation 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:Fresnel ZoneIt 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 ZoneFormula: Attenuation (dB) for 5.8 GHz band = 108 dB + 20log(dkm)where:dkm = Distance in Kilometers108 dB = Pathloss Constant in the 5.8 GHz bandFirst Fresnel ZoneLine of SightFresnel RadiusGroundThe maximum Fresnel Radius indicates that this path must be kept clear of obstructions.

Appendix A: Planning Your Wireless Link140 AWE 120-58 User GuideFor the 5.8 GHz band, the approximate Fresnel Radius is calculated as follows.Cable LossCable 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 typeThe following is an example of cable loss ratings at 5.8 GHz.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 LossPath 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.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 MarginFade margin is the amount by which the system gain plus the total antenna gain exceeds the path loss. 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.Formula: Fresnel Radius (meters)= Cable Type LDF2-50 LDF4-50A LDF4.5-50Loss (dB/meter) 0.32 0.22 0.16Formula: Path Loss = Tx and Rx Cable Loss + Tx and Rx Connector Loss + Propagation LossFormula: Total antenna gain = Tx Antenna Gain + Rx Antenna Gain2.2 dkm dkm 8.12⁄()2+

You will need to work these out for your speciﬁc installations.Formulas: System Gain + Antenna Gain ≥ Propagation Loss + Desired Fade Margin + Cable Losses + Connector LossesorActual Fade Margin ≥ System Gain + Antenna Gain – Propagation Loss – Cable Losses – Connector LossesandActual Fade Margin ≥ Desired Fade Marginwhere:System Gain = Tx Power – Rx SensitivityAntenna Gains = Tx Antenna Gain + Rx Antenna GainCable Losses = Base Cable Losses + Remote Cable LossesConnector Losses = Base System Connector Losses + Remote System Connector LossesVariables: Desired Fade Margin = 15 dBTx Power = 21 dBmRx Sensitivity = –80 dBmTx Antenna Gain = 27 dBiRx Antenna Gain = 27 dBiPropagation Loss for desired range of 10km = 108 + 20 x log(10) = 128 dBTx Cable Losses (5m LDF2-50) = 5 * 0.32 = 1.6 dBRx Cable Losses (5m LDF2-50)= 5 * 0.32 = 1.6 dBTx Connector Losses = 1 dBRx Connector Losses = 1 dBVariable Calculations:System Gain = 21 - (–80) = 101 dBAntenna Gains = 27 + 27 = 54 dBiCable Losses = 1.6 + 1.6 = 3.2 dBConnector Losses = 1 + 1 = 2 dBActual Fade Margin Calculation:Actual Fade Margin = 101 + 54 – 128 – 3.2 – 2 = 21.8 dBAnalysis: A goal of Actual Fade Margin ≥ 15 dB is achieved.

Appendix A: Planning Your Wireless Link142 AWE 120-58 User GuideAntenna BasicsAntennas 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 ParametersParameter DescriptionGain • 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 signaldBd 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 dBiBeamwidth • 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 alignDowntilt 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 siteF/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

$Antenna BasicsAPR 2002 Rev 03 143Implementation ConsiderationsSome key items to consider when selecting and installing antennas for your wireless network follow.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 systemsVSWR • 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 mWItem DescriptionAbsorption • 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 springDiffraction • 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 multipathShadowing • 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 equipmentMultipath 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 delaysParameter Description$

Appendix A: Planning Your Wireless Link144 AWE 120-58 User GuideWi-LAN Approved AntennasAntennas must be selected from the following list of Wi-LAN approved antennas. Antennas must be connected using transmission cables having the speciﬁed minimum lengths.There are several factors to consider when choosing the right antenna for a wireless application. The following are some initial questions you should ask before selecting an antenna.• 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?AntennaDescription Number Gain (dBi)5.8 GHz Cushcraft directional planar S57212AMP 12 Note: 1 One of the following cables with the specified minimum length must be connected to the antenna:5.8 GHz European 55 degree H-sector 1SA17-55H/449 1175.8 GHz European 55 degree V-sector 1SA17-55V/4501175.8 GHz MTI directional/flat planar MT-10010 32 LMR400 6 m5.8 GHz MTI directional/flat planar MT-10011 28 LMR600 7 m5.8 GHz TIL-TEK directional/dish TA-5224M 28.5 LMR900 13 m5.8 GHz TIL-TEK directional/dish w/radome TA-5224MR 28.5 LDF4-50A 10 m5.8 GHz TIL-TEKdirectional/dish TA-5248M 34.2 LDF4.5-50 13 m5.8 GHz TIL-TEK directional/dish w/radome TA-5248MR 34.25.8 GHz TIL-TEK directional/dish TA-5272M 37.55.8 GHz TIL-TEK directional/dish w/radome TA-5272MR 37.5

Antenna BasicsAPR 2002 Rev 03 145Antenna Installation FactorsSome factors you should consider when installing antennas into your wireless system are listed below.Factor DescriptionMaximizing the AWE 120-58’s Capabilities• 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 applicationSafety • 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 technicalEIRP • 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 AntennaFade Margin See Calculating a Link Budget , page 137LOS • 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

Appendix A: Planning Your Wireless Link146 AWE 120-58 User GuideMinimal Clearance Above ObstructionsFor the AWE 120-58, the absolute minimum clearance above obstructions requirements are as follows (in meters): @ 5.8 GHzSome example clearance requirements for 5.8 GHz links follow. 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 AntennasAntennas 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.• 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.Distance(km)Clearance (m)Distance(miles)Clearance (ft)0.5 1.6 0.5 6.51 2.2 1 9.32 3.2 2 13.33 3.9 3 16.75 5.2 5 22.68 6.9 8 31.310 8.0 10 37.315 10.8 15 54.32.2mdkm×

Antenna BasicsAPR 2002 Rev 03 147Fine-tuning AntennasYou 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 UnitsWhen 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.

APR 2002 Rev 03 157Appendix D: SNMPAbout SNMP MIBThree elements are required to use SNMP: agent software, management software and a MIB ﬁle. 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 ElementsSNMP Element DescriptionManager 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 informationAgent Software that runs on each unit. An Agent accepts conﬁguration commands from the Manager and collects network and terminal information speciﬁed in the MIBManagement 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

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 Web1. 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

Appendix E: Configuration Via the Web172 AWE 120-58 User GuideConﬁguration InterfaceThe 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.

OverviewAPR 2002 Rev 03 173Differences Between the Menu InterfaceThe 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.

$APR 2002 Rev 03 175Appendix F: Upgrading SoftwareIf necessary, you can upgrade the software of a AWE 120-58. This section explains how to use FTP to download a new software image to a AWE unit.Before you can download a new software image you need the following items.• A copy of the software image ﬁle• A PC connected to the AWE unit via the network• Basic network software installed on your PC, including ftp, ping, telnet, SNMP manager (optional)Obtaining New Software ImagesNew software image ﬁles are available from the Wi-LAN support web page at www.wilan.com.Downloading Image Software1. Obtain the new image ﬁles.2. Open a DOS session on your PC. From Windows®, choose Start, Programs, MS-DOS Prompt.3. Copy the new image ﬁles to a known directory, for example c:\wilan\images. (Create a new directory if a suitable directory does not already exist.)4. Go to the directory by typing cd c:\wilan\images and press Enter.5. List the contents of the directory. Type dir and press Enter. The names of image ﬁles should be listed in the directory.C:> copy <image filename> c:\wilan\imagesThis directory is an example only.$

The PC connects to the unit.Note: ftp must be installed on your PC.7. Type "awe" and press Enter. The password prompt appears.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.Note: Leave a single space after “put.”where.Current directory that contains the image ﬁle (for example, c:\wilan\images)<image filename> Name of the image ﬁlec:\wilan\images>ftp 192.168.3.85Connected to 192.168.3.85220 Wi-LAN AWE 120-58 Ethernet Bridge FTP ServerUser (192.168.3.85(none)):This IP address is an example only.

$Activating New Software ImagesAPR 2002 Rev 03 17710. 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.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 ImagesAfter 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 ImagesTo 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.
