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 license-exempt 5.7250 – 5.8500 GHz ISM radio band and
has a maximum raw wireless data rate of 12.0 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 Internet 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). Contentionless polling ensures efficient access to remote data
networks.
• Is self-contained and easy to use. Simply connect a AWE 120-58 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 adjustable Tx power level, 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.
About Spread Spectrum
Three license-free 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

AWE 120-58 Installation & Configuration 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:
• Fast throughput: A wide bandwidth means fast data throughput.
• 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. Upon request, Wi-LAN can assign a
customer a data packet security code so that a customer can only receive transmissions from
another AWE with the same code.
• 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:
At least one unit in your wireless network must be configured as 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 16 for information about setting up a base station.

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. Because 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 19 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 77 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 esnure high levels of data throughput. See
Determine the Number of Remotes, page 111 for
more information.

Creating a Network with Cells
Cells or data nodes can be created with AWE units to maxmimize 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.

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 foreward" 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. You can contact Wi-LAN for help designing your network.

Obtain Network Plan
The network plan describes the network in detail, including the following:
• Type and number of units
• Physical layout
• Configuration settings for each unit
• Site names, IP addresses and links
• Antenna types, RF cables and cable lengths, surge suppressors, terminators
• Network cable types and lengths
• Grounding kits and backup power requirements
• Link budget
• Floor plans and equipment cabinet requirements.
The network plan must be completed before any equipment is installed. See Appendix A: Planning Your Wireless
Link, page 111 for more information about network plans.
Check your equipment and tools: Ensure that you have all the required parts and equipment specified in
the network plan. You will require a Bench Test Kit (9000-0034) and some tools to install and configure units–

Bench Test Units
In this section, you will perform the following tasks:
• Ensure that a basic RF link exists between a base station and a remote unit.
• Test the basic link with Link Monitor and adjust Tx power level.
• Perform some simple network tests.
Establishing a Basic RF Link
This test ensures that a basic RF link exists between a base station and a remote unit.
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 16.
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 19.
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..

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.
Basic Test Setup
4. Power up the base station. The green Power LED is ON. The Air LED of the base unit is red. This Air LED
color indicates that the unit is transmitting data but is not receiving a response. (The reason is that the
remote is powered off.)
5. Power up the remote unit. The green Power LED is ON. The Air LED of the remote unit turns orange
and the Air LED of the base station also turns orange as both units send and receive data from each
other. Orange is the normal Air LED color.
The color of the Air LED during this step indicates the following conditions.
Note: If antennas are placed too close together, the strong transmit signal will saturate the receiving unit.
Fine-tune antennas by changing antenna orientations until the Air LED is orange.
Next, you will test the link with the Link Monitor test and adjust the Tx power level to obtain a fade margin
of 15–30 dB. .
Orange (both stations) Units are continuously sending and receiving sync packets
Red (base station) Stations are configured incorrectly, and the base station is
transmitting without receiving acknowledgment

Testing the Link and Adjusting Tx Power
A basic RF link is established when the base station and remote unit can receive and transmit data to each
another (indicated by orange Air LEDs on both units). Once you have established a basic RF link, you test the
link by running the Link Monitor test and viewing the link statistics. Finally, you adjust the Tx Power of the
base and remote units to obtain a 15–30 dB fade margin.
➧ To test the RF link and adjust Tx power
1. Connect the test PC to the serial port of the base station or remote unit. See Connecting PC to Serial Port,
page 17.
2. Log in to the unit and go to the Main Menu.
3. Select RF Station Configuration and press Enter. The RF Station Configuration window is
displayed.
• Select Operating Mode. Press the arrow keys to select Normal mode.
• Select RF Transmit Status. Select unblocked.
• Select Link Monitor Remote Station Rank. Enter the rank of the unit that you want to
link test. (The rank is the identification number of the unit. The rank of a remote can be any num-
ber from 1 – 1000. The rank number of the the base station is always 0. See Setting the Station Rank,
page 69.)
• Select Link Monitor Period. Enter a link monitor period of 1. (A value of 1 means that 50%
of available data packets will carry test data. The higher the period number, the fewer the number
of data packets that will carry test data. See Setting the Link Monitor Period, page 61 for more infor-
mation.) The Link Monitor test starts as soon as a non-zero value is entered in the field.
Next, you view the link statistics and adjust Tx power level.

• Remote to Base BER = 0.0E+00
• Base to Remote Corr Power between 15 – 50 dB
• Remote to Base Corr Power between 15 – 50 dB
If the Corr Power is <15 dB the receive signal is probably too weak to be useful. If the power is
>55 dB the receiving unit is probably being saturated.
6. Adjust Tx power of both units to obtain a fade margin (Corr Power) of 15–30 dB, as displayed by the Link
Monitor Statistics window. See Adjusting the Tx Power Level, page 76 and Performing Transmit and Receive
Tests, page 57.

Performing Simple Network Tests
To 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. A ferrite block is placed around the 10/100BaseT Ethernet cable
to prevent electromagnetic interference (EMI) from transferring from a unit to the Ethernet cable, and from
the Ethernet cable to the unit. The ferrite block is included with the contents of the shipping box. Install a
ferrite block when testing units, and ensure that a ferrite block is in place when units are installed in the field.
➧ To install the ferrite block
1. Remove the ferrite block from the plastic packaging.
2. Pull the clip and open the ferrite block. See
3. Place the Ethernet cable in the center of the open ferrite block. Locate the block approximately 4 cm
from the cable connector end that plugs into the unit’s Ethernet port. See
4. Close the ferrite block around the Ethernet cable, making sure that the block snaps together. See

4. Create some network traffic to test the wireless link. For example, use ping or ftp put and get to
transfer a large test files, in both directions, across the link. The Wire LED on the AWE indicates link file
transfer activity to the wired LAN. 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.

Install Units
APR 2001 Rev 03 29
Install Units
This 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.
• 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 the RSSI Test, page 59 and Performing Link Monitor Test (Normal Mode), page 54
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.
• Install ferrite blocks on all 10/100BaseT Ethernet cables at the end of the cable that plugs into the
unit. See Performing Simple Network Tests, page 25.
• 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 in the network plan, lock down and weatherproof all equipment
and connnections.
WARNING
All antennas must be professionally installed following accepted safety, grounding,
electrical, and civil engineering standards. An antenna (indoor or outdoor), dummy load,
or terminator must be connected to the antenna port of a unit before a unit is powered
up to avoid damaging the unit.
Installation
30 AWE 120-58 Installation & Configuration Guide
Point-to-Multipoint Installation
The procedure for installing a point-to-mulitpoint 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 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.
• 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 tranmit test. See Performing Transmit
and Receive Tests, page 57.
• 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.
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 54.
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!
Preventative Maintenance and Monitoring
APR 2001 Rev 03 31
Network Test Setup
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 133 for more information.
If you have SNMP application software, you can check unit operation remotely. See Appendix D: SNMP, page
133 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.

IP Filter Configuration
APR 2001 Rev 03 45
IP Filter Configuration
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. If an address is listed in the table, the
unit will pass data packets to other IP addresses. If it is not listed, the unit will not pass data packets.
When IP address filtering is enabled, all IP packet are sorted according to the following conditions:
1. If the source IP address is contained in one of the IP address lists, IP packets coming from the wire will
be forwarded to the air. If not, IP packets are dropped.
2. If the destination IP address is contained in one of the IP address lists, IP packets coming from the air
will be forwarded to the wire. If not, IP packets are dropped.
Each IP address filter is defined by a range and a base value. IP address filtering improves system security and
helps manage data throughput.

The general equipment setup is shown below. The specific setup depends on the test you want to run.
• To perform the Normal Mode (Link Monitor) test you need to connect a PC to either the base
station or a remote unit.
• To perform the Transmit Test or Receive Test you need at least one base station with PC, a remote
station with PC, and an RF link between units. See Establishing a Basic RF Link, page 21 for instructions
about establishing an RF link.
• To perform the RSSI test you need a PC for the unit that will transmit. The receiving unit does not
require a PC. You can also run this test with the Mode button.

Performing Link Monitor Test (Normal Mode)
The link monitor test can be run from either a base station or a remote unit that is set to Normal Mode. The
test operates in parallel with the message stream, so it consumes some of the link’s total data capacity. You
can control the ratio of test data to message data (and thereby control the amount of test data overhead) by
setting the link monitor period. See Setting the Link Monitor Period, page 61 for more information.
Note: Link monitor test stays in effect even if you power cycle or reboot units, so you must turn it off using
the Link Monitor Period (0 = OFF) setting.

Adjusting 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 128 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 128 kbps in each direction. A throttle level of 50 means
that 50 x 128 kbps will be passed. When throttling is disabled, the unit uses the maximum available bandwidth.
The default setting is to disable throttling.
➧ To enable throttling
1. 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.

Radio Module Configuration
The Radio Module Configuration menu is used to change several key parameters, including station type,
station rank, and security passwords. Because these settings can affect service, they are changed in three
progessive stages: new, current, and flash. (New and current are for temporary storage, while flash is for
long-term storage.) The general procedure for changing settings with the Radio Module Configuration menu
follows.
1. View the current Radio Module Configuration menu. See Viewing the Radio Module Configuration, page 65.
2. Select Config Test Minutes. To begin, enter a time of 15–20 minutes. See Setting Config Test
Minutes, page 67.
3. Select a parameter and, if necessary, change the value in the "New" column.
4. After making changes, select Reboot New RF Configuration and press Enter. The unit reboots
and the "New" settings become the "Current" settings of the unit. See Rebooting and Saving RF Module
Configurations, page 84.
5. If the unit operates as expected, you can save the current settings to "Flash". See Rebooting and Saving
RF Module Configurations, page 84.
If current settings do not operate as expected, do not save them to "Flash". Either change the current
settings or wait for the Config Test Minutes time period to expire. At expiry, the unit will
automatically reboot and revert to the last-saved flash memory settings. See Rebooting and Saving RF
Module Configurations, page 84.

Setting the Station Rank
Station 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. See Setting Dynamic Polling Level (Base
Station Only), page 80.
➧ To set the station rank
1. From the Main Menu, select Radio Module Configuration and press Enter. The Radio Module
Configuration menu is displayed.

70 AWE 120-58 Installation & Configuration Guide
Setting the Center Frequency
A 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 Frequencies
A 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.

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. If you wish, you can choose your center frequencies from these sample schemes.
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.

Setting Security Passwords
Passwords are always exchanged between units when they communicate with each other. A set of five
security passwords is assigned to each unit. The set of passwords must be exactly the same for all units in a
system. (A convenient, but non-secure option is to set all passwords to "0".) The more password levels you
use, the greater the security of your system. For example, using a set of five different passwords will result in
a highly secure system. All units in the same network must use the same set of security passwords.

Setting the Scrambling Code
To protect the privacy of a wireless link, units can scramble messages—the message content is rearranged so
that messages are difficult to read by unintended receivers. The scrambling code determines how messages
are scrambled by a unit. Only units with the same scrambling code as the originating unit can de-scramble and
read the message. The scrambling code can be 0-32 bits long. All units in the same wireless network must
have this setting set to the same value.

Setting the Acquisition Code
An 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.

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 81 for information about RF groups.) The diagram below expains the process.
Repeater Mode
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

Setting System Symmetry Type (Base Station Only)
System symmetry type fixes the priority of the base unit when it polls remotes. The default "asymmetric"
setting alots the base one time slot for each time a remote is polled—this setting is useful when the base is
the access point to a large network. The "symmetric" setting alots the base one time slot per polling cycle. A
symmetric system gives the base station the same polling priority as a remote unit.

Setting 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. If the remote doesn’t respond within the time period, the base
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.

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
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.

82 AWE 120-58 Installation & Configuration Guide
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)
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 charactersitics assigned to it (0 =
closed , 1–63 = open; same non-zero group number = communication, different non-zero group number =
no communication).

Because changes to radio module configuration settings can affect service in a wireless system, changes are
made in three progessive stages: new, current, and flash.
A reboot of a unit is required to save New settings as Current settings. If Current settings are valid (and do
not disrupt the system), they can be saved to Flash memory. If the changes disrupt the system, the original
configuration will be restored automatically when the Config Test Minutes period expires.
➧ To reboot a unit
1. From the Main Menu, select Radio Module Configuration and press Enter. The Radio Module
Configuration menu is displayed.
2. Select Reboot New RF configuration and press Enter. The unit reboots with the with new
settings and with the Config Test Minutes timeout period in effect. The new settings can be viewed in the
"Current" column of the Radio Module Configuration menu. The old, last-saved configuration remains
in Flash memory.
If the configuration is the one you want and the unit operates as intended, you can save the current
changes to "permanent" flash memory by selecting Save Current Config to Flash from the
Radio Module Configuration menu. When you save the current settings to "Flash" the new settings
overwrite the old flash memory settings.
New Intended configuration changes. Temporary memory storage.
Current Configuration actually running on the unit. Temporary memory storage.
Flash Configuration stored in FLASH memory. Long-term memory storage.

Allowing Remote Access and Configuration
One way to control remote access to a unit’s configuration menu is by restricting the type of link that can be
used to make remote configuration changes. The default setting is to allow remote configuration changes with
both wired and wireless links using telnet or SNMP. However, you can enable or disable the type of link
independently with two settings: Ethernet Access to Local Host and Wireless Access to Local Host.
Note: Data will pass as usual between both units. These two settings only restrict remote access to the unit’s
configuration menu, depending on the type of link that exists between the remote terminal and the
unit–wired or wireless. Also, you cannot "ping" a unit if the link is disabled.

Troubleshooting
Administrative Best Practices
By 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
31 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 92.
• 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.
Troubleshooting
106 AWE 120-58 Installation & Configuration Guide
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.

Appendix A: Planning Your Wireless Link
To 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 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.
Appendix A: Planning Your Wireless Link
112 AWE 120-58 Installation & Configuration Guide
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.
More information about antennas is provided in Antenna Basics, page 118.
WARNING
Correct antenna installation is critical to the safe operation and performance of your
system. Antennas should always be professionally installed.
Determining Unit Configuration Settings
APR 2001 Rev 03 113
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
Appendix A: Planning Your Wireless Link
114 AWE 120-58 Installation & Configuration Guide
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.
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 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
Formula: System Gain = Transmission Power - Receiver Sensitivity @ 10-6 BER
Variables: Tx Power = 20 dBm
Receiver Sensitivity = –80 dBm (receiver sensitivity @ 10-6 BER)
Calculation: 20dBm – (–80) dBm = 100 dB
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.
Variable Description
Calculating a Link Budget
APR 2001 Rev 03 115
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:
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
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

The maximum
Fresnel Radius

path must be kept
clear of
obstructions.
Appendix A: Planning Your Wireless Link
116 AWE 120-58 Installation & Configuration Guide
For the 5.8 GHz band, the approximate Fresnel Radius is calculated as follows.
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.
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.
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 114 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.
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 LDF4.5-50

Link Budget Example
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.
Formulas: System Gain + Antenna Gain ≥ Propagation Loss + Desired Fade Margin +
Cable Losses + Connector Losses
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 = 20 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 = 20 - (–80) = 100 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 = 100 + 54 – 128 – 3.2 – 2 = 20.8 dB
Analysis: A goal of Actual Fade Margin ≥ 15 dB is achieved.

118 AWE 120-58 Installation & Configuration Guide
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
Antenna Basics
APR 2001 Rev 03 119
Implementation Considerations
Some 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 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
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
Parameter Description

120 AWE 120-58 Installation & Configuration Guide
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.
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?

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
• 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
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
technicial
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, page 113
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 115 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 Link
122 AWE 120-58 Installation & Configuration Guide
Minimal Clearance Above Obstructions
For the AWE 120-58, the absolute minimum clearance above obstructions requirements are as follows (in
meters):
@ 5.8 GHz
Some 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 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.
• 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.

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 uptilit or downtilt. Contact your distributor for antenna and installation
assistance when co-locating units.

Appendix D: SNMP
About SNMP MIB
Three 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 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
Appendix D: SNMP
134 AWE 120-58 Installation & Configuration Guide
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.
Using SNMP
Refer to the documentation provided with your SNMP application software for instructions about using
SNMP. The procedure for changing a unit’s configuration with SNMP is described below.
To change a configuration setting with SNMP
1. Change the parameter to a new value using the appropriate SNMP command.
2. Reboot the unit with the new configuration using the rebootNewRfConfig node command. See System
Commands, page 147.
3. Save the new configuration to the unit’s flash memory using the saveConfToFlash node command. See
System Commands, page 147.

Appendix G: 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.)
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\images
This directory is an example only.
Appendix G: Upgrading Software
154 AWE 120-58 Installation & Configuration Guide
6. Type ftp <IP address> and press Enter where the IP address is the address of the AWE unit. 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 92). The ftp> prompt appears.
9. After the ftp prompt, type the following "put" command.
Note: Leave a single space after "put."

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 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 97.
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 133.
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
39.

Glossary
A
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. The problem does not become
evident until the spring when leaves appear.
acquisition code
To minimize the effects of interference, all units in a system use the same acquisition
code so the receivers can distinguish the desired signal from other interfering signals.
agent
In an SNMP context, the agent runs on each unit. An agent accepts configuration
commands from the manager and collects network and terminal information specified in
the MIB.
antenna
A device which accepts electromagnetic energy from a circuit or wire and radiates it into
space rather than confining it.
antenna gain
Gain of the antenna over a dipole (dBd) or isotropic (dBi).
• 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 more
compressed signal.
ARP
Address Resolution Protocol. A low-level protocol that maps IP addresses to Ethernet
addresses. An ARP request is sent out to the network along with an IP address. The node
with the address responds to the request with a hardware address so the transmission
can take place.
attenuation
Any loss in signal strength, due to resistance, absorption, capacitance or any
characteristic of the medium or design of the system.
Glossary
158 AWE 120-58 Installation & Configuration Guide
B
base station
The central control unit of the wireless network. A base station polls remote units and
controls how traffic is routed to remotes. The base usually connects to a major access
point of main wired network.
beamwidth
The beamwidth of an antenna describes how a signal spreads out from the antenna as
well as 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.
BER
Bit Error Rate. A percentage of bits per million, showing the number of bits in error
compared to the data bits actually sent.
blocking
Blocking is an operating mode where the radio receives only. Unblocked is the normal
operating mode.
C
cable loss
The signal loss experienced as it passes through the coax cable. Expressed in dB.
channel
The part of the spectrum band occupied by a radio signal, usually measured in
kilohertz (kHz).
closed system
A system where remotes cannot communicate directly with each other. They can only
communicate with each other via a base station.
coaxial cable
A type of wire where the inner conductor is surrounded by an outer conductor. The
outer conductor serves as an electrical shield.
co-location
Refers to placing base stations or units in the same location. In this situation, base
stations or units can interfer with each other unless steps are taken to isolate the
systems from one another (such as aligning antennas or using different channels).
collision
The situation that exists when two users try to send a signal over the same medium at
the same time and the signal uses the same frequencies.
configuration menus
Menus that allow the viewing and setting of unit parameters.
APR 2001 Rev 03 159
contentionless polling
A form of dynamic polling that ignores idle remote stations. The number of polls that an
idle remote is ignored can be set to maximize polling to active stations.
Cross-Polarization Discrimination
See XPD.
D
dB
Decibel. A relative measure of power used to specify power gains and losses. The
difference in power P1 and P2 expressed in dB is
DB9
A D-shaped connector with 9 pins.
dBd
dBd is antenna gain referenced over a half-wave dipole which is an antenna that has a
donut shaped radiation pattern. Gain of a Standard Dipole = 2.14 dBi.
dBi
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.
dBm
A power measurement referenced to one milliwatt. This is an absolute measure of gain.
diffraction
Diffraction occurs when a radio signal reflects or bounces off of a solid object. The level
of diffraction could lead to connectivity problems if the remaining signal level is too low.
Two types of diffraction are shadowing and multipath.
downtilt
Some antennas have either an associated downtilt or an uptilt. The tilt further focuses the
signal either downward or upward with respect to the horizon. A tilt may be either
electrically built into the antenna or achieved mechanically with the mounting gear. An
downtilt or uptilt may be required when there is a significant deviation between the
elevation of the remote site(s) and the base site.
DSSS
Direct sequence spread spectrum. A method of expanding the radio signal over a broad
portion of the radio band.
dynamic polling (DP)
A polling protocol in which idle units are not polled as frequently as active units. Since
less time is spent polling idle remotes, there are more available resources for active units
and overhead is reduced.
dB 10 P1P2⁄()log×=
Glossary
160 AWE 120-58 Installation & Configuration Guide
dynamic time allocation (DTA)
A process for determining how active a remote unit is. A unit is allowed a brief time to
respond to a poll before the remote is considered idle.
E
EEPROM
Electrically Erasable, Programable Read Only Memory: non-volatile memory.
EIRP
Effective Isotropically Radiated Power. 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
size of the antenna and the losses incurred in the antenna cable. To remain license
exempt, the EIRP must remain under 4 watts or 36 dBm in Canada and the United States
for point-to-multipoint applications. In Europe, this value is reduced to 100 mW or to
20 dBm.
Note: EIRP = Power out of unit – Power lost in cable + Gain in power from antenna
ERP
Effective Radiated Power. The power radiating from an antenna, taking into account the
output power from the transmitter, connector losses, cable losses and the antenna gain.
ETSI
European Telecommunications Standards Institute.
F
fade margin
The amount that the system gain plus the total antenna gain exceeds the path loss is
called the fade margin. The fade margin is calculated as the number of dB that the
received signal strength exceeds the minimum receiver sensitivity.
filtering
Filtering limits certain data packets or IP addresses from being passed by a unit.
FHSS
Frequency hopping spread spectrum. A method of spreading a narrowband signal across a
wide radio band by "hopping" the signal as a function of time.
Flash memory
A type of electrically erasable non-volatile memory that can easily be erased without
removal from a unit.
fresnel zone
The zone around the line of sight between two antennas. It consists of one of a
(theoretically infinite) number of a concentric ellipsoids of revolution that define volumes
in the radiation pattern of a (usually) circular aperture.
APR 2001 Rev 03 161
front to back ratio (F/B)
Directional antennas focus the signal in a forward path. This is 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.
ftp
File transfer protocol. A network utility program for moving files between nodes.
G
gain
The ability of a device to amplify a signal. Gain is the ratio of output power divided by
input power, usually expressed in decibels (dB). Gain can also be measured as an absolute
value, referenced to an input signal of 1 mW (dBm). For antennas, gain measures the
ability of an antenna to focus a signal and is expressed in dBd (half-wave dipole reference)
or dBi (isotrophic raditator reference).
gateway
The access point between one LAN and another LAN that would otherwise be
incompatible with each other. It is usually a hardware device that steers communication
between networks while performing code and protocol conversions.
I
IEEE
Institute of Electrical and Electronics Engineers.
image
An image is a collection of configurations or settings for a particular device. With the
unit, the System Image File contains a collection of configurations that are used when the
unit is rebooted.
interference
Any signal that tends to hamper the normal reception of a desired signal. Equivalent to
jamming except considered non-hostile in origin.
IP Address
A number assigned to a network node, domain or subdivision. The number consists of
four numbers—the first two numbers identify the network and subnetwork and the last
two numbers identify unique nodes in the network.
ISM
Industrial, Scientific, and Medical. It consists of three license-exempt radio bands in
North America and some European countries. It is also referred to as part 15.247 in the
FCC regulation that defines the parameters for use of the ISM band in the U.S., including
power outputs, spread-spectrum, and noninterference.

L
link monitor
A AWE utility that sends known data over an active system to test the reliability of the RF
link. The link monitor information is overhead, that is, it reduces the amount of available
payload for message data.
LOS (Line of Sight)
A clear, visual line of sight between antennas. When standing at the antenna position, you
must be able to see the remote antenna. An elliptical pattern around the line of site,
known as the Fresnel Zone, must be kept free of obstructions
M
MAC address
Media Access Control address. Alphanumeric characters that uniquely identify a
network-connected device. To prevent unneccesary traffic over a radio channel, units
automatically learn the MAC addresses of equipment connected to the local Ethernet
segment and do not transmit over the radio channel if the destination is local. A packet
entering a subscriber unit from the radio port is not sent to the Ethernet port unless the
destination MAC address has been learned from packets entering the Ethernet port.
manager
When used in SNMP, this element is installed on the network’s host computer and is
controlled by the network administrator. From the host, the manager configures agents
or polls agents for information.
MIB
Management Information Block. The MIB is a database which is accessed by a specific set
of commands that you can execute 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.
multipath interference
When a radio signal is transmitted, it can reflect off of physical objects in the
environment and take various paths to the receiver. As a result, the signal can arrive at a
receiver at different times, confuse the receiver, and cause bit errors and processing
delays.
O
OID nodes
Object Identifier Nodes. These are the individual nodes in a MIB. See SNMP and MIB.
open system
A system where remote units can communicate directly with each other and with the
base station.
APR 2001 Rev 03 163
overhead
Anything that reduces the payload capacity of a system is overhead, even if it serves a
useful function. The link monitor data is used to determine transmission statistics, but it
reduces the message carrying capacity of a wireless link and is considered overhead.
P
path loss
The total loss from one end of the path to the other. This includes propagation losses,
cable losses and any other losses that impact the system performance.
PN
Pseudo-random noise. A code used to change a narrowband signal into a spread
spectrum signal.
polarization
The orientation of the radiating element of an antenna with respect to earth. The
polarizaiton of antennas is usually described as being vertical, horizontal or circular.
point-to-multipoint
A wireless system where one base unit communicates with many remote units. The base
unit polls all the remotes and data passes between units to complete the network.
point-to-point
The simplest wireless system consisting of a base and one remote.
polling
The base unit in a AWE point-to-multipoint system handles multiple remotes by polling
each one sequentially. When a base polls a remote, data exchange between that remote
and the base takes place. The remote cannot exchange information with the base until it
is polled again.
propagation loss
The signal loss experienced as it travels through the air. Expressed in dB.
R
RF
Radio Frequency. A system of communication using electromagnetic waves propagated
through space. Because of varying characteristics, radio waves of different lengths are
used for different purposes and are usually identified by their frequency.
remote unit
A unit that can communicate with a base station or other remote units. A remote unit
forms a wireless link between a network segment and a base station.
repeater base
A repeater base rebroadcasts packets received from a remote unit to other remote
units. Remote units that cannot see each other (do not have LOS) can communicate
through a repeater base.

other factors about the signals to be used, as well as single-ended, differential, multi-drop
operation.
RSSI
Received Signal Strength Indicator. Strength of received signal expressed in dB. The AWE
unit measures RSSI as a fade margin value.
S
scrambling code
A code used to scramble messages, so that only units with the same scrambling can read
the messages.
sensitivity
The minimum signal strength required for usable performance by a unit. Expressed in
dBm.
shadowing
Shadowing is a form of diffraction that is typically caused when antennas are mounted
too close to a structure and 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 when mounting antenna equipment to a structure.
SNMP
Simple Network Management Protocol. A protocol you can use to remotely manage a
network element by polling, setting terminal values, and monitoring network statistics
and events. It is the de facto internet work management standard, designed to provide a
mechanism for the exchange of management information in a TCP/IP-based Internet
environment.
spread spectrum (SS)
Any of a group of modulation formats in which an RF bandwidth much wider than signal
bandwidth is used to transmit information, resulting in a greater immunity to noise
interference.
system gain
The maximum path loss that the system can support for usable data transmission.
system image file
The AWE unit uses system image files to store system configuration settings. The default
system image file is called “factory-image” and is used when the AWE is first powered up.
T
telnet
An Internet communications protocol that enables a computer to function as a terminal
working on a remote computer. A computer with a network connection to a AWE unit
can use telnet to access its configuration menus.
APR 2001 Rev 03 165
throttling
Throttling limits the amount of data that a remote station passes. This feature is used to
improve overall system performance by adjusting the throughput of a unit to match the
throughput of other devices in the network.
U
uptilt
See downtilt.
V
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 watt output with an antenna VSWR of 1.5:1, the
reflected power will be 160 milliwatts.
W
W-OFDM
Wide-band orthoganal frequency division multiplexing. A method patented by Wi-LAN
that divides a channel into several sub-channels, spreading the signal over the subchannels
and correcting errors without having to retransmit. W-OFDM permits several
independent channels to operate within the same band, enabling multipoint networks and
point-to-point systems to be overlaid in the same frequency band.
X
XPD (Cross-Polarization Discrimination)
Antennas have an associated polarity, which is the orientation of the radiating element
with respect to earth. Antennas are usually described as being vertically, horizontally or
circularly polarized. The polarity of all antennas used in a system must be the same. XPD
specifies the amount of signal isolation achieved when the receiving element is
perpendicular to the radiating element. This can be advantageous when co-locating radio
systems.
