AWE 120-24 Installation & Configuration Guide
Description
Features
The AWE 120-24 is a wireless Ethernet bridge that provides high-speed, wireless connectivity at a fraction of
the cost of wired solutions. It operates over the 2.4 – 2.48350 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 12024 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. Contentionless polling
ensures efficient access to remote data networks.
• Is self-contained and easy to use. Simply connect a AWE 120-24 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 RS232 management enable users to manage, configure and monitor their wireless network with
ease.
About Spread Spectrum
The FCC allocates three frequency bands (called the ISM bands) to a radio technique known as spread
spectrum communication. The bands are located at 900MHz, 2.4 GHz, and 5.7 GHz (shown in the following
illustration). The AWE 120-24 operates with spread spectrum technology over the
2.4 – 2.4835 GHz band.

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 (a 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, transmitter power is
limited, and a non-standard antenna connector is used.
About AWE Units
AWE units can function as base stations, remote units or repeater bases.
Base Station: At least one unit in your wireless network must be a base station. A base station acts as the
central control unit of the wireless network.The base station polls all remote units and controls how traffic is
routed to and from remotes. The base usually connects to a major access point of the wired network. The
antenna of the base station must be capable of transmitting and receiving radio signals to and from all the
remote units in a system. If remotes are spread over a large area, an omni-directional antenna is usually
required. See Configuring a Base Station, page 15 for information about setting up a base station.
AWE 120-24 Installation & Configuration Guide
Some System Applications
Remote Units: Remote units receive and transmit wireless data to the base station.You need at least one
remote unit for each wireless link. Remotes can limit the amount of data passed by the remote (a function
called throttling), and they can filter data packets based on their IP address. 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 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. The repeater uses a method called "store and forward" to receive data from the
orignating remote and to pass data to the destination remote. See Setting a Base to Repeater Mode (Base
Station Only), page 79 for more information.
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 120-24 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.

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 113 for
more information.

Some System Applications
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.

Description
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.

4 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 ability of the link to carry test data
•
Perform a simple network test
Establishing a Basic RF Link
This test ensures that a basic RF link exists between a base station and a remote unit.
! Important
The quality of your digital data transmission depends greatly on the quality of your RF
link. Always try to establish a high-quality RF link first. A high-quality RF link will
result in high-quality data transmissions and a low BER. A low-quality RF link will result
in low-quality data transmissions and a high bit error rate (BER). Digital data can always
be sent across a high-quality RF link. If the RF link is of poor quality, data either cannot
be sent at all or will contain too many errors to be useful..
Tip: Configure one unit as a base station, then use it to test all the remote units.
➧ To establish a basic RF link
1. Ensure that one unit is configured to a base station, select a center frequency and set the test minutes.
See Configuring a Base Station, page 15.
2. Ensure that the other unit(s) are configured as remote units and 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. For directional antennas, point antennas toward each other. For a dipole antenna, orient the
antenna vertically.

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.
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
Green (remote station)
Stations are configured incorrectly, and the remote station is
receiving packets to which it cannot respond
Off
Nothing is being received (by the remote) or transmitted (from the
base)
Note: If antennas are placed too close together (< 2 m), the strong transmit signal can saturate the receiving
unit. Fine-tune antennas by changing antenna orientations until the Air LED is orange.
Next, you will test the link’s basic ability to carry data.

Installation
5 Install Units
This section provides some guidelines about installing units in the field.
•
Install the units at locations identified in the network plan. Some units will simply sit on a table or
desk and do not require any special antenna work. Other units must be installed inside
communication cabinets or racks and will require professional antenna installation.
CAUTION
Never operate a unit without an antenna, dummy load, or terminator
connected to the antenna port.
Operating a unit without an antenna, dummy load, or terminator connected
to the antenna port can permanently damage a unit.
WARNING
Antennas must be professionally installed following accepted safety,
grounding, electrical, and civil engineering standards.
26
•
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 57 and Performing Link Monitor Test (Normal Mode), page 52
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 in the network plan, lock down and weatherproof all equipment
and connnections.

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 55.
•
Observe the BER and fade margin of the second sector radio. Look for changes to determine if the
first sector is interfering with the second sector.
•
Repeat the tests for all sector/pair combinations.
6 Test Network
Run the link monitor test, transmit test and network tests such as ping and ftp file transfers to verify
operation when the units are installed in the field. See Performing Link Monitor Test (Normal Mode), page 52.
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
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 135 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
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.

RF Station Configuration
RF Station Conﬁguration
The RF Station Configuration menu enables you to choose the operating mode, run some tests and optimize
the RF link. Four tests can be run from this menu: link monitor test, transmit test, receive test and RSSI test.
You can optimize a link by setting the maximum remote distance to a remote and by controlling the rate of
data throughput (throttling).You can also block a unit so that it cannot pass any data.

General Equipment Setup for Performing RF Tests
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 20 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 59 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 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 50 means
that 50 x 64 kbps will be passed. When throttling is disabled, the unit uses the maximum available bandwidth.
The default setting is to disable throttling.

RF Station Configuration
Setting Tx Power Automatically (Remote Station Only)
Link Monitor/Output Power can be used to adjust a remote unit’s Tx power automatically. Three modes of
operation are available: Normal mode is used to run Link Monitor normally. Link Monitor tests the link and
collects statistical information about link operation, which can be viewed with the Link Statistics screen.
Automatic Output Power runs Link Monitor through one "cycle" and automatically adjusts Tx power based on
measurements taken during that cycle. Power is automatically reduced by the unit if Tx power is too high and
is increased if it is too low. Dynamic Output Power 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) required by Link Monitor is set with Link Monitor Period. (See Setting the Link Monitor Period,
page 59).
How Automatic Output Power Adjustment Works
Link Monitor tests a link by sending test packets and measuring the link’s performance (in terms of BER and
power). The results of the test can be used to automatically adjust Tx power. Automatic power level
adjustment is explained below.
The maximum Tx power output (factory-set power ceiling) of a unit is set at factory and cannot be changed with
configuation menus (for more information see Unit Identification, page 34). 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.

Base Tx PowerLevel
Noise Floor
The noise floor is the power level below which signal quality deteriorates rapidly due to random radio
interference causing the link to not function properly. Base Tx Power level is the starting power level or
"base" from which the adjustment is made. The operating Tx Power level is the sum of the base power level and
the signal margin (fade margin)—the signal margin is added to the Tx base power level and moves with it. Both
the base power level and the signal margin can be adjusted to reach the operating power level.
When a unit adjusts the power level, it begins at the base power level and runs Link Monitor. If no bit errors
occur and the power level is satisfactory, the unit automatically drops the Tx power level by one dB and runs
JUL 2001 Rev 03

Configuration
Link Monitor again. If no bit errors occur again and power level is adequate, it once again drops the Tx power
level by a dB and runs Link Monitor. This process repeats until a power level occurs where no bit errors
occur and power level is satisfactory. 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 methods of automatic power level adjustment are available: automatic and dynamic.
Automatic Power Output: Power is monitored and automatically adjusted once when the unit is
powered up or rebooted.
Dynamic Output Power: 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 59).
Note: 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.

Setting Signal Margin (Remote Station Only)
The signal margin is the output transmit power (measured in dB) desired for a remote unit with respect to
the base station’s receive sensitivity threshold). This value is used by Output Power Control test modes to
set the transmit power.
For example, if set to 10 dB, an Output Power Control test mode will attempt to adjust the output transmit
power to a level at which the received signal at the base station is 10 dB greater than receiver sensitivity
threshold.

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 69.
2. Select Config Test Minutes. To begin, enter a time of 15–20 minutes. See Setting Config Test
Minutes, page 71.
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 86.
5. If the unit operates as expected, you can save the current settings to "Flash". See Rebooting and Saving
RF Module Configurations, page 86.
If current settings do not operate as expected, do not save them to "Flash". 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 86.

Setting Conﬁg Test Minutes
When changing Radio Module Configuration settings, you may enter settings that cause a unit or system to
not function as expected. If this happens, you can return to the last-saved settings if you first set the Config Test
Minutes test period. When this test period expires, the unit automatically reboots and returns to its last-saved
flash memory settings. The time period can be fixed from 1 to 120 minutes.
Tip: To begin, enter a time period of 30 minutes. If the time period is too short, you will not have enough
time to make configuration changes and save them to flash ROM. If the time period is long, you will have to
wait a long time before the unit automatically reboots and restores the settings to the original flash ROM
state.

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 82.

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.

Adjusting the Tx Power Level
Tx Power Level Adjust enables you to reduce the transmit power output level by up to 31 dB. For example,
selecting a value of 0 sets the transmit power to maximum power, while selecting a value of –31 sets the
transmit power to 31 dB below maximum power. The value is the intial Tx power level and is reset
automatically when automatic power level adjustment is performed. See Setting Tx Power Automatically (Remote

Setting a Base to Repeater Mode (Base Station Only)
When repeater mode is enabled at a base station, 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
83 for information about RF groups.) The following diagram expains the process.

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.

Configuration
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.

Radio Module Configuration
Setting Remote Unit RF Group
The RF Group setting enables you to determine which units in a system can communicate with each other.
For example, in a system consisting of a base station and associated remotes, you can: 1) assign units to
different groups so that only members of the same group can communicate with each other and the base (an
open system); 2) isolate remotes so they cannot talk to other remotes, but can talk only to the base (a closed
system); 3) assign remote units to groups and configure the base station as a repeater (a closed system); and
4) combine closed units with open units in the same system. These configurations are explained below.
Remote units with the same RF group number (RF Group = 1– 63) can communicate directly with each other
and with the base station (if there is a line-of-sight RF path between units and base station Repeater Mode =
off.) An example is a company where the Human Resources department needs direct access to the Payroll
department, but the two departments must be isolated from other departments. Since HR and Payroll are in
the same RF group 14, they can talk directly to each other, but they cannot talk directly to other groups such
as R&D, which belongs to RF Group 20.
Example 1: Open System

Mode = off
Base
Remote
RF Group = 20
R&D
Remote
RF Group = n
n = 1 – 63
RF Group = 14
Human Resources
Remote
RF Group = 14
Payroll
Remote units configured as RF Group = 0 are independent, closed units. Closed units cannot talk directly to
each other, they can only talk directly to the base station. This setup acts to isolate remote units and the
associated LANs from each other. Example 2 shows a situation where independent companies are connected
wirelessly to a single base station and communication between the companies is prevented.

Configuration
A repeater is used to bypass obstacles that block the RF path (for example, a mountain). When a base station
is set to repeater mode (Repeater Mode = on), it can pass data from remotes in an RF group to other
remotes in the same group. A system with a repeater is a closed system. Example 3 shows a repeater with
four remotes. All the remotes are in the same RF Group 4, so they can talk to each other via the repeater
base.

No direct communcation

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.

Rebooting and Saving RF Module Conﬁgurations
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.
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.
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.

Assigning Community Names
Community names can be used to control SNMP access to the AWE unit. Community Name 1 has read only
access, and Community Name 2 has both read and write access. An SNMP manager can access and configure
any AWE unit on the network as long as the unit has the correct community names and remote access is
enabled (see Allowing Remote Access and Configuration, page 96).
CAUTION
Default community names are presented in all Installation and
Configuration guides distributed by Wi-LAN. It is the responsibility of the
customer to ensure that default community names are changed to unique
names at installation. Record all community name changes.

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 restrict remote access to the unit’s
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
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 94.
•
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
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 wireless ethernet bridge.

AWE 120-24 Installation & Configuration Guide
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

radio path to some remotes.

Appendix A: Planning Your Wireless Link
Measure the Distance Between Units
Use a mapping method or GPS (global positioning system) to measure the distance between the base station
and each remote, and check the radio path to identify any obstructions in the site 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 antenna and the remote unit antennas.
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
If you plan to install a unit indoors, on-site testing is advised because all interiors are unique.You need to
consider several factors.
•
Ensure a clear line-of-sight radio path is available between each remote and its base station.
•
Ensure that Fresnel zone clearances are met. Identify obstructions that could degrade link
performance now and in the future.
•
Obtain permission from building owners if you intend to install the antenna on a rooftop
•
Obtain 24-hour access to antennas, cables and equipment
•
Determine antenna mounting positions: the final position should be selected to enable physical
shielding of the antenna at the back and sides from radio interference in the ISM band.
•
Consider potential wind load and ice loading impact on the antenna
•
Be aware of possible multipath effects: installing an antenna too close to reflective surfaces can cause
signal problems.
•
Check local regulatory restrictions, such as height, on antenna mast usage in the identified location
•
Ensure that your antenna is properly grounded and installed according to local electrical codes.
•
Determine transmission cable lengths and plan cable routes. Minimize the length of the coaxial cable
because the longer the cable, the greater the cable losses.
•
Calculate the fade margin—a minimum 15 dB fade margin is required to ensure the reliability of your
wireless link.
•
Determine Ethernet cable lengths and plan cable routes.
WARNING
Correct antenna installation is critical to the safe operation and
performance of your system. Antennas should always be professionally
installed.
More information about antennas is provided in Antenna Basics, page 120.

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

Appendix A: Planning Your Wireless Link
Variable
Description
Fresnel Radius
Distance around line-of-sight that must be clear of obstacles
Cable Loss
Signal loss experienced as it passes through the coaxial cable, expressed in dB
Path Loss
Total loss from one end of the path to the other. Includes propagation losses,
cable losses and any other losses that impact the system performance
Each variable is described below.
System Gain
The system gain of a radio system is the difference between the transmitted power and a receiver’s sensitivity
threshold. The system gain of the AWE 120-24 is calculated as follows.
Formula:
System Gain = Transmission Power - Receiver Sensitivity @ 10-6 BER
Variables:
Tx Power = 20 dBm
Receiver Sensitivity = –81 dBm (receiver sensitivity @ 10-6 BER)
Calculation:
20dBm – (–81) dBm = 101 dB
To ensure reliable communications, the system gain plus all antenna gains must be greater than the sum of all
losses. For a reliable link,Wi-LAN recommends that the system gain plus all antenna gains be greater than the
sum of all losses by 15 dB. This amount is the fade margin.
EIRP (Effective Isotropically Radiated Power)
EIRP is the power that radiates from an antenna, taking into account the output power from the transmitter,
the connector and cable losses, and the antenna gain. Unlike the Tx output power of the devices, EIRP takes
account of antenna gain and cable losses. Antennas use directional gain to increase the effective radiated
power. Losses such as cable losses reduce the effective radiated power.
You calculate the EIRP as follows.
Formula:
EIRP = Tx Power (dBm) - Cable Losses (dB) - Connector Losses (dB) + Antenna Gain (dBi)
Note:
The FCC regulatory body has set the EIRP limit to +36 dBm for point-to-multipoint
applications per FCC 15.247(b)(3)(i).
For point-to-point applications, the FCC EIRP can be 3 dB higher than +36 dBm for every
1 dB less Tx power below 30 dBm.
Industry Canada specifies the EIRP limit to ≤+36 dBm for point-to-multipoint as per
RSS-139 Annex B.
In accordance with ETS 300-328 for 2.4 GHz RLANs, the maximum EIRP shall not exceed
+20 dBm, with a maximum SPD (Spectral Power Density) not exceeding +10 dBm/MHz.
Confirmation is required with the relevant European national radio communications local
authority for deviations from this specification.
116
AWE 120-24 Installation & Configuration Guide
Calculating a Link Budget
Antenna Gain
To ensure the best range and interference suppression, the external antenna should be directional, focusing
the radio energy in one direction (toward the other end of the link) rather than onmi-directional. Use of a
directional antenna also reduces interference from other systems operating at the same frequency.
Note: In some situations, you may want to use an omni-directional antenna in your system design. For
example, you would use an omni-directional antenna for a base station with remote sites situated in a
360º path around it.
When you select an antenna from the list, pay particular attention to the gain specification. When you select
an antenna for a remote station, select an antenna with a gain that provides at least 15 dB fade margin.
Antenna gain is specified in either dBi or dBd. When an antenna is specified in dBd, add 2.14 dB to the value
to convert it to dBi.
Propagation Loss
Propagation loss is the attenuation (reduction) in RF signal energy as it travels through space. In most wireless
systems, losses through space are the major contributor to signal attenuation. When you know the intended
installation locations of the base and remote stations, determine the physical line of sight distance and then
calculate the RF attenuation as follows:
Formula:
Attenuation (dB) for 2.4 GHz band = 100 dB + 20log(dkm)
where:
dkm = Distance in Kilometers
100 dB = Pathloss Constant in the 2.4 GHz band
Fresnel Zone
It is essential that you locate your antennas at maximum above-ground height to ensure that all ground-based
obstructions are cleared from the Line of Sight path and the Fresnel Zone.
The Fresnel Zone is the expansion of the RF signal radio angles in the vertical plane near the middle of the RF
path.

For the 2.4 GHz band, the approximate is Fresnel Radius calculated as follows.
Fresnel Radius (meters) = 3.4 d km + ( d km ⁄ 8.12 )
Formula:
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 120-24 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 2.4 GHz.
Cable Type

0.128
0.073
0.053
Note: When you calculate path loss, you will add 1dB at each end of the link to compensate for connector
losses in addition to the cable loss value.
Path Loss
Path loss describes the total RF attenuation throughout the system from Tx antenna to Rx antenna. This
includes the losses as the RF signal travels through space plus Tx and Rx cable loss, and Tx and Rx connector
loss. Use the following formula to calculate path loss.
Formula:
Path Loss = Tx and Rx Cable Loss + Tx and Rx Connector Loss + Propagation Loss
Once you know the path loss, you can compare the value to the system gain value. If the system gain value is
greater than the path loss, the link is feasible. See System Gain, page 116 for more information about system
gain.
Fade Margin
Fade margin is the amount by which the system gain plus the total antenna gain exceeds the path loss.
Formula:
Total antenna gain = Tx Antenna Gain + Rx Antenna Gain
As calculated, the fade margin is the number of dB that the received signal strength exceeds the minimum
receiver sensitivity.You require some level of fade margin for any wireless system to compensate for RF path
fading due to weather conditions or multipath interference.
The Wi-LAN recommended fade margin for the AWE 120-24 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.

System Gain + Antenna Gain ≥ Propagation Loss + Desired Fade Margin +
Cable Losses + Connector Losses
Formulas:
or
Actual Fade Margin ≥ System Gain + Antenna Gain – Propagation Loss

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 = –81 dBm
Tx Antenna Gain = 21 dBi
Rx Antenna Gain = 21 dBi
Propagation Loss for desired range of 10km = 100 + 20 x log(10) = 120 dB
Tx Cable Losses (5m LMR400) = 5 * 0.22 = 1.1 dB
Rx Cable Losses (5m LMR 400)= 5 * 0.22 = 1.1 dB
Tx Connector Losses = 1 dB
Rx Connector Losses = 1 dB
Variable
Calculations:
System Gain = 20 - (-81) = 101 dB
Antenna Gains = 21 + 21 = 42 dBi
Cable Losses = 1.1 + 1.1 = 2.2 dB
Connector Losses = 1 + 1 = 2 dB
Actual Fade
Margin
Calculation:
Actual Fade Margin = 101 + 42 – 120 – 2.2 – 2 = 18.8 dB
Analysis:
A goal of Actual Fade Margin ≥ 15 dB is achieved.
The values for cable and connector losses in this example are only for illustration.You will need to work these
out for your specific installations.

Antenna Basics
Antennas focus and absorb radio energy in specific directions, depending on their design. AWE 120-24
antennas must be tuned to 2.40000 – 2.48350 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
120
AWE 120-24 Installation & Configuration Guide
Antenna Basics
Parameter
Description
XPD
• Polarity and Cross-Polarization Discrimination (XPD)
• Antennas have an associated polarity, which is the orientation of the radiating
element with respect to earth
• Antennas are usually described as vertical, horizontal, or circularly polarized. The
polarity of all antennas used in a system must be the same
• Cross-Polarization Discrimination specifies the signal isolation achieved when the
receiving element is perpendicular to the radiating element. Can be advantageous
when co-locating radio systems
VSWR
• Voltage standing wave ratio
• VSWR is the voltage ratio of minimum to maximum across a transmission line
• A VSWR of 2.0:1 or less in an antenna is considered effective. Most antennas have a
VSWR of 1.5:1
• For example, when using a radio with a 4 W output with an antenna VSWR of 1.5:1,
the reflected power will be 160 mW
Implementation Considerations
Some key items to consider when selecting and installing antennas for your wireless network follow.
Item
Description
Absorption
• Antennas mounted too close to “soft” objects, such as trees, may experience a
reduction in signal strength due to absorption
• Absorption is most often encountered in applications installed during the fall or
winter months, and the problem does not become evident until the spring
Diffraction
• Diffraction occurs when a radio signal reflects or bounces off of a solid object.
• Level of diffraction could lead to connectivity problems if the remaining signal level is
too low
• Two types of diffraction are shadowing and multipath
Shadowing
• Shadowing is a form of diffraction that is typically caused when antennas are mounted
too close to a structure and they lose a portion of the signal lobe due to reflection
The receive antenna is in a shadowed area
• To minimize shadowing, ensure that there is adequate height above structures when
mounting antenna equipment
Multipath
Interference
• Multipath is a form of diffraction in which the reflected signal arrives at the receiver
at different times which confuses the receiver
• Multipath may be interpreted as interference by the receive antenna and can result in
bit errors and processing delays

Selecting Antennas
There are several factors to consider when selecting 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?

Installing Antennas
WARNING
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.
JUL 2001 Rev 03
125
Appendix A: Planning Your Wireless Link
•
The coaxial cable is connected to the antenna and to the Antenna port on both sides of the link (base
and remote stations).
•
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 Wi-LAN Technical Assistance Center 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 120-24 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

Wi-LAN Object Identiﬁer Nodes
The AWE 120-24 uses SNMP version 1, which is MIB 2 compliant. All OID (Object Identifier) nodes in the
120-24 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.

System Commands
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 148.
3. Save the new configuration to the unit’s flash memory using the saveConfToFlash node
command. See System Commands, page 148.

AWE 120-24 Installation & Configuration Guide
Appendix G: Upgrading Software
If necessary, you can upgrade the software of a AWE 120-24. 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
Contact the Wi-LAN Technical Assistance Center (TAC) to acquire new image files. TAC can help determine
what files you require and the most convenient way to deliver it to you. See Customer Support Contacts, page
x.
Downloading Image Software
1. Obtain the new image files. (Image files may be delivered on floppy diskette, CD-ROM or another
delivery method may be used.)
2. Open a DOS session on your PC. From Windows®, choose Start, Programs, MS-DOS Prompt.
3. Copy the new image files to a known directory, for example c:\wilan\images. (Create a new
directory if a suitable directory does not already exist.)
This directory is an example only.
C:> copy c:\wilan\images
4. Go to the directory by typing cd c:\wilan\images and press Enter.
5. List the contents of the directory. Type dir and press Enter. The names of image files should be listed in
the directory.

Appendix G: Upgrading Software
6. Type ftp and press Enter where the IP address is the address of the AWE unit. The
PC connects to the AWE unit.
This IP address is an example only.
Enter the IP address of your AWE unit.

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 99.
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 135.
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
36.

Glossary
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.
JUL 2001 Rev 03
157
Glossary
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.
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.
158
AWE 120-24 Installation & Configuration Guide
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.
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
dB = 10 × log ( P1 ⁄ P2 )
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.
JUL 2001 Rev 03
159
Glossary
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.
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.
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.
160
AWE 120-24 Installation & Configuration Guide
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.
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.
IEEE
Institute of Electrical and Electronics Engineers.
image
An image is a collection of configurations or settings for a particular device. 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.

Glossary
link monitor
A 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
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.
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.
162
AWE 120-24 Installation & Configuration Guide
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.
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 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.
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.
JUL 2001 Rev 03
163
Glossary
RS-232
Standards for serial communications, which define the voltages, currents, data rates and
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 unit
measures RSSI as a fade margin value.
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
A unit uses system image files to store system configuration settings. The default system
image file is called “factory-image” and is used when the unit is first powered up.
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 unit can use
telnet to access its configuration menus.
164
AWE 120-24 Installation & Configuration Guide
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.
uptilt
See downtilt.
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-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.
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.
