AWE 120-58 User Guide
Description
Features
The AWE 120-58 advanced wireless Ethernet bridge provides high-speed, wireless connectivity at a fraction
of the cost of wired solutions. It operates over the 5.7250 – 5.8500 GHz ISM radio band and has a maximum
raw wireless data rate of 12 Mbps.
• Provides wireless connectivity at speeds up to eight times faster than regular T1 lines, making the
AWE 120-58 ideal for providing high-speed Ethernet access or for wirelessly extending existing
communications infrastructures.
• Supports point-to-point, point-to-multipoint, and multipoint-to-multipoint networks (if all remotes have
clear line of sight to the base station and to each other). Contentionless polling ensures efficient access to
remote data networks.
• Is self-contained and easy to use. Simply connect an AWE unit to each LAN segment, and the unit
automatically learns where nodes are located on the network and performs dynamic packet filtering to
ensure the local LAN traffic does not overload the wireless connection.
• Uses Wi-LAN's patented Multi-Code Direct Sequence Spread Spectrum (MC-DSSS) technology, which
makes the unit spectrally efficient and resistant to interference. MC-DSSS technology increases data
throughput by as much as ten times compared to traditional spread spectrum technology.
• Other features include automatic Tx power level adjustment, IP address filtering, throughput throttling and
monitoring, high security and reliability, and a flash-code upgrade path. SNMP, telnet and RS-232
management enable users to manage, configure and monitor their wireless network with ease.
• VLAN compliant—supports transparent forwarding of VLAN-tagged frames (increased frame size
supported) and remote management of units within a VLAN environment (i.e. units connected via trunk
links). Supports VLAN tag insertion/removal and VLAN supporting protocols (802.1D, 802.1P, GVRP).
About Spread Spectrum
Three frequency bands (called the ISM bands) are allocated in Canada and the United States to a radio
technique known as spread spectrum communication. The bands are located at 900MHz, 2.4 GHz, and 5.8
GHz (shown in the following illustration). The AWE 120-58 operates with spread spectrum technology over
the 5.7250 – 5.850 GHz band.

Direct Sequence Spread Spectrum (DSSS) technology converts a data stream into packets and spreads the
packets across a broad portion of the RF band. The particular spread pattern depends upon a code. With
multi-code DSSS (MC-DSSS), multiple codes and spread patterns are employed. A spread spectrum receiver
reconstructs the signal and interprets the data.
Some advantages of DSSS are as follows:
•
Resistant to interference: DSSS overcomes medium levels of interference and multipath problems.
•
Security: There must be a decoder at the receiving end to recover data (an AWE can only talk to
another AWE). Data is transmitted at irregular time intervals.
•
Low probability of detection: Due to a low amplitude signal and wide bandwidth.
•
No license fee: A license fee is not required if used in the specified radio bands and the transmitter
power is limited.
About AWE Units
AWE 120-58 units can function as base stations, remote units or repeater bases.
Base Station: One unit in your wireless network must be a base station. A base station acts as the central
control unit of the wireless network.The base station polls all remote units and controls how traffic is routed
to and from remotes.The base usually connects to a major access point of the wired network.The antenna of
the base station must be capable of transmitting and receiving radio signals to and from all the remote units in
a system. If remotes are spread over a large area, an omni-directional antenna is usually required. See
Configuring a Base Station
, page 15 for information about setting up a base station.
AWE 120-58 User Guide
Some System Applications
Remote Units: Remote units receive and transmit wireless data to the base station.You need at least one
remote unit for each wireless link. Remotes can limit the amount of data passed by the remote (a function
called throttling), and they can filter data packets based on their IP address. If remote units communicate only
with the base station, their antennas can be more directional and have higher gains than base antennas. See
Configuring a Remote Unit
, page 18 for information about setting up a remote unit.
Repeater Base: A base station can be configured as a repeater base. A repeater is needed when remote
units cannot communicate directly with each other, but direct transfers of data between them are necessary
(as in a true WAN). When configured as a repeater, the base station passes data packets between remote
stations based on the remote group status and a list of MAC (Media Access Control) addresses that the base
station automatically builds. A single repeater uses a method called “store and forward” to receive data from
the originating remote and to pass data to the destination remote. See Setting a Base to Repeater Mode
(Base Station Only)
, page 102 for more information. Two units can also be employed as a dual unit repeater
(back-to-back) configuration that maximizes data throughput.
Some System Applications
You can build a wireless network from AWE units and various other components such as cables and antennas.
The following section shows some simple examples of AWE applications.
Making a Simple Wireless Bridge
The simplest example of using a AWE 120-58 is a point-to-point wireless bridge that connects two wired
network segments or LANs. Two AWE units are required: a base station and a remote unit.

Creating a Simple Wireless Network
You can create a point-to-multipoint wireless network by adding several remote units to a base station. A
base station can support up to 1000 remotes, however,Wi-LAN recommends no more than 225 remotes per
base station to ensure high levels of data throughput. See Determine the Number of Remotes
, page 135
for more information.

Some System Applications
Creating a Network with Cells
Cells or data nodes can be created with AWE units to maximize coverage, minimize interference, and
increase data throughput. Directional antennas are mounted on a mast to divide cells into sectors.Each sector
is connected to an antenna and a base station. Directional antennas increase signal gain within the sector and
increase the distance possible between base stations and remotes. Center frequency, acquisition code and
antenna polarization techniques are used to isolate sectors. The increase in data rate depends on the number
of sectors. For example, the data rate of Cell 1 in the diagram below is 36 Mbps (12 Mbps x 3 sectors). Cells
are distributed across a service area and can be linked to each other via a wireless link or a fiber optic cable.
Implementing a network with cells requires comprehensive network planning and site preparation. Please
contact Wi-LAN for information about creating a network with cells.

Using a Repeater Base
A base station can function as a repeater to enable wireless data communication around physical obstacles
such as tall buildings or mountains. The repeater passes data around the obstacle to any remote in the same
RF group. The single unit repeater slows data throughput due to the “store and forward” process where each
packet is handled twice. A dual unit repeater does not slow data throughput.

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

Installation
5 Install Units
This section provides some guidelines about installing units in the field.
WARNING
All antennas must be professionally installed following accepted safety,
grounding, electrical, and civil engineering standards.
! CAUTION
Never operate a unit without an antenna, dummy load, or terminator
connected to the antenna port.
Operating a unit without an antenna, dummy load, or terminator connected
to the antenna port can permanently damage a unit.
•
Install the units at locations identified in the network plan.
•
Verify that there is no interference at the site by performing spectrum sweeps with a spectrum
analyzer. Perform sweeps at various times of the day (for example, 9AM, noon, and 3 PM are peak
telephone traffic times.) If there are problems, contact the network planner, who may need to change
the system configuration or design.
•
If test equipment is available, sweep antennas and cables with the Site Master ® communications test
set before securing antennas and cables to towers, while they are on the ground and easy to access.
Sweeping helps to ensure that antennas and cables will operate as expected.
•
Initially install equipment with flexibility—do not tie down cables, antennas should be free to move,
allow some slack in cables, avoid drilling and do not seal connections.
•
Align antennas*. (Two people are required, one at the base station and one at the remote unit. When
in the field, you may require binoculars and 2-way radios to communicate.) When aligning antennas,
adjust the orientation of the remote antenna while running a link monitor test between the remote
and the base station. Adjust the antenna until you achieve the highest fade margin with no bit errors
(BER = 0). See Performing Link Monitor Test (Normal Mode)
, page 72 for instructions. Repeat
the antenna alignment procedure for each remote.
•
When antennas are aligned and cables are secured, sweep the antennas with the Site Master test set
a final time before connecting to AWE.
•
Perform diagnostic tests on the installed system. Compare field results to bench test results using
ping, ftp, fade margins, etc. Document your results (these results will be very useful when
troubleshooting and monitoring the system’s performance).
•
When the system works as specified, lock down and weatherproof all equipment and connections.
* The antenna(s) used for this transmitter must be fixed-mounted on outdoor permanent structures with a separation distance
of at least 2 metres from all persons and must not be co-located or operating in conjunction with any other antenna or
transmitter.

Point-to-Multipoint Installation
The procedure for installing a point-to-multipoint system is the same as the procedure for installing a pointto-point system. Treat each link in a point-to-multipoint system as a single, point-to-point wireless link.
Co-Location Installation
When you install a system with sectors and co-located base stations (see Creating a Network with Cells
page 5 for an example), you install and test sectors as if they were point-to-point systems; however, in this
case you must ensure that individual sectors are not interfering with each other. Please contact Wi-LAN for
information about planning and installing co-located units.
•
Align and test the first sector. Measure the fade margin and run the link monitor test. Document your
results, then turn off the radio in the first sector.
•
Align and test the second sector. Measure the fade margin and run the link monitor test. Leave the
link monitor test running in the second sector.
•
Turn on the radio in the first sector again and run the continuous transmit test. See Performing
Transmit and Receive Tests
, page 75.
•
Observe the BER and fade margin of the second sector radio. Look for changes to determine if the
first sector is interfering with the second sector.
•
Repeat the tests for all sector/pair combinations.
6 Test Network
Run the link monitor test and other tests such as ping and ftp file transfers to verify network operation when
the units are installed in the field. See Performing Link Monitor Test (Normal Mode)
, page 72.
Adding to a Network
Always add to your network one link or device at a time, working from a known base network. Measure and
document changes to the system and changes in performance. For example, you can transfer files with ftp
and measure the performance with LAN analyzer software. The key to a successful network is to proceed
one step at a time and to understand your network!

Preventative Maintenance
and Monitoring
You should set up a preventative maintenance schedule for your network. Wi-LAN recommends that the
following preventative maintenance be performed at least semi-annually.
•
Regularly run link monitor tests across the network and measure BER and fade margin.You can also
test the network with ping, ftp and file transfers. Other resources are available on the Internet that
can help you monitor the performance of your link.
•
If you have SNMP application software, you can check unit operation from a remote location. See
Appendix D: SNMP , page 157 for more information.
If you have SNMP application software, you can check unit operation remotely. See Appendix D: SNMP
page 157 for more information.
You should periodically perform a physical inspection of each site.
• Check that antennas and cables are secure and have not become loose.
• Check for physical obstructions in the line-of-sight radio path, such as trees and buildings.
• Sweep antennas and cables to ensure that antennas and cables are intact and operating properly.
• Check that there are no water leaks in cabinets.
• Check weatherproofing.
• Check for new sources of electromagnetic interference.

Filtering
Two different IP filters are available: a packet filter, and an address filter. The IP packet filter determines which
type of packets are allowed to pass through a unit. If the IP Packet Filter is OFF, the unit passes all packets. If
the IP Packet Filter is ON, the unit passes only IP and ARP (Address Resolution Protocol) packets.
IP address filters are actually tables that contain lists of IP addresses. Data packets are either passed or
blocked depending on whether the packet IP address is listed in the table, the setting of “Default IP Address
Filtering” (pass or block), and the “State” setting of each filter.

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

MAC Address Filter Configuration
The MAC Address Filter Configuration menu enables you to create, modify or delete entries in the MAC
Address Filter Table.
By creating a MAC address filter, you control whether this MAC address gains access to the network. The
filter you specify contains a control element for each port which defines the access level of the MAC address
for that port.
One example filter may be to block the relay of particular bridge protocol packets that use a known multicast
address. By specifying “Filter” access for each port, you can restrict these packets to the local LAN(s) from
which they originate.

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

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 78 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 100 means
that 100 x 64 kbps will be passed.When throttling is disabled, the unit uses the maximum available bandwidth.
The default setting is to disable throttling.

RF Station Configuration
Setting Tx Power Automatically (Remote Station Only)
Output Power Control Mode can be used to adjust a remote unit’s Tx power automatically. Three different
modes are available: off mode is selected to run Link Monitor in the usual manner (where Link Monitor tests
the link and collects statistical information). Automatic Output Power
mode tests the link (with Link
Monitor) and automatically adjusts Tx power up or down based on measurements taken when the mode is
selected. Dynamic Output Power
mode runs Link Monitor in the background and periodically adjusts Tx
power in response to the current radio conditions and environment. The amount of bandwidth (test
overhead) used for all modes is set with Link Monitor Period
. (See Setting the Link Monitor Period
page 78).
How Automatic Output Power Adjustment Works
Link Monitor tests a link by sending test packets and measuring the link’s performance (in terms of BER and
power). The results of the test can be used to automatically adjust Tx power. Automatic power level
adjustment is explained below.
The maximum Tx power output (factory-set power ceiling
) of a unit is set at factory and cannot be
changed with configuration menus (for more information see Viewing Unit Identification
, page 35). A
user-specified power ceiling
or limit can be set by the user using User Output Power Adjust Ceiling on
the RF Station Configuration screen.The user-specified ceiling is the maximum Tx power level with which the
user allows the unit to operate.
Factory-set Power Ceiling
User-specified Power Ceiling

Automatic power adjustment

Operating Tx Power Level
(Base Tx Power Level + Signal Margin)
Signal Power
Signal Margin
Base Tx PowerLevel
Noise Floor
The noise floor is the power level below which signal quality deteriorates rapidly due to random radio
interference causing the link to not function properly. Base Tx Power level is the starting power level or
"base" from which the adjustment is made. The operating Tx Power level
is the sum of the base power
level and the signal margin (fade margin)—the signal margin is added to the Tx base power level and moves
with it. Both the base power level and the signal margin can be adjusted to reach the operating power level,
When a unit adjusts the power level, it begins at the base power level and runs Link Monitor. If no bit errors
occur and the power level is satisfactory, the unit automatically drops the Tx power level by one dB and runs
Link Monitor again. If no bit errors occur again and power level is adequate, it once again drops the Tx power
APR 2002 Rev 03
83
Configuration
level by one dB and runs Link Monitor. This process repeats until a power level occurs where no bit errors
occur and power level is lowest. This level is the minimum power level required for operation and is displayed
numerically by Current Output Power Level Adjust on the screen. When the unit reaches this
level, Tx Power (seen on the Radio Module Configuration screen) is automatically reset to the new level.
(Below this level, BER and power levels are unsatisfactory for data communication) . If the intitial base Tx
power level is below the noise floor, a unit will automatically increment the power level by one dB until the
BER and power level become satisfactory.
In short, two modes of automatic power level adjustment are available: automatic and dynamic.
Automatic Output Power mode: Power is monitored and automatically adjusted once when the
automatic output power mode is activated. The resulting output power value is saved and Output Power
Control Mode automatically returns to “off”.
Dynamic Output Power mode: Power is monitored and automatically adjusted periodically during
regular operation. Some bandwidth for data is lost due to test packet overhead—the amount of overhead is
determined by setting the Link Monitor Period (see Setting the Link Monitor Period
, page 78). Dynamic
Output Power mode is not recommended in co-location situations.
Note: A unit will adjust the power output to compensate for noise problems, however if the noise floor is
too high the unit will not be able to establish an RF link. In this case, an RF spectrum analysis should be
performed to determine the cause of the problem.
Tx Power Adjust on the Radio Module Configuration screen is used to set the initial or base Tx power
level. After the level is set automatically, this value is automatically reset by the unit. The reset value can
be read by viewing Current Output Power Level Adjust on the RF Station Configuration screen, or by
viewing Tx Power Level Adjust on the Radio Module Configuration screen.

RF Station Configuration
Setting Signal Margin (Remote Station Only)
The signal margin is the extra transmit power (measured in dB) desired for a remote unit with respect to the
base station noise floor. 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 89.
2. Select Config Test Minutes. To begin, enter a time of 15–20 minutes. See Setting Config Test
Minutes , page 92.
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 109.
5. If the unit operates as expected, you can save the current settings to “Flash”. See Rebooting and
Saving RF Module Configurations
, page 109.
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 109.

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 105.

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.
Center Frequency Spectrum
66 MHz
16 MHz
33 MHz
16 MHz
Data
Region
Side
Lobe
Side
Lobe
5.7410 GHz
5.8338 GHz
Center Frequency
Only the 33 MHz data region of the 66 MHz spectrum contains data; the remaining 16 MHz side lobes
contain no useful information (frequency ranges given are approximate).The side lobes operate at a much
lower power than the data region.
If only one center frequency is required, simply choose a frequency between 5.7410 GHz and 5.8338 GHz (in
400 kHz increments).You will probably choose a center frequency where the 5.8 GHz ISM band is cleanest,
meaning a frequency where no other people are transmitting.
If two or more AWE 120-58 systems must be co-located, center frequencies are selected that have as much
separation as possible so different systems do not interfere with each other. It is very important that the 33
MHz data regions of adjacent systems do not overlap. System performance is also better if the side lobes of
one system do not overlap the data region of another system. It does not matter if the side-lobes of two
systems overlap.
APR 2002 Rev 03
95
Configuration
Some examples of center frequency separation and performance ratings are provided below.
Excellent
Good
Fair
Poor
These examples show that there is no benefit to separating the center frequencies of adjacent systems by
more than 66 MHz. 48 MHz of center frequency separation is more than adequate in most cases. Separation
of 33MHz is adequate for strong RF links, but weak signals will be degraded by the overlap of the side-lobes
into the data region. Overlapping of data regions is not recommended and will cause problems.
The following diagram shows seven different center frequencies in the 5.8 GHz ISM band that are spaced as
far apart as possible.You can choose your center frequencies from these sample schemes.
Sample Center Frequency Schemes for Co-located Systems
1 System Choose any one center frequency
2 Systems Choose two center frequencies
3 Systems
4 Systems
5.8500
5.8338

5.7803
5.7874
5.7718
5.7562
5.7410
5.7250
Center Frequency (GHz)
For best performance, choose center frequencies that are separated as much as possible and nonoverlapping. Three co-located system could use the A,D and G center frequencies. Frequencies B, D and F
would probably work equally as well. Four co-located systems could use the A, C, E and G frequencies.
Having more than four co-located systems would require careful radio network planning to ensure the
proper operation of each system.

Passwords are always exchanged between units when they communicate with each other. A set of five
security passwords is assigned to each unit. Each password may be up to 8 digits long in hexadecimal.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

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 Tx power you set is the initial value only if you decide
to set Tx power automatically–the power level resets automatically during the test. See Setting Tx Power
Automatically (Remote Station Only)

Setting a Base to Repeater Mode (Base Station Only)
When repeater mode is enabled at a base station (Repeater Mode = on), the base acts as a repeater in
addition to performing its normal base station functions. As a repeater, the base station receives incoming
messages from remotes, stores them and broadcasts them to all remotes within RF range. Remotes belonging
to the same RF group (with the same RF Group number) can communicate via the repeater. (See Setting
Remote Unit RF Group
, page 106 for information about RF groups.) The diagram below explains the
process.

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 allots 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 allots the base one time slot per polling cycle .
A symmetric system gives the base station the same polling priority as a remote unit.

Radio Module 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.The remote either does not respond to the poll, or it responds with
a negative acknowledgement. The base then considers the remote to be idle. (This process is called dynamic
time allocation or DTA.) Idle remote units are ignored by the base station for the number of polling rounds
entered in the Dynamic Polling Level field. The higher the dynamic polling level, the more efficient the
throughput and the longer it takes to move a subscriber from an inactive state to an active state. Dynamic
Polling improves system performance whenever there is more than one remote. When there are a large
number of remotes system performance improves significantly.
Note: Polling level is set only at the base station.

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

RF Group = n
n = 1 – 63
RF Group = 14
Human Resources

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.

AWE 120-58 User Guide
Radio Module Configuration
A repeater is used to bypass obstacles that block the RF path (for example, a mountain). When a base station
is set to repeater mode (Repeater Mode = on), it can pass data from remotes in an RF group to other
remotes in the same group. A system with a repeater is a closed system. Example 3 shows a repeater with
four remotes. All the remotes are in the same RF Group 4, so they can talk to each other via the repeater
base.
Example 3: Repeater Configuration (Closed System)

Closed remote units (RF Group = 0) can be combined with open remote units (RF Group = non-zero) within
the same system. In this case each group in the system behaves according to its RF Group characteristics:
closed remotes could communicate only with the base, remotes with the same (non-zero) group number
could communicate with each other, and remotes with different (non-zero) group numbers could not
communicate with each other. A base or repeater would not pass packets originating from a closed remote.
The following table summarizes the first three situations.
Repeater Mode

RF Group

System

Repeater Mode =

Remotes can communicate directly with

(if a LOS RF path can be established)
Repeater Mode =

Remotes can communicate only with the
base station—they cannot talk to each
other
Repeater Mode =
on
1–63
Open
Remotes cannot communicate directly with
each other, they can only communicate via
the repeater base with other remotes that
have the same RF group number
In a mixed system, each RF group behaves according to the RF Group characteristics assigned to it (0 =
closed, 1–63 = open; same non-zero group number = communication, different non-zero group number = no
communication).

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.

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 28 for information.
•
After periods of extreme weather, perform link monitor tests to verify the system; inspect towers,
antennas, cables and connectors for damage.
•
Change menu passwords so that only key personnel can reconfigure the system. See Setting Menu
Passwords , page 117.
•
Keep records of recent changes. Especially document the addition of units, hardware and software
changes and changes to configuration settings. Configuration errors often cause other problems.
Current records can be compared with original installation records and function as a benchmark to
help you troubleshoot.
•
Keep a log of past and present problems and solutions. Store the log on-site, if possible. The log
identifies common failure points and fixes.
•
Before contacting Wi-LAN for customer support, document the symptoms of the problem and the
steps taken to diagnose and fix the problem. Record the current configuration of the system.

Troubleshooting
Troubleshooting Areas
There are five key areas to be aware of when troubleshooting.
Network Integrity: Continued performance and reliability of a network depends upon maintaining the
integrity of the network. If you change a network’s design, you will affect its operation. Be aware of recent
changes to your network.
Quality of RF link: Data communication depends first on the quality of the RF link. If you can establish and
maintain a high-quality RF link, then you can be sure the link will carry high-speed data. If the quality of the RF
link is degraded for some reason, the quality of the transmitted data will also degrade.
Radio Hardware:There are three basic parts to a AWE: radio unit, antenna feed (cable, connectors, surge
suppressors, patch cables etc.) and antenna.You can isolate faulty hardware using measurement and/or
replacement methods.
•
Verify the radio unit with diagnostic tests (such as RSSI and link monitor tests), bench test a unit, or
replace a unit.
•
Verify the antenna feed with a Site Master test set. Sweep cables, connectors and lightning suppressors,
or exchange these parts for known good parts.
•
To verify the antenna you can sweep the antenna with the Site Master test set or exchange the antenna.
Correct Unit Configuration: Units must be configured correctly, according to the network plan.
Configuration errors can cause an inability to communicate or poor performance. The addition of units or
changes to your system may require you to change configuration settings.
Embedded Software: Operate with a proven software image. Download new software if you suspect that
a unit’s software is corrupted.
The following chart provides answers to some of the more common problems that can occur when installing
and using a AWE bridge.

AWE 120-58 User 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
unit. Plan some alternate links in case base station coverage areas overlap or if physical obstacles block the
radio path to some remotes.
APR 2002 Rev 03
135
Appendix A: Planning Your Wireless Link
Measure the Distance Between Units
Use a mapping method or GPS (global positioning system) to measure the distance between the base station
and each remote, and check the radio path to identify any obstructions in the LOS path between the two
antennas. Due to the high frequency and low output power permitted in the ISM bands, no obstructions can
exist between the base station and the remote unit.
Determine Shelter, Power and Environmental Requirements
AWE units must be located in a weatherproof environment (a room, EMS cabinet or shelter) with an ambient
temperature between 0º and 40º Celsius, and humidity from 0 to 95% non-condensing. Consider building,
electrical power, heating and air conditioning requirements.
Determining Antenna
and Cable Requirements
The signal from an indoor antenna can penetrate several walls, although metal obstructions or building
features such as elevator shafts can deflect or inhibit radio waves. On-site testing is advised because all
interiors are unique.
If you plan to install antennas outdoors you need to consider several factors.
•
Ensure a clear line-of-sight radio path is available between each remote and its base station.
•
Ensure that Fresnel zone clearances are met. Identify obstructions that could degrade link
performance now and in the future.
•
Obtain permission from building owners if you intend to install the antenna on a rooftop
•
Obtain 24-hour access to antennas, cables and equipment
•
Determine antenna mounting positions: the final position should be selected to enable physical
shielding of the antenna at the back and sides from radio interference in the ISM band.
•
Consider potential wind load and ice loading impact on the antenna
•
Be aware of possible multipath effects: installing an antenna too close to reflective surfaces can cause
signal problems.
•
Check local regulatory restrictions, such as height, on antenna mast usage in the identified location
•
Ensure that your antenna is properly grounded and installed according to local electrical codes.
•
Determine transmission cable lengths and plan cable routes. Minimize the length of the coaxial cable

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 120-58 is calculated as follows.
Note: For the sake of simplicity, a Tx Power value of 20dBm is used in the following calculations.
Formula:
System Gain = Transmission Power - Receiver Sensitivity @ 10-6 BER
Variables:
Tx Power = 21 dBm
Receiver Sensitivity = –80 dBm (receiver sensitivity @ 10-6 BER)
Calculation:
21dBm – (–80) dBm = 101 dB
To ensure reliable communications, the system gain plus all antenna gains must be greater than the sum of all
losses. For a reliable link,Wi-LAN recommends that the system gain plus all antenna gains be greater than the
sum of all losses by 15 dB. This amount is the fade margin.
EIRP (Effective Isotropically Radiated Power)
EIRP is the power that radiates from an antenna, taking into account the output power from the transmitter,
the connector and cable losses, and the antenna gain. Unlike the Tx output power of the devices, EIRP takes
account of antenna gain and cable losses. Antennas use directional gain to increase the effective radiated
power. Losses such as cable losses reduce the effective radiated power.
You calculate the EIRP as follows.
Formula:
EIRP = Tx Power (dBm) - Cable Losses (dB) - Connector Losses (dB) + Antenna Gain (dBi)
Note:
The FCC regulatory body has set the EIRP limit to +36 dBm for point-to-multipoint
applications per FCC 15.247(b)(3). For point-to-point applications EIRP can be >36 dBm
as per FCC 15.247(b)(3)(ii).
Visit www.fcc.gov for the most current information.
Industry Canada specifies the EIRP limit to ≤ 4W (+36 dBm) as per RSS-210, 6.2.2(o)(b)
for point-to-multipoint applications and 200W (+23 dBW) for point-to-point applications.

AWE 120-58 User Guide
Calculating a Link Budget
Antenna Gain
To ensure the best range and interference suppression, the external antenna should be directional, focusing
the radio energy in one direction (toward the other end of the link) rather than onmi-directional. Use of a
directional antenna also reduces interference from other systems operating at the same frequency.
Note: In some situations, you may want to use an omni-directional antenna in your system design. For
example, you would use an omni-directional antenna for a base station with remote sites situated in a
360º path around it.
When you select a Wi-LAN approved antenna, pay particular attention to the gain specification. When you
select an antenna for a remote station, select an antenna with a gain that provides at least 15 dB fade margin.
Antenna gain is specified in either dBi or dBd. When an antenna is specified in dBd, add 2.14 dB to the value
to convert it to dBi.
Propagation Loss
Propagation loss is the attenuation (reduction) in RF signal energy as it travels through space. In most wireless
systems, losses through space are the major contributor to signal attenuation. When you know the intended
installation locations of the base and remote stations, determine the physical line of sight distance and then
calculate the RF attenuation as follows:
Formula:
Attenuation (dB) for 5.8 GHz band = 108 dB + 20log(dkm)
where:
dkm = Distance in Kilometers
108 dB = Pathloss Constant in the 5.8 GHz band
Fresnel Zone
It is essential that you locate your antennas at maximum above-ground height to ensure that all ground-based
obstructions are cleared from the Line of Sight path and the Fresnel Zone.
The Fresnel Zone is the expansion of the RF signal radio angles in the vertical plane near the middle of the RF
path.

Appendix A: Planning Your Wireless Link
For the 5.8 GHz band, the approximate Fresnel Radius is calculated as follows.
Formula:
Fresnel Radius (meters)=
2.2 d km + ( d km ⁄ 8.12 )
Cable Loss
Cable and connector losses affect the operation of the wireless link and therefore should be kept to a
minimum by minimizing cable lengths and carefully selecting the type of cable. The two primary coaxial cable
specifications for the AWE 120-58 are:
•
Cable must be 50 ohms nominal impedance
•
Cable must be of a low loss type
The following is an example of cable loss ratings at 5.8 GHz.
Cable Type
LDF2-50
LDF4-50A
LDF4.5-50
Loss (dB/meter)
0.32
0.22
0.16
Note: When you calculate path loss, you will add 1dB at each end of the link to compensate for connector
losses in addition to the cable loss value.
Path Loss
Path loss describes the total RF attenuation throughout the system from Tx antenna to Rx antenna. This
includes the losses as the RF signal travels through space plus Tx and Rx cable loss, and Tx and Rx connector
loss. Use the following formula to calculate path loss.
Formula:
Path Loss = Tx and Rx Cable Loss + Tx and Rx Connector Loss + Propagation Loss
Once you know the path loss, you can compare the value to the system gain value. If the system gain value is
greater than the path loss, the link is feasible. See System Gain , page 138 for more information about system
gain.
Fade Margin
Fade margin is the amount by which the system gain plus the total antenna gain exceeds the path loss.
Formula:
Total antenna gain = Tx Antenna Gain + Rx Antenna Gain
As calculated, the fade margin is the number of dB that the received signal strength exceeds the minimum
receiver sensitivity.You require some level of fade margin for any wireless system to compensate for RF path
fading due to weather conditions or multipath interference.
The Wi-LAN recommended fade margin for the AWE 120-58 is a minimum of 15 dB. The sum of the cable
losses, connector losses, propagation losses, and the 15 dB required fade margin should be less than the sum
of the system gain and antenna gain.

Formulas:
or
Actual Fade Margin ≥ System Gain + Antenna Gain – Propagation Loss

Variables:
Desired Fade Margin = 15 dB
Tx Power = 21 dBm
Rx Sensitivity = –80 dBm
Tx Antenna Gain = 27 dBi
Rx Antenna Gain = 27 dBi
Propagation Loss for desired range of 10km = 108 + 20 x log(10) = 128 dB
Tx Cable Losses (5m LDF2-50) = 5 * 0.32 = 1.6 dB
Rx Cable Losses (5m LDF2-50)= 5 * 0.32 = 1.6 dB
Tx Connector Losses = 1 dB
Rx Connector Losses = 1 dB
Variable
Calculations:
System Gain = 21 - (–80) = 101 dB
Antenna Gains = 27 + 27 = 54 dBi
Cable Losses = 1.6 + 1.6 = 3.2 dB
Connector Losses = 1 + 1 = 2 dB
Actual Fade
Margin
Calculation:
Actual Fade Margin = 101 + 54 – 128 – 3.2 – 2 = 21.8 dB
Analysis:
A goal of Actual Fade Margin ≥ 15 dB is achieved.
The values for cable and connector losses in this example are only for illustration.You will need to work these
out for your specific installations.

Antenna Basics
Antennas focus and absorb radio energy in specific directions, depending on their design. AWE 120-58
antennas must be tuned to 5.7250 – 5.8500 GHz.
This section contains basic information about antenna parameters and how to select and install antennas for
use in your wireless system. Antenna characteristics, mounting location, and correct operation of antennas
are critical to a wireless link.
Antenna Parameters
Parameter
Description
Gain
• Antennas have a gain associated with them, which is a measure of their ability to
amplify signals in their tuned band
• Antenna gain is achieved by focusing the signal. A higher gain antenna has a more
compressed signal
dBd vs. dBi
• Antenna gain must be measured over a known reference and is often expressed as
either dBd or dBi
• dBd is antenna gain referenced over a half-wave dipole which is an antenna that has a
donut shaped radiation pattern
• dBi is antenna gain referenced over an isotropic radiator which is a theoretical
antenna that radiates equally in all directions (e.g. the sun)
• Wi-LAN references antenna gain in dBi. The conversion factor is 0 dBd = 2.14 dBi
Beamwidth
• Describes how a signal spreads out from the antenna, and the range of the reception
area
• Beamwidth is measured between the points on the beam pattern at which the
power density is half of the maximum power. This is often referred to as the –3 dB
points
• A high gain antenna has a very narrow beamwidth and may be more difficult to align
Downtilt or
uptilt
• Some antennas have either an associated downtilt or an uptilt. The tilt further
focuses the signal downward or upward with respect to the horizon
• Tilt may be either electrically built into the antenna or achieved mechanically with
the mounting gear
• Downtilt or uptilt may be required when there is a significant deviation between the
elevation of the remote site(s) and the base site
F/B
• Front-to-back ratio
• Directional antennas focus the signal in a forward path. Achieved by directing the
signal in one direction that reduces the signal in the opposite direction
• A higher gain antenna typically has a greater F/B ratio
142
AWE 120-58 User Guide
Antenna Basics
Parameter
Description
XPD
• Polarity and Cross-Polarization Discrimination (XPD)
• Antennas have an associated polarity, which is the orientation of the radiating
element with respect to earth
• Antennas are usually described as vertical, horizontal, or circularly polarized. The
polarity of all antennas used in a system must be the same
• Cross-Polarization Discrimination specifies the signal isolation achieved when the
receiving element is perpendicular to the radiating element. Can be advantageous
when co-locating radio systems
VSWR
• Voltage standing wave ratio
• VSWR is the voltage ratio of minimum to maximum across a transmission line
• A VSWR of 2.0:1 or less in an antenna is considered effective. Most antennas have a
VSWR of 1.5:1
• For example, when using a radio with a 4 W output with an antenna VSWR of 1.5:1,
the reflected power will be 160 mW
Implementation Considerations
Some key items to consider when selecting and installing antennas for your wireless network follow.
Item
Description
Absorption
• Antennas mounted too close to “soft” objects, such as trees, may experience a
reduction in signal strength due to absorption
• Absorption is most often encountered in applications installed during the fall or
winter months, and the problem does not become evident until the spring
Diffraction
• Diffraction occurs when a radio signal reflects or bounces off of a solid object
• Level of diffraction could lead to connectivity problems if the remaining signal level is
too low
• Two types of diffraction are shadowing and multipath
Shadowing
• Shadowing is a form of diffraction that is typically caused when antennas are mounted
too close to a structure and they lose a portion of the signal lobe due to reflection.
The receive antenna is in a shadowed area
• To minimize shadowing, ensure that there is adequate height above structures when
mounting antenna equipment
Multipath
Interference
• Multipath is a form of diffraction in which the reflected signal arrives at the receiver
at different times which confuses the receiver
• Multipath may be interpreted as interference by the receive antenna and can result in
bit errors and processing delays

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.
144
•
What is the operating frequency range?
•
Will this be a point-to-point or point-to-multipoint application? Ensure that you consider if the
application will change in the future.
•
What are the coverage requirements?
•
What is the gain requirement?
•
What is the elevation of the remote site(s) with respect to the base station and will additional
downtilt/uptilt be necessary at either the base or remote site to compensate?
•
Will there be any obstructions in the path?
•
Will systems be co-located? What polarity will be used?
•
What are the regional environmental conditions? For example, is there windloading, salt air, excessive
moisture, ice buildup etc.?
•
What is the antenna lifetime expectation?
•
What are the site and mounting options?
•
What are the restrictions in the locale regarding the effective radiated power permitted from the
antenna?
•
Will antenna appearance be a factor?

Installing Antennas
Antennas must be installed professionally to ensure that the antenna operates properly and follows accepted
safety, electrical, grounding and civil engineering standards.
Ensure the following conditions.
146
•
Dipole antennas are oriented vertically (point up).
•
Antennas for the system have the same polarity (vertical, horizontal or circular).
•
Connectors attaching the coaxial cable to the antenna are properly weatherproofed.
•
A drip loop is formed at the building entrance to prevent water flowing down the coaxial cable and
entering the installation building.
•
The coaxial cable is secured to the supporting structure at one meter intervals to prevent wind
damage and frost loading problems.
•
The antenna is firmly attached to the mast to prevent it from falling, yet has some flexibility so you
can move the antenna to fine-tune its position.
•
The coaxial cable is connected to the antenna and to the Antenna port on both sides of the link (base
and remote stations).
•
The antennas are grounded properly.
AWE 120-58 User Guide
Antenna Basics
Fine-tuning Antennas
You can fine-tune the antennas by physically moving the antenna. When the remote antenna is correctly
aligned, the Air LED is orange, indicating communication with the base station.You can use the Receive and
Transmit Tests to test the link while adjusting the antennas to minimize BER and lost packets and maximize
received power.You can use the RSSI Test to maximize RSSI.
Once antennas are adjusted to maximize performance, secure them properly to the support structures.
Co-locating Units
When AWE antennas are located on the same mast, you must take care to ensure the output power from
one radio does not overpower another co-located bridge, even if the units are operating on different
channels.You may need to install a signal attenuator to lower transmit power, use antenna polarity to your
advantage, or adjust antenna uptilt or downtilt. Contact your distributor for antenna and installation
assistance when co-locating units.

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.

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 120-58 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.

Appendix E: Configuration Via the Web
Overview
The AWE 120-58 is remotely configurable via the Web using a standard Web browser. All configuration
parameters described in previous sections are configurable through this graphical interface.
This section explains the process of accessing the web pages provided and comments on the layout of these
pages, noting the differences between the Web interface and the menu interface.
Accessing the Web Pages
➧ To start a configuration session via the Web
1. On your PC, open a web browser application and specify the IP address of the unit you wish to access in
the URL field. For example, if the IP address of the unit is 192.168.1.100, the URL specified is: http://
192.168.1.100. Press Enter to load the page.
2. A login prompt should now appear, requesting for a user name and password. Leave the user name blank.
For the password field, enter the same password used to access the menu interface. Click on Enter to
submit your password.
3. If the password is accepted, the main web interface screen should appear. Follow the instructions
provided to continue your configuration session.
Web Interface
APR 2002 Rev 03
171
Appendix E: Configuration Via the Web
Configuration Interface
The layout of Web pages provided mirrors the layout of the menu interface; parameters grouped together in
submenus described in previous sections are similarly grouped together in web “subpages”. Links to these
pages are provided after user authentication is complete via a menu bar.
Unit configuration is achieved by filling out forms provided by each configurable subpage. These pages are
accessed by clicking on appropriate links in the menu bar. Pressing a form submit button will send your entry
data to the unit for processing. Specified parameters are then updated (pending valid input and access
permission), and any requested tasks are run.
172
AWE 120-58 User Guide
Overview
Differences Between the Menu Interface
The one appreciable difference between the menu interface and the Web interface is the statistics submenu.
For the Web interface, Link Monitor Statistics and RF/Ethernet Statistics, two distinct menus in the menu
interface, are combined into one subpage. The link for this page is Monitor Statistics, located in the menu
bar.
Within this subpage, a link to Real-Time Statistics is provided. Accessing this link will load a JAVA ™
applet. This applet will query the unit periodically and report back to you via a live-update graphical statistics
display.
Note: Depending on the version of your browser,the Real-Time Statistics link may prompt you to install a
JAVA™ Plug-in. If you receive this prompt and wish to load the Plug-in, your computer must have access to
the Internet.

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

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

Password:
8. Type the supervisor password for the unit and press Enter. (Supervisor access is required to change unit
settings–see Setting Menu Passwords
, page 117). The ftp> prompt appears.
9. After the ftp prompt, type the following “put” command.
ftp> put .\
Note: Leave a single space after “put.”

Tip: If you type ftp> help, online instructions for using ftp are displayed.
11. Type bye and press Enter to exit ftp and return to the DOS window.
12. Activate the new software image. See Activating New Software Images, below.
Activating New Software Images
After you download new image files to a unit, you need to configure the unit to operate from the new image
rather than from the current image. If you are on-site, you can use the Main Menu to select the default image.
See Setting Default System Image
, page 122.
If you are at a remote location from the unit, you can use telnet to access the unit’s configuration menu or
use SNMP manager software (SNMP parameter = defaultImage) to choose the default image file. See
Appendix D: SNMP , page 157.
Removing Old Software Images
To delete old software images from a AWE unit, you must use ftp to connect to the unit, log in as a
“supervisor” and delete images using the “ftp delete” command. Images The amount of flash memory
available to store images is limited. To see the amount of memory available, see Viewing System Revision
Information , page 37.
