AWE 120-58 Installation & Configuration 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 license-exempt 5.7250 – 5.8500 GHz ISM radio band and
has a maximum raw wireless data rate of 12.0 Mbps.
• Provides wireless connectivity at speeds up to eight times faster than regular T1 lines, making the AWE 12058 ideal for providing high-speed Internet access or for wirelessly extending existing communications
infrastructures.
• Supports point-to-point, point-to-multipoint, and multipoint-to-multipoint networks (if all remotes have
clear line of sight to the base station). Contentionless polling ensures efficient access to remote data
networks.
• Is self-contained and easy to use. Simply connect a AWE 120-58 to each LAN segment, and the unit
automatically learns where nodes are located on the network and performs dynamic packet filtering to
ensure the local LAN traffic does not overload the wireless connection.
• Uses Wi-LAN's patented Multi-Code Direct Sequence Spread Spectrum (MC-DSSS) technology, which
makes the unit spectrally efficient and resistant to interference. MC-DSSS technology increases data
throughput by as much as ten times compared to traditional spread spectrum technology.
• Other features include adjustable Tx power level, IP address filtering, throughput throttling and monitoring,
high security and reliability, and a flash-code upgrade path. SNMP, telnet and RS-232 management enable
users to manage, configure and monitor their wireless network with ease.
About Spread Spectrum
Three license-free frequency bands (called the ISM bands) are allocated in Canada and the United States to a
radio technique known as spread spectrum communication. The bands are located at 900MHz, 2.4 GHz, and
5.8 GHz (shown in the following illustration). The AWE 120-58 operates with spread spectrum technology
over the 5.7250 – 5.850 GHz band.

5.725 GHz 5.85 GHz
Direct Sequence Spread Spectrum (DSSS) technology converts a data stream into packets and spreads the
packets across a broad portion of the RF band. The particular spread pattern depends upon a code. With
multi-code DSSS (MC-DSSS), multiple codes and spread patterns are employed. A spread spectrum receiver
reconstructs the signal and interprets the data.
Some advantages of DSSS are as follows:
• Fast throughput: A wide bandwidth means fast data throughput.
• Resistant to interference: DSSS overcomes medium levels of interference and multipath problems.
• Security: There must be a decoder at the receiving end to recover data (an AWE can only talk to
another AWE). Data is transmitted at irregular time intervals. Upon request, Wi-LAN can assign a
customer a data packet security code so that a customer can only receive transmissions from
another AWE with the same code.
• Low probability of detection: Due to a low amplitude signal and wide bandwidth.
• No license fee: A license fee is not required if used in the specified radio bands and the transmitter
power is limited.
About AWE Units
AWE 120-58 units can function as base stations, remote units or repeater bases.
Base Station: At least one unit in your wireless network must be configured as a base station. A base station
acts as the central control unit of the wireless network. The base station polls all remote units and controls
how traffic is routed to and from remotes. The base usually connects to a major access point of the wired
network. The antenna of the base station must be capable of transmitting and receiving radio signals to and
from all the remote units in a system. If remotes are spread over a large area, an omni-directional antenna is
usually required. See Configuring a Base Station , page 16 for information about setting up a base station.

AWE 120-58 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 19 for information about setting up a remote unit.
Repeater Base: A base station can be configured as a repeater base. A repeater is needed when remote
units cannot communicate directly with each other, but direct transfers of data between them are necessary
(as in a true WAN). When configured as a repeater, the base station passes data packets between remote
stations based on the remote group status and a list of MAC (Media Access Control) addresses that the base
station automatically builds. A single repeater uses a method called "store and forward" to receive data from
the originating remote and to pass data to the destination remote. See Setting a Base to Repeater Mode (Base
Station Only) , page 77 for more information. Two units can also be employed as a dual unit repeater (back-to-
back) configuration that maximizes data throughput.
Some System Applications
You can build a wireless network from AWE units and various other components such as cables and antennas.
The following section shows some simple examples of AWE applications.
Making a Simple Wireless Bridge
The simplest example of using a AWE 120-58 is a point-to-point wireless bridge that connects two wired
network segments or LANs. Two AWE units are required: a base station and a remote unit.

Creating a Simple Wireless Network
You can create a point-to-multipoint wireless network by adding several remote units to a base station. A
base station can support up to 1000 remotes, however, Wi-LAN recommends no more than 225 remotes per
base station to esnure high levels of data throughput. See Determine the Number of Remotes, page 111 for
more information.

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.

Obtain Network Plan
The network plan describes the network in detail, including the following:
• Type and number of units
• Physical layout
• Configuration settings for each unit
• Site names, IP addresses and links
• Antenna types, RF cables and cable lengths, surge suppressors, terminators
• Network cable types and lengths
• Grounding kits and backup power requirements
• Link budget
• Floor plans and equipment cabinet requirements.
The network plan must be completed before any equipment is installed. See Appendix A: Planning Your Wireless
Link, page 111 for more information about network plans.
Check your equipment and tools: Ensure that you have all the required parts and equipment specified in
the network plan. You will require a Bench Test Kit (9000-0034) and some tools to install and configure units–
in addition to a standard tool kit, you will require a laptop PC with HyperTerminal® or other terminal
emulation software and RS-232 cable. You may require a spectrum analyzer, Site Master® communication test
set, digital multimeter, 2-way radios, binoculars, strobe lights, ladder, and weatherproof caulking.

Assemble Units
Important
Antennas must be installed by a knowedgeable and professional installer.
WARNING
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.
2. Connect the power supply unit to the Power connector at the back of the unit. The AWE 120-58 must be
connected only to a Wi-LAN approved power supply unit with an output of 12 Vdc. See DC Power Plug
Pinout, page 150 for pinout information.

Checking the Power
To check the power
➧
1. Plug the AC power cord into the AC power outlet.
2. Plug the DC power plug (12 Vdc) to the unit’s power connector.
3. Plug the AC power cord into the power supply unit.
The green Power LED on the front of the unit turns ON and the Air, Mode and Wire LEDs turn ON
briefly then turn OFF.
The green Power LED stays ON. The Mode LED stays OFF (indicating Normal mode). The Air LED is
orange, green, red or OFF. See Front Panel LEDs, page 149 for more information about LEDs.
If the green Power LED does not turn ON, check your AC power source and the power supply unit. Measure
the power supply unit voltage at the DC Power Plug between pins 1 and 2. See DC Power Plug Pinout, page 150.
The output should be 12 Vdc and the power supply unit power LED should be ON.
Pre-Configure Units
This section describes how to pre-configure a base station and a remote unit, which are the basic units
required for a point-to-point wireless link. Once you have configured and tested this basic equipment, you
can configure and test all remaining units. See Configuration, page 33 for detailed information about
configuration settings.
Configuring a Base Station
When you configure a unit as a base station, you need to perform the following tasks.
• Check the Network Configuration information of the unit.
• Set the Station Type of the unit to "Base Station"
• Assign the Station Rank (# equal to or greater than the number of remote units)
• Choose a Center Frequency (must be the same for all units in network)
• Select an Acquistion Code (must be the same for all units in network)
• Set Tx Power Level Adjust intially to "0 dB"
• Set the security passwords (must be the same for all units in network)
• Change the default menu passwords
These tasks are described below in detail.
To configure a unit as a base station
➧
1. Connect a PC to the AWE unit that will be the base station. Connect the COM port of the PC to the
serial port of the AWE with the adapter plug and straight through RS-232 cable.
