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.

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:
• 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
for more information.

AWE 120-58 User Guide
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.

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 forward” process where each
packet is handled twice. A dual unit repeater does not slow data throughput.
