AW2400iTR

Operational summary

The AW2400iTR Radio allows the user to create a long-range, wireless Ethernet net-

work with up to 16 subscriber units per access point. The configuration may include

any combination of AW2400xTR, AW2400iTR and AW2400xTP radios.

Configuring a wireless link with the AW2400iTR requires the establishment of six

elements:

• Each radio must know whether it is to be an access point (AP) or subscriber

unit (SU).

• Each radio must have an IP address that is unique among all others on the

same network.

• The AP must know how many SUs are expecting communication with it.

• The AP and any given SU must agree on which radio frequency channel they

are using. This can be manually set or allowed to change automatically.

• The SU must be assigned a unique subscriber ID to specify which time division

slot it will use when communicating with the AP.

• The AP and any given SU must share a common 128-bit encryption key.

AW2400xTR radios are configured by connecting to a computer that will run a web

browser and setting parameters via their built-in browser interfaces. This browser

interface also provides link quality statistics and a graphical spectrum scan to assist

in setup and resolving connection problems.

The access point (AP) automatically scans for the best of the 37 available radio fre-

quency channels, encrypts Ethernet data received from the network, and transmits

it wirelessly to the correct subscriber unit (SU). The AP is constantly monitoring the

radio link and can automatically change the channel if performance is degraded due

to interference. If two AP units are very close to one another, they may interfere

if operating on adjacent frequency channels. Place them at least 10 feet apart or

manually select non-adjacent channels for their operation. Also, the SU should be

placed at least 10 feet from the AP to avoid overloading the radio’s receiver.

Any 10/100 BaseT Ethernet client device (ECD) can be connected to an AW2400iTR

subscriber unit. Each SU encrypts Ethernet traffic received from the attached ECD

and transmits the data wirelessly to its AP. Each SU can be plugged directly into an

ECD without adding drivers or loading software. Essentially, once the AP/SU pair is

configured and running it behaves like a continuous Ethernet cable.
