Networking Alpha Signs (9700-0112C) October 8, 2003

Wireless network—transceiver

A wireless network is an effective choice when:

• the cost of a wired connection is too expensive,

• the sign is at a greater distance than is recommended,

• you cannot physically run wiring to the sign’s location, or

• the signs may frequently change location.

Wireless networks allow you to transfer data between PCs and signs that are not physically connected. A PC

communicates with one or more signs through a transceiver (trans

mitter/receiver). One transceiver at the PC (the

master transceiver) transmits messages to a second transceiver (the remote transceiver) in or attached to a sign

located elsewhere.

There are two types of wireless networks:

• LAWN (Local Area Wireless Network)

• WAWN (Wide Area Wireless Network)

Adaptive Micro Systems does not provide wireless messaging hardware or technical communication services

for most Alpha indoor signs. If you are interested in this type of network, we recommend you visit the following
