RF Modems

Wireless modems provide for two way communication between devices that are able to handle serial communications.

The lower cost wireless modems provide for point-to-point communications. Some more expensive wireless modems provide for multipoint communications. The transmission includes a destination address followed by the data. Therefore, these devices have to be configured to accept this protocol.

Wireless modems are external to the portable device and have belt and battery packs that usually weigh approximately one or two pounds. These modems generally require an intelligent PDT such as a DOS compatible terminal that is able to support serial data communication.
