Abstract

A method and system for the networking of radio transceivers is disclosed. The system includes a source transceiver with a source address, and a destination transceiver with a destination address. A router gateway includes a first interface in communication with the source transceiver and a second interface in communication with the destination transceiver, and interconnections between the two are defined in a routing table. A network signaling system independent of the respective radio transmission and receipt systems enables communication between the source transceiver and the destination transceiver.
