Abstract
A portable data terminal includes at least two communication transceivers having different operating characteristics, one for conducting data communications on a wired subnetwork and one for conducting data communications on a wireless subnetwork. A communication processor converts data received by the communication transceivers to a predetermined format for a base module and converts data in a predetermined format from the base module to a format for transmission by a selected one of the first and second communication transceivers, thereby isolating the base module from differing characteristics of the transceivers. The communication processor is arranged to relay communications received by one transceiver for re-transmission by the other transceiver and to transfer communications from one subnetwork to the other, without activating the base module.
