`
`ABSTRACT
`
`A portable data terminal includes at least two communica(cid:173)
`tion transceivers having different operating characteristics,
`one for conducting data communications on a wired sub(cid:173)
`network and one for conducting data communications on a
`wireless subnetwork. A communication processor converts
`data received by the communication transceivers to a pre(cid:173)
`determined 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 mod(cid:173)
`ule from differing characteristics of the transceivers. The
`communication processor is arranged to relay communica(cid:173)
`tions 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.
