Patent ID: 8195232

Claim:
A communications module for performing radio communications functions in a cellular communications device, the communications module comprising: a plurality of logical module-to-host interfaces comprising: a module logical voice interface configured to communicatively connect to a cellular communications device logical voice interface; a module logical data interface configured to communicatively connect to a cellular communications device logical data interface; and a module logical management interface configured to communicatively connect to a cellular communications device logical management interface; a module antenna physical interface configured to physically connect to a cellular communications device antenna; a module communications physical interface configured to transmit a multiplexed output signal to the cellular communications device; a module multiplexer-demultiplexer configured to: demultiplex a signal received on the module antenna physical interface into a voice input signal, a data input signal, and a management input signal; and provide the voice input signal to the module logical voice interface, the data input signal to the module logical data interface, and the management input signal to the module logical management interface; and the module multiplexer-demultiplexer further configured to: multiplex a voice output signal from the module logical voice interface, a data output signal from the module logical data interface, and a management output signal from the module logical management interface; and provide the multiplexed output signal to the module communications physical interface.
