Abstract:
1. A wireless transceiver for use in a local wireless communication system having provision for operating with a foreign subscriber wireless device designed for operation with a foreign wireless communication system of a type operating with a different signal format and set of parameters from that of the local wireless system, comprising: wireless receiver circuitry to receive a signal from the wireless device; detection circuitry to determine the communication system type with which the signal is compatible; a plurality of processing circuits, each processing circuit adapted to process signals having the respective signal format and set of parameters of a particular communication system type, the plurality comprising; and channeling circuitry adapted to channel the signal when determined to be compatible with the communication system type of the foreign wireless communication system to a processing circuit adapted to process signals having the different signal format and set of parameters of the foreign wireless communication system; converting circuitry adapted to convert signals having the different signal format and set of parameters of the communication system type of the foreign wireless communication system into a structure suitable for normal processing by the local wireless communication system, wherein the converting circuitry comprises: a first processing circuit adapted to convert GSM signals; a second processing circuit adapted to convert TDMA signals; a third processing circuit adapted to convert FDMA signals; and a fourth processing circuit adapted to convert PCS signals.
