Abstract (en)
[origin: WO9301665A1] A personal communication system (10) comprises a plurality of transceiver stations (12, 14, 16, 18) providing voice communication capability between one or more portable radiotelephones (20, 22, 24) and a telephone network (30). One or more of the transceiver stations (12, 14, 16, 18) is further capable of storing a localized information data base and of transmitting the same in response to a request for such transmission being received from one of the portable radiotelephones (20, 22, 24) communicating therewith. The portable radiotelephone (20, 22 or 24) communicating therewith is capable thereafter of receiving at least a first portion of the transmitted localized information data base and of presenting the same to the radiotelephone subscriber.
