Radio personal communications system and method for selecting a frequency for use in communications between a base station and a cellular terminal
First Claim
1. A telephone base station for connecting a wire telephone network to a cellular terminal within a base region of a wide area cellular network which uses a plurality of frequencies within a cellular network spectrum, comprising:
- a portable housing;
wire telephone network connecting means extending within said portable housing;
radio transceiving means in said portable housing;
external frequency indicating signal receiving means within said portable housing for receiving an external frequency indicating signal from said wire telephone network via said wire telephone network connecting means; and
means, in said portable housing, responsive to said external frequency indicating signal, for operating said transceiving means at a selected frequency corresponding to the received frequency indicating signal.

Abstract
Transceiver frequency and optionally power level are allocated to a radio personal communications system which includes a base station connected to a wire telephone network and a cellular terminal operating within a region of a wide area cellular network to minimize interference between communications over the wide area cellular network and communications between the base station and the cellular terminal. The same cellular terminal may thus be used to communicate over the lower cost wire network when within range of the base station and over the wide area cellular network otherwise. The frequency for communications between the cellular terminal and the base station are optionally assigned by the operator of the wide area cellular network so appropriate frequencies and power levels can be assigned for base stations, to minimize same channel interference with the wide area cellular network.
