Abstract: A radio communication system includes a polling central station and a number of remote stations. Each remote station is identified by a unique address transmitted from the central station preceding a message intended for such remote station. Each of the remote stations also may be programmed to respond to the address of a "partner" station in addition to responding to its own address. The "partner" station address is employed whenever one of the remote stations is located such that a transmission link problem exists between such station and the central station polling station. When this condition exists, the station which has difficulty communicating directly with the central station is provided with a new address and no longer is responsive to the address of messages transmitted to it from the central station.
