  • Patent number: 6178334
    Abstract: This disclosure relates to a communications network including a base station and two or more distributed cells which are remote from the base station. The cells are coupled to the base station by transmission mediums which may, for example, be cable, fiber, and/or air. Between the base station and each cell, there is a time delay or transmission time, between the time when a communication that is received at one of the two is transmitted to and is received by the other of the two. The time delays of the two cells are unique or distinct one from the other. The network includes a time responsive system which is responsive to the time delay for a communication between the base station and one of the cells. Since the time delays are distinctive, the time responsive system identifies the cell associated with the communication. The time delays of the cells may be inherent in the circuitry and transmission mediums between the base station and the cells.
