1. An optical-fiber-based wireless communication system, comprising:

  • at least one service unit configured to receive signals from at least one outside network; and

    a plurality of fiber optic array cables configured to provide signals to the service unit, each fiber optic array cable having multiple reference units disposed along a length of the fiber optic array cable, each of the multiple reference units containing at least one antenna, an electrical-to-optical (E/O) converter, and an optical-to-electrical (O/E) converter,wherein the at least one service unit is configured to;

    cause a radio frequency (RF) signal to be transmitted from one or more of the at least one antennas in the multiple reference units to form a wireless coverage area associated with the reference unit;

    receive a corresponding signal from at least three of the multiple reference units indicative of a distance between each of the respective reference units and an object in the wireless coverage areas associated with the respective reference units; and

    process the corresponding signals received from the plurality of the multiple reference units to determine a location of the object in at least two dimensions.
