1. A remote unit identification system for uniquely identifying a plurality of remote units in a wireless distribution system (WDS), comprising:

  • a controller configured to assign a plurality of unique temporal delay patterns to the plurality of remote units in the WDS, respectively, wherein;

    each remote unit among the plurality of remote units is configured to communicate a respective communications signal among a plurality of communications signals with a central unit in the WDS in a respective signal path among a plurality of signal paths disposed between the central unit and the plurality of remote units;

    the respective communications signal is digitally delayed by a respective delay element among a plurality of delay elements disposed in the respective signal path among the plurality of signal paths based on a respective unique temporal delay pattern assigned to the remote unit to provide a respective delayed communications signal; and

    a determination unit configured to;

    analyze at least one delayed communications signal communicated in at least one signal path among the plurality of signal paths;

    determine a unique temporal delay pattern associated with the at least one delayed communications signal; and

    identify a remote unit among the plurality of remote units communicating the at least one delayed communications signal in the at least one signal path based on the unique temporal delay pattern.
