First Claim
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.

Abstract
Embodiments of the disclosure relate to identifying remote units in a wireless distribution system (WDS) based on assigned unique temporal delay patterns. The WDS includes a plurality of remote units configured to communicate communications signals in signal paths. Each of the signal paths is assigned a unique temporal delay pattern. The communications signals are digitally delayed by respective delay elements based on the plurality of unique temporal delay patterns to provide delayed communications signals. A remote unit identification system analyzes a delayed communications signal to determine a respective temporal delay pattern associated within the delayed communication signal. By uniquely identifying a remote unit from which a delayed communication signal is communicated, it is possible to determine the locations client devices in the WDS, thus enabling a variety of location-based services and optimizations in the WDS.
