Systems, components, and methods for providing location services for mobile/wireless client devices in distributed antenna systems using additional signal propagation delay

A distributed antenna system, comprising:

• a plurality of remote antenna units (RAU) each configured to communicate received downlink radio-frequency (RF) communications signals wirelessly to client devices and configured to receive uplink RF communications signals wirelessly from the client devices;
• head end equipment (HEE) configured to:
• receive the downlink RF communications signals from a base station and distribute the received downlink communication RF signals over a plurality of downlink communications paths comprising a plurality of downlink communications medium each coupled to one of the plurality of remote antenna units (RAUs);
• and
• receive uplink RF communications signals over a plurality of uplink communications paths comprising a plurality of uplink communications medium each coupled to one of the plurality of RAUs;
• and
• at least one of additional uplink delay component provided in one or more of the uplink communications paths to increase a signal propagation delay of the uplink RF communications signals such that each of the plurality of uplink communications paths has a unique actual signal propagation delay to uniquely identify the plurality of RAUs from the actual signal propagation delay of the uplink RF communications signals.
