DISTRIBUTED ANTENNA COMMUNICATIONS SYSTEM
First Claim
1. A distributed antenna system comprising:
- a hub to receive a plurality of downlink transceiver signals output from a plurality of transceiver units and to send a plurality of uplink transceiver signals to the plurality of transceiver units, the plurality of downlink transceiver signals having overlapping frequencies and containing different communication content; and
a plurality of distributed antenna units, each of which is located at a respective location that is remote from the hub;
wherein the hub is configured to route a respective downlink transport signal to each of the plurality of distributed antennas, wherein each of the downlink transport signals is derived from one of the plurality of downlink transceiver signals received at the hub;
wherein each of the distributed antenna units is configured to transmit a respective downlink radio frequency signal derived from the downlink transport signal that is routed to that distributed antenna unit;
wherein each of the distributed antenna units is configured to receive at least one uplink radio frequency signal and to transmit to the hub a respective uplink transport signal that is derived from the at least one uplink radio frequency signal received at that distributed antenna unit; and
wherein the uplink transceiver signals sent to the plurality of transceiver units are derived from the uplink transport signals received at the hub.

Abstract
One embodiment is directed to a distributed antenna system that comprises a hub to receive a plurality of downlink transceiver signals output from a plurality of transceiver units and to send a plurality of uplink transceiver signals to the plurality of transceiver units. The plurality of downlink transceiver signals has overlapping frequencies and contains different communication content. The distributed antenna system further comprises a plurality of distributed antenna units, each located at a respective a remote location. The hub is configured to route a respective downlink transport signal to each of a plurality of distributed antennas, wherein each of the downlink transport signals is derived from one of the plurality of downlink transceiver signals received at the hub. Each of the distributed antenna units is configured to transmit a respective downlink radio frequency signal derived from the downlink transport signal that is routed to that distributed antenna unit.
