Distributed antenna communications system

A method of distributing communications comprising:

• receiving, at a hub, a plurality of downlink transceiver signals output from a plurality of transceiver units, the plurality of downlink transceiver signals having overlapping frequencies and containing different communication content;
• routing, from the hub, a respective downlink transport signal to each of a plurality of distributed antenna units, 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 plurality of distributed antenna units is located at a respective location that is remote from the hub;
• from each of the plurality of distributed antenna units, transmitting a respective downlink radio frequency signal derived from the downlink transport signal that is routed to that distributed antenna unit;
• at each of the plurality of distributed antenna units, receiving at least one uplink radio frequency signal;
• from each of the plurality of distributed antenna units, transmitting to the hub a respective uplink transport signal that is derived from the respective at least one uplink radio frequency signal received at that distributed antenna unit;
• and
• sending a plurality of uplink transceiver signals from the hub to the plurality of transceiver units, wherein the uplink transceiver signals sent to the plurality of transceiver units are derived from the uplink transport signals received at the hub.

A hub for use in a distributed antenna system, the hub comprising:

• a first interface 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 second interface to communicatively couple the hub to 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, via the second interface, 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, and wherein the distributed antenna unit transmits a respective downlink radio frequency signal derived from the downlink transport signal that is routed to that distributed antenna unit;
• wherein the hub is configured to receive via the second interface a plurality of uplink transport signals from the plurality of distributed antenna units, wherein the uplink transport signals are derived from uplink radio frequency signal received at the plurality of distributed antenna units;
• and
• wherein the hub is configured to derive the uplink transceiver signals sent to the plurality of transceiver units from the uplink transport signals received at the hub.
