DC CAFCFirst Claim
1. A system for transporting wireless communications, comprising:
- at least one Digital Access Unit (DAU);
wherein the at least one DAU comprises at least one signal source interface to communicatively couple the at least one DAU to at least one signal source; and
wherein the at least one DAU is configured to receive a plurality of downlink signals from the at least one signal source; and
a plurality of remote units;
wherein the at least one DAU further comprises at least one remote interface configured to communicatively couple the at least one DAU to the plurality of remote units;
wherein the at least one DAU is configured to receive a plurality of uplink signals from the plurality of remote units; and
one or more delay compensation merge units configured to delay signals transmitted from or received by each of the plurality of remote units.

Abstract
A system for routing signals in a Distributed Antenna System includes a plurality of Digital Access Units (DAUs) and a plurality of Digital Remote Units (DRUs). The plurality of DAUs are coupled and operable to route signals between the plurality of DAUs. The plurality of DRUs are coupled to the plurality of DAUs and operable to transport signals between DRUs and DAUs. The system also includes a plurality of Base Transceiver Stations (BTS) and a plurality of Base Transceiver Station sector RF connections coupled to the plurality of DAUs and operable to route signals between the plurality of DAUs and the plurality of Base Transceiver Stations sector RF port connections. The system further includes one or more delay compensation merge units operable to delay signals transmitted from or received by each of the plurality of DRUs.
