Data transport in a virtualized distributed antenna system
First Claim
1. A system for routing signals in a Distributed Antenna System, the system comprising:
- a plurality of local Digital Access Units (DAUs) located at a local location, each of the plurality of local DAUs being coupled to each other and operable to route signals between the plurality of local DAUs, wherein each of the plurality of local DAUs includes one or more Base Transceiver Station (BTS) radiofrequency connections, each of the plurality of BTS radiofrequency connections being operable to be coupled to one of one or more sectors of a BTS; and
a plurality of remote DAUs located at a remote location, wherein the plurality of remote DAUs are coupled to each other and operable to transport signals between the plurality of remote DAUs, and wherein the plurality of remote DAUs are connected to the plurality of local DAUs.

Abstract
A system for routing signals in a Distributed Antenna System includes a plurality of local Digital Access Units (DAUs) located at a Local location. Each of the plurality of local DAUs is coupled to each other and operable to route signals between the plurality of local DAUs. Each of the plurality of local DAUs includes one or more Base Transceiver Station (BTS) RF connections. Each of the plurality of BTS RF connections is operable to be coupled to one of one or more sectors of a BTS. The system also includes a plurality of remote DAUs located at a Remote location. The plurality of remote DAUs are coupled to each other and operable to transport signals between the plurality of remote DAUs.
