Data transport in a virtualized distributed antenna system

Abstract

A system for routing signals in a Distributed Antenna System (DAS) includes one or more local Digital Access Units (DAUs) located at a local location and one or more remote DAUs located at one or more remote locations. Each of the one or more local DAUs includes an optical port coupled to an upstream unit. The upstream unit includes at least one of a repeater, a baseband unit, a Base Transceiver Station (BTS), or a DAU. The one or more remote DAUs are coupled to the one or more local DAUs via one or more optical cables. A distance between the local location and each of the one or more remote locations is greater than two kilometers.

What is claimed is: 
     
         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) RF connections, each of the plurality of BTS RF 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.
