A method performed by a digital Distributed Antenna System (“DAS”) for routing aggregated carriers received by at least one digital master unit of the DAS to at least one digital remote unit of the DAS. The method includes identifying the received aggregated carriers to be transmitted to a wireless communication device located in a coverage area served by the at least one digital remote unit, and routing the identified aggregated carriers through the DAS such that the carriers are transported to said at least one digital remote unit for transmission to the wireless communication device.
