One embodiment is directed to a distributed antenna system (DAS) for use with one or more base stations. The DAS comprises a plurality of remote antenna units, one or more donor units, and one or more transport units. The DAS is configured to communicatively couple each donor unit to at least one of the transport units and to communicatively couple each transport unit to at least one of the donor units. The DAS is configured so that all active downlink digital processing for producing the downlink transport signals transmitted from the transport units to the remote antenna units is performed by the donor units and the transport units. The DAS is configured so that all active uplink digital processing of the uplink transport signals received by the transport units from the remote antenna units is performed by the donor units and the transport units.
