1. A system comprising:
a first fronthaul interface including a plurality of first digital multiplexing units (DMUs), wherein each first DMU of the plurality of first DMUs is in communication with a plurality of digital remote units (DRUs) that provide radio coverage in a given geographic location associated with the first DMU that is different from one or more geographic locations associated with other first DMUs of the plurality of first DMUs, is in communication with at least one other first DMU of the plurality of first DMUs, and is configured to:
receive a plurality of first carriers, and configuration information for the carriers from a first baseband unit (BBU) and from one or more other first DMUs of the plurality of first DMUs;
extract a first subset of the plurality of first carriers, and configuration information for the carriers associated with the plurality of DRUs associated with the first DMU;
aggregate the first subset of the plurality of first carriers, and configuration information for the carriers into a first stream; and
route the first stream to one or more DRUs of the plurality of DRUs.
