    Abstract: Embodiments described herein provide for a distributed antenna system including a host unit and an active antenna unit (AAU). The AAU is configured to wirelessly communicate with, and to receive uplink radio frequency (RF) signals from, one or more wireless devices. The AAU is further configured to sample the uplink RF signals to generate digitized RF data. The AAU includes an Ethernet interface for receiving Internet Protocol (IP) formatted data from an IP device coupled to the Ethernet interface. The AAU is configured to transport the digitized RF data and the IP formatted data over a transport signal to the host unit, the transport signal including a plurality of bits. The AAU is configured to adaptively adjust the number of bits that are allocated to the digitized RF data and the number of bits that are allocated to the IP formatted data.
