Abstract
A system may distribute radio networking traffic from a base station to one or more radio units in a bi-directional link. The system may transport the radio networking traffic over a digital network. The system may include a front-haul unit coupled to the radio units and in communication with the base station. The front-haul unit may encapsulate access signals from the base station within digital transport streams for transport over the digital network. The front-haul unit may multicast digital transport transmission streams to multiple radio units in a virtual cell. The digital transport streams may contain combined received access signals from multiple service providers in a neutral-host configuration. The radio units may map encapsulate incoming radio signals for return transport to the front-haul unit and then on the base station. The front-haul unit may transport data over the network to support wireless local area network service at the radio units.
