FIG. 5 is next a simplified block diagram of an example RRH 526. As shown, the example RRH includes at least one baseband port 528 for coupling with at least one baseband unit as noted above, and a plurality of antenna ports 530 for coupling with cell site antennas as noted above. In an example arrangement, without limitation, the baseband port could be a multi-fiber-cable port for connecting with a multi-fiber cable that connects in turn with the baseband unit. Each fiber could carry a different channel according its connection (e.g., by way of the MUX/DEMUX) 440) to a particular channel card of the BBU. Further, by way of example, the RRH is shown including eight antenna ports for coupling with cell site antennas or antenna systems, although an example RRH could just as well have a different number of antenna ports. Each antenna port could be configured to carry one or more channels. An example RRH such as this may be housed in a unitary housing, which could be configured for mounting on an antenna tower or elsewhere at a cell site.
