A communication system comprises a central service node, a plurality of base stations, and a fiber network. The central service node is configured with a baseband data system, a central RF system, and a central optical system. The base stations are each configured with a base station optical system, a base station RF system, and a base station transceiver system. The baseband data system in the central service node processes baseband data. The central RF system converts the baseband data into electronic RF data. The central optical system converts the electronic RF data into optical RF data. The fiber network exchanges the optical RF data between the central service node and the base stations. The base station optical system converts the optical RF data into the electronic RF data. The base station RF system modifies frequencies of the electronic RF data. The base station transceiver system converts the electronic RF data into wireless RF data and exchanges the wireless RF data over an air interface with customer premise equipment.
