A dynamically reconfigurable communications system is presented. The communications system comprises a server, including one or more radio head interface modules, a call processing software module, and a radio head unit coupled to the radio head interface module over one or more transport mediums. The one or more radio head interface modules adapted to communicate with the call processing software module, wherein the call processing software performs modulation and demodulation of voice and data streams using one or more air interface protocols. The radio head unit communicates with one or more subscriber units using the one or more air interface protocols. The radio head interface module receives power level adjustment parameters from the call processing software module for one or more logical channels and reconfigures the signal gain of one or more communications channels based on the power level adjustment parameters.
