ABSTRACT:
A communications system dynamically reconfigurable for RF bandwidth and modulation protocols is disclosed. A server comprises one or more radio head interface modules and a call processing software module adapted to communicate with each other. The call processing software is adapted to perform modulation and demodulation of voice and data streams using one or more air interface protocols. A radio head unit coupled to the radio head interface module communicates with one or more subscriber units. The radio head interface module receives either air interface protocol configuration information, or RF signal bandwidth allocation information, from the call processing software module for one or more communication channels, the information providing a timing trigger and a protocol or bandwidth for one or more communication channels. The radio head interface module reconfigures itself for one or more communications channels, based on the change instructed by the call processing software.
