15 Claims

1. A communications system, comprising:

a server, including:

one or more radio head interface modules; and

a call processing software module, the one or more radio head interface modules adapted to communicate with the call processing software module;

wherein the call processing software module performs modulation and demodulation of voice and data streams using one or more air interface protocols; and

a radio head unit coupled to the radio head interface module over one or more transport mediums;

wherein the radio head unit communicates with one or more subscriber units using the one or more air interface protocols;

wherein the radio head interface module receives air interface protocol parameters from the call processing software module for one or more communication channels;

wherein the radio head interface module reconfigures itself for one or more communications channels, based on the air interface protocol parameters;

wherein air interface protocol parameters include at least one of a protocol reconfiguration indicator, modulation protocol assignment parameters, and a timing trigger;

wherein the timing trigger is a designated time; and

wherein the designated time correlates to a time count internal to the radio head interface module;

wherein radio head interface module further comprises:

a global positioning system receiver, wherein the time count internal to the radio head interface module is synchronized with an output signal from the global positioning system receiver.
