| 1. A communications system, comprising:
a base station, including:
one or more radio head interface modules; and
a signal processing module, the one or more radio head interface modules adapted to communicate with the signal processing
module;
wherein the signal processing 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 one or more radio head interface modules 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 one or more radio head interface modules receives reconfiguration information from the signal processing module,
the reconfiguration information including at least one of air interface protocol parameters and bandwidth allocation information;
wherein the one or more radio head interface modules reconfigures itself for one or more communications channels, based on
the reconfiguration information;
wherein the one or more radio head interface modules further comprises:
a transmit buffer, the transmit buffer adapted to receive a data stream from the signal processing module and store the data
stream as a page of data sample;
a transmit engine;
a digital upconverter, the transmit engine adapted to transfer the page of data samples from the transmit buffer to the digital
upconverter;
a configuration management unit adapted to receive air interface protocol configuration information from the signal processing
module;
a memory adapted with digital upconverter parameters;
wherein the configuration management unit is further adapted to access the memory to lookup digital upconverter parameters
based on the reconfiguration information; and
wherein the configuration management unit is further adapted to output the digital upconverter parameters to the digital up
converter.
