Abstract
A hybrid radio transceiver that includes one wideband receiver and multiple narrowband transmitters for use in wireless networks, having the advantage of providing lower cost but performance that is comparable to a transceiver that uses multiple narrowband transceivers. The hybrid radio transceiver provides software defined parameters to achieve flexibility in modulation and protocol types. The hybrid radio transceiver is adaptable to both capacity intensive and wide coverage applications, and supports communication links that are imbalanced in terms of data transmission capacity. The wideband receiver, of the hybrid radio transceiver, converts the RF to an IF which is digitized and passed to digital signal processors for tuning, filtering, demodulation and protocol control with eventual interface to the network. The narrowband transmitters, of the hybrid radio transceiver, use a variety of processes which include modulation in a narrowband exciter which feeds a narrowband power amplifier then combination of the signals before the antenna, or use of a multi-carrier power amplifier and low power combiner.
