POINT-TO-MULTIPOINT MICROWAVE COMMUNICATION
A microwave communication system may include subscriber stations in communication with a base station. The stations may include time duplex circuitry normally found in wireless local area networks (WLANs). Signals normally routed through antennas associated with such circuitry instead are routed through circuitry to perform frequency conversion to and from microwave communications frequencies, for communications over microwave links between the subscriber stations and the base station. In some embodiments the wireless circuitry is configured for multiple input multiple output (MIMO) operation with one antenna port dedicated for transmission of data and one antenna port dedicated to reception of data.
1 . A communication device for a microwave communication system, comprising:
wireless communication circuitry including at least two antenna ports, with at least one of the two antenna ports configured for transmission only and at least one other of the two antenna ports configured for reception only;
at least one transmit mixer coupled to the at least one antenna port configured for transmission, to upconvert a signal from the at least one antenna port configured for transmission to provide a transmit signal at microwave communication frequencies; and
at least one receive mixer coupled to the at least one other antenna port configured for reception, to downconvert a received signal at microwave communication frequencies.
