Point-to-multipoint microwave communication

摘要

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.

主权项

1. A subscriber unit communication device for a microwave communication system, comprising:
wireless subscriber unit circuitry including an antenna port, the wireless subscriber unit circuitry providing for time duplexed communications through the antenna port; a first transmit/receive switch coupled to the antenna port of the wireless subscriber unit circuitry by way of a wired coupling; a second transmit/receive switch; at least one transmit mixer coupled to upconvert a signal from the first transmit/receive switch to microwave communication frequencies, the at least one transmit mixer in a first signal path between the first transmit/receive switch and the second transmit/receive switch; and at least one receive mixer to downconvert a received signal from microwave communication frequencies, the at least one receive mixer in a second signal path between the second transmit/receive switch and the first transmit/receive switch; wherein the wireless subscriber unit circuitry is coupled to components of a subscriber system by way of a wired Ethernet connection.
