Claim Text:
1. A method of calibrating a station in a communications network comprising at least two antennas configured to operate together for both transmitting and receiving modes, and a plurality of radio circuits configured to transmit and receive via said antennas in a time division duplex (TDD) communication protocol, the method comprising: determining, by a processor, a phase setting difference between transmit and receive antenna patterns of said at least two antennas operating together, if the signals received from another station have a minimum signal strength then the receive antenna patterns are measured, and the transmit antenna patterns are determined based on a transmit data rate to another station; using, by the processor, said phase setting difference to determine one or both of: a relative amplitude setting for transmit antenna patterns, and a relative amplitude setting for receive antenna patterns; and calibrating the station by adjusting, by the processor, one or both of: each transmit antenna pattern transmitted by the station by the relative amplitude setting for the transmit antenna patterns, and each receive antenna pattern received by the station by the relative amplitude setting for the receive antenna patterns.
