Patent ID: 8626080

Claim:
A wireless device, comprising: a phased antenna array; a transceiver communicatively coupled to the phased antenna array; and an antenna control module communicatively coupled to the transceiver and the phased antenna array, the antenna control module operative to: initiate beam formation operations using an iterative training scheme between a first device and a second device of a wireless personal area network, communicate training signals and feedback information between the first device and the second device using only high rate physical channels, and during a beam refinement phase, iteratively determine antenna-array weight vectors for a directional transmit beam pattern for the phased antenna array of the first device using feedback information from the second device and send feedback information to the second device using the directional transmit beam pattern for the phased antenna array of the first device determined from feedback information from the second device until a determined signal to noise ratio (SNR) value for a reliable data communication is reached.
