Abstract: A method and apparatus for beamforming training using frames is provided. A device generates a frame comprising header data and beamforming data. The beamforming data is organized into units of beamforming training (TRN) fields. The header data comprises numbers indicating: a first type of TRN fields in each of the units of the beamforming data, to be transmitted using same antenna settings used for the header data; a second type of TRN fields in each of the units to be transmitted using different antenna settings than used for the header data; and how the first type of TRN fields are organized into respective groups of the second type of TRN fields in each of the units that are to be consecutively transmitted using same respective antenna settings, the respective antenna settings changing with each successive group of the third number of the second type of TRN fields.

Abstract: A broadband phased array antenna system is set forth comprising a support member; an antenna array mounted to the support member, the antenna array having a plurality of uniformly excited hybrid radiating elements arranged in a symmetric array on a substrate; a baseband controller mounted to the support member; a radio controller mounted to the support member for modulating and demodulating signals between the baseband controller and antenna array; and a communications interface for removably connecting and disconnecting the antenna system. In one aspect, the antenna array comprises a substrate; a plurality of uniformly excited hybrid radiating elements arranged in a symmetric array on the substrate; a hybrid feeding network for transmitting RF-signals to the hybrid radiating elements; and artificial materials surrounding opposite sides of the symmetric array for suppressing edge scattered fields and increasing gain of the antenna system.

Abstract: A wireless communication assembly stores configuration parameter sets for predefined spectral masks, including: a single channel mask for a base channel bandwidth, and defining target power levels for each of a base in-band bandwidth, base transition bandwidths, and a base floor bandwidth; and a bonded channel mask for a multiple of the base channel bandwidth, and defining target power levels for each of a bonded in-band bandwidth equivalent to the sum of the base in-band bandwidth and the base channel bandwidth, and bonded transition and floor bandwidths that are multiples of the base transition and floor bandwidths. A radio controller selects predefined channels each having the base channel bandwidth, for transmitting data to a recipient station; retrieves selected one of the configuration parameter sets based on the number of selected channels; and applies the selected configuration parameter set to data for transmission to the recipient station.
