Method and apparatus for beamforming training in basic service set discovery

A calibration signal is transmitted from a transmitter antenna. A receiver antenna receives a loopback signal that results from an air coupling of the receiver antenna and the transmitter antenna. The loopback signal is compared to a target. If the loopback signal does not meet the target, then a gain of the calibration signal is adjusted and the loopback signal is again checked against the target. When the loopback signal meets the target, the gain is taken as a calibrated transmitter gain.

Wireless transmitter calibration

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.
