Abstract:
Post-amble processing of a beam forming packet may utilize different sector rotation speeds at different wireless communication devices. Power measurements may be captured for individual sectors of an antenna array with respect to a complete rotation of antenna sectors at another wireless communication device. The power measurements may be evaluated to identify a sector for directing a millimeter wave beam between the different wireless communication devices. In some embodiments, a second packet may be transmitted back using the identified sector to determine another sector for directing the millimeter wave beam between the different wireless communication devices.
