Abstract

The disclosure is directed to a wireless communications device. In an embodiment, the wireless communications device comprises a phased antenna array comprising a plurality of antennas, a transceiver operatively coupled to the phased antenna array and configured to control the plurality of antennas and an antenna weight vector (AWV), a memory storing a spherical zoning map, and a beam controller configured to control the transceiver by setting the AWV for each antenna of the plurality of antennas.

Description

technical field [0001] The present disclosure relates to wireless communications, and more particularly to 60GHz wireless communications. Background technique [0002] Wireless communication in the 60 GHz band is characterized by a large path loss due to its high frequency. Therefore, the gain of the transmit antenna and the receive antenna must be increased to meet the link budget requirements. High-gain antennas direct a relatively narrow beam of radio waves in a specific direction. For this reason, a phased antenna array is installed in order to perform adaptive beamforming. [0003] The 60GHz band can be used for wireless personal area networks (WPAN). As a receiver device (such as a laptop, tablet, camera, cell phone, PDA, etc.) moves from a first location in a room to a second location, it may have to switch from one beam to another. However, the receiver does not know which directions the adjacent / overlapping beams are pointing. Therefore, the receiver needs to d...
