Abstract
Disclosed is a method of wireless power transfer to at least one wireless station connected to a network from an energy signal transfer apparatus operating in the same frequency band as a wireless local area network (WLAN). The method includes: receiving an energy transfer request from a first wireless station connected to the network; calculating the direction of energy signal transfer in response to the energy transfer request; and sending an energy signal to the first wireless station in the calculated direction of energy signal transfer for the duration of energy transfer. The energy signal transfer apparatus allows for power transfer without causing interference with data transmission on a channel where data transmission occurs, by transferring energy only in the direction of stations requesting energy transfer by beamforming technology.
