WIRELESS POWER TRANSMISSION METHOD IN ENERGY SIGNAL TRANSMISSION APPARATUS OPERATING IN SAME FREQUENCY BAND AS WIRELESS LAN IN WIRELESS POWER TRANSMISSION ENERGY HARVESTING SYSTEM AND ENERGY SIGNAL TRANSFER APPARATUS PERFORMING SAME

摘要

The present invention relates to a wireless power transmission method of at least one wireless terminal which is connected to a network in an energy signal transmission apparatus operating in the same frequency band as a wireless local area network (LAN). The wireless power transmission method comprises the steps of: receiving an energy transmission request from a first wireless terminal connected to a network; searching for a transmission direction of an energy signal by receiving the energy transmission request; and transmitting the energy signal to the first wireless terminal during an energy transmission time in the searched energy signal transmission direction. An energy signal transmission apparatus transmits energy in only a direction of the terminal requesting energy transmission by using a beam forming technique to simultaneously transmit power without interfering data transmission in a channel of performing the data transmission.;COPYRIGHT KIPO 2019
