Wireless charging of multiple wireless devices using RF (radio frequency) engergy

Abstract:

RF (radio frequency) charging access points charge IoT (Internet of things) devices. RF charging service is advertised through periodically broadcast beacons. A MU-MIMO group or other group is formed from a plurality of stations connected to the access point for RF charging. RF packets are transmitted to stations in the MU-MIMO group, each station including RF charging circuitry to harvest reusable energy from the RF packets.
