Abstract

An electronic device includes a first antenna for transmitting a signal to a remote communication node and a second antenna for receiving a RF power signal from a remote wireless charger. The device includes a RF to DC converter connected to second antenna to convert the RF power signal to direct current power. DC power management circuitry is connected to the RF to DC converter to supply the direct current power to at least one of a battery or a device circuit. The electronic device includes a controller that monitors an output level of the transmission signal being transmitted to the remote communication node, determines whether the output level has met a predetermined threshold level during a transmission cycle, and causes the second antenna to be turned off after the output level has met or exceeded the predetermined threshold level during a predetermined number of transmission cycles.
