1. A method for charging an electronic device, the method comprising:

  • receiving, by an antenna of the electronic device, a wireless signal, wherein;

    a receiver chip is embedded in the electronic device and connected to the antenna, the receiver chip including a switch and rectifier circuitry, andthe switch is configured to route the wireless signal to either the rectifier circuitry or a transceiver of the electronic device;

    in response to determining that the antenna is receiving power above a threshold level from the wireless signal, routing, via the switch, the received wireless signal to the rectifier circuity, the rectifier circuitry being configured to convert the wireless signal into usable energy for charging a battery of the electronic device connected to the rectifier circuitry, wherein the wireless signal routed to the rectifier circuitry is received from a wireless power transmitter positioned in a near-field distance from the antenna; and

    in response to determining that the antenna is not receiving power above the threshold level from the wireless signal, routing, via the switch, the received wireless signal to the transceiver, the transceiver being configured to process the wireless signal as data from the wireless power transmitter or another electronic device, wherein the transceiver is not connected to the battery of the electronic device or the rectifier circuity of the receiver chip.
