1. A receiver device comprising:

  • a communications radio configured to;

    send a coded signature signal to a wireless power transmitter, wherein the coded signature signal includes information identifying the receiver device; and

    send a set of user-defined restrictions to the wireless power transmitter after the receiver device has been authorized to receive wireless power from the wireless power transmitter; and

    at least one antenna configured to receive two or more radio frequency (RF) power waves from the wireless power transmitter that converge to form controlled constructive interference, wherein;

    the wireless power transmitter transmits the two or more RF power waves to the receiver device after determining that none of the user-defined restrictions in the set of user-defined restrictions are present at the receiver device;

    the two or more RF power waves are transmitted with one or more RF power wave characteristics that are determined based on information received from the receiver device; and

    energy from the two or more RF power waves received by the at least one antenna is used to power the receiver device.
