1. A method of wireless power transmission, comprising:

  • at a wireless power transmitter having a communications component, a plurality of antenna elements configured to transmit power waves, and at least one processor;

    performing a test of communications with a wireless power receiver, the test of communications comprising;

    sending, by the communications component, a first message to the wireless power receiver;

    receiving, by the communications component, a second message from the wireless power receiver in response to the first message; and

    comparing, by the at least one processor, one or more operational metrics associated with the first and second messages with respective expected values for each of the one or more operational metrics to determine an outcome for the test;

    sending, by the communications component, a report to a remote server that includes the determined outcome for the test;

    receiving information from the remote server to authenticate the wireless power receiver, wherein authentication of the wireless power receiver is distinct and separate from the test of communications; and

    after sending the report, stopping performance of the test and starting a normal operation of the wireless power transmitter in which the wireless power transmitter transmits, by at least some of the plurality of antennas, power waves that converge to form a constructive interference pattern in proximity to a location of the wireless power receiver,wherein the wireless power receiver uses energy from the constructive interference pattern to charge or power an electronic device that is coupled with the wireless power receiver.
