1. A method comprising:

  • causing a first transmitter to provide electrical power to a receiver via a first wireless resonant coupling link using a first oscillation frequency;

    determining that a handover condition is met; and

    in response to determining that the handover condition is met, facilitating a handover to a second transmitter, wherein the handover comprises;

    engaging in a phase-determination process to determine a first phase at which the first transmitter should provide electrical power to the receiver and a second phase at which the second transmitter should provide electrical power to the receiver;

    causing the first transmitter to provide electrical power to the receiver at the determined first phase while also causing the second transmitter to provide electrical power to the receiver at the determined second phase, wherein the second transmitter provides electrical power to the receiver at the determined second phase via a second wireless resonant coupling link using a second oscillation frequency; and

    after causing the first transmitter to provide electrical power to the receiver at the determined first phase while causing the second transmitter to provide electrical power to the receiver at the determined second phase, causing the first transmitter to no longer provide electrical power to the receiver and causing the second transmitter to continue to provide electrical power to the receiver.
