A wireless electricity access control system provides a way to authenticate access to a power network. The system provides a method for a user of a wireless energy receiver to perform an authentication action at the receiver. Upon successful authentication, the system presents an advertisement or other media file to the user. After the consumption of the media file, the energy receiver receives a shared secret and a timestamp. The energy receiver uses this information to synchronize clocks at the energy receiver and an energy transmitter such as the power network. The energy receiver then selects a frequency using the synchronized clocks, shared secret, and timestamp information for receiving wireless electricity from the energy transmitter.
