Abstract
An authentication between a wireless charger and a device configured to receive wireless energy from the wireless charger includes establishing a wireless data channel between the wireless charger and the device. An authentication challenge signal is driven onto a transmit charging coil of the wireless charger and a receive charging coil of the device is configured to receive the authentication challenge signal. The device sends an authentication response signal to the wireless charger based at least in part on the authentication challenge signal.
Claims1
A system comprising:
- a charger comprising:
- a transmit charging coil to deliver wireless energy in a first frequency range;
- a first wireless communication interface configured for communication in a
- second frequency range;
- and
- first processing logic coupled to drive the transmit charging coil and coupled to the first wireless communication interface, wherein the charger is configured to drive an authentication challenge signal onto the transmit charging coil and transmit a data query with the first wireless communication interface;
- and
- a device comprising:
- a receive charging coil configured to receive the wireless energy from the transmit charging coil;
- a second wireless communication interface configured to transmit a data response to the first wireless communication interface in response to receiving the data query;
- and
- second processing logic coupled to the second wireless communication interface, wherein the device is configured to generate an authentication response signal in response to receiving the authentication challenge signal.
