Abstract
An apparatus includes a ping detection module that detects a ping signal transmitted from a secondary pad to a primary pad. The secondary pad is located on a mobile device and the primary pad located on a stationary WPT device, where the stationary WPT device transmits power through the primary pad to the secondary pad of the mobile device during a wireless power transfer operation. The ping signal includes a mobile device ID and the mobile device ID is unique to the mobile device. The apparatus includes an ID detection module that detects the mobile device ID from the ping signal received at the primary pad and a pairing module that pairs the stationary WPT device with the mobile device in response to detecting the mobile device ID of the mobile device.
