Abstract
Embodiments of the present application relate generally to wireless electronics, wireless portable electronics, wireless media presentation devices, audio/video systems, and more specifically to passive or active RF proximity detection of wireless client devices in an environment that may or may not include wireless access points. A wireless client device may be forced, triggered, or configured to broadcast a wireless scan (e.g., an active WiFi scan) that includes data (e.g., packets) that may be discovered by a wireless media device (e.g., received by RF circuitry in the media device) and information from the wireless scan may be used by the wireless media device to detect presence of the wireless client device and/or its user, to establish a wireless data communications link with the wireless client device, to determine proximity of the wireless client device to the wireless media device, and for near field communication (NFC) with the wireless client device.
