Abstract

An apparatus for mobile device location has a primary device. The primary device is configured to transmit a first signal to a secondary device at a first transmit power level, and to receive a response signal indicative of a quality indicator of the first signal as received by the secondary device. The primary device is further configured to determine a second transmit power level based on the quality indicator; transmit a second signal to the secondary device at the second transmit power level; and based on the filtered transmit power level The average determines the distance between the primary device and the secondary device.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Application Serial No. 61 / 923,857, filed January 6, 2014, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0003] One or more embodiments relate to an apparatus and method for determining a distance between two wireless devices based on radio signal parameters. Background technique [0004] Mobile devices are often configured to wirelessly exchange data with other nearby media devices. For example, a cell phone can be wirelessly connected to a headset, or a laptop computer can be wirelessly connected to a printer. Alternatively, a phone or tablet can be wirelessly connected to the speaker for streaming music. For example, the OnBeatXtreme made by JBL TM A speaker docking station is an embodiment of such a speaker that can be connected wirelessly to a mobile device. Communications between wireless devices within an in...
