Abstract
A mechanism is described for proximity detection based on Wi-Fi signals. A method of embodiments of the invention includes determining strength of one or more signals being communicated between one or more antennae of a first device and two or more antennae of a second device. The one or more signals are associated with a broadcast packet. The method further includes determining proximity of the first device and the second device based on the determined strength of the one or more signals.
