Title (EN) MECHANISM FOR PROXIMITY DETECTION BASED ON WI-FI SIGNALS
(FR) MÉCANISME POUR UNE DÉTECTION DE PROXIMITÉ SUR LA BASE DE SIGNAUX WI-FI
Abstract: front page image
(EN)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.
(FR)L'invention porte sur un mécanisme de détection de proximité sur la base de signaux Wi-Fi. Un procédé des modes de réalisation de l'invention comprend la détermination de la puissance d'un ou plusieurs signaux communiqués entre une ou plusieurs antennes d'un premier dispositif et deux ou plus de deux antennes d'un second dispositif. Le ou les signaux sont associés à un paquet de diffusion. Le procédé comprend en outre la détermination d'une proximité du premier dispositif et du second dispositif sur la base de la puissance déterminée du ou des signaux.
