DÉTECTION DE MOUVEMENT AU MOYEN D'UN CONTRÔLEUR CENTRAL ET EN UTILISANT DES INFORMATIONS DYNAMIQUES DE FORMATION DE FAISCEAU

摘要

In a general aspect, motion is detected using wireless signals. In one example, a wireless signal transmitted through a space from a first wireless communication device is received at a second wireless communication device. Dynamic beamforming information is based on the wireless signal. The second wireless communication device uses the dynamic beamforming information to detect motion in the space, or transmits the dynamic beamforming information to the first wireless communication device for use in detecting motion in the space.
