A system and method for wireless activation of a target. A communication device transmits an ID associated with the target to a network operations center. The network operations center provides an activation signal to the communication device. The communication device wirelessly transmits an acoustic activation signal to a nearby activation device. The activation device is positioned proximate the target and causes a change in at least one physical property of the target. The target may be an optical media containing an electrochromic material with optical properties that change on application of an electric signal.

L'invention concerne un système et une méthode pour une activation sans fil d'une cible. L'invention concerne un dispositif de communication transmettant une ID associée à la cible, à un centre d'opérations de réseau. Ce centre d'opérations de réseau fournit un signal d'activation au dispositif de communication. Le dispositif de communication transmet sans fil un signal d'activation acoustique à un dispositif d'activation situé à proximité. Le dispositif d'activation est positionné à proximité de la cible et provoque un changement au niveau d'au moins une propriété physique de la cible. La cible peut être un support optique contenant une matière électrochromique présentant des propriétés optiques changeant lors de l'application d'un signal électrique.
