Title
(EN) MICROWAVE REFLECTOR LINK, AND CDMA-SPREAD SPECTRUM REFLECTOR APPARATUS FOR REDUCTION OF UNMODULATED AMBIENT BLOCKERS IN REFLECTED DATA LINKS
(FR) LIAISON DE RÉFLECTEUR À HYPERFRÉQUENCES ET APPAREIL DE RÉFLECTEUR À SPECTRE ÉTALÉ CDMA PERMETTANT UNE RÉDUCTION DES BLOQUEURS AMBIANTS NON MODULÉS DANS DES LIAISONS DE DONNÉES RÉFLÉCHIES
Abstract
(EN) A system, apparatus and method are disclosed for communicating between a short range wireless (WLAN) user device, such as a wearable, phone, or tablet, with a base station. Traditional low power communication (e.g., WLAN, WiFi, Bluetooth, cellular links, etc.) involve an inefficient amplification process of a signal from the WLAN user to the base station, whereby significant power must be expended in the WLAN user device making it unsuitable in many applications. A reflector link paradigm is disclosed in which the user device communicates by modulating the extent of signal reflected back to the base station. An enhanced reflector is also disclosed which overcomes adverse effects of ambient reflections.
(FR) L'invention concerne un système, un appareil et un procédé permettant de communiquer entre un dispositif utilisateur sans fil (WLAN) à courte portée, tel qu'un téléphone portable ou une tablette, avec une station de base. Les communications classiques de faible puissance (par exemple, un réseau WLAN, Wi-Fi, Bluetooth, des liaisons cellulaires, etc.) impliquent un procédé d'amplification inefficace d'un signal entre l'utilisateur WLAN et la station de base de telle sorte qu'une quantité significative d'énergie doive être utilisée dans le dispositif d'utilisateur de réseau WLAN, le rendant inapproprié dans de nombreuses applications. L'invention concerne un paradigme de liaison de réflecteur selon lequel le dispositif utilisateur communique par modulation de l'étendue du signal réfléchi en retour vers la station de base. L'invention concerne également un réflecteur amélioré qui permet de surmonter les effets néfastes des réflexions ambiantes.
