Title (EN) PROTOCOL FOR SWITCHING BETWEEN CHANNELS IN TYPE 2 AGILE RADIO
(FR) PROTOCOLE POUR COMMUTER ENTRE DES CANAUX DE RADIOS AGILES DE TYPE 2
Abstract:
(EN) The system (400), apparatus (401.j), and method (100) of the present invention provide a way to expand and contract the available wireless channels opportunistically by optimally switching the OFDM carriers. The present invention employs a spectrum occupancy information element (200) and a local spectrum occupancy database (505) respectively for exchange of spectrum occupancy information with other devices and persistent storage of spectrum occupancy information, both of which enable seamless working of agile radios in such a way that their transmission capacity is greatly enhanced.
(FR) L'invention concerne un système (400), un appareil (401.j), et une méthode (100) permettant d'étendre et de réduire les canaux sans fil disponibles de manière avantageuse, par une commutation optimale des porteuses MROF. L'invention fait appel à un élément d'information d'occupation de spectre (200) et à une base de données locale d'occupation de spectre (505) pour échanger des informations d'occupation de spectre avec d'autres dispositifs, et pour effectuer un stockage persistant d'informations d'occupation de spectre, ces éléments permettant tous deux un fonctionnement sans interruption de radios agiles, de sorte que leur capacité de transmission se trouve considérablement accrue.
