Title
(EN) WHITESPACE CHANNEL ALLOCATION
(FR) ATTRIBUTION DE CANAUX D'ESPACE BLANC
Abstract
(EN) The present invention relates to a system for allocating unused radio frequency spectrum channels with the TV White space frequency band. A spectrum manager is arranged to allocate available white space channels to requesting wireless access point devices. When more than two devices request channels, the spectrum manager determines any mutual interference that may be caused by those devices and allocates channels so as to minimise mutual interference. Where there are more requesting devices than available channels, the spectrum manager is arranged to auction the channels until the demand is equal to the available channels.
(FR) La présente invention porte sur un système d'attribution de canaux du spectre radiofréquence inutilisés dans la bande de fréquences d'espace blanc de télévision. Un gestionnaire du spectre est conçu pour attribuer des canaux d'espace blanc disponibles à des dispositifs de point d'accès sans fil demandeurs. Quand plus de deux dispositifs demandent des canaux, le gestionnaire du spectre détermine tout brouillage mutuel qui peut être provoqué par ces dispositifs et attribue des canaux de manière à réduire au minimum le brouillage mutuel. Quand il existe davantage de dispositifs demandeurs que de canaux disponibles, le gestionnaire du spectre est conçu pour mettre aux enchères les canaux jusqu'à ce que la demande soit égale aux canaux disponibles.
