CA 2474252

A method is provided for transmitting ultrawide bandwidth signals in a network comprising a network coordinator and one or more remote devices. The available transmission time is divided into a plurality of superframes, each of which is further divided up into a beacon duration, one or more management time slots, one or more guaranteed time slots, and one or more asynchronous time slots. Each of the management time slots, guaranteed time slots, and asynchronous time slots are assigned to one of the one or more remote devices. The network coordinator sends a beacon to the one or more remote devices during the beacon duration. The device or coordinator assigned to the current guaranteed time slot sends frames of isochronous data in the current guaranteed time slot. The device or coordinator assigned to the current asynchronous time slot sends frames of asynchronous data in the current asynchronous time slot.

La présente invention concerne un procédé permettant la transmission de signaux de bande passante très large dans un réseau comportant un coordinateur de réseau et un ou des dispositifs à distance. Le temps de transmission disponible est divisé en plusieurs supertrames, dont chacun est davantage divisé en une durée de balise, un ou des créneaux de gestion, un ou des créneaux garantis, et un ou des créneaux asynchrones. Chacun des créneaux de gestion, des créneaux garantis, et des créneaux asynchrones sont affectés à un desdits un ou des dispositifs à distance. Le coordinateur de réseau envoie une balise auxdits un ou des dispositifs à distance pendant la durée de balise. Le dispositif ou le coordinateur affecte au créneau garanti actuel des trames de données isochrones dans le créneau garanti actuel. Le dispositif ou le coordinateur affecte au créneau asynchrone actuel des trames de données asynchrones dans le créneau asynchrone actuel.
