Title
(EN) OPERATING A MODAL ANTENNA SYSTEM FOR POINT TO MULTIPOINT COMMUNICATIONS
(FR) FONCTIONNEMENT D'UN SYSTÈME D'ANTENNE MODALE POUR DES COMMUNICATIONS POINT À MULTIPOINT
Abstract
(EN)
Systems and methods for point to multipoint communications are provided. In one example, a system includes one or more modal antennas. Each modal antenna is configured to operate in a plurality of modes. The system can include a transceiver configured to communicate with a plurality of client devices over a wireless communication medium via the one or more modal antennas over a plurality of frames. The system can include one or more control devices configured to control the operation of the one or more modal antennas. For each of the plurality of frames communicated to one of the plurality of client devices, the one or more control devices are configured to determine a selected mode of the plurality of modes to communicate during the frame and to operate at least one of the one or more modal antennas in the selected mode during the frame.

L'invention concerne des systèmes et des procédés de communication point à multipoint. Dans un exemple, un système comprend une ou plusieurs antennes modales. Chaque antenne modale est configurée pour fonctionner dans une pluralité de modes. Le système peut comprendre un émetteur-récepteur configuré pour communiquer avec une pluralité de dispositifs clients sur un support de communication sans fil par l'intermédiaire de la ou des antennes modales sur une pluralité de trames. Le système peut comprendre un ou plusieurs dispositifs de commande configurés pour commander le fonctionnement de la ou des antennes modales. Pour chaque trame de la pluralité de trames communiquées à l'un de la pluralité de dispositifs clients, le ou les dispositifs de commande sont configurés pour déterminer un mode sélectionné de la pluralité de modes pour communiquer pendant la trame et pour faire fonctionner au moins l'une de la ou des antennes modales dans le mode sélectionné pendant la trame.
