(FR) PROCÉDÉ DE DÉTECTION DE PORTEUSE VIRTUELLE QUI SÉPARE LE PLAN DE COMMANDE DU PLAN DE DONNÉES
Abstract:
(EN) To address M2M (Machine to Machine), IoT (Internet of Things), energy management, sensor applications, and the like, low-power Wi-Fi is intended to leverage the mass-market WLAN infrastructure for reliable, consistent, and stable access to Internet and "cloud" services. For IEEE 802.11ax OFDMA modes, even when a device transmits a 2 MHz signal, the device is required to first transmit a legacy preamble at 20 MHz. Transmission of this legacy preamble provides coexistence compatibility with legacy devices. This drastically limits the power savings that can achieved if a narrow band mode is defined which is also able to remove the restriction of first having to transmit the legacy preamble at 20MHz. Thus, mechanisms to allow future LP devices to coexist with legacy devices required.
(FR) Pour faire face aux machines M2M (machine à machine), à l'IoT (Internet des objets), la gestion d'énergie, les applications de capteur et similaires, l'invention porte sur dispositif Wi-Fi de faible puissance destiné à tirer parti de l'infrastructure WLAN de marché de masse pour un accès fiable, cohérent et stable à des services Internet et « en nuage ». Pour les modes OFDMA IEEE 802.11ax, même lorsqu'un dispositif transmet un signal de 2 MHz, le dispositif est nécessaire pour transmettre d'abord un préambule existant à 20 MHz. La transmission de ce préambule existant fournit une compatibilité de coexistence avec des dispositifs existants. Ceci limite considérablement les économies d'énergie pouvant être réalisées si un mode à bande étroite est défini, ce qui permet également de supprimer la restriction de devoir d'abord transmettre le préambule existant à 20 MHz. Ainsi, des mécanismes pour permettre à des futurs dispositifs LP de coexister avec des dispositifs existants sont nécessaires.
