Abstract

Un mode de réalisation de la présente invention concerne un procédé de communication sans fil Li-Fi. Le procédé est utilisé sur un dispositif de service de point d'accès sans fil accédant à un réseau Ethernet. Le procédé comprend les étapes suivantes : un dispositif de service de point d'accès sans fil attribue un canal dédié à un dispositif terminal correspondant à un numéro d'identificateur reçu ; le dispositif de service de point d'accès sans fil envoie des données de réinitialisation de canal au dispositif terminal par l'intermédiaire d'un canal public, et établit une relation d'interaction de données avec le dispositif terminal ; et le dispositif de service de point d'accès sans fil envoie, par l'intermédiaire du canal dédié, des données d'interaction de canal au dispositif terminal à l'aide de la relation d'interaction de données. Des modes de réalisation de la présente invention concernent également un dispositif et un système de communication sans fil Li-Fi, et un support d'informations.
