Title (EN) BACKSCATTERING AMBIENT ISM BAND SIGNALS
(FR) RÉTRODIFFUSION DE SIGNAUX DE BANDE ISM AMBIANTS
Abstract:
(EN) A backscatter tag device includes, in part, a receiver configured to receive a packet conforming to a communication protocol defining a multitude of codewords, a codeword translator configured to translate at least a first subset of the multitude of codewords disposed in the packet to a second multitude of codewords defined by the protocol in response to a data the backscatter tag is invoked to transmit, and a transmitter configured to transmit the packet supplied by the codeword translator at a frequency different than the first frequency at which the packer is received. The communication protocol may optionally be the 802.11 g/n, ZigBee or the Bluetooth communication protocol.
(FR) L'invention concerne un dispositif d'étiquette de rétrodiffusion qui comprend, en partie, un récepteur conçu pour recevoir un paquet conforme à un protocole de communication définissant une multitude de mots codés, un traducteur de mot codé conçu pour traduire au moins un premier sous-ensemble de la pluralité de mots codés placés dans le paquet en une seconde multitude de mots codés définis par le protocole en réponse à une donnée que l'étiquette de rétrodiffusion est appelée à transmettre, et un émetteur conçu pour transmettre le paquet fourni par le traducteur de mot codé à une fréquence différente de la première fréquence à laquelle le paquet est reçu. Le protocole de communication peut, facultativement, être le protocole 802.11 g/n, ZigBee ou Bluetooth.
