Title (EN) AUDIO COMMUNICATION TOKENS
(FR) JETONS DE COMMUNICATION AUDIO
Abstract:
(EN) A first device listens for a communication token across an audio bandwidth covering a transmit frequency one or more audio frequency broadcasting device. The first device receives at least one token broadcast from the one or more broadcasting devices. The first device demodulates and decodes each received token. One or more computing devices validates each decoded token. The first device determines, based on the validating, a broadcasting device of the broadcasting devices with which to establish a communications channel. The one or more computing devices generates a response token based on the token received from the determined device. The first device broadcasts the generated response token in a response band of the determined device. The determined device demodulates decodes, and validates the token broadcast from the first device. Upon determining the token broadcast from the first device valid, the first device and the determined device establish a wireless communication channel.
(FR) L'invention concerne un premier dispositif écoutant un jeton de communication sur une bande passante audio couvrant une fréquence de transmission d'au moins un dispositif de diffusion de fréquence audio. Le premier dispositif reçoit au moins un jeton diffusé à partir dudit dispositif de diffusion. Le premier dispositif démodule et décode chaque jeton reçu. Au moins un dispositif informatique valide chaque jeton décodé. Le premier dispositif détermine, en fonction de la validation, un dispositif de diffusion des dispositifs de diffusion permettant d'établir un canal de communication. Ledit dispositif informatique produit un jeton de réponse en fonction du jeton reçu à partir du dispositif déterminé. Le premier dispositif diffuse le jeton de réponse généré dans une bande de réponse du dispositif déterminé. Le dispositif déterminé démodule, décode et valide la diffusion de jeton à partir du premier dispositif. Lors de la détermination de la validité du jeton diffusé à partir du premier dispositif, le premier dispositif et le dispositif déterminé établissent un canal de communication sans fil.
