A communication device designed for an interior compartment, for example of a motor vehicle. The device includes a radiofrequency communication module and an interface module which is operationally coupled to the radiofrequency communication module in order to receive a digital signal generated by the radiofrequency communication module, and to modulate an electric power supply signal for at least one lamp, according to the digital signal, in order to generate a modulation of light emitted by the lamp according to the digital signal received from the radiofrequency communication module.

Communication device designed for interior compartments, particularly of motor vehicles

A terminal is described, along with a method for data processing carried out by the terminal, for communication via a plurality of interfaces of the terminal. The terminal can include a first interface for communication via a radiofrequency link, and a second interface for communication via a short-range link, where the second interface can be polluted by the radiofrequency link used by the first interface. The terminal can be configured to activate the first interface, deactivate the first interface and initiate a time-out during which the terminal can activate a third interface for communication via an optical link, and then activate the second interface.

Activation of communication interfaces of a terminal

A lighting device includes at least one first fixed light source dedicated to lighting, at least one second light source dedicated to data transmission by light modulation, and first and second refractor optical devices positioned respectively with respect to the first and second light sources, so as to sense the light emitted by said sources and form respectively first and second distinct light beams, said second light beam delimiting a data transmission zone. The lighting device also includes a variator of the brightness and/or the color of the first light beam, which is accentuates or decreases the visibility of the data transmission zone delimited by said second light beam, according to the availability or the unavailability respectively of the data transmission service in the data transmission zone.

Device for lighting and optical communication combined with viewing of the communication field
