ELECTRONIC DEVICE ASSOCIATED WITH A PHOTOVOLTAIC MODULE FOR OPTIMIZING THE FLOW OF A VLC TYPE BIDIRECTIONAL TRANSMISSION

摘要

A bidirectional wireless communication device based on the use of light comprising at least: (a) one or more transmission modules (10), each transmission module (10) being composed of: - a light source (9) powered by a control means (6) and emitting modulated light (1) in amplitude and / or in phase; - a control means (6) which generates an electrical signal from the digital / analog conversion of the source data (2) to be transmitted; (b) a receiving module (20) composed of: - a photodetector (11) illuminated by said modulated light (1) and generating a modulated electrical signal (14,15) in response to said modulated light (1); - A processing module (12) of the signal generated by said photodetector (11) adapted to communicate with the control means (6) via the return channel (17). Said wireless communication device is characterized in that the receiving module (20) further comprises an electronic means (13) located between the photodetector (11) and the signal processing module (12) and able to adapt the impedance of the photodetector (11) to maximize the data rate transmitted (18).
