METHOD OF WIRELESS ACCESS TO THE INTERNET THROUGH VISIBLE AND INFRARED LIGHT AND A DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2019 - IPC G09G5/36 H04B10/116 

FIELD: wireless communication equipment.

SUBSTANCE: invention relates to communication. Device comprises a router which converts data from the Internet and sends white LEDs to the matrix. From the white LED matrix, the modulated optical signal propagates in the free space and reaches the visible light photodetector of the USB module, is demodulated in the USB module and transmitted to the end user device. Data from the end user device are transmitted to a USB module, where it is converted and transmitted to an infrared emitter. Modulated radiation of the infrared range passes through free space and is transmitted to the infrared photodetector module, and the electric signal from the infrared photodetector module is transmitted to the router, where it is demodulated and sent via TCP/IP to the global network.

EFFECT: end-user device access to a high-speed broadband Internet by a wireless communication system based on modulated visible and infrared light.
