Li-fi, a communication technology harnessing visible light for data transmission, has a potential to surpass Wi-Fi’s speed by more than 100 times and boasts a high bandwidth, facilitating the simultaneous transmission of copious information. Notably, Li-fi ensures robust security by exclusively transmitting data to areas illuminated by light.

Most important, it capitalizes on existing indoor lighting infrastructure, such as LEDs, eliminating the need for separate installations. However, implementing visible light communication (VLC) in practical lighting systems poses an issue of diminished stability and accuracy in data transmission.
