Abstract

The growing number of wireless devices and increasing traffic density place a significant strain on the radio-frequency spectrum. Traditional communication channels – such as Wi-Fi and Bluetooth – face bandwidth limitations and are susceptible to interference. Against this backdrop, Visible Light Communication (VLC) technology emerges as a compelling alternative: it leverages LED lighting infrastructure for data transmission, without competing for radio-frequency resources. VLC technology provides additional, high-capacity communication channels and creates new opportunities for establishing secure, high-speed networks within indoor environments and for various specialized applications. VLC is a non-fiber-optic data transmission technology based on the use of visible light. A key motivation for this technology is that light can simultaneously serve the purposes of illumination, communication, and/or positioning. Consequently, this multifunctionality eliminates the need for an additional power source for data transmission or location tracking. The transition from legacy light sources to light-emitting diodes (LEDs) can be integrated with VLC technology. This article examines the operating principles of VLC, technical approaches, advantages, limitations, current challenges, and potential solutions. It also presents results from computer simulations and mathematical models of VLC systems .

Keywords: VLC, modulation, optical wireless communication, On-Off Keying (OOK), Pulse Position Modulation (PPM)
