This paper presents the design and analysis of an indoor Visible Light Communication (VLC) system utilizing LED modulation to achieve high-speed data transmission up to 10 Gbps. As wireless networks face increasing RF spectrum congestion, VLC offers a viable alternative by leveraging the visible light spec- trum through existing lighting infrastructure. This enables simultaneous illumination and data transmission, creating wireless hotspots ideal for RF-restricted environments such as hospitals, aircraft, and underwater systems. VLC provides notable advantages over traditional RF technologies, including improved energy efficiency, enhanced security (as visible light is confined to physical spaces), and reduced electromagnetic interference. The study investigates key VLC principles, including modulation techniques like OOK, PPM, and OFDM, along with system architecture, photodetectors, and challenges such as line-of-sight dependency and ambient light interference. Through simulations and experimental validation, the paper demonstrates VLC’s potential to support next-generation networks. It highlights applications in IoT, smart homes, and intelligent transportation, showcasing VLC as a scalable, eco-friendly, and high-capacity communication solution for the future.

摘要

This paper presents the design and analysis of an indoor Visible Light Communication (VLC) system utilizing LED modulation to achieve high-speed data transmission up to 10 Gbps. As wireless networks face increasing RF spectrum congestion, VLC offers a viable alternative by leveraging the visible light spec- trum through existing lighting infrastructure. This enables simultaneous illumination and data transmission, creating wireless hotspots ideal for RF-restricted environments such as hospitals, aircraft, and underwater systems. VLC provides notable advantages over traditional RF technologies, including improved energy efficiency, enhanced security (as visible light is confined to physical spaces), and reduced electromagnetic interference. The study investigates key VLC principles, including modulation techniques like OOK, PPM, and OFDM, along with system architecture, photodetectors, and challenges such as line-of-sight dependency and ambient light interference. Through simulations and experimental validation, the paper demonstrates VLC’s potential to support next-generation networks.
