ABSTRACT

Visible Light Communication (VLC), with its advantages of 400 THz unlicensed spectrum, electromagnetic interference immunity, high security, and integrated lighting communication, has emerged as a crucial complementary technology for 5G/6G indoor high-speed access. To address 5G millimeter-wave coverage blind spots and 6G's ubiquitous connectivity and ultra-high-speed demands, this study systematically analyzes key technologies including high-speed modems, MIMO-VLC, heterogeneous network coordination, and light source optimization. A prototype system combining OFDM modulation and GaN Micro-LED is designed and implemented. Experimental results demonstrate peak rates of 10 Gbps, 99.99% link reliability, and seamless 5G NR handover in 10 m indoor line-of-sight scenarios. These findings provide technical solutions and practical references for 6G indoor ubiquitous high-speed access.
