Visible Light Communication

This self-paced training introduces the rapidly growing field of Visible Light Communication (VLC), a next-generation wireless technology that uses the visible spectrum (400–700 nm) for data transmission. Learners will explore the fundamental concepts, system components, modulation techniques, and applications of VLC—from indoor internet access to vehicular communication and underwater systems.
