Abstract:
The chapter explores LiFi (Light Fidelity), a groundbreaking wireless communication technology that harnesses visible light for rapid data transmission, presenting a viable alternative to traditional radio frequency (RF) communication systems. Utilizing light-emitting diodes (LEDs) as data sources, LiFi simultaneously provides illumination and data transfer through imperceptible light. Originating in the early 2000s and gaining prominence with Professor Harald Haas’s 2011 TEDGlobal talk, LiFi has progressed from concept to a practical communication solution with advancements in data transfer speeds, reliability, and security. The technology’s advantages include increased data capacity, reduced latency, and heightened security, as visible light signals are confined within physical boundaries, mitigating unauthorized access risks. Applications of LiFi extend across various sectors, including healthcare, finance, and government. The chapter delves into the fundamentals, applications, standards, ongoing research, challenges, and the future outlook of LiFi, shedding light on its potential to shape the future of data transmission.
