Unlike WiFi, which relies on radio frequency (RF) waves to transmit data, its counterpart LiFi simply needs light. LiFi is a wireless optical networking technology that transmits data using light-emitting diodes (LEDs). LED lightbulbs are very popular in energy-conscious homes, offices, and other facilities.
There are numerous benefits to LiFi over WiFi like being significantly faster and possessing 10,000 times the frequency spectrum of radio. LiFi is more secure since data can’t be intercepted without a clear line of light. LiFi also eliminates and is unaffected by neighboring networking and radio interference. Since it doesn’t create interference in sensitive electronics, LiFi is more ideal to use in work environments like hospitals and airplanes.
This begs the question how does this technology work, and what does the process entail in transmitting data via LEDs? The video below offers a step-by-step breakdown that describes the path transmitted data takes using this unfamiliar but innovative method.
