LiFi Technology
What is LiFi? LiFi, also known as "Light Fidelity" is a wireless optical networking technology, which uses light emitting diodes (LEDs) to transmit data. In 2011, professor Harald Haas made a LiFi demonstration at the TED (Technology, Entertainment, Design) Global Talk on Visible Light Communication (VLC).VLC involves light as medium to deliver high-speed communication in a manner similar to Wi-Fi and agrees with the IEEE standard IEEE 802.15.7. The IEEE 802.15.7 is a high-speed, bidirectional and completely organized wireless communication technology-based standard similar to Wi-Fi's IEEE 802.11. How does LiFi work? LiFi is a high speed, bidirectional, and completely organized wireless communication of data using light. LiFi comprises of several lightbulbs that structure a wireless organization. At the point when an electrical current is applied to a LED light bulb a stream of light (photons) is emitted from the bulb. LED bulbs are semiconductor gadgets, and that means
