About Light Fidelity (Lifi) Technology
- LiFi is a wireless optical networking technology, which uses light emitting diodes (LEDs) to transmit data.
- It makes a LED light bulb emit pulses of light that are undetectable to the human eye and within those emitted pulses, data can travel to and from receivers.
- LiFi is not strictly a line-of-sight technology i.e. data rate is not dependent on the line of sight but on the signal quality at the device
Advantages of LiFi systems:
- Provide ultra-fast data connections, Useful in urban areas where radio spectra are congested and also in rural areas wherein Fiber Optic Cables or networks are not reachable etc
- Unlike Wi-Fi that uses radio waves for data transmission, LiFi uses light
