Write a short note on Light Fidelity (Lifi) Technology

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
