A. Distance of communication is greater then wi - fi

B. The term Li-Fi was coined by Harold Haas

C. Latest version of Li - Fi was released by Hedy Lamarr

D. Li - Fi cannot work in high data density environment

Choose the correct answer from the options given below:

The correct answer is A and B Only

Key Points

• Li-Fi:
  •  Li-Fi commonly stands for Light Fidelity.
  • It is a wireless technology that transmits high-speed data using visible light communication (VLC) as a medium of transmission.
  • It is capable of transmitting data at high speeds over visible light, ultraviolet, and infrared spectrums, and it can achieve communication over longer distances compared to traditional Wi-Fi in certain scenarios.
  • The technology 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.
  • It multiplies the speed and bandwidth of wifi, 3G, and 4G. It means it is faster than Wi-Fi.
  • Professor Harold Haas, a researcher at the University of Edinburgh, is widely credited with coining the term "Li-Fi" and pioneering the development of this technology. He introduced the concept of using visible light for wireless data communication and demonstrated its feasibility in various research projects.
  •  Li-Fi technology is designed to work efficiently in high data-density environments. In fact, one of the advantages of Li-Fi is its ability to handle high data rates and dense device connectivity. 

Additional Information

• Wi-Fi- 
  • Wi-Fi is a wireless networking technology that allows devices such as computers (laptops and desktops), mobile devices (smartphones and wearables), and other equipment (printers and video cameras) to interface with the Internet.
  • It allows these devices--and many more--to exchange information with one another, creating a network.
  • It uses radio waves to allow high-speed data transfer over short distances.
