With reference to ‘Li-Fi’, recently in the news, which of the following statements is/are correct?
a) It uses light as the medium for high-speed data transmission.
b) It is a wireless technology and is several times faster than ‘Wi-Fi’.
The correct answer is Both 1 and 2.
Li-Fi
It is a wireless technology that transmits high-speed data using visible light communication (VLC) as a medium of transmission. Hence statement 1 is correct.
It is loosely expanded to Light-Fidelity.
By using precisely controlled light modulation, data can be transmitted using regular, visible light.
It will also allow connectivity in environments that do not currently readily support Wi-Fi, such as aircraft cabins, hospitals and hazardous environments.
This technology is 100 times faster than the average Wi-Fi speeds. Hence statement 2 is correct.
It can transmit up to 100 Gbps.
