Question

Consider the following statements about 'LiFi'.
$1$. It is an internet service that operates in the visible range of the spectrum.
$2$. It is uses LASER for the transmission of data through the optical fiber cable.
Which of the given statement(s) is/are correct?

• A. $1$ only
• B. $2$ only
• C. Both $1$ and $2$
• D. Neither $1$ nor $2$

Answer 1

Answer: (A)

$1$ only

LiFi is a wireless optical networking technology that uses light-emitting diodes (LEDs) for data transmission. The visible light spectrum is plentiful, unlicensed and free to use. Li-Fi can achieve about 1000 times the data density of Wi-Fi because of its use of visible light. It requires fewer components than radio technology and LED illumination is already efficient and the data transmission requires negligible additional power.Therefore option A is correct.
