Q. With reference to ‘LiFi’, recently in the news, which of the following statements is/are correct? :
1. It uses light as the medium for high-speed data transmission.
2. It is a wireless technology and is several times faster than ‘WiFi’.
Select the correct answer using the code given below.
Answer: C
Notes:
Explanation: Using light to deliver wireless internet will also allow connectivity in environments that do not currently readily support Wi-Fi, such as aircraft cabins, hospitals and hazardous environments. Light is already used for data transmission in fibre-optic cables and for point to point links, but Li-Fi is a special and novel combination of technologies that allow it to be universally adopted for mobile ultra high speed internet communications. Using the visible light spectrum, Li-Fi technology can transmit data and unlock capacity which is 10,000 times greater than that available within the radio spectrum.
