Q. With reference to Narrow band-Internet of Things (NB-IoT), sometimes seen in the news, consider the following statements:
Which of the statements given above is/are correct?
Q. With reference to Narrow band-Internet of Things (NB-IoT), sometimes seen in the news, consider the following statements:
Which of the statements given above is/are correct?
The correct option is A 1 and 2 only
Explanation:
Statement 1 is correct: NB-IoT is a wireless communication standard for the Internet of Things (IoT) belonging to the category of low-power wide-area networks (LPWAN). It enables devices that require small amounts of data, low bandwidth, and long battery life.
Statement 2 is correct: NB-IoT can co-exist with 2G, 3G, and 4G mobile networks. It doesn’t operate in the licensed LTE construct, Instead, it works in one of three ways:
- It can work independently
- In the unused 200-kHz bands that have previously been used for GSM (Global System for Mobile Communications).
- On Long-Term Evolution (LTE) based stations allocating a resource block to NB-IoT operations or in their guard bands.
Statement 3 is incorrect: Recently, BSNL, in partnership with Skylotech India, announced a breakthrough in satellite-based NB-IoT (Narrow Band-Internet of Things), in pursuance of the vision of a truly Digital India starting with fishermen, farmers, construction, mining, and logistics enterprises. With this solution, India will now have access to a ubiquitous fabric of connectivity for millions of yet unconnected machines, sensors, and industrial IoT devices.
