Narrow Band-Internet of Things (NB-IoT)


From UPSC perspective, the following things are important :

Prelims level: IoT , AI

Mains level: Internet based applications

In a first, BSNL launches world’s largest NB-IoT to provide connectivity for millions of unconnected machines, sensors and industrial IoT devices across the country.

What is NB-IoT?

  • NB-IoT is a Low Power Wide Area (LPWA) technology that works virtually anywhere.
  • It will connect many more devices to the Internet of Things and make many new applications a reality.
  • It is optimized for applications that need to communicate small amounts of data over long periods of time.
  • Since it operates in licensed spectrum, it is secure and reliable providing guaranteed quality of service.
  • It connects devices more simply and efficiently on already established mobile networks and handles small amounts of fairly infrequent 2‑way data, securely and reliably.

And the best is, it provides-

  • very low power consumption
  • excellent extended range in buildings and underground
  • easy deployment into the existing cellular network architecture
  • network security & reliability
  • lower component cost

Back2Basics: Internet of Things (IoT)

  • The IoT describes the network of physical objects—“things”—that are embedded with sensors, software, and other technologies for the purpose of connecting and exchanging data with other devices and systems over the Internet.
  • The definition of the IoT has evolved due to the convergence of multiple technologies, real-time analytics, AI, sensors, and embedded systems.
  • In the consumer market, IoT technology is most synonymous with products pertaining to the concept of the “smart home”, including devices and appliances.
  • It supports one or more common ecosystems and can be controlled via devices associated with that ecosystem, such as smartphones and smart speakers e.g. Alexa.

Remember this PYQ?

When the alarm of your smartphone rings in the morning, you wake up and tap it to stop the alarm which causes your geyser to be switched on automatically. The smart mirror in your bathroom shows the day’s weather and also indicates the level of water in your overhead tank. After you take some groceries from your refrigerator for making breakfast, it recognises the shortage of stock in it and places an order for the supply of fresh grocery items. When You step out of your house and lock the door, all lights, fans, geysers and AC machines get switched off automatically. On your way to office, your car warns you about traffic congestion ahead and suggests an alternative route, and if you are late for a meeting, it sends a message to your office accordingly.

In the context of emerging communication technologies, which one of the following terms best applies to the above scenario?

(a) Border Gateway Protocol

(b) Internet of Things

(c) Internet Protocol

(d) Virtual Private Network
