NB-IoT - The Fastest Growing Wireless Technology

We'll soon have billions of gadgets online, necessitating wireless networks capable of handling them. This is a significant load on the network, and it also demands a huge amount of energy. Is NB-IoT (narrow-band Internet of Things) the answer?

What is narrow-band?

Narrow-band Internet of Things (NB-IoT) is an LPWAN (Low Power Wide Area Network) technology. LPWAN connects devices that require low bandwidth, tiny data volumes, and long battery life. It has better indoor and outdoor coverage, making it ideal for a wide range of IoT applications.

A narrow band machine sensor network uses 3gpp radio waves to cover a large area. It penetrates thick concrete walls and even reaches deep into the ground to reach remote regions of a building.

Only little data packets are transmitted once a day, week, or month by the sensors. They use far less energy. This means we won't have to replace the batteries for a long time.

Why Narrowband?

The broadband environment is used for mobile communication. The majority of these channels' expensive bandwidth goes unused. Narrow-band, on the other hand, has much less bandwidth than broadband. The reduced bandwidth has allowed for a low-power signal to be transmitted over a great distance. It also has a strong resistance to interference.

The internet of things (IoT) is a network of interconnected computing devices with unique identifiers that can transfer and compute data without requiring human-to-human or human-to-computer contact.

Let’s see an example. A smart energy meter is connected as an end node to a network. Through the NB IoT network, the energy meter may send energy ratings and other data to a server. Without any human-to-human or human-to-computer interaction, the server can analyze that data and take actions, such as creating an invoice or calling for maintenance.

NB-IoT Applications

NB-IoT applications can be used in a range of service categories, including:

  • Smart metering (electricity, gas, and water)

  • Services for facility management

  • Fire and intruder alarms for residential and commercial properties.

  • Health-monitoring devices that are connected to the internet.

  • Person, animal, or object tracking

  • Street lamps and garbage cans in smart city infrastructure.

  • Welding machines and air compressors (connected industrial appliances)

The Benefits of NB IoT

NB IoT connects devices across a wide region, allowing for long-range communication at a lower bit rate, lower cost, and higher energy efficiency. It just requires a tiny amount of data transfer and low bandwidth, resulting in improved battery life penetration power and device density.

Business Benefits:

1. Power Efficiency

When IoT technologies are not in use, they are designed to save energy. They do, however, consume energy when the modem is active and processing signals. IoT devices consume less energy and eliminate the need for billions of batteries to be replaced regularly.

2. Cost-cutting

NB-IoT uses less energy. Analog-to-digital (A/D) and digital-to-analog (D/A) conversion, buffering, and channel estimate are all simplified with a 200 kHz NB-IoT frontend and digitizer. Power conservation is a cost-cutting measure. Also, NB-IoT chips are easier to make and thus less expensive.

3. Dependability

Users will benefit from the implementation of NB-IoT on a licensed spectrum. For controlled Quality of Service (QoS), a guaranteed resource allocation is also necessary.

4. Wider Deployment and Global reach

NB-IoT could assist IoT entrepreneurs in finding cost-effective entry points into new markets around the world. Larger GSM deployments can take advantage of unused bands for NB-IoT deployments.

Potential Roadblocks to NB IoT Implementation

With most carriers transitioning to LTE support, deployment could be a challenge. There may be higher initial expenditures to develop operating software if NB-IoT is deployed in a sideband. Furthermore, in circumstances where there is little current GSM spectrum, modem frontends and antennas may become more sophisticated.


There are numerous data transport technologies available today. Each has its own set of advantages and disadvantages. NB-IoT (Narrow-band Internet of Things) has been the most talked-about technology in recent years, and it will be widely used in the coming years in a variety of industries. Many are hoping to make this the best low-power with so much underused 200-kHz GSM spectrum. Cellular IoT will have an even brighter future with the advent of 5G. NB-IoT employs a spectrum that is free of interference from other devices, ensuring more dependable data transmission. Because of its capacity to cover a wide range of devices, NB-IoT appears to be the ideal option. Its simpler infrastructure allows for faster and easier adoption.
