NB-IoT – A Narrowband Wireless Technology for Low-Power IoT Applications

Share This Post

Narrowband IoT (NB-IoT) is a low-power wireless technology that enables the deployment of IoT applications on a large scale. It is designed to operate in a licensed spectrum, which provides a high level of security and reliability. NB-IoT is well-suited for low-power applications that require infrequent data transmission and can operate for long periods on a single battery.

Overview of NB-IoT:

One of the primary advantages of NB-IoT is its low power consumption. It uses a low-power mode that reduces power consumption significantly, enabling devices to operate for up to 10 years on a single battery. This makes NB-IoT an ideal choice for IoT applications that are difficult to access and require long battery life.

Another significant advantage of NB-IoT is its reliability. It is designed to operate in challenging environments, and it can penetrate deep indoors, underground, and in other difficult-to-reach locations. Additionally, NB-IoT supports secure communication, making it suitable for applications that require a high level of security.

NB-IoT offers a high degree of scalability, enabling the deployment of IoT applications on a large scale. It can support a massive number of devices, up to millions per cell, and provides a seamless connection to the internet, making it an ideal choice for smart cities, smart homes, and industrial IoT applications.

Overall, NB-IoT is a powerful wireless technology that enables low-power IoT applications on a large scale. Its low power consumption, reliability, and scalability make it an ideal choice for various applications, from smart homes to industrial automation.

Key Technical Parameters:

  • Standard: 3GPP Release 13/14
  • Frequency band: 800 MHz, 900 MHz, and 1.9 GHz
  • Range: up to 10 km in rural areas and up to 1 km in urban areas
