Introduction
Narrowband IoT, also known as NB-IoT or Narrowband Internet of Things, is a revolutionary radio technology specifically designed for the Internet of Things (IoT). It operates over existing mobile networks, offering superior indoor coverage, extended battery life, and a wide variety of compatible devices, all at a relatively low cost.
What is NB-IoT Technology
NB-IoT is a standards-based low power wide area (LPWA) technology developed to enable a wide range of new IoT devices and services. It uses a spectrum in the lower MHz range with a bandwidth of 200kHz, offering more channels than LTE or Wi-Fi. This NB-IoT network architecture benefits from all mobile networks' security and privacy features, including user identity confidentiality, entity authentication, confidentiality, data integrity, and mobile equipment identification.
NB-IoT is best suited for stationary devices that send small amounts of data, a few MB per month at most. Thanks to its longer wavelength, it can operate where other technologies struggle to get a signal. Let's delve into the advantages and potential challenges of Narrowband IoT.
Advantages of NB-IoT
Superior Indoor Coverage
NB-IoT devices employ a new physical layer with signals and channels designed to extend coverage in rural areas and deep indoors. By design, NB-IoT adds up to an additional 20 dB of transmission power, allowing signals to travel further and penetrate structures more effectively.
Cost-Effective
NB-IoT modules are simpler and less expensive to manufacture compared to 4G LTE modules, making them more affordable. Additionally, the low data usage of NB-IoT devices results in lower cellular data costs.
Extended Battery Life
Unlike regular 4G LTE networks, which were designed for phones transferring large amounts of data, NB-IoT is optimized for devices that use less data, thereby extending battery life. This can significantly reduce the total cost of ownership for IoT devices.
