NB-IoT (Narrowband Internet of Things) is a Low Power Wide Area Network (LPWAN) technology designed specifically for Internet of Things (IoT) applications. It enables cost-efficient connectivity for a wide range of devices, including sensors, meters, cameras, wearables, and more. NB-IoT operates in licensed spectrum and supports both indoor and outdoor coverage, making it suitable for a variety of deployment scenarios.
NB-IoT operates on different frequency bands across the world, depending on the regulatory requirements of each country and region. The following are some of the common frequency bands used for NB-IoT:
1. Band 1 (2100 MHz) – This band is used in Europe, Middle East, Africa, and some countries in Asia. It provides good indoor penetration and coverage.
2. Band 2 (1900 MHz) – This band is used in Latin America and some countries in Asia. It provides good coverage and capacity.
3. Band 3 (1800 MHz) – This band is mainly used in Asia and Africa. It provides good coverage and capacity.
4. Band 5 (850 MHz) – This band is used in North America and some countries in Asia. It provides good coverage and penetration.
5. Band 8 (900 MHz) – This band is used in Europe, Asia, and Africa. It provides good coverage and penetration.
6. Band 12 (700 MHz) – This band is used in North America and provides good coverage and penetration.
7. Band 13 (700 MHz) – This band is used in North America and provides good coverage and penetration.
8. Band 20 (800 MHz) – This band is mainly used in Europe and provides good coverage and penetration.
9. Band 28 (700 MHz) – This band is used in some countries in Asia and provides good coverage and penetration.
10. Band 66 (1700/2100 MHz) – This band is used in North America and provides good capacity and coverage.
It is important to note that the availability of these frequency bands may vary depending on the country and region where the NB-IoT deployment is planned. In addition, some frequency bands may be reserved for other applications or services, which may limit the availability of the spectrum for NB-IoT.
In conclusion, the frequency bands used for NB-IoT depend on the regulatory requirements of each country and region. The technology operates in licensed spectrum and supports both indoor and outdoor coverage, making it suitable for a variety of deployment scenarios. Understanding the available frequency bands and their characteristics is crucial for successful implementation of NB-IoT applications.。
