NB-IoT technology is a low-power wide-area IoT technology based on the 3GPP standard, and is now widely used in the field of IoT.NB-IoT technology adopts a narrow-band modulation method, which can realize transmission across buildings, penetrate depths and other complex environments, and has a wide range of application scenarios. So how big is the bandwidth of NB-IoT technology?
The bandwidth of NB-IoT technology is usually between 180kHz and 1.4MHz. Compared to traditional 4G networks, its bandwidth is narrower. However, the advantage of NB-IoT technology is that the transmission distance and penetration depth are higher, which can meet many requirements of IoT devices such as low power consumption, long life and stability. In addition, NB-IoT technology excels in reachability and can provide efficient services in environments where a large number of devices are densely populated.
NB-IoT technology has a wide range of applications, including smart home, smart logistics, smart city, smart healthcare, industry 4.0 and other fields. Taking smart city as an example, NB-IoT technology can realize intelligent management of the city by collecting data from urban public **** facilities such as streetlights, parking lots and traffic signals. In the field of smart healthcare, NB-IoT technology can realize telemedicine and the allocation and management of medical resources by collecting patient data. In the field of Industry 4.0, NB-IoT technology can realize remote maintenance of equipment and more efficient equipment utilization by collecting data on equipment operation.
In short, despite the narrow bandwidth of NB-IoT technology, its application in the field of IoT is very promising, and it realizes a variety of characteristics of IoT devices, such as long-life, low-power, stability, etc., and more application scenarios will emerge in the future.
