With the development of smart cities and the era of big data, the era of Internet of Things has arrived. wireless communication will realize the interconnection of everything, and the reliable and secure transmission of data is the basis of the interconnection of everything. In most cases, people complete data transmission through short-distance communication technologies such as Bluetooth , WIFI, 4G, 5G, GPRS, etc. In order to meet different needs and increase the popularity of IoT services, a technology called narrowband Internet of Things (NB-IOT) was born.
narrowband Internet of Things is an emerging technology in the field of the Internet of Things, suitable for long-distance low-speed and low-frequency data transmission. The applications of IoT technology we currently see are basically narrowband Internet of Things. It supports low-power devices to connect data in wide area network , with fast transmission speed and good connection effect. Compared with mobile communication technology, narrowband Internet of Things has many advantages:
1, has a wide coverage area and strong coverage power, which is 100 times that of traditional mobile networks, and is suitable for the needs of large-scale coverage and deep coverage.
2. The number of connections is large, 50-100 times the number of other accesses, which can ensure large amounts of data access.
3. Low power consumption and high amplifier rate can increase the usage time of the device and reduce the problems caused by insufficient power.
4. Simplify RF hardware and protocols, no need to rebuild, the chip size is small and the module cost is low.
5. Transfer data, encrypted processing, safe and reliable.
Narrowband Internet of Things is closely related to our lives and is widely used in medical care, smart cities, smart homes, consumer electronics, smart agriculture, production and manufacturing, logistics industries and other fields. The following editor will give an example to let everyone better understand what narrowband Internet of Things is.
is an intelligent lighting system in smart cities. It adopts narrowband Internet of Things technology and can remotely control the lighting system. When people or vehicles pass by, they increase the brightness, and when there is no, they reduce the brightness, reducing the waste of power resources.
The second is a smart wearable device that can provide health advice to our body, monitor our sleep quality, etc.; it can also monitor the patient's vital signs, and warn when an emergency occurs.
The third is the vehicle positioning system. Shared bicycles can be seen everywhere in the city. Parking, loss, and power shortage are all problems that need to be solved. Narrowband Internet of Things technology can conduct real-time positioning and data exchange of bicycles and control them.
Fourth, environmental monitoring equipment can provide data support for urban construction, improve construction efficiency, and at the same time monitor water quality and improve the natural environment.
5 is a remote access control system, which uses narrowband Internet of Things technology for long-distance communication. The product's usage time and functions are very complete, which can reduce family property losses.
or above is a brief introduction to narrowband Internet of Things applications. In addition, there are many applications, such as remote meter reading, water level monitoring, fire alarm monitoring, intelligent anti-lossing, etc. The narrowband Internet of Things is permeating our lives, and more and more smart devices will be used in the future. Muwo Technology believes that the narrowband Internet of Things is opening up a market with huge prospects and will lead the Internet of Things market to prosperity.
