NB-IoT has become one of the most promising IoT technologies. It can be deployed directly on GSM, 4G or LTE networks and can be deployed to 5G networks in the future. Therefore, the NB-IoT network will occupy the global carrier-grade Internet of Things. Part of the application. It is expected that the number of low-speed WAN connections will account for 60% of the total number of IoT connections. Considering the specific application, NB-IoT technology combined with its real-time data time is mainly used in low-power wide-area IoT communication. Insensitive features, intelligent reading, soil environment monitoring, object tracking and other areas where strict environmental and energy requirements are required will be very suitable. In addition, the construction of smart cities represented by parking lots, street lights, trash cans, fire hydrants, etc. will also become typical application scenarios for NB-IoT.
NB-IoT is applied to smart meters, which can effectively solve traditional wiring, equipment cost, environmental requirements, energy consumption and other issues, making the meter stable and reliable. It shares with existing 4G base stations and does not consume additional network and data bandwidth to ensure stable operation of legacy services and integration with emerging IoT applications. In the application of smart meter reading, currently using GPRS network to send data, a base station can only load more than 300 water meters at the same time. After using NB-IoT technology, one base station can carry 50,000 water meters. Transfer data at the same time.
