This year is the first year of NB-IoT large-scale commercial, Changzhou Mobile firstly lay out NB-IoT network in the local operators, assisting all things to a new level.

According to the introduction from Changzhou Mobile staff, NB-IoT (Narrow Band Internet of Things, NB-IoT) is a cellular-based narrowband networking technology that has four major advantages over existing networks: first, covering a wide range, in the same frequency band, NB-IoT coverage area will be expanded 100 times, can effectively improve the indoor coverage; second, with the ability to support massive connectivity, a sector of NB-IoT can support 100,000 connections, and support low latency sensitivity, low power consumption and optimized network architecture; third, with low power consumption, standby tim of NB-IoT terminal module e can be up to 10 years; fourth, with low cost of the module, the company expects a single successive module not more than $ 5.

Changzhou Mobile staff also introduced that NB-IoT this emerging technology having broad prospects for the application in the smart factory, intelligent transportation, intelligent parking and other aspects of social life, and a specific description of the blueprint of the NB-IoT network based on "all things interconnection ".

For example, in the construction of the smart factory, you can use NB-IoT to collect all the data of each production line to OneNet cloud platform, using back-end large data analysis technology to the whole process of manufacturing, thereby enhancing production efficiency and improving the level of quality control. In the construction of intelligent traffic, you can use NB-IoT technology to collect the passing time, traffic flow and other information of cross-traffic vehicles, according to this optimizing the traffic light time and reducing congestion; according to the night traffic control light brightness, opening and closing time for intelligent street management using NB-IoT, to achieve energy efficiency goals. In the intelligent parking, it can also network with social scattered parking lot information through the NB-IoT, to optimize the efficiency of the parking lot through intelligent tips, booking parking and other functions.

At present, Changzhou Mobile has completed NB-IoT pilot deployment in Xibei innovation park, Wujin economic development zone, the bell tower development zone, covering science and technology park, residential area, industrial park and other scenes, to meet the intelligent lights, smart meters, Intelligent factories and other business testing needs.

Changzhou mobile staff revealed that they will continue to carry out large-scale deployment during the year, and gradually improve the region's NB-IoT network, and combining with the actual needs of the industry to open up more application scenarios for the general public to bring "smart life" new Experience. " if necessary , enterprises and institutions can contact our company priority network, which can be opened in this month." (Feng Fei)
