Shulou(Shulou.com)06/03 Report--

NB-IoT is a new cellular technology developed by 3GPP Standardization Organization, which is a kind of low power wide area (LPWA) Internet of things connection. It is mainly used to connect terminals with limited bandwidth resources, allowing terminals to collect and exchange data with less resources than GRPS, 3G, LTE and other technologies.

NB-IoT developed rapidly from 2017 to 2018, and many operators around the world have achieved commercial deployment one after another. The low cost, low power consumption and wide coverage of NB-IoT enable users to implement new scenarios and new applications that can not be supported by traditional cellular networks.

The advantage of NB-IOT technology is that the new cellular technology designed by the Internet of things and M2M covers the large area power efficiency of the distance unit 10km, the low cost of a battery working in the field for 10 years, the cost of NB-IoT module is about 20 yuan, and there is a decreasing trend year by year.

Starting in 2017, EMQ X began to work with a top operator to develop the Internet of things platform project, and released a new Internet of things Application enabling platform (AEP) supporting NB-IoT technology in 2018. The platform allows the NB-IoT terminals of customers in the industry to access directly through the NB-IoT network of operators, and quickly build Internet of things applications through the open capabilities of the platform.

With the help of device access, message routing, data storage, and device control services provided by the AEP platform, the development process of applications can be greatly simplified. Most applications can be completed by dragging and dropping platform components and defining templates. Customers can also have fully functional self-developed IoT applications through the rich API interface of the platform and a small amount of coding work. The applications developed by customers can be run directly on the platform, which can save a lot of operating costs.

In this project, EMQ X Internet of things message middleware, as the core component of the platform, is used to access all kinds of Internet of things devices of operators nationwide (mainly NB-IoT, including all networks such as 3GLI 4G pone, etc.), aggregates massive device messages to the platform data layer through efficient protocol parsing and message routing ability, and also provides reliable reverse control channel for back-end device management and application module.

The innovative distributed cluster scheme of EMQ X can realize the automatic addition of new nodes and the automatic deletion of faulty nodes, which effectively ensures the automatic expansion and long-term stable operation of the access capacity of AEP platform, and improves the reliability of operators' customer services.

EMQ X's massive device access, tens of millions of high concurrency, Internet of things full protocol stack, and millisecond low latency capabilities helped the carrier-grade AEP platform of the Internet of things to be built within months, effectively supporting the landing and commercial operation of the operator's NB-IoT and even the entire IoT platform strategy.
