What is the Internet of Things (NB-IoT)?

Refers to the narrowband-Internet of Things technology. Nb-IOT focuses on the low-power wide-area (LPWA) Internet of Things market, which is a new technology and can be widely used around the world. China Telecom's NB-IoT network is based on the 800MHz low-frequency golden frequency band, and has built the world's largest NB-IoT network. Include 10649,14 14 10 1, and support basic communication services such as short messages and wireless data.

Second, product capacity.

Data service: that ability to support data access service.

Short message service: Support SGS short message communication capability.

NB gateway service: China Telecom provides NB gateway to realize seamless connection with NB-IoT network, meet the rapid access of a large number of devices with high concurrency, and realize the functions of resource subscription, storage, forwarding, command issuance and so on; NB gateway enriches API interfaces to help users quickly realize the development and opening of platform-related capabilities.

Third, product features:

Large connections: Each base station area can support 654.38+ million connections. Compared with the existing wireless technology, NB-IoT can increase access times by 50 ~ 654.38+000 times.

Wide coverage: Compared with the traditional GSM network, the coverage area provided by a base station is 10 times that of an ordinary base station, covering underground and inside buildings that are difficult to be covered by traditional networks.

Low power consumption: save power by reducing unnecessary signaling and not accepting paging information in PSM state. Ultra-low power consumption, the service life of ordinary batteries exceeds 10 years.

Easy to use: similar to the standard IOT card in appearance, size and other forms, compatible with the usage of the original IOT card, providing plug-ins, patches and eSIM usage.

Billing Jane: It provides annual billing mode, which is easy to move and supports various billing cycles including 10 long-term billing.

Low cost: mature industrial chain and low chip cost.

Fourth, the application scenario

It is widely used in application scenarios with low speed, low bandwidth, high concurrency, low power consumption and low moving speed requirements.

NB-loT has been successfully commercialized in all walks of life. The application of smart gas meters and smart water meters has exceeded 10000, and the number of smart electric vehicles and smoke sensors will also exceed 10000. In addition to the traditional LPWA industry, it has also been applied to smart agriculture, intelligent manufacturing, POS machines, set-top boxes, bridge detection and other emerging fields.

Intelligent meter reading: intelligent meter reading for water meters, electricity meters and gas meters.

Smart city: intelligent street lamp, garbage management, air detection, weather forecast, intelligent parking, traffic monitoring, congestion prediction and river monitoring.

Recently, the International Telecommunication Union (ITU) announced that NB-IOT&; NR was formally incorporated into the 5G standard, large-scale commercialization of NB-IoT accelerated, and the development of Internet of Things entered the fast lane.

NB-IoT has long been the mainstream technology in the field of cellular Internet of Things because of its wide coverage, low power consumption, low cost and Dalian connection. According to the latest research data of Counterpoint IoT, a market research organization, the number of cellular connections in the global Internet of Things will exceed 5 billion in 2025, and the contribution ratio of NB-IoT will be close to half.

As one of the earliest operators in the world to deploy NB-IoT services, China Telecom has achieved many leading positions in NB network coverage, market scale, industrial applications and platform services. As NB-IoT is brought into the 5G family, NB-IoT industrial ecology will also become an indispensable part of the 5G industrial ecology, and the life cycle and application scenarios of NB-IoT technology will be greatly expanded. Tianyi IOT will take China Telecom's open platform of Internet of Things as the capacity foundation, increase the ecological construction of NB-IoT industry, provide a strong foundation for the implementation of 5G regulations, and realize the coordinated development of eMBB, uRLLC and mMTC scenarios.
