The difference between China Mobile and Telecom NB

1. What is NB-IoT?

Refers to Narrow Band-Internet of Things (Narrow Band-Internet of Things) technology. NB-IOT focuses on the Low Power Wide Area (LPWA) IoT market and is an emerging technology that can be widely used around the world. China Telecom's NB-IoT network is based on the 800MHz low-frequency golden band and has built the world's largest NB-IoT network. It includes number segments such as 10649, 14100 and 14101, and supports basic communication services such as SMS and wireless data.

2. Product capabilities

Data services: Support data access service capabilities.

SMS service: supports SGS SMS communication capabilities.

NB gateway service: China Telecom provides NB gateway to achieve seamless connection with the NB-IoT network to meet the fast access of a large number of high-concurrency devices, and at the same time realize resource subscription, storage, forwarding and command delivery to the devices. Send and other functions; NB gateway has rich API interfaces to help users quickly develop and open platform-based related capabilities.

3. Product features:

Large connections: Each base station area can support 100,000 connections. Compared with existing wireless technology, NB-IoT can increase 50 to 100 times. number of accesses.

Wide coverage: The gain is 20dB higher than the traditional GSM network. The coverage area provided by one base station is 10 times that of ordinary ones, covering underground areas and inside buildings that are difficult to cover with traditional networks.

Low power consumption: Save power by reducing unnecessary signaling and not accepting paging information in the PSM state. Ultra-low power consumption. Ordinary batteries have a service life of more than 10 years.

Easy to use: Similar to the standard IoT card in appearance, volume and size, it is compatible with the original IoT card usage, and provides plug-in card, patch and eSIM usage.

Simple billing: Provides annual billing, is simple to move, and supports multiple billing cycles including 10-year long-term billing.

Low cost: The industrial chain is mature and the chips are low-cost.

4. Application Scenarios

Widely applicable to application scenarios with low speed, low bandwidth, high concurrency, low power consumption and low mobile speed requirements.

NB-loT has been successfully commercialized in all walks of life. The number of smart gas meters and smart water meters has exceeded 10 million, and the number of smart electric vehicles and smoke detector connections will also exceed 10 million. In addition to being used in the traditional LPWA industry, it has also begun to be used in emerging fields such as smart agriculture, smart manufacturing, POS machines, set-top boxes, and bridge inspection.

Smart meter reading: smart meter reading for water meters, electricity meters, gas meters, etc.

Smart city: smart street lights, waste management, air detection, weather forecast, smart parking, traffic monitoring, Congestion prediction, river monitoring.

Recently, the International Telecommunications Union (ITU) announced that NB-IoT & NR have been officially included in the 5G standard. The large-scale commercial use of NB-IoT is accelerating, and the development of the Internet of Things has entered the fast lane.

With the characteristics of wide coverage, low power consumption, low cost, and large connections, NB-IoT has long become a mainstream technology in the field of cellular IoT. According to the latest research data from market research firm Counterpoint IoT, the number of global IoT cellular connections will exceed the 5 billion mark in 2025, of which NB-IoT will contribute nearly half.

As one of the first operators in the world to deploy NB-IoT business, China Telecom has achieved many leaders in NB network coverage, market size, industry applications, platform services, etc. With the inclusion of NB-IoT into the 5G family, the NB-IoT industry ecosystem will also become an indispensable and important part of the 5G industry ecosystem, and the life cycle and application scenarios of NB-IoT technology will be greatly expanded. Tianyi IoT will use China Telecom's IoT open platform as its capability base to increase the construction of the NB-IoT industry ecosystem, provide a strong foundation for the large-scale implementation of 5G, and realize the coordinated development of various scenarios such as eMBB, uRLLC and mMTC.
