The 2020 China Mobile Partner Conference kicked off at the Poly World Trade Expo in Pazhou, Guangzhou. The theme of the conference is "5G is integrated into all industries and digital intelligence leads the future", and demonstrated the achievements of 5G empowerment in multiple industries. In addition to the display of innovative 5G applications that received enthusiastic attention from the attendees, the "China Mobile Medium and Low Speed Internet of Things Business White Paper" (hereinafter referred to as the white paper) was also released on-site at the main forum of the conference under the expectation of the people.

This white paper is based on deepening the industry’s understanding of low- and medium-speed IoT services and promoting the application of low- and medium-speed IoT in vertical industries. It sorts out the main characteristics, typical business characteristics and application scenarios, and enterprise application cases of the low- and mid-speed IoT, and strengthens The three aspects of business research, complementing industry shortcomings and expanding business models discussed the direction of deepening cooperation in the industrial chain, and provided references and references for all walks of life to gain a deeper understanding of the medium and low-speed IoT business.

At the beginning of the white paper, it pointed out the current opportunities and challenges faced by the low- and medium-speed Internet of Things. Under the policy requirements of the Ministry of Industry and Information Technology No. 25 "Notice on Further Promoting the Comprehensive Development of the Mobile Internet of Things", 2G/3G Internet of Things terminals are gradually becoming NB-IoT and LTE Cat.1 is gradually migrated. The medium and low-speed Internet of Things is ushering in major development opportunities. NB-IoT and LTE Cat.1 will go hand in hand to carry a wealth of Internet of Things applications. However, due to the short commercial time of NB-IoT, the LTE Cat.1 network service has just started, and low- and medium-speed IoT applications have not yet blossomed everywhere. The most urgent task is to deepen the industry's understanding of the low-to-medium IoT business and accelerate its application in vertical industries. 

Next, the white paper compares the main features of typical medium and low-speed Internet of Things access technologies, and explains in detail LTE Cat.1 and NB-IoT in terms of network capabilities, wireless air interface characteristics, and evolution direction. Then released application guidance based on business requirements on the comparison results.

▲Comparison of typical low-speed IoT technologies

It can be seen from the above table that NB-IoT meets the requirements of low-power wide-area coverage services in terms of coverage, power consumption, and transmission rate. It is suitable for low-speed IoT applications that require long-distance transmission, small communication data volume, and low latency requirements. ; LTE Cat.1 or eMTC technology is more suitable for services that require high mobility and speed, large data volume, and voice functions; Lora is a representative of wide-area low-power technology that uses unlicensed spectrum, with better performance However, compared with technologies that use authorized frequency bands such as NB-IoT and LTE Cat.1, the latter has higher reliability and credibility. It can provide carrier-grade in terms of identity credential security, authentication mechanism, and key management. Full security guarantee.

Finally, the white paper comprehensively considers various business requirements and network characteristics, divides low- and medium-speed IoT services into the following five categories, and analyzes its core features and suitable technologies for each category of business, and gives typical scenario examples.

Suitable for preferential selection of LTE Cat.1 business scenarios

Delay high-sensitive services, give priority to LTE Cat.1

Common services include: industrial data collection and control terminals, power distribution network monitoring, traffic signal control machines, remote equipment control, and shared massage chairs.

Services with mobility requirements, give priority to LTE Cat.1

Common businesses include: wearable devices, smart electric vehicles, mobile POS, asset tracking, etc.

There are voice-required services, LTE Cat.1 is preferred

Common businesses include: children's watches, smart cameras, low-end 4G mobile phones, etc.

China Mobile hopes to use the release of the white paper as an opportunity to work with industry chain partners to actively promote the standardization of the Internet of Things industry, accelerate the implementation of medium and low-speed Internet of Things business applications, promote mutual benefit and win-win results for multiple parties, and realize the co-creation of ecosystem value for the Internet of Things The healthy development of the industry is escorted.
