In general, 3GPP has a time window of one to several years for a technology from standard completion to real commercial use. For nb-iot, some devices and chip/terminal manufacturers claim that there will be commercial equipment in the second half of 2016; many operators have also released trial commercial systems for smart parking, smart meter reading, etc., or have already clarified Deployment plan for commercial systems.
Many factors contribute to nb-iot fiery
Experts from the China Institute of Information and Communications said that nb-iot will become the unified standard for low-power, large-cover Internet of Things in the world. In fact, in recent years, non-traditional mobile communication companies have used the unlicensed spectrum to deploy and operate IoT networks, which has already brought certain impact to mobile communications. The traditional mobile communication industry requires manufacturers to provide non-public technology competition with unlicensed spectrum as soon as possible. Program. At the same time, 3GPP has designed a new independent narrowband system for the LPWA market, which has basically completed the main technical requirements of nb-iot. A series of reasons have contributed to the fiery heat of the nb-iot.
Operators plan nb-iot strategy
China Telecom is actively following up the development of nb-iot technology, and officially launched research and development on nb-iot key technologies, terminals and services. Its preliminary analysis shows that the capacity of nb-iot users is limited by the random access channel capacity, but can meet System design goals for 52,547 users per community.
Based on the existing research results, China Telecom proposed two deployment ideas of nb-iot. One is the overall solution for the Internet of Things based on the virtualization architecture. Under the demand of a large number of connections, small data packets, power saving, etc., nb-iot Different from the LTE traffic model and function, the core network tends to be deployed independently; the second is to deploy nb-iot based on the full coverage 800MHz LTE network. The base station supports both LTE and nb-iot (nb-iot and 800MHz LTE base stations share baseband, radio frequency and Heavenly resources).
It is reported that China Unicom has also started the pilot and experiment of nb-iot business since 2015, and plans to promote scale application deployment and LTE-eMTC new technology test in 2017.
According to China Unicom, from February 2015 to the first half of 2016, China Unicom launched the IoT smart water meter prototype, built and developed the world's first nb-iot new technology demonstration site in Shanghai, in Guangdong and other places. Continue to promote business exploration. From the second half of 2016 to 2017, China Unicom plans to build six nb-iot field trials, conduct large-scale test verification of N900 & 1800, and gradually scale commercial use. Among them, China Unicom invested a lot of energy in the field of car networking, and established Unicom Zhiwang Technology Co., Ltd., providing a total solution for more than 30 companies that started the car networking service.
As the nb-iot demonstration site of China Unicom, the Shanghai Disney Smart Park has deployed a rich Internet of Things business. In this area, 10 outdoor stations are deployed to cover the entire campus, and a 900MHz independent frequency band network is adopted. As of June 2016, all sites have been opened. Typical applications of the park include smart parking (park parking lot deployment nb-iot vehicle inspection device for parking space management), smart water meter (cooperating with Veolia to pilot nb-iot smart water meter test in the park), and subsequent business to be expanded It also includes intelligent monitoring, flow management, and more.
At the same time, China Unicom is also promoting large-scale networking trials and business trial commercials in Beijing, Shanghai, Guangdong, Fujian and other provinces and cities.
It is reported that in the "5G Test Technology Working Group" led by the TD Industry Alliance, nb-iot has received extensive attention as a pre-technical technology for 5G low-power and large-connection scenarios. The members of the Ministry of Industry and Information Technology also test the nb-iot test scenario. Test requirements and test plans were discussed in depth, and a test plan research report was formed and released recently.
