According to foreign media reports, Deutsche Telekom (DT) claimed to “activate†the world's first fully standardized NB-IoT network in Germany, further marking the development momentum of this emerging technology. It is understood that Deutsche Telekom plans to further announce its NB-IoT strategy in the news demonstration on technology and smart parking services held on October 20th. Huawei and Deutsche Telekom's Dutch subsidiary T-Mobile Netherlands will also participate in the demonstration.
NB-IoT is one of several technologies that can meet the so-called low-power, wide-area (LPWA) network; it can support services such as smart metering and asset tracking more economically than traditional cellular standards. According to McKinsey's latest research results, IoT has broad application prospects. It is expected that the Internet of Things will reach 11.1 trillion US dollars in 2025, including nine sectors, public utilities, smart cities, and transportation. McKinsey believes that NB-IoT will reach 42 billion US dollars. The scale reached 420 million connections. NB-IoT is suitable for public utilities, smart cities, public health, transportation and education.
At present, the world's major operators including the Vodafone Group in the UK have committed to develop NB-IoT technology.
Compared with traditional IoT technologies such as Bluetooth and WiFi, NB-IoT technology has obvious advantages: large capacity, wide coverage, low power consumption, low cost and high stability. In terms of capacity, NB-IoT has 50 times to 100 times higher uplink capacity than 2G/3G/4G, which provides strong support for the burst of access hardware. In terms of power consumption, the cost of the chip will be significantly reduced due to lower requirements for RF and PA required for low speed and low bandwidth.
The NB-IoT protocol has been approved by 3GPP since June. Since the core protocol was frozen, all aspects have progressed rapidly. It is expected that Huawei will realize mass production of NB-IoT commercial chips in the fourth quarter of this year. The three major operators will conduct related communications in the second half of this year to next year. Network deployment is expected to complete commercial deployment within the country by 2018. At the 2016 China Smart Terminal Technology Conference held at the end of August, China Unicom [-1.25% Fund Research Report] indicated that it has launched a large-scale NB-IoT field experiment plan, with the goal of scale deployment in multiple cities for commercial use next year. ready. Hu Yun, director of the Internet of Things Research and Development Center of China Unicom Network Technology Research Institute, said that this year is China Unicom's NB-IoT pilot year, and next year will be the first year of commercial use.
In addition, Shen Shaoai, deputy general manager of the technical department of China Telecom Group, said earlier that China Telecom will use 800M as the first frequency band for deploying NB-IoT. The low frequency spectrum facilitates the large link and coverage capabilities required for narrowband IoT service applications. Based on the existing IMT network reusable site collection supporting resources, the NB-IoT can be quickly deployed by software upgrade or adding some hardware. In addition, equipment manufacturers such as Huawei and ZTE are also actively deploying NB-IoT services. Huawei has released an end-to-end NB-IoT solution for the world, helping operators to use NB-IoT technology to open up new market space and provide comprehensive technical and commercial support for the upcoming IoT large-scale commercial. Huawei plans to launch a large-scale commercial trial in the fourth quarter, and officially launched large-scale commercial use at the end of December this year.
With the development of standards and the deployment of operators, the NB-IoT industry will take the lead in applications such as smart water meters and wearable devices.
