The picture shows the Internet of Things technology
Now that China’s strength is revealed, the number of IoT terminals exceeds 1.3 billion. In this process, Huawei can be said to have made a great contribution, because the number of IoT interruptions in China has far exceeded that of the United States and Japan! It seems that this is the real strength. The United States and Japan are really behind this time. Why is China’s Internet of Things technology able to progress so rapidly? In addition to the era of the Internet of Everything brought by 5G, what other driving factors are there?
Huawei’s ability to make such a contribution has a very great relationship with the NB-IoT technology it is now vigorously promoting. As one of the two major technical standards currently used in China, the NB-IoT technical standard has a wide range of related equipment communication network coverage, complex A series of advantages such as high transmission times, extremely low energy consumption of equipment, extremely short data transmission time, and very low equipment cost are widely used by major departments in China.
So, where is the NB-IoT technology standard that Huawei is actively promoting now being used? This technical standard is mainly used in a series of fields such as wireless meter reading systems, smart street lights, smoke sensors and smart door locks. The integrated ecology of the Internet of Things system is used as a base station upgrade module system. In the future, China will be able to expand the NB-IoT system support to at least 100% of cities, 97% of villages and 40% of villages in the country, so as to ensure domestic public goods. Connected devices can do their part in these places.
This means that IoT devices using NB-IoT technology can be effectively used in places fully covered by 4G communication networks. Therefore, such as water and electricity meters, parking meters, smart door locks, Simple smart home appliances that do not require high information interaction, and special equipment such as heartbeat monitors that need to be activated only in emergencies. An NB-IoT communication module with a price of no more than 40 yuan, plus a cheap low-speed traffic card, these devices can complete their work well without additional human intervention, which originally required a lot of manpower and material resources. The business of collecting receipts, or monitoring critically ill patients, which requires nurses to be constantly vigilant, becomes a small problem that can be solved with just a computer or a few alarm bells.
In addition, compared with China’s 2G signal network that has undertaken this business in the past, the NB-IoT base station system based on the 4G technology system only requires network operators to upgrade the firmware of the base station to undertake additional services, and does not require them to spend additional upgrade costs. , In addition to the fact that China has retired 2G base stations due to frequency band requirements, and the NB-IoT system has a greater advantage than 2G networks in dealing with such high-number, large-scale and low-signal output IoT system terminals, Therefore, whether it is a communication network operator, an NB-IoT equipment manufacturer, or a user of the corresponding equipment, they are all very interested in the application and promotion of this technology.
Especially after the existing NB-IoT standard system has been planned into the 5G technical standard, it will continue to be improved as part of the 5G mMTC, and it is likely to replace the wireless network card in the existing smart home products after upgrading to the R16 stage. , the NB-IoT standard led by Huawei will not only be able to dominate in China, but it is also likely to go directly to the world as a global unified standard in the future.
