As an important supporting force of the digital economy，IoT industry is attracting more and more attention. G20 countries take mobile IoT and other industries as the pillar of economic recovery，and the Chinese government and scientific research industry are also vigorously promoting the development and innovation of mobile IoT. With the layout and construction of a new generation of information infrastructure in China，typical applications of mobile IoT，such as mobile wearable devices，Internet of vehicles and unmanned aerial vehicles，have developed rapidly，and the corresponding consumer market has begun to take shape. At the same time，the development of mobile IoT has also encountered problems such as chip core technology bottlenecking and backward security technology，so better strategies are needed to help the healthy and orderly development of mobile IoT.
