On the 19th, at the JDD-2019 Jingdong Global Technology Explorer Conference hosted by Jingdong Group, the Chinese Academy of Engineering, the former vice president of the Chinese Academy of Engineering, and the president of the China Internet Society, He Hezhen, said that 5G widely used air separation technology and utilized many The antenna increases the overall capacity proportionally, plus a wider frequency and physical layer improvement, which increases the peak rate of 5G by 4 times over 4G, increases the user experience data rate by 10 times, and increases the screen efficiency by 3 times. At 5G, AIOT will lead the transformation of the supply chain, bringing many changes in the fields of industrial Internet, robotics, car networking, blockchain and so on. He further pointed out that in the field of blockchain, product traceability can be better achieved. Traditional product traceability does not necessarily guarantee the accuracy of the entire product data. Using blockchain and 5G, good data collection can be achieved to avoid artificial fraud.
