A, 5G definition
5G refers to the fifth generation of mobile communications technology, is the latest generation of cellular mobile communications technology, is an extension of the 4G, 3G and 2G system after the 5G performance objectives are high data rates, reduce latency, energy savings, reduce costs, improve system capacity and large-scale device connectivity.
5G applications are not just for cell phones, but will be geared toward the future of VR and AR, smart cities, smart agriculture, industrial internet, connected cars, drones, smart homes, smart healthcare, drones, emergency security, and much more while enhancing the use of communications. A simple understanding of 5G is to connect everything you want at the fastest speed and with the highest efficiency.
Two, change
1, car networking and automatic driving
Car networking technology has experienced the use of wired communications roadside unit (road signs) and 2G/3G/4G network to carry the stage of in-vehicle information services, is relying on high-speed mobile communications technology, and is gradually entering the era of automatic driving.
According to the automotive development plans of China, the United States, Japan and other countries, relying on 5G networks with higher transmission rates and lower latency, the mass production of self-driving cars will be fully realized in 2025, with a market size of 1 trillion U.S. dollars .
2, Surgery
On January 19, 2019, a Chinese surgeon performed the world's first remote surgical operation using 5G technology. The doctor used a 5G network in Fujian Province to maneuver a robotic arm in a remote area 30 miles (48 kilometers) away to perform the surgery. During the procedure performed, the surgeon used the 5G network to remove the liver of an experimental animal thanks to a delay of just 0.1 seconds.
Other benefits of 5G technology include a dramatic reduction in download times, with download speeds rising from about 20 megabytes per second to 50 gigabytes per second - the equivalent of downloading more than 10 high-definition movies in one second.
The most immediate application of 5G technology is likely to be to improve the video-calling and gaming experience, but robotic surgery is likely to hold great promise for specialized surgeons performing operations on people in need around the world.
5G technology will open up many new areas of application for which previous mobile data transmission standards were not fast enough. the speed and lower latency of 5G networks meets the requirements for telepresence, and even telesurgery, for the first time.
3, smart grid
Because of the high security requirements of the grid and the breadth of the full coverage characteristics, the smart grid must be 99.999% high reliability in the massive connection and wide coverage of the measurement and processing system; large number of end devices accessed at the same time, ultra-low latency of less than 20 ms, as well as the terminal depth of coverage, signal smoothness, etc. is the basic requirements for its safe work. The requirements of the system are as follows

On May 8, 2014, NTT DoCoMo, a Japanese telecom operator, announced that it will begin testing a high-speed 5G network that will exceed the capacity of the existing 4G network by 1,000 times, with transmission speeds expected to increase to 10 Gbps, in cooperation with six vendors, including Ericsson, Nokia, and Samsung. Outdoor testing is expected to begin in 2015, with operations expected to begin in 2020.
On September 7, 2015, U.S. mobile operator Verizon Wireless announced that it will begin trials of its 5G network in 2016, with full commercialization in 2017 in select U.S. cities. China's 5G technology research and development trials will be conducted in 2016-2018, and are divided into three phases of implementation: 5G key technology trials, 5G technology program verification and 5G system verification.
