"The peak 5G signal is particularly good." In May 2020, the mountaineers will call at the top of Mount Everest through 5G network. The high-definition video images of the mountaineering team's mountaineering survey have also been shared in real time around the world through the 5G network. This year, the world's highest 5G base station - the 5G base station located at the forward camp of Mount Everest at an altitude of 6500 meters was put into use. In the same year, China's 5G went 534 meters underground, and the country's first underground 5G network was built, creating the record of the world's deepest underground 5G network at that time. Within one year of commercial use, China's 5G set a record of "going up the mountain" and "going into the ground". Now, three years later, how wide is China's 5G coverage? In 2019, the Ministry of Industry and Information Technology of China will issue 5G licenses to operators for the world's largest 5G network, marking the beginning of the first commercial year of 5G. In the same year, the officials of the three major operators announced 5G package rates, and China's 5G commercial process was fully launched. At that time, foreign media pointed out that this marked a key step forward for China to become a technological superpower. The British Broadcasting Corporation (BBC) directly reported the development of China's 5G under the title of "China Launches the World's Largest 5G Network". After the issuance of the 5G license, China's 5G network construction has entered the "fast lane", and China has accelerated into the era of interconnection of everything. In July this year, Monaco became the first country in the world to have a 5G network throughout its territory. In this process, Chinese companies have become one of Monaco's most reliable partners. Since then, the outbreak of New Coronary Pneumonia has made the world see the foresight of China's 5G layout. In 2020, Reuters reported that "during the epidemic, the network load was full. China has withstood this test, and the moderate advance construction of the network obviously contributed. This also gave everyone a taste of the benefits of the 5G network." According to the article of the South China Morning Post in Hong Kong, after the outbreak of the epidemic, a large number of users need faster network connectivity and low latency to support a variety of applications, such as live broadcast and teleconferencing. The long-term development of China's 5G mobile service industry will be accelerated. The report released by the Broadband Development Alliance shows that in the fourth quarter of 2021, the comprehensive average download rate of China's mobile broadband users when using mobile broadband networks to access the Internet has reached 59.34 Mbit/s. This data is less than 20Mbit/s in 2017. The hard-earned 5G leads this "new world" of digital life, which is created by Chinese people. Once upon a time, China's mobile communication industry fell behind others for a long time. Since the 1980s, a new generation of revolutionary technologies has emerged in mobile communications every 10 years. However, the initial 1G is almost a blank for China. It is reported that China's mobile communication technology before 5G has been combed as follows: in 1987, China officially entered the 1G era, and the "big brother" model was deeply rooted in the hearts of the people, but the core technology and standards were firmly mastered by foreign enterprises; In 1994, 2G was launched in China, making it possible to send short messages, and mobile phones became more and more popular; In 2009, the Ministry of Industry and Information Technology issued 3G licenses. Higher bandwidth and more stable transmission speed made mobile Internet a reality,
