Millimeter Wave Technology has a new break,China has nearly 700,000 5G base stations: more than double the foreign total.The latest figures, announced by Liu Liehong, vice-minister of industry and information technology, at the China Progress 2020 high-level forum on November 11 evening, show that China has built nearly 700,000 base stations this year, which is more than double the total of 5G base stations in the world outside China.  The number of co-signatories for 5G terminals in China has exceeded 180 million so far.
Steve Mollenkopf, CEO of Qualcomm Enterprises, pointed out at the forum that 5G commercialization will directly create 540,000 office jobs in China in 2020, and the number will increase to more than 8 million in 2030.  5G millimeter-wave technology, which the industry once thought could not be used in mobile communications, has also achieved a milestone in recent days, he said.
At the forum, Liu Liehong pointed out that the outbreak has accelerated the application of many new technologies.  In the year since I spoke, China has accelerated the construction, progress, and application of 5G. In the year since I spoke, China has built nearly 700,000 base stations, "which is more than the total of the whole world outside China combined, and more than twice the total of 5G base stations outside China."
In addition, he said, the number of co-signatories of 5G terminals in China has exceeded 180 million so far, and the satisfactory infrastructure has facilitated many new applications based on 5G, such as during the epidemic period.  In the field of intelligent education, many new standard models and formats have been produced, such as 5G+ ultra-high-definition long-range interaction teaching, AR/VR immersion teaching, and all-information classroom.
Steve Mollenkopf, the CEO of Qualcomm, a close play in the communications sector, said in a speech on Wednesday that Qualcomm believes that 5G will have a profound and disruptive impact, from transportation to health care to education, and will unlock unlimited potential in unimagined areas.
In a year when Chinese mobile operators rolled out 5G services and deployed 690,000 base stations, he noted that by the end of July they had successfully signed up 160 million units, an astonishing feat that no operator anywhere else in the world has managed to achieve.
The reality is that 5G deployment around the world is also accelerating.  In just one year since the deployment of the first batch of 5G networks, more than 95 operators around the world have launched 5G services in more than 40 countries and regions, and an additional 300 operators have invested in the deployment of 5G technology. Research shows that by 2025, China's network co-operations are expected to account for 30% of the world's total.  It is estimated that 5G commercialization will directly create 540,000 office jobs in China by 2020, and the number will increase to more than 8 million by 2030.
Notably, according to Steve Mollenkopf, 5G Millimeter Wave Technology, which the industry once thought would be impossible to use in mobile communications, has also achieved a milestone break in recent days.
He said that Qualcomm has recently completed all necessary 26GHz band 5G millimeter-wave performance and RF technology tests at the China Academy of Information and Communications Research's MTNET Lab.  The deployment of a 5G millimeter wave will help China deal with problems such as the digital divide.  For example, it can provide fiber-optic wireless connection speed through schools, hospitals, and other institutions determined by millimeter waves to solve the "last one thousand meters" problem in rural areas.
In addition to this, in recent days, Qualcomm successfully implemented the first extended-range 5G NR millimeter-wave numerical call in the United States, with a communication range of more than 5 kilometers and an efficiency of more than 100 Mbps.  "This landmark project demonstrates the value of millimeter-wave power in helping operators expand their network coverage economically and efficiently."
Previous research and development on 5G in the United States have focused on high-frequency millimeter-wave bands because the medium and low-frequency bands are already occupied.  However, the high-frequency waveband is easy to be blocked, the penetration experience is poor, the coverage range is small, the need for a large number of base stations, the cost is too high, and has been widely regarded as negative in the industry.5G applications represented by China are mainly concentrated in the low and middle-frequency bands below 6GHz, such as China Mobile's 2.6G and 4.9G, Unicom, and Telecom's 3.5g band.  And the radio and television are to receive 700 meters of the band.
