It is reported that the United States in the 5G network construction has fallen behind China, mainly because it uses non-mainstream 5G caused by millimeter wave technology, the result of 5G network behind the building lead to more than just the use of US consumers late 5G technology, and more it is important to lead the United States in the new field of science and technology behind China.
US 5G network construction lagged behind China
It is reported that since the beginning of the United States the number of base stations 5G completed in less than 15 000, while China's current 5G number of base stations has reached 150,000. American built mostly based 5G 5G base station millimeter wave technology, China's 5G 5G base station is based centimeter wave technology, China's 5G network coverage has been significantly ahead of the United States.
US forced to adopt 5G millimeter wave technology because of the global mainstream 5G IF band is occupied by the US military, US carriers are forced to adopt 5G millimeter wave technology, but based on the coverage of base station 5G 5G millimeter wave technology building is too small, 5G the signal is affected too much, and even rain could obstruct 5G millimeter wave signal, so US carriers built 5G network mainly to improve fixed-line broadband mobile services, mobile communications services instead.
5G network construction slow progress in the United States also associated with its high cost of network construction, the global communications equipment manufacturers among the top four, two major Chinese telecommunications equipment manufacturers Huawei and ZTE equipment provided 5G is the most affordable price, Nokia and Ericsson communications equipment is more expensive, but Huawei and ZTE failed to enter the US market, which leads to cost 5 US carrier base station construction is twice the Chinese operators and more.
The United States has now recognized the many shortcomings 5G millimeter wave technology, so the announcement of nearly $ 15 billion for satellite operators to facilitate their release intermediate frequency band 3.7GHz-42GHz, which means that in fact the United States to abandon 5G millimeter wave technology the selection of the global mainstream 5G centimeter wave technology.
However, China has to speed up the process of building 5G network is expected to be completed end of this year 600,000 5G base station. Today, the United States began to clean up the intermediate frequency band, the success of the release of the intermediate frequency band is in doubt this year, which means that US operators use technology 5G centimeter wave was also the fastest in the obvious beginning, so that in the next 3--5 years China's 5G network construction will be significantly ahead of the United States.
The new science and technology in the United States or behind China
5G technology for the Internet of things, new technologies such as automatic driving preparation, China quickly built a nationwide network 5G will be conducive to China to promote the application of these technologies into practical help China regain the lead in the new technology.
From the current perspective of the development of technology, the United States, at least in the field of autonomous driving technology is ahead of China, especially the American Enterprise Tesla autopilot technology has accumulated more than 1 billion kilometers, it is the world's first application among enterprises in actual use autopilot technology, but the United States 5G network construction progress is slow, it will drag on US companies to stay ahead in these new technologies.
In the 4G era, China Mobile Internet with network coverage on the leading edge (China 4G base stations accounted for nearly half of global proportions) to regain the lead of the US companies, so that American companies have in turn learn from China's Internet innovation and technology. China's current network connections were nearly one billion (until June 2019 only China Mobile's network connections matter had reached 630 million), with the 5G network to quickly cover the whole country, China's Internet of Things will enter a rapid growth stage, China's Internet of things technology leader in the United States will become a reality.
In autopilot technology, China's Baidu in fact technically did not lag behind too many American companies now Baidu is stepping up the promotion of business cooperation with the automobile autopilot technology, with the rapid spread of 5G technology in China, the autopilot technology China is expected to prompt access to applications, so China's autopilot technology is expected to rapidly close the gap with the United States.
Today, the United States turned to support 5G centimeter wave technology, is worried that it might be lagging behind China in the field of new technologies, however, take into account the reality of the situation, the United States pushing the technology it could not shorten the gap with China, perhaps China will be the rapid adoption of 5G in China new technologies the opportunity to catch up with the United States.
