Recently the US Federal Communications Commission FCC plans to cost about $ 14.9 billion from the satellite communications business recovery 3.7GHz ~ 4.2GHz band for 5G network construction, which means that the United States has finally recognized that defects 5G millimeter wave technology, will introduce 5G centimeter wave 5G network technology to build.
5G 5G centimeter and millimeter wave technology wave technology has sparked controversy, but the world outside the United States have adopted the basic 5G centimeter wave technology, mainly because of the greater coverage 5G centimeter wave technology, lower cost of network construction.
US development of 5G millimeter wave technology has multiple considerations, first US satellite communications and military units have been used intermediate frequency band, these departments do not want to release these bands, which forced the United States had to develop 5G millimeter wave technology.
Second, is the world's four largest communications equipment manufacturers are China's Huawei and ZTE, Nokia and Ericsson in Europe, they are developing 5G centimeter wave technology, US companies hope to gain greater patent therefore another way to develop 5G millimeter wave technology, trying to thereby obtaining more right to speak 5G technology.
In the United States, pushing the US operators are trying to adopt 5G 5G millimeter wave technology to build the network, but they soon discovered diffraction 5G millimeter wave technology, diffraction ability is really bad, if covered with a millimeter wave technology to build 5G American 5G network will need to invest that amount of money days, the face of this difficult now lead to most US carriers to choose the original part of the construction of 4G 5G band network.
By now the FCC has finally recognized that technical deficiencies exist 5G millimeter wave technology, and finally decided to release intermediate frequency band for the construction of 5G networks, millimeter wave technology 5G main push of the United States have made such a choice, no doubt means 5G millimeter wave technology He will soon be abandoned.
Huawei is precisely 5G centimeter wave technology leader, its founder, Ren Zhengfei, Huawei said in the company had decided many years ago the development of 5G centimeter wave technology, it has a leading edge technology, but now with the United States 5G centimeter wave technology unequivocal support, Huawei will undoubtedly be the biggest beneficiaries.
2G, 3G era is dominated by the United States, 4G technology is the outcome of cooperation between China and Europe, and now 5G technology once again won by China and Europe, representing the US influence in mobile communications technology is further weakened, which is no doubt the United States It is a major blow.
如此也就不难理解为何美国要多次对华为出手了，为此它对欧洲各国游说希望欧洲各国不要采用华为的5G设备，然而今年以来英国、德国已陆续表示对华为的支持，这都凸显出华为在5G厘米波技术上的所拥有的优势日渐获得认可。
