8、G development in China in recent years and my conclusion after research literature. 2. Research and development history February 2013, the EU announced that it would grant 50 million euros to accelerate the development of 5G mobile technology, plans to launch a mature standard in 2020. 23 May 13,201
9、3,South Koreas Samsung Electronics Co., Ltd. announced that it has successfully developed the 5th generation mobile communication (5G) core technology, which is expected to begin in 2020 to commercialization. The technology can transmit data at ultra-high frequency 28GHz to 1Gbps per second speed, a
10、nd the maximum transmission distance of up to 2 km. In contrast, the current fourth generation Long Term Evolution (4GLTE) and services of only the transmission rate 75Mbps. Prior to the transmission bottleneck is widely believed that a technical problem, while Samsung - 3 - Electronics is the use o
11、f 64 adaptive array antenna elements transmission technology to crack this problem. Compared with the transmission speed of 4G technology in South Korea, 5G technology is hundreds of times faster. Using this technique, download a high-definition (HD) movie just need 10 seconds. Back in 2009, Huawei has launched the early research
