1、无线通信5G介绍英文论文-A-Brief-Introduction-About-5G-Network 作者： 日期：A Brief Introduction About 5G NetworkJiaAbstractWith the rapid development of wireless technologies, theconcept of the Fifth Generation (5G) wireless communication system started to emerge. But most people know little about 5G，including some
2、aspects of 5G wireless communication networks ,just like what 5G is about: what are the building blocks of core 5G system concept, what are the main challenges and how to tackle them. Besides, A number of countries and organizations working on 5G, 5G development situation in China is of concern to e

In the rest of paper I will show how 5G development in China in recen
8、t years and my conclusion after research literature.2. Research and development historyFebruary 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. 23May 13,2013,South Koreas Samsung Electronics
9、 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, and the maximum transmission distan
10、ce 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 Electronics is the use of 64 adaptive array antenna elements tra
11、nsmission 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 related t
12、echnologies, and to show the prototype of the 5G base in later years.In November 6, 2013,Huawei announced that it would invest $600 million in 2018 for the 5G technology development and innovation, and predicted that users will enjoy 20Gbps commercial 5G mobile networks in 2020.May 8, 2014, the Japa
13、nese telecom operator NTT DoCoMo announced officially, Ericsson ,Nokia, Samsung and other six manufacturers to work together, began testing override 1000 times than existing 4G networks the carrying capacity of the high-speed network 5G network, the transmission speed is expected to 10Gbps. Outdoor
14、testing scheduled to commence in 2015, and expects to begin operations in 2020.3March 1, 2015, the British Daily Mail reported that the British 5G network has successfully developed and tested for data transmission within 100 meters per second data transfer of up to 125GB, is 6.5 times the 4G networ
