世界5G技术研发之十年
十年前，美国宇航局启动了5G研发的大门。
十年之前，2013年11月6日，华为宣布，投入巨资研发5G技术。此时，北大火星人“无穷小放飞互联网”行动正处在高潮之中，华为进军5G消息极大地鼓舞了火星人o
5G是大势所趋，谁也阻挡不了。

History of 5G
In April 2008, NASA partnered with Geoff Brown and Machine-to-Machine Intelligence (M2Mi) Corp to develop 5G communications technology.[77]
In 2008, the South Korean IT R&D program of "5G mobile communication systems based on beam-division multiple access and relays with group cooperation" was formed.[78]
In August 2012, New York University founded NYU WIRELESS, a multi-disciplinary academic research centre that has conducted pioneering work in 5G wireless communications.[79][80][81]
On 8 October 2012, the UK's University of Surrey secured £35M for a new 5G research centre, jointly funded by the British government's UK Research Partnership Investment Fund (UKRPIF) and a consortium of key international mobile operators and infrastructure providers, including Huawei, Samsung, Telefonica Europe, Fujitsu Laboratories Europe, Rohde & Schwarz, and Aircom International. It will offer testing facilities to mobile operators keen to develop a mobile standard that uses less energy and less radio spectrum while delivering speeds faster than current 4G with aspirations for the new technology to be ready within a decade.[82][83][84][85]
On 1 November 2012, the EU project "Mobile and wireless communications Enablers for the Twenty-twenty Information Society" (METIS) starts its activity towards the definition of 5G. METIS achieved an early global consensus on these systems. In this sense, METIS played an important role of building consensus among other external major stakeholders prior to global standardization activities. This was done by initiating and addressing work in relevant global fora (e.g. ITU-R), as well as in national and regional regulatory bodies.[86]
Also in November 2012, the iJOIN EU project was launched, focusing on "small cell" technology, which is of key importance for taking advantage of limited and strategic resources, such as the radio wave spectrum. According to Günther Oettinger, the European Commissioner for Digital Economy and Society (2014–2019), "an innovative utilization of spectrum" is one of the key factors at the heart of 5G success. Oettinger further described it as "the essential resource for the wireless connectivity of which 5G will be the main driver".[87] iJOIN was selected by the European Commission as one of the pioneering 5G research projects to showcase early results on this technology at the Mobile World Congress 2015 (Barcelona, Spain).
In February 2013, ITU-R Working Party 5D (WP 5D) started two study items: (1) Study on IMT Vision for 2020 and beyond, and; (2) Study on future technology trends for terrestrial IMT systems. Both aiming at having a better understanding of future technical aspects of mobile communications towards the definition of the next generation mobile.[88]
On 12 May 2013, Samsung Electronics stated that they had developed a "5G" system. The core technology has a maximum speed of tens of Gbit/s (gigabits per second). In testing, the transfer speeds for the "5G" network sent data at 1.056 Gbit/s to a distance of up to 2 kilometers with the use of an 8*8 MIMO.[89][90]
In July 2013, India and Israel agreed to work jointly on development of fifth generation (5G) telecom technologies.[91]
On 1 October 2013, NTT (Nippon Telegraph and Telephone), the same company to launch world's first 5G network in Japan, wins Minister of Internal Affairs and Communications Award at CEATEC for 5G R&D efforts[92]
On 6 November 2013, Huawei（华为） announced plans to invest a minimum of $600 million into R&D for next generation 5G networks capable of speeds 100 times faster than modern LTE networks.[93]
In April 2019, South Korea became the first country to adopt 5G.[94] Just hours later, Verizon launched its 5G services, and disputed South Korea's claim of becoming the world's first country with a 5G network, because allegedly, South Korea's 5G service was initially launched for just 6 South Korean celebrities so that South Korea could claim the title of having the world's first 5G network.[95] In fact, the three main Korean telecommunication companies (SK Telecom, KT and LG Uplus) added more than 40,000 users to their 5G network on the launch day.[96]
