Huawei and DOCOMO (a Japanese mobile network) teamed up in December 2016 to conducted the world's first 5G large-scale field trial. Using the 4.5 GHz frequency band, both companies recorded data transfer speeds of 11.29 Gbps, which is about 40 times faster than the current 4G .Tuanzie hapa mkuu,labda kama mimi ndio sielewi...

This article is about the latest telecommunication standard. For other uses, see 5G (disambiguation).
5G is generally seen as the fifth generation cellular network technology that provides broadband access. The industry association 3GPP defines any system using "5G NR" (5G New Radio) software as "5G", a definition that came into general use by late 2018. Others may reserve the term for systems that meet the requirements of the ITU IMT-2020, which represents more nations. 3GPP will submit their 5G NR to the ITU. [1] It follows 2G, 3G and 4G and their respective associated technologies (such as GSM, UMTS, LTE, LTE Advanced Pro, etc.).

IntroducedApril 2019
The first fairly substantial deployments were in April 2019. In South Korea, SK Telecom claimed 38,000 base stations, KT Corporation 30,000 and LG U Plus18,000; of which 85% are in six major cities.[2] They are using 3.5 GHz (sub-6) spectrum in non-standalone (NSA) mode and tested speeds were from 193 to 430 Mbit/s down.[3] 260,000 signed up in the first month and the goal is 10% of phones on 5G by the end of 2019.[4]
Verizon opened service on a very limited number of base stations in the US cities of Chicago and Minneapolis using 400 MHz of 28 GHz millimeter wave spectrum in NSA mode. Download speeds in Chicago were from 80 to 900 Mbit/s. Upload speeds were from 12 to 57 Mbit/s. The round-trip delay time was 25 milliseconds.[5] It was reported in May 2019 that Verizon's 5G service would regularly hit 1 Gbit/s in some locations. [6][7]
Five companies sell 5G radio hardware and 5G systems for carriers: Huawei, ZTE, Nokia, Samsung, and Ericsson.[8][9][10][11][12][13]

In April 2008, NASA partnered with Geoff Brown and Machine-to-Machine Intelligence (M2Mi) Corp to develop 5G communications technology.[85]
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.[86]
In August 2012, New York University founded NYU WIRELESS, a multi-disciplinary academic research centre that has conducted pioneering work in 5G wireless communications.[87][88][89]
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.[90][91][92][93]
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.[94]
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".[95] 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.[96]
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.[97][98]
In July 2013, India and Israel agreed to work jointly on development of fifth generation (5G) telecom technologies.[99]
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[100]
On 6 November 2013, Huaweiannounced 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.[101]
In April 2019, South Korea became the first country to adopt 5G.[102] Just hours later, Verizon launched its 5G services in the United States, 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.[103] In fact, the three main South Korean telecommunication companies (SK Telecom, KT and LG Uplus) added more than 40,000 users to their 5G network on the launch day.[104]
