5G generation mobile networks

5G (5th generation mobile networks or 5th generation wireless systems) denotes the next major phase of mobile telecommunications standards beyond the current 4G/IMT-Advanced standards. 5G has speeds beyond what the current 4G can offer.

The Next Generation Mobile Networks Alliance defines the following requirements for 5G networks:

1. Data rates of several tens of megabits per second should be supported for tens of thousands of users
2. 1 gigabit per second to be offered simultaneously to tens of workers on the same office floor
3. Several hundreds of thousands of simultaneous connections to be supported for massive sensor deployments
4. Spectral efficiency should be significantly enhanced compared to 4G
5. Coverage should be improved
6. Signalling efficiency should be enhanced
7. Latency should be reduced significantly compared to LTE

The Next Generation Mobile Networks Alliance feels that 5G should be rolled out by 2020 to meet business and consumer demands.In addition to providing simply faster speeds, they predict that 5G networks also will need to meet the needs of new use cases, such as the Internet of Things as well as broadcast-like services and lifeline communication in times of natural disaster.

Although updated standards that define capabilities beyond those defined in the current 4G standards are under consideration, those new capabilities are still being grouped under the current ITU-T 4G standards.

History

• In April 2008, NASA partnered with Geoff Brown and Machine-to-Machine Intelligence (M2Mi) Corp to develop 5G communication technology
• 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.
• On 8 October 2012, the UK's University of Surrey secured £35M for a new 5G research center, 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.
• 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 intends to ensure an early global consensus on these systems. In this sense, METIS will play an important role of building consensus among other external major stakeholders prior to global standardization activities. This will be done by initiating and addressing work in relevant global fora (e.g. ITU-R), as well as in national and regional regulatory bodies.

• Also on 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 (2014–19), “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”. 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.
• On 12 May 2013, Samsung Electronics stated that they have developed the world's first "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 kilometres.with the use of an 8*8 MIMO.
• In July 2013, India and Israel have agreed to work jointly on development of fifth generation (5G) telecom technologies.
• On 1 October 2013, NTT (Nippon Telegraph and Telephone), the same company to launch world first 5G network in Japan, wins Minister of Internal Affairs and Communications Award at CEATEC for 5G R&D efforts
• On 6 November 2013, Huawei 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.
• On 8 May 2014, NTT DoCoMo start testing 5G mobile networks with Alcatel Lucent, Ericsson, Fujitsu, NEC, Nokia and Samsung.
• In June 2014, the EU research project CROWD was selected by the European Commission to join the group of "early 5G precursor projects". These projects contribute to the early showcasing of potential technologies for the future ubiquitous, ultra-high bandwidth “5G” infrastructure. CROWD was included in the list of demonstrations at the European Conference on Networks and Communications (EuCNC) organized by the EC in June 2014 (Italy).
• At the end of September 2014, Dresden university inaugurates a 5G laboratory in partnership with Vodafone.
• On October 2014, the research project TIGRE5-CM (Integrated technologies for management and operation of 5G networks) is launched with the aim to design an architecture for future generation mobile networks, based on the SDN (Software Defined Networking) paradigm. IMDEA Networks Institute is the project coordinator.
• In November 2014, it was announced that Megafon and Huawei will be developing a 5G network in Russia. A pilot network will be available by the end of 2017, just in time for the 2018 World Cup.
• On 19 November 2014, Huawei and SingTel announced the signing of a MoU to launch a joint 5G innovation program.
• On 28 April 2015, President Recep Tayyip Erdoğan announced Turkey might cancel 4G tender and move straight to 5G from 3G directly in two years.
• On 22 June 2015, Greek government announced to Euro-group council talks that potential licensing 5G and 4G technology would offer 350 million euros earnings, as a result they were criticized for misleading European leaders in producing potential earnings from a technology that is supposed to roll-out after 2020.
• On 8 September 2015, Verizon announced a roadmap to begin testing 5G in field trials in the United States in 2016.
