5G is expected to have a transformative effect on digital connectivity and power the rise of IoT devices, driverless cars, data transfer and the consumer tech of the future.
Therefore, the appetite for equipment and services around 5G is also expected to rise globally. Research from Barclays finds that 5G could even supercharge the UK economy by up to £15.7 billion a year by 2025.
However, 2020 has thrown a considerable spanner into the works: the global economic damage associated with the COVID-19 pandemic notwithstanding, there are now even vigilante efforts to burn down 5G masts due to conspiracy theories that claim they are linked to the virus. So there are likely delays ahead in the deployment of 5G along the way.
Here's our history of the development of the mobile wireless standard, from the 1979 launch of 1G in Japan, to the impending launch of 5G in the UK.

1984 - The first generation
Initially launched in 1979 in Tokyo, by 1984 the first generation (1G) of the wireless standard was rolled out across the whole of Japan by the Nippon Telegraph and Telephone.
In 1983, the US launched its first 1G network using the Motorola DynaTAC mobile phone, with other countries such as the UK and Canada following suit a few years later.
1991 - The second generation
Commercially launched on the Global System for Mobile Communications (GSM) standard in Finland in 1991, 2G brought a wireless standard far superior from anything that the first generation had on offer.
With significantly better wireless connections, 2G provided data services for mobile including SMS text messages and digitally encrypted conversations for the very first time.
Major benefits in the second standard could be seen in the quality of digital voice calls, with a significant reduction in static noise and background crackling.
But even more importantly, 2G made way for a huge cultural shift. Text messages, picture messages, and multimedia messages (MMS) were made possible, creating a whole new way for people to communicate.
This change to a digital system meant that a smaller amount of radio signals were emitted from the handset, meaning that the range of the phone grew smaller, resulting in a need for more mobile cell towers in a smaller vicinity.
This led to a change in the UK’s landscape, with mobile cell towers peppering the UK topography.
2001 - The third generation
First launched in May 2001 for pre-release testing, as with previous generations 3G was available in Japan first, in October 2001.
Foreshadowing the current worries about 5G and the delays in a full roll-out of the 4G network, 3G was released in 2003 in the UK, however there were delays due to the availability of 3G enabled handsets.
Hutchison Whampoa, which owns the mobile network Three, launched in 2003 and provided one of the first 3G handsets, although they came at a price: £400 to be exact, quite a hefty price tag for the time.
According to the BBC, at the time Hutchinson Whampoa said its phones could be used for 'video conferencing and clips from football matches.'
As the second generation did to the first, 3G offered a superior level of connection than its predecessor 2G.
3G users were able to use location-based services, watch mobile TV, participate in video conferencing and watch videos on demand.
2012 - The fourth generation
4G was first introduced to the UK in 2012, with EE rolling out its 4G services to 11 major cities including London, Manchester, Bristol, Birmingham, Cardiff, Edinburgh, Leeds, Liverpool, Sheffield, Glasgow and Southampton.
At the time of its launch, EE said that its 4G network would offer speeds up to 12Mbps, five times faster than the previous generation.
However, 4G has come in for criticism as UK residents complain about the lack of 4G coverage across the UK.
According to the mobile data platform Ogury, UK residents can only access 4G networks 53 percent of the time, making the UK the worst place for 4G coverage in Europe, falling behind both Spain and Italy.
But for those UK residents that do use 4G, this standard offers fast mobile web access, gaming services, high-definition videos and TV support and high-quality video conferencing.
The fifth generation - the early days
Although 5G isn't a commercially available mobile network yet, it is pegged to be considerably faster than its predecessor 4G, and has potential to enable big data industries such as the internet of things and smart homes or cities.
5G is said to offer unlimited data quantities in gigabyte per month and user which could enable users to stream high volumes of high-definition media on their internet enabled device.
In 2008 South Korea developed an R&D program looking at 5G mobile communication systems. Four years later in August 2012, New York University founded NYU WIRELESS, a research centre designed to carry out detailed work on the 5G wireless network.
Closer to home, the EU project Mobile and wireless communications Enablers for the Twenty-twenty Information Society or METIS was created in 2012. Its aim was to research and work towards a working definition of 5G.
Around the same time, the European Commission cofunded the iJOIN EU project that aims to focus on 'small cell technology' which is vital part of 5G technologies.

In a statement, Andy Street, Mayor of West Midlands said: “This announcement is game-changing for the West Midlands economy. This will be the backbone of our future economy and society.
April 2019 - UK authorises Huawei to help build 5G network
Prime minister Theresa May has given Huawei the green light to supply some "non-core" technology, such as antennas, for the UK's 5G infrastructure, following a meeting of the National Security Council.
However, the telecoms giant has been blocked from supplying core parts of the network, days after The Times reported that the CIA had warned the UK and its partners in the Five Eyes intelligence alliance that Huawei has received funding from Chinese state security.
The Telegraph claimed that cabinet ministers Sajid Javid, Jeremy Hunt, Gavin Williamson, Liam Fox and Penny Mourdant had all raised concerns about the decision. Tom Tugendhat, chair of the Foreign Affairs Committee, joined them in questioning the wisdom of the move.
"Allowing Huawei into the UK's 5G infrastructure would cause allies to doubt our ability to keep data secure and erode the trust essential to #FiveEyes cooperation," the Conservative MP wrote in a tweet. "There's a reason others have said no."
Huawei, which already supplies much of the technology used in the UK's 5G infrastructure and has consistently refuted accusations that it's controlled by the Chinese government, welcomed the decision.
It said: "While we await a formal government announcement, we are pleased that the UK is continuing to take an evidence-based approach to its work and we will continue to work cooperatively with the government, and the industry."
May 2019 - 5G roll out could be delayed due to security concerns, warns culture secretary
Culture secretary Jeremy Wright warned that the rollout of 5G in the UK could be delayed if the government chooses to place restrictions on equipment supplied by controversial Chinese telecoms giant Huawei.
"There is certainly the possibility of a delay in the process of the rollout of 5G," Wright said in response to questions during a parliamentary committee. "If you want to do 5G fastest then you do that without any consideration for security. We're not prepared to do that. So I don't exclude the possibility that there will be some delay."
The future of Huawei's involvement in UK's 5G networks will depend on the outcome of a telecom supply chain review, which Wright said would take place "not long from now."
Jake Moore, security specialist at cyber security firm ESET, offered his support for Wright's decision
“If 5G networks communicate our actions to an outside observer secretly, it could be devastating for civil liberties in the UK," he said. "It seems sensible therefore that every protective measure is taken by the government. Even with the best will in the world, our threat intelligence sees attempted hacks on hardware millions of times every single day, so it pays to be cautious."
May 2019 - EE becomes first UK carrier to launch 5G
In May 2019, EE became the UK’s first network provider to launch its 5G network by rolling out in six cities by the end of the month.
By the end of 2019, it had switched on across 50 UK towns and cities such as London, Edinburgh and Birmingham.
“Whether on the street, in a stadium or on location, 5G provides a new dimension that can deliver the speed, efficiency and reliability that outside broadcasting requires,” said Alex Tempest, MD wholesale at BT in a statement.
July 2019 - Vodafone switches on 5G
Vodafone became the UK’s second provider to switch on its 5G network. Launching in seven cities, the network provider also launched in an additional 12 cities by the end of 2019 including Birmingham, Bristol and London.
With a number of partnerships also announced, Vodafone has committed to relying on Huawei's equipment such as the Huawei Mate X smartphone and 5G Gigacube home router.
October 2019 – Additional providers launch 5G network
BT and O2 launched their 5G networks in October 2019. O2 began its rollout by switching on 5G in six UK cities including London, Belfast and Cardiff.
It also plans to have its network live in a total of 20 towns and cities by the end of 2020.
BT, on the other hand, was able to switch on its network in 20 UK towns and cities such as Birmingham, Manchester and London. Its initial launch prioritised BT Plus and Business customers.
Marc Allera, CEO for BT's consumer division said in a statement: “BT Plus is the UK’s first converged fibre and mobile plan and comes with BT’s Keep Connected Promise.
"If a BT Plus customer reports a fault with their home broadband, BT will switch on free, unlimited data on their BT mobiles within an hour and will also send a free 4G Wi-Fi Mini Hub to arrive the next day, with unlimited data to keep customers connected at home while their broadband is repaired. BT Plus customers also benefit from 24/7 dedicated UK and Ireland support.”
January 2020 – UK government allows use of Huawei equipment on 5G networks
Following an ongoing delay due to controversies surrounding Huawei led by the American government, Britain finally announced its decision to allow Huawei equipment to be used within the UK’s 5G networks.
But this decision came with some restrictions: the government officially banned Huawei from supplying its kit to sensitive ‘core’ parts of the network.
Despite the pressure the government faced from President Trump and his US counterparts to keep Huawei out of the network based on security risks, the UK's decision means Huawei can supply 35 percent of its kit.
"Huawei is reassured by the UK government's confirmation that we can continue working with our customers to keep the 5G rollout on track," the firm's UK chief Victor Zhang said in a statement.
"It gives the UK access to world-leading technology and ensures a competitive market."
March 2020 – Samsung launches first 5G smartphone
On March 6, 2020 Samsung announced the launch of its Samsung Galaxy S20 smartphone, the first all-5G smartphone.
