Telecommunications in the United Kingdom
Template:Use dmy dates Template:Use British English
Telecommunications in the United Kingdom have evolved from the early days of the telegraph to modern fibre broadband and high-speed 5G networks.<ref>Template:Cite web</ref>
History
[edit]
National Telephone Company (NTC) was a British telephone company from 1881 until 1911, which brought together smaller local companies in the early years of the telephone. Under the Telephone Transfer Act 1911 it was taken over by the General Post Office (GPO) in 1912.<ref>Template:Cite web</ref><ref>Template:Cite web</ref>
The telephone service in the United Kingdom was originally provided by private companies and local city councils, but by 1912–13<ref>Template:Cite web</ref> all except the telephone service of Kingston upon Hull, Yorkshire and Guernsey had been bought out by the General Post Office. Post Office Telephones also operated telephone services in Jersey and the Isle of Man until 1969 when the islands took over responsibility for their own postal and telephone services. Post Office Telephones was reorganised in 1980–81<ref>Template:Cite web</ref> as British Telecommunications (British Telecom, or BT), and was the first nationalised industry to be privatised by the Conservative government. The civil telecoms monopoly ended when Mercury Communications arrived in 1983.
Broadcasting of radio and television was a duopoly of the BBC and Independent Broadcasting Authority (IBA): these two organisations controlled all broadcast services, and directly owned and operated the broadcast transmitter sites. Mobile phone and Internet services did not then exist. Broadcast transmitters, which belonged to the BBC and IBA, were privatised during the 1990s and now belong to Babcock International and Arqiva.<ref>Template:Cite web</ref>
British Rail Telecommunications was created in 1992 by British Rail (BR). It was the largest private telecoms network in Britain, consisting of 17,000 route kilometres of fibre optic and copper cable which connected every major city and town in the country and provided links to continental Europe through the Channel Tunnel.<ref>Template:Cite web</ref> BR also operated its own national trunked radio network providing dedicated train-to-shore mobile communications, and in the early 1980s BR helped establish Mercury Communications', now C&WC, core infrastructure by laying a resilient 'figure-of-eight' fibre optic network alongside Britain's railway lines, spanning London, Bristol, Birmingham, Leeds and Manchester.
Regulation of communications has changed many times during the same period, and most of the bodies have been merged into Ofcom, the independent regulator and competition authority for the UK communications industries.<ref>Template:Cite book</ref>
Infrastructure
[edit]
Domestic trunk infrastructure
[edit]All communications trunks are now digital. Most are carried via national optical fibre networks. There are several companies with national fibre networks, including BT, Level 3 Communications, Virgin Media, Cable & Wireless, Easynet and Thus. Microwave links are used up to the 155 Mbit/s level, but are seldom cost-effective at higher bit rates.Template:Fact
International trunks
[edit]The UK is a focal point for many of the world's submarine communications cables, which are now mostly digital optical fibre cables.<ref>Template:Cite web</ref>
Broadcast transmission
[edit]Arqiva provide services for content contribution, coding and multiplexing, distribution to the transmitter sites as well as maintaining the national transmitter network itself for television.<ref>Template:Cite web</ref>
Arqiva's radio network transmits 380 analogue and 300 digital radio stations across the UK via 1,450 radio transmitter sites.<ref>Template:Cite web</ref> They operate the two commercial national multiplexes – Digital One and Sound Digital – and provide transmission services to the BBC for their national DAB (Digital Audio Broadcasting) multiplex as well as spectrum planning expertise for small-scale DAB license applicants. They also provide managed transmission services (MTS) and network access (NA) services for both analogue and digital channels from over 1,450 sites across the UK and they also provide contribution, coding and multiplexing and distribution for national and local DAB multiplexes.<ref>Template:Cite web</ref>
Services
[edit]Television and radio broadcasting
[edit]Radio
[edit]In 1998, there were 663 radio broadcast stations: 219 on AM, 431 on FM and 3 on shortwave. There were 84.5 million radio receiver sets (1997). TodayTemplate:When there are around 600 licensed radio stations in the UK.Template:Fact
Television
[edit]Currently, the United Kingdom has a collection of free-to-air, free-to-view and subscription services over a variety of distribution media, through which there are hundreds of channels for consumers as well as on-demand content.
Since 24 October 2012, all television broadcasts in the United Kingdom have been in a digital format, following the end of analogue transmissions in Northern Ireland. Digital content is delivered via terrestrial, satellite and cable, as well as over IP.
Internet
[edit]The country code top-level domain for United Kingdom web pages is .uk. Nominet UK is the .uk. Network Information Centre and second-level domains must be used.
At the end of 2004, 52% of households (12.6 million) were reported to have access to the internet (Source: Office for National Statistics Omnibus Survey). broadband connections accounted for 50.7% of all internet connections in July 2005,<ref>Template:Cite news</ref> with one broadband connection being created every ten seconds.<ref>Template:Cite news</ref> Broadband connections grew by nearly 80% in 2004. In 1999, there were 364 Internet service providers (ISPs). Public libraries also provide access to the internet, sometimes for a fee.
In 2017, 90% of households were reported to have access to an internet connection. This percentage shows an increase in internet access from 80% in 2012 and 61% in 2007.<ref>Template:Cite web</ref>

First generation networks
[edit]- Cellnet was originally jointly owned by British Telecom and Securicor. BT eventually bought out Securicor's stake. The network became BT Cellnet and was then demerged to become O2.<ref>Template:Cite news</ref>
Both companies ran ETACS analogue mobile phone networks.
2G
[edit]2G is being phased out and replaced with 4G and 5G. The four mobile network operators have agreed to switch off their 2G networks by 2033.<ref>Template:Cite web</ref>
3G
[edit]The four 2G companies all won 3G licences in a competitive auction, as did a new entrant known as Hutchison 3G, which branded its network as 3.
3G networks were rolled-out during the early 2000s. They made it possible to access the internet through a mobile phone for the first time.<ref>Template:Cite web</ref>
Mobile network operators are in the process of switching off their 3G networks. EE,<ref>Template:Cite web</ref> Vodafone<ref>Template:Cite web</ref> and Three<ref>Template:Cite web</ref> have completed their switch-offs, with O2 expected to follow in 2025, starting with the City of Durham in April.<ref>Template:Cite web</ref>
4G
[edit]4G/Long-term evolution (LTE) services are extensive. EE launched their 4G network in October 2012, using part of their existing 1800 MHz spectrum. O2 launched its 4G network on 29 August 2013, initially in London, Leeds and Bradford with a further 13 cities added by the end of 2013.<ref>Template:Cite web</ref> Vodafone commenced its 4G services on 29 August 2013, initially in London with 12 more cities added by the end of 2013.<ref>Template:Cite web</ref> Three commenced 4G services in London, Birmingham, Manchester, Reading, Wolverhampton and the Black country in December 2013 albeit with a limited number of subscribers to evaluate its implementation. Full rollout to remaining subscribers commenced on 5 February 2014 on a phased basis via a silent SIM update.<ref>Template:Cite web</ref> As a condition of acquiring part of EE's 1800MHz spectrum for 4G use, Three were unable to use it until October 2013.<ref>Template:Cite news</ref><ref>Template:Cite news</ref>
5G
[edit]5G is currently being rolled-out by mobile network operators. The first commercial networks went live in major UK cities in 2019.<ref>Template:Cite journal</ref>
EE was the first to launch their 5G network, initially in London, Cardiff, Edinburgh, Belfast, Birmingham and Manchester on 30 May 2019,<ref>Template:Cite web</ref> followed by Vodafone in Birmingham, Bristol, Cardiff, Glasgow, Manchester, Liverpool and London on 3 July 2019.<ref>Template:Cite web</ref> Three launched their 5G service on 19 August 2019, initially for broadband customers in London.<ref>Template:Cite web</ref> O2 was the last network to launch a 5G network; the rollout of which began in October 2019, starting with Belfast, Cardiff, Edinburgh, London, Slough and Leeds.<ref>Template:Cite web</ref>
Numbers
[edit]When mobile cellular networks were first rolled out, there were various numbers beginning 03 through 09 in use, these being interspersed between the various existing geographic area codes. As part of the Big Number Change, all mobile (as well as pager and personal) numbers were brought together under the 07 range. The table below shows the initial ranges of numbers that were allocated as part of the new 07 range, which began on 30 September 1999.<ref>Template:Cite web</ref>

Mobile phone services
[edit]Template:See also There are four mobile network operators in the United Kingdom - O2, EE, Vodafone, and Three.
The number of active mobile subscriptions (excluding M2M) was 89.6 million at the end of Q2 2024, up 2.1 million (2.4%) from the year before.<ref>Template:Cite web</ref>
In 2011 there were 82 million subscriptions in the UK.<ref name="ofcom">Template:Cite web</ref> There were 76 million in 2008<ref>Template:Cite web</ref> and 55 million in January 2005.
All of the mobile network operators sell mobile phone services directly. In addition, there are a large number of mobile virtual network operators (MVNOs). Examples include Tesco Mobile, spusu, Lebara, and SMARTY.
Fixed telephony
[edit]Landlines
[edit]BT is still the main provider of fixed telephone lines<ref name=":0">Template:Citation</ref> and it has a universal service obligation, although companies can contract Openreach to install a phone line on their behalf, rather than telling the customer to get BT to install it, then transfer over.Template:Fact
Sky is the second biggest player in the residential telephone line market.<ref name=":0" /> Other companies provide fixed telephone services such as Virgin Media, Vodafone and EE.<ref name=":0" />
In Q2 2024, the total number of fixed voice lines (including PSTN, ISDN and VoIP) was 25.4 million, a fall of 2.6% compared to the previous year. Total fixed-originated call volumes decreased by 1.22 billion minutes (21.5%) to 4.46 billion minutes.<ref>Template:Cite web</ref>
The switched telephone network (both PSTN and ISDN) is due to be turned off on 31 January 2027, after customers are moved to voice over IP services.<ref>Template:Cite web</ref><ref>Template:Cite web</ref>
Numbering
[edit]There is a set numbering plan for phone numbers within the United Kingdom, which is regulated by the Office of Communications (Ofcom), which replaced the Office of Telecommunications (Oftel) in 2003. Each number consists of an area code – one for each of the large towns and cities and their surroundings – and a subscriber number – the individual number.
