Editing Jubilee line (section)

=== 4G connectivity ===
In March 2020, a [[leaky feeder]] based system was brought online in the Jubilee line tunnels, between Westminster and Canning Town.<ref name=":0">{{Cite press release |title=4G on Jubilee line tunnel section from March 2020|url=https://tfl.gov.uk/info-for/media/press-releases/2019/july/4g-on-jubilee-line-tunnel-section-from-march-2020|access-date=2021-03-12|website=Transport for London }}</ref> The development of this system arose from the Home Office's desire to provide coverage for its new [[Emergency Services Network]] on the London Underground. It allows passengers to receive 4G connectivity both in the tunnels and on station platforms.<ref>{{Cite magazine|last=Kobie|first=Nicole|date=2020-02-05|title=Inside the messy mission to bring 4G to the London Underground|language=en-GB|magazine=Wired UK|url=https://www.wired.co.uk/article/london-underground-4g|access-date=2021-03-12|issn=1357-0978}}</ref>

When opened, it was the first section of London Underground tunnel to receive 4G and 5G connectivity. It was followed in December 2022 and into 2023 by a section of the Central line between [[Queensway tube station|Queensway]] and [[Holland Park tube station|Holland Park]] and the Northern line between [[Archway tube station|Archway]] and [[Mornington Crescent tube station|Mornington Crescent]].<ref>{{Cite web |last= |first= |title=Connected London |url=https://www.tfl.gov.uk/info-for/business-and-advertisers/connected-london |access-date=2023-07-26 |website=Transport for London |language=en-GB}}</ref> TfL intends to deploy the technology across the entire Tube network by the mid-2020s.<ref name=":0" />
