This is one for the smartphone junkies. Actually, that’s pretty much everyone – Ofcom proudly announced in 2015 that the UK is a ‘smartphone society’, with 80 per cent of adults owning a smartphone – so the vast majority of you will be thrilled to hear about the new initiative that will see half a million small cell transmitters installed around London.

These mini-masts will be attached to street furniture (that is, lampposts and so forth) and publicly-owned buildings, ensuring vastly improved network coverage among the capital’s winding streets. This big reveal follows mayor Sadiq Khan’s pledge last year to boost digital connectivity and deal with London’s ‘not-spots’.

The idea is hardly new: the private sector was launching similar projects as far back as 2006. But these initiatives have always been piecemeal, coming from individual suppliers.

This new iteration will see collaboration between city hall and local councils, allowing for much wider coverage than that afforded by the odd privately owned office or pub. Using smaller transmitters brings another advantage: they are much easier to install, and don’t require road closures or big structural changes inherent in larger cell masts.

Other public bodies in the capital have dabbled in this area. The City of London Corporation was wildly successful last year in establishing a publicly accessible free-to-use wifi across the whole of the Square Mile. Replacing the existing Sky Wifi, the new network runs off 150 wireless access points attached to the City’s street furniture. Amazingly, the whole project was delivered in just nine months. Khan is hoping to mirror this efficiency with contracts awarded for the mini-mast rollout by Summer this year.


London’s future small cell network will be all important when the next generation 5G network finally arrives. That’s due some time in the early 2020s, and telecoms company O2 reckons that, by 2026, it will add over £7bn a year to the economy. It’s sweet they think that everyone will be working hard on the buses and tube lines (yes it’s going underground as well), when really we’ll be spending our commutes streaming Netflix and sending snarky tweets.

As stoked as we should be for this technological makeover, it is long overdue. A report from the London Assembly last year found the capital’s phone coverage was abysmal. Under 75 per cent of London has 4G coverage, placing it in the bottom five of all UK cities; it ranks 30th out of 63 on high speed broadband, too. The report concluded with a warning, that its shoddy phone connections meant that, “London’s success and international competitiveness are under threat”.

These failings didn’t sneak up on us. During the 2012 Olympics, networks became overloaded through heavy use. And as Londoners use their smartphones to watch ever more Netflix these mini-mast improvements arrive in the nick of time.

Khan is also reaching out to Londoners to help form his Smart London Plan, which will look at how technology can improve life in the capital. Good to see the capital is finally joining the 21st century.
