UK mobile broadband infrastructure

The UK was
among the first countries in Europe to receive a consumer level 3G network,
launched by the mobile wing of British Telecom in 2003. Up until that point we
had, like everywhere else, struggled along with a 2G service – fine for voice
and texts but internet access could be painful even compared to dial-up.

It wasn’t
until 3G went live that mobile broadband became a real possibility, and it’s
proven popular: the UK telecoms regular Ofcom
estimated in 2012 that 13% of adults in the UK had a mobile broadband connection.

Mobile broadband not-spots

Despite the
enthusiasm with which UK net surfers have taken to mobile internet access,
coverage and performance remains an issue. The UK is not a big country and
we’ve had 3G for ten years so it would be reasonable to expect almost complete
saturation of mobile network signal, but in fact many gaps remain.

In towns and
cities you can generally rely on access to 3G, but it’s still not uncommon to
find ‘not-spots’ where the signal falls back to 2G or drops out entirely. And
once you’re out into the countryside the coverage becomes very patchy.

The network
operators claim to offer in excess of 90% coverage. In 2011 the BBC conducted a crowd-sourced experiment to explore mobile signal
throughout the UK and discovered that when a data connection was available
users were only able to get 3G around 75% of the time. The resulting map
revealed a large number of not-spots throughout the country.

That was two
years ago of course, but our own testing confirms that mobile broadband still
has a long way to go. In May we conducted our annual mobile broadband Road Trip, travelling from London to
Edinburgh while recording the performance of all major network providers.

With speed
tests, downloads and uploads and media streaming we were able to see how mobile
broadband handled practical tasks in a real situation.

Several
networks – notably Three, EE and T-Mobile – completed a large number of tests
and returned some excellent speed test results, some as high as 8Mb.

However
several networks failed to perform to a reasonable standard, with the weakest
managing to complete just 13% of the tasks. All the networks struggled with
streaming media, particularly video, none of them managing more than half of
the attempts.

This adds up
to a frustratingly inconsistent experience when using mobile internet on the
move. Provided the signal is available the connection can be incredibly fast,
particularly with the latest DC-HSDPA 3G networks providing 20Mb or more, but
all too often you’ll wander into an area with no connectivity and it will cease
to function.

The next generation

We are
hopeful this situation will improve, however, thanks to the recent introduction
of next-generation 4G mobile broadband.

The first 4G
network was launched by EE in October 2012 and is still fairly limited, but the
spectrum auction which doled out 4G frequency to the remaining providers came
with a requirement: they must commit to providing indoor coverage to 98% of the population

This should
mean that within the next couple of years we’ll see a significant improvement
in mobile broadband performance as the networks compete to offer the best
mobile internet. Not only will 4G bring much faster speeds but this caveat to
offer a minimum level of service will help reduce not-spots.

And
Britain’s Rural areas – currently poorly served by both fixed and mobile
broadband – may see the benefits too as mobile internet fills the gaps left by
our ageing telephone network.
