Global Wireless Solutions’ mammoth study of wireless connectivity in UK homes combines data from extensive programme of engineering-level testing inside properties with results from nationwide poll
- 1 in 14 calls fail during in-home testing of EE’s voice network in London – only 1 in 174 test calls failed on highly reliable O2 voice network
- All of the big 4 UK operators are having difficulty extending their 4G networks into British homes
- Kitchens most liable to be mobile dead-zones and therefore best for quiet family dinners; Liverpool and Cardiff worst UK cities for blackspots in homes
- Brits living in Georgian homes and homes built in the Noughties most likely to feel blackspots are marring their indoor mobile experiences
JUNE 16, 2015 – LONDON, UK — Global Wireless Solutions (GWS), the mobile network testing company that revealed the extensive blackspots affecting UK train commuters, is today releasing the findings of its mammoth study of wireless connectivity in British homes. For its independent study, GWS polled 2,000 UK adults, and spent 6 weeks collecting and analysing data from inside London homes.
Home is where the signal isn’t: the nationwide poll
Overall, GWS’ consumer survey suggests that 40% of Brits have some kind of mobile blackspot in their home. Almost 1 in 3 respondents (32%) told pollsters they ‘regularly’ have issues making and receiving mobile calls from home; the proportion of respondents that reported regularly experiencing mobile internet connectivity issues while at home was also 30%.
The GWS survey suggests that homes built in the Georgian period are more likely to have mobile blackspots than homes from any other period of ‘modern’ British history (see Figure 1), and that Liverpool and Cardiff are the UK cities with the most home blackspot-afflicted residents (see Figure 2).
Crucially, 1 in 4 of the UK adults polled by GWS for its survey said that mobile data connectivity issues had ‘definitely contributed’ to their decision to switch operators in the past – while more than 1 in 7 respondents said that voice calling blackspots had determined their decision to ditch and switch their mobile service provider.

GWS’ engineering-level testing: EE struggles to make house calls
Over a period of 6 weeks, GWS used advanced mobile network testing rigs to gather and analyse data from inside and outside more than 50 houses in London. These rigs allowed GWS to record the ‘layer 3’ network information which most accurately reflects consumers’ mobile experiences – and which is inaccessible to companies relying on ‘crowdsourced’ testing data.
35% of the Londoners GWS surveyed for the consumer poll described above said that they had some kind of mobile blackspot in their home, and when carrying out its own testing in the capital GWS found that moving indoors had a noticeable effect on the reliability of certain UK voice networks.
1 in every 14 test calls GWS made using devices locked to the EE network failed inside houses, and EE and 3’s voice networks were the least reliable of those it tested. EE’s recent attempts to get more of its subscribers to use ‘voice-over-WiFi’ calling suggests that it may already be aware of the reliability issues revealed by GWS’ collection programme.
By way of contrast, O2’s voice network blocked less than 1% of calls during testing, while Vodafone’s blocked and dropped only 1% of calls.
Paul Carter, CEO of GWS, commented: “The UK is no longer a ‘fixed line’ nation. When we’re at home we don’t just receive calls on our mobiles – we make them too. The best phone is the one you’ve got on you – not the one sitting in its dock out in the hallway. But that presents a problem for operators – many of whom are clearly struggling with the brave new world of ‘in-home mobility’. Only by gathering and analysing accurate data on the performance of wireless networks will operators find a solution that genuinely benefits consumers – consumers who are currently not well-served by the kind of ‘crowd-sourced’ data operators too-often use to bolster unrealistic claims about the level of service they offer.”
GWS’ engineering-level testing: UK homes slam the door on 4G signal
GWS’ testing programme suggests that all of the big 4 UK operators are having problems extending their 4G/LTE networks into British homes.
3 had GWS covered with its 4G network for 78% of the time it spent testing outside properties – but only 55% of the time inside.
GWS was on 4G with EE almost 100% of the time when testing outdoors – but only 85% of the time when testing indoors.
O2 achieved the best in-home 4G penetration; GWS was on 4G with O2 for 90% of the time it spent testing inside Londoners’ homes. Vodafone was the next best performer when it came to in-home 4G access – GWS was on 4G with Vodafone for 87% of the time it spent testing inside properties.
GWS’ research suggests that the difficulties operators are experiencing (when it comes to extending 4G networks into dwellings) are having a knock-on effect on the in-home mobile data speeds Brits enjoy. GWS found that uploading the equivalent of a 2MB picture took an average of 3.9 seconds outside London homes, and 5.6 seconds inside them; similarly, uploading the equivalent of a 4MB picture took an average of 7.5 seconds outdoors and 11.3 seconds indoors. Downloading the equivalent of a 4MB song took an average of 6.4 seconds outside London homes and 7.2 seconds inside them.
EE’s mobile data network delivered the fastest average throughputs during GWS’ in-home testing programme, but the data collected by GWS suggests that the mobile data services provided by O2, Vodafone, and 3 have now also improved to the point where EE’s speed advantage is unlikely to make a difference to subscribers’ actual mobile internet experiences.
If you can’t stand the signal, get out of the kitchen
2 in 3 of the blackspot-afflicted respondents who took part in GWS’ nationwide poll said that they had a mobile calling and/or data problem in their kitchen, and the data GWS collected during its research programme supports the notion that British kitchens are especially likely to ‘play host’ to mobile blackspots.
Average operator voice reliability was at its worst in the kitchen – roughly 95% (with EE’s voice network proving less than 90% reliable). In addition, more calls failed to initialise in the kitchen than in any of the other room ‘types’ GWS tested.
In addition, GWS’ tests also found that the kitchen had both the lowest operator 4G penetration (only 74%, on average) and was the worst room for packet data reliability, suggesting that parents interested in spending some quality time with their kids should insist on holding family meals in their kitchens rather than their living or dining rooms.
Paul Carter, CEO of GWS, added:
“It is to the credit of the UK operators that British consumers are increasingly using mobile data when at home. But success comes at a price and the expectations of those consumers are now more daunting – and harder to meet – than ever before. Our data is clear: in-home mobile data blackspots drive subscribers to ditch and switch their service provider. That’s why operators need to move quickly and decisively to demonstrate the level of service they’re actually providing to Brits – with robust, understandable data that turns their in-home wireless data performance into a selling point, rather than a liability.”
Methodology and notes to editors
GWS’ nationwide poll of 2,000 mobile-phone wielding UK adults was conducted by OnePoll. Fieldwork took place from 24.2.15 to 26.2.15. OnePoll are members of ESOMAR and employ members of the MRS.
GWS tested inside and outside more than 50 homes in London from 8.4.15 to 15.5.15 using an array of 12 Samsung Galaxy S5s (powered by Rohde & Schwarz’s SwissQual QualiPoc Freerider) to gather data for its study of wireless connectivity in British homes. Four types of room were tested inside each house: a kitchen, a living room, a bedroom, and a bathroom.
Three SIMs from each of the four major UK operators (3, EE, O2 and Vodafone) were used during testing – in each case two SIMs were used for voice testing and one SIM was used for mobile data testing. An extremely wide range of voice and data metrics were analysed during the study; a specific rundown of these metrics is available on demand. The figures posted have been weighted and stat-tested.
