Ambition North Wales, which is a partnership comprising the six Local Authorities in the region and several Universities, has worked with UK consultancy firm FarrPoint to conduct a survey that measured 4G mobile (mobile broadband) coverage across the region’s main transport routes. Suffice to say, there are some problem areas.
The survey follows a 2021 consultation with regional industry representatives, who stated that inconsistent 4G connectivity on transport networks is affecting economic activity in the region, including tourism and transport operations. In response, Ambition North Wales undertook a project with FarrPoint that attempted to measure 4G connectivity along the region’s A and B roads, as well as its rail network.
We should point out that this work used Ofcom’s stated threshold for delivering a “good quality of experience to consumers” on the 4G network. This is the signal strength required to, at a “minimum“, deliver a 98% probability of making a 90-second telephone call successfully. In the case of 4G specifically, the definition also includes a 95% chance of getting a download speed of at least 2Mbps.
Admittedly, we find ourselves wishing that they could supply these results as a visualised map (something FarrPoint are usually good at), but for the time being the limited results above will have to suffice. The findings will provide valuable evidence for Ambition North Wales to consider which areas require Growth Deal funding for any future improvements to digital connectivity.
Stuart Whitfield, Digital Programme Manager for Ambition North Wales, said:
“The results from the mobile survey will help us make informed decisions on where to direct investment for improving mobile connectivity within our region. It is important that decisions are supported with strong independent evidence of need, allowing us to see which areas lack coverage.
Whilst 4G coverage is relatively good in some parts of North Wales, elsewhere it remains an issue for residents, businesses and visitors to the region. Along with the UK government’s wider Shared Rural Network project, Ambition North Wales aims to improve mobile coverage on our transport networks as a priority through the Growth Deal.”
The alternative to this would often be to use carrier data and predicted modelling, which has a tendency to be over-optimistic about signal quality and can be inaccurate. One other option they could have used is to look at crowdsourced data from the likes of nPerf and Opensignal, but this is subject to a variety of other caveats.
