All of this can impact signal quality, and that\u2019s before we consider the differences in network (backhaul) capacity or spectrum allocations between both mast\/cell locations and operators.<\/p>\n<div class=\"bq2\"><strong>NOTE:<\/strong> Streetwave typically measures throughput speed (consumer experience), signal strength, network generation and frequency band information for all four of the main mobile network operators in the UK: <a href=\"https:\/\/www.ispreview.co.uk\/index.php\/go\/eebroadband\" rel=\"nofollow\" target=\"_blank\">EE<\/a>, <a href=\"https:\/\/www.ispreview.co.uk\/index.php\/go\/o2uk\" rel=\"nofollow\" target=\"_blank\">O2<\/a>, <a href=\"https:\/\/www.ispreview.co.uk\/index.php\/go\/threeuk\" rel=\"nofollow\" target=\"_blank\">Three UK<\/a> and <a href=\"https:\/\/www.ispreview.co.uk\/index.php\/go\/vodafoneuk\" rel=\"nofollow\" target=\"_blank\">Vodafone<\/a>.<\/div>\n<p><a href=\"https:\/\/www.ispreview.co.uk\/index.php\/link\/ofcom\" target=\"_blank\">Ofcom<\/a>&#8217;s data, which is particularly important because the government often uses it as a base for both measuring and setting related policies, is typically based on the estimates of network coverage and performance put out by the mobile operators themselves. This is generated using computer programs that simulate the way mobile signals travel from mobile masts and are blocked by any obstructions such as hills, trees, and buildings.<\/p>\n<p>Many consumers already know, from direct experience, that they should take such figures and related coverage maps (particularly those published on the operators own websites) with a sizeable pinch of salt. In addition, it doesn&#8217;t help that <a href=\"https:\/\/www.ispreview.co.uk\/index.php\/link\/ofcom\" target=\"_blank\">Ofcom<\/a>&#8217;s existing coverage predictions are processed into a &#8216;100 metre by 100 metre&#8217; grid matrix that covers the entire UK land mass.<\/p>\n<p>However, Streetwave has been busy pioneering a different approach, which is both more economically viable than other methods of practical real-world data gathering and potentially also much more accurate. The company has spent the past 18-months harnessing refuse (bin) collection trucks to map mobile network coverage and speeds across various parts of the UK (e.g. <a href=\"https:\/\/www.ispreview.co.uk\/index.php\/2024\/07\/study-finds-no-mobile-operator-in-powys-surpasses-50-for-good-coverage.html\">here<\/a>, <a href=\"https:\/\/www.ispreview.co.uk\/index.php\/2024\/07\/streetwave-maps-mobile-network-speeds-in-caerphilly-using-bin-lorries.html\">here<\/a>, <a href=\"https:\/\/www.ispreview.co.uk\/index.php\/2024\/06\/rubbish-trucks-to-help-map-4g-mobile-coverage-in-mid-wales.html\">here<\/a>, <a href=\"https:\/\/www.ispreview.co.uk\/index.php\/2024\/07\/vodafone-uk-mobile-cover-improved-in-northumberland-after-3g-closure.html\">here<\/a> and <a href=\"https:\/\/www.ispreview.co.uk\/index.php\/2024\/08\/study-reveals-state-of-mobile-network-coverage-in-ceredigion-wales.html\">here<\/a>).<\/p>\n<p>In Streetwave&#8217;s setup, refuse trucks are installed with several off-the-shelf Smartphones using special software (pictured), which run continuous network tests \u2013 once every 20 metres in rural areas and 5m in urban areas \u2013 as the vehicles go around their routes. We&#8217;ve already seen some results from this approach and a few hints (<a href=\"https:\/\/www.ispreview.co.uk\/index.php\/2025\/03\/mobile-coverage-in-worcestershire-uk-is-1000x-worse-than-ofcom-suggests.html\">here<\/a>) that the data may call into question Ofcom&#8217;s own figures, which, given the different methodologies, is not surprising.<\/p>\n<h3><span style=\"color: #339966;\"><strong>Streetwave&#8217;s Findings<\/strong><\/span><\/h3>\n<p>The big change today is that Streetwave believes it has now amassed enough data to show that Ofcom&#8217;s figures may be quite far off the reality. The company has so far mapped 113 councils across the UK, collecting over 40 million data points. These represent around 37% of the UK\u2019s geography and have around 19 million people living and working in them. The results collected so far are said to show the following &#8220;<em>Acceptable Coverage<\/em>&#8221; levels from each of the four major mobile network operators (MNOs), with <a href=\"https:\/\/www.ispreview.co.uk\/index.php\/go\/eebroadband\" rel=\"nofollow\" target=\"_blank\">EE<\/a> doing the best and <a href=\"https:\/\/www.ispreview.co.uk\/index.php\/go\/threeuk\" rel=\"nofollow\" target=\"_blank\">Three UK<\/a> the worst.<\/p>\n<div class=\"bq2\"><strong>NOTE:<\/strong> Streetwave defines Acceptable Coverage as being a network that can provide users with 5Mbps download, 2Mbps upload, and below 40ms latency times. &#8220;<em>These are speeds where most mobile use cases including internet browsing, video streaming or conference calls can be performed<\/em>,&#8221; said the company.<\/div>\n<blockquote><p><span style=\"color: #339966;\"><strong>Acceptable Coverage by UK Mobile Operator<\/strong><\/span><br \/>\n\u2022 <a href=\"https:\/\/www.ispreview.co.uk\/index.php\/go\/eebroadband\" rel=\"nofollow\" target=\"_blank\">EE<\/a> \u2013 69%<br \/>\n\u2022 <a href=\"https:\/\/www.ispreview.co.uk\/index.php\/go\/vodafoneuk\" rel=\"nofollow\" target=\"_blank\">Vodafone<\/a> \u2013 61%<br \/>\n\u2022 <a href=\"https:\/\/www.ispreview.co.uk\/index.php\/go\/o2uk\" rel=\"nofollow\" target=\"_blank\">O2<\/a> \u2013 50%<br \/>\n\u2022 <a href=\"https:\/\/www.ispreview.co.uk\/index.php\/go\/threeuk\" rel=\"nofollow\" target=\"_blank\">Three UK<\/a> \u2013 38%<\/p><\/blockquote>\n<blockquote class=\"bq1\"><p><strong>Angus Hay, Streetwave\u2019s CEO, said:<\/strong><\/p>\n<p>\u201cA collaborative approach is needed to improve mobile connectivity across the UK. This includes continued private and public investment into the networks, as well as local efforts by councils and planning authorities to support infrastructure investments. Our findings raise significant questions around whether there is need for an extension to the Shared Rural Network programme to further support rural communities.\u201d<\/p><\/blockquote>\n<p>However, there are some caveats to consider, as Streetwave&#8217;s comparison with Ofcom&#8217;s figure is not an apples-to-apples one. Firstly, Ofcom&#8217;s data covers the whole of the UK, while Streetwave still has a lot of area left to cover and that may yet influence their overall result. The fact that a lot of the geography they&#8217;ve reached is in rural Scotland and Wales may be a key factor here that could throw the overall balance off. Time will tell.<\/p>\n<p>The other crucial factor to consider stems from how this is NOT an identical measurement criteria to Ofcom&#8217;s 88-89% landmass range for <a href=\"https:\/\/www.ispreview.co.uk\/index.php\/link\/4g\">4G<\/a>, which is the one that Streetwave calls out in their announcement &#8211; this could risk causing some confusion (major newspapers are notorious for overlooking details like this).<\/p>\n<p>For 2G, <a href=\"https:\/\/www.ispreview.co.uk\/index.php\/link\/3g\">3G<\/a> and 4G networks, <a href=\"https:\/\/www.ofcom.org.uk\/siteassets\/resources\/documents\/research-and-data\/multi-sector\/infrastructure-research\/connected-nations-2024\/connected-nations-2024-annex.pdf?v=386498\" target=\"_blank\" rel=\"noopener\">Ofcom define coverage<\/a> based on the minimum signal strength required to at a minimum deliver a 98% probability of making a 90-second voice call successfully. In the case of 4G specifically, Ofcom&#8217;s definition also delivers a 95% chance of getting a download speed of at least 2Mbps. This is fairly different from Streetwave&#8217;s definition of &#8220;<em>Acceptable Coverage<\/em>&#8221; above. You could argue that Streetwave&#8217;s definition is better, but it is not the same.<\/p>\n<p>Ofcom are already well aware of the shortcomings in their data and are working to improve it (<a href=\"https:\/\/www.ispreview.co.uk\/index.php\/2025\/03\/ofcom-to-launch-improved-uk-mobile-coverage-checker-later-in-2025.html\">here<\/a>). For example, they plan to improve their own coverage checker by adopting higher signal strength thresholds when presenting local predictions, while also assessing predicted signal strength information at a more granular level (50 or 25 square metres, instead of the current 100 square metres) to determine if it is possible to reduce the local uncertainty to some extent.<\/p>\n<p>The regulator is also examining the use of measured data, including crowdsource data, to build on these coverage predictions (this may or may not include Streetwave&#8217;s data). Finally, once the regulator&#8217;s new coverage checker has launched later in 2025, Ofcom will move to consider undertaking a larger scale performance measurement programme to complement coverage predictions and enhance their mobile reporting.<\/p>\n<blockquote class=\"bq1\"><p><strong>A spokesperson for Ofcom recently told ISPreview:<\/strong><\/p>\n<p>\u201cOur current coverage data comes from mobile network operators\u2019 predictions, which we recognise may not always match people\u2019s real-world experience at a very local level. We are working hard to overhaul our mobile coverage checker, which we expect to relaunch later this year with new and improved data to better reflect what people can expect.\u201d<\/p><\/blockquote>\n<p><strong>UPDATE 12:16pm<\/strong><\/p>\n<p>We&#8217;ve had a reaction from Mobile UK, which represents the mobile operators.<\/p>\n<blockquote class=\"bq1\"><p><strong>Mobile UK Statement<\/strong><\/p>\n<p>&#8220;Mobile UK disputes the findings presented by Streetwave. While we acknowledge that all models, including our own, involve predictive elements, Streetwave&#8217;s conclusions are based on an extremely limited dataset, derived from just a third of councils across four nations, and are heavily skewed towards rural, low-population density areas. This significantly restricts its applicability to the broader UK mobile landscape.<\/p>\n<p>While we do not agree with these findings it once again puts in sharp focus the need for the Government to better prioritise mobile deployment in its policy making. We look to the upcoming infrastructure strategy as a crucial opportunity to translate this focus into tangible action. Mobile UK&#8217;s key asks remain consistent: streamlining planning regulations to expedite network deployment, ensuring equitable access to public land and assets, and fostering investment in digital infrastructure to close the digital divide. We are confident that by addressing these critical areas, the government can create a policy environment that empowers the mobile industry to deliver the world-class connectivity that the UK deserves.&#8221;<\/p><\/blockquote>\n","protected":false},"excerpt":{"rendered":"<p>Network analyst firm Streetwave, which is harnessing bin lorries to map the coverage and performance of 4G and 5G mobile (broadband) networks across 113 UK councils, has said its data &#8220;calls into question&#8221; Ofcom&#8217;s claim that 88-89% of the UK&#8217;s landmass (geographic coverage) can access a 4G network if you look across all operators.<\/p>\n","protected":false},"author":1,"featured_media":41382,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"ngg_post_thumbnail":0,"footnotes":""},"categories":[1],"tags":[61,406,405,60,32,36,38,34,63,96],"class_list":["post-41380","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-uk_isp_news","tag-4g","tag-5g","tag-ee","tag-mobile-broadband","tag-o2","tag-ofcom-regulation","tag-politics","tag-statistics","tag-three-uk","tag-vodafone"],"share_on_mastodon":{"url":"https:\/\/mastodon.social\/@ispreview\/114267233752228066","error":""},"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.2 -
