Mobile Coverage & Performance Mapping
We map mobile coverage and performance to the street, testing every major network at the same time — so you see exactly where signal, speed and capacity let people down.
A network can show three or four bars of signal and still fail to load a single web page — because capacity, not coverage, is what users actually feel at the busy end of the day.
In urban areas, capacity not-spots are far more common than coverage not-spots. We find both, visualise them side-by-side, and filter by time of day so you can see exactly when the network buckles.
We don’t model coverage from a desk — we drive, walk and cycle the streets, polling every network at the same time. The result is a true, like-for-like, street-level picture of what your residents, visitors and customers actually get on their phones.
Continuous polling of every operator’s signal as we survey, building a complete picture of mobile coverage across the area.
Real upload and download speeds, measured by continually transferring data with our cloud server as we move through the area.
EE, Vodafone, VMO2 and Three tested side by side from the same vehicle, on the same route, at the same time — a true like-for-like comparison.
Every individual reading is geolocated and timestamped. Zoom in to a single street, postcode or asset and see exactly what each operator delivers there.
Filter by 3-hour windows to see how networks behave at quiet times versus the rush — the moment when capacity problems actually bite.
Coverage next to capacity. Operator next to operator. The story jumps out of the maps without anyone having to read a spreadsheet.
Four direct quotes from three live UK council programmes — Westminster City Council, Manchester City Council and the Tees Valley Combined Authority (plus one of its constituent councils).
“The conversation with mobile-network operators has moved on a lot more. We know where the problem areas are. We can be constructive and collaborative about how we might be able to help them — our aim is to improve the user and visitor experience of people coming to Westminster.”
“Overall, the experience of working with the team at NetworkUX and the product delivered was exceptional in quality and delivery. I would recommend NetworkUX to any party interested in gathering data on mobile capacity.”
“Ever wondered why your apps won’t load despite full bars on your phone? That’s exactly what our new Mobile Performance Map is here to solve. It’s already highlighting where coverage is strong — and where it needs to improve — so we can work with providers to fill the gaps and make sure people get the service they pay for.”
“We’re using our bin wagons to sort more than just our rubbish — we’re sorting rubbish signal out, too. No more guesswork — this will give us hard evidence of problems people who have poor signal know only too well, and arm us to go to providers and government to get it sorted.”
NetworkUX is designed to give councils, infrastructure providers, regulators, business groups, and event teams an honest, defensible evidence base — the kind that holds up in a meeting with a network operator.
Drive, walk or cycle — or place a battery-powered NetworkUX kit in a vehicle fleet (such as waste collection) for ongoing coverage mapping. Portable kits swap between vehicles to target specific daily routes.
Hundreds of thousands of geolocated, timestamped measurements per survey, across every major network, at every point along the route.
RAG-coloured hex maps, raw datapoints and address search — with operator and time filters that make patterns immediately obvious.
Export to KML, shapefile, JSON, CSV or PDF. Take credible, granular evidence to operators and regulators — and finally have a productive conversation.
Most coverage data is built for the network. Ours is built for the people using it — which means looking in the places, and at the times, where networks actually fail.
High-footfall shopping streets, transport hubs and lunchtime hotspots where four bars on the handset can still mean a stalled web page.
Live measurement before, during and after concerts, matches, festivals and major civic events. We show exactly how the network coped — or didn’t.
Rural lanes, valleys, industrial estates and stretches of road where service simply isn’t there — surveyed across every operator at once.
Our public coverage checkers turn NetworkUX data into a clean, shareable map any resident or business can use to see how each operator performs on their street. Every map cell is a 10-metre hexagon — not the 50–100 m polygons of Ofcom and the operators — and all four UK networks render side-by-side in a single 4-up view. Real measurements only. No predictions. No crowdsourced data.
Local authorities, mobile operators, event organisers and infrastructure planners all use NetworkUX to ground their decisions in measured reality rather than predicted maps.
Evidence-led conversations with operators on coverage, congestion and service quality.
Independent like-for-like data on signal, speed and capacity across the competitive set.
Quantify how the network coped during a live event — and plan the next one better.
Validate mobile service before deploying CCTV, EV chargers, IoT sensors, digital signage and home-monitoring kit.
Phoneware Ltd (t/a Inakalum) has been developing telecoms software solutions for over 30 years. Since 2022, Inakalum has been mapping mobile coverage and performance with NetworkUX, the most comprehensive mobile network survey available. We are not aligned to any operator. We measure the network and report what we find.
The NetworkUX partner programme is launching now — for independent consultants, recently-retired professionals and small connectivity firms who want to run mobile-coverage surveys as their own business. No telecoms background needed. The platform is proven across 20+ deployments in four countries; the partner seats are open for the first time.
Book a short demo and we’ll walk you through a real NetworkUX survey — coverage, capacity, time filtering, the lot — using real data from previous mapping projects.
