Predicted ≠ measured
Operator coverage maps are predictive models, not measurements. They reflect what should work, not what does. At street and asset level, the gap between the two can be the difference between a working sensor and a silent one.
For Smart Infrastructure
A connected device

is only as good as its signal.
For IoT solution providers, smart-city programmes, utility deployments, fleet and logistics telematics, parking and mobility operators, system integrators and connected-asset operators — NetworkUX validates mobile coverage and performance at every candidate site before the hardware ships.

The silent failure mode

Connected infrastructure projects are built on an assumption that the mobile network will be there when needed. When it isn’t, the failure is silent — a sensor stops reporting, a tracker drops out, a payment terminal can’t authorise — and you find out from a customer complaint, not your dashboard.
NetworkUX surveys every candidate site, every operator, before the asset is committed — so the connectivity assumptions in the business case are validated against actual measurements rather than published coverage maps.

Three ways we de-risk a rollout
Validate. Choose. Monitor.
From the first candidate-site list through to the last commissioned asset, NetworkUX is the connectivity-validation layer between your deployment plan and the network it depends on.
01
Pre-deployment site validation
Survey every candidate location across every UK network before you ship the hardware. Address- and asset-level lookups identify the sites where connectivity is marginal — before commissioning, not after a customer flags it. Every lookup returns the 10-metre hexagon the asset sits in, not a 50–100 m polygon that lumps it together with its neighbours.
02
Network & SIM selection
Some networks work, others don’t. NetworkUX shows you which operator delivers at each site — so you can specify the right SIM per location, or justify the cost of a roaming SIM with data instead of intuition.
03
In-life estate monitoring
Survey existing deployments at intervals to flag connectivity decay before it becomes a reliability problem. Repeat surveys make trends visible — particularly important in urban areas where capacity changes over time.
In their words
What council customers say after the data lands on the table.
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.”
Head of Smart City, Westminster City Council
“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.”
Senior Digital Strategy Officer, Manchester City Council
“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.”
Tees Valley Mayor
“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.”
Leader, Darlington Borough Council
How it works
Three ways to plug NetworkUX into your deployment programme.
Priced and scoped per site or per programme — light enough to use on a 50-asset pilot, structured enough to underpin a 10,000-asset rollout.
-
Site-list survey
Send us your candidate-site list with addresses or coordinates. We survey each one and return a report per site — coverage and performance, by operator, by time of day.
-
Area survey
For programmes where site locations aren’t fixed yet, survey the whole target area and use the data to choose deployment locations. Find the green zones, avoid the red.
-
Estate audit
For deployed estates, survey at 6- or 12-month intervals. Find the assets whose connectivity has degraded before reliability metrics drop.
-
API & data feeds
Export to KML, shapefile, JSON, CSV for ingestion into your asset management, GIS or commissioning systems. Raw datapoints, not just maps.
Where this gets used
Every asset that needs a SIM is a candidate.
The unifying need is the same across asset types — will the network work here, on the operator I’m planning to use? A few of the categories we work with.
Environmental & air quality
Sensor networks for air quality, weather, flood and noise monitoring — usually deployed at scale across a city or region.
Smart streetlights
Connected luminaires for adaptive lighting and asset reporting. Mobile connectivity is the path the data goes home.
Smart bins & waste
Fill-level sensors and dynamic collection routing. Silent failures here mean missed collections and complaints.
Connected traffic & footfall
Roadside cameras, vehicle counters, footfall sensors — the inputs to urban traffic and high-street analytics.
Smart parking
Bay-level occupancy sensors, payment terminals, ANPR cameras — each one a connected asset that needs to authenticate transactions.
Fleet & logistics telematics
Vehicle trackers, in-cab telematics, asset tags — performance falls off badly in known coverage holes along delivery routes.
Smart utilities & metering
Smart electricity, gas and water meters; connected substations and grid sensors. Long-life deployments where the connectivity decision is locked in for years.
Digital signage & kiosks
SIM-fed signage and self-service kiosks rely on data to refresh content and report status. Survey before specifying.
Connected agriculture
Soil, livestock, machinery sensors in rural areas — where coverage from any operator can be marginal and choosing the right network matters most.
System integrators
For SIs delivering smart-city or industrial-IoT projects, NetworkUX is the connectivity due diligence step that protects the prime contract.
Why an independent survey
Operator maps don’t tell you what your devices will see.
Three reasons internal connectivity validation usually falls short — and why an independent, multi-operator survey is the answer.
Your SIM only knows one network
An EE SIM can’t tell you what Vodafone, VMO2 or Three would do at the same spot. NetworkUX measures all four simultaneously so the SIM decision is informed by data, not default.
4 bars doesn’t mean throughput
A site with great signal can still fail when devices need to send data at busy times. NetworkUX measures both, so you know whether the network has the capacity for what your assets are trying to do.
Talk to our smart-infrastructure team
Show us your candidate-site list. We’ll show you what to deploy where.
Send across the site list for your next rollout — whether that’s 50 sensors, 500 parking bays or 5,000 meters. We’ll scope a NetworkUX survey, validate every site across every network and send back a report your commissioning team can act on.
