Coverage maps predict. Your buildings tell the truth.
MAPFIX® independently verifies in-building mobile connectivity, compares it with operator claims, and scores the gap. Evidence from real devices, in real rooms, across every network.
standard compensation mechanism for coverage failure
How it works
Measure. Compare. Score.
STEP 01
Measure
A lightweight SDK on occupant devices passively records signal strength, carrier identity, and connection state. No speed tests. No user action. Under 1% battery impact.
STEP 02
Compare
Measured reality is compared against each operator's published coverage claims for that location. The gap between promise and experience is calculated per operator, per floor.
STEP 03
Score
The Delta Index scores every building from A (coverage matches claims) to F (significant shortfall). Auditable, timestamped, exportable as PDF and JSON.
What you get
The Delta Index report.
A signed evidence report for every building. Each mobile operator scored independently, floor by floor, against their own coverage claims. Letter grades from A to F, with the raw data behind every score.
PDF for contract negotiations and board reporting. JSON for integration with existing facilities management and audit systems. Every measurement timestamped, carrier-attributed, and anonymised.

Who this is for
Buildings. Regulators. Operators who want the truth.
Building owners and operators
Hotels, hospitals, universities, commercial property. Independent evidence of what mobile coverage your occupants actually receive, formatted for SLA negotiations and contract renewals.
National telecom regulators
Independent QoS evidence sourced from citizens, not operators. Aligned to ITU-T E.812 and the BEREC Crowdsourced QoS Framework. PDF and JSON formatted for enforcement and licensing review.
Operators ready to differentiate
The first operator to publish verified Delta Index scores signals confidence in its own network. In a market where every competitor claims the same coverage, measured proof is a competitive advantage.

Independent by design.
Methodology
Methodology aligned with ITU-T E.812, the international standard for crowdsourced QoS assessment
Under academic validation at Middlesex University London
Independence
No operator funding. No operator access to raw data. No conflicts of interest.
Passive SDK: no user action required, under 1% battery impact, measures what actually happens
Architecture
Nine-gate automated validation pipeline: every measurement verified before it counts
Offline-first architecture: records coverage failures that require connectivity to report elsewhere
MAPFIX® measures what occupants experience. WiredScore certifies what landlords build. Complementary, not competitive.
Future vision
From evidence to certification.
Every building has an energy rating. None has a mobile connectivity rating. MAPFIX® is designed to create the missing standard.

Mobile QoSWhat occupants receiveMAPFIX® is building this
MAPFIX® is designed to provide objective data to help organisations evaluate mobile network performance. Concrete evidence to verify SLA adherence and negotiate improved contracts.
Built for your sector
Six industries. One measurement layer.
Hotels & Accommodation
A connectivity gap costs bookings on Booking.com. MAPFIX® is designed to record coverage floor by floor, giving asset managers evidence to work with operators.
Hospitals & Healthcare
Connectivity failures in clinical settings pose serious operational risks. MAPFIX® is designed to transform dead zones into timestamped, auditable records.
Commercial Property
Smart building technology and lease agreements need independent network validation. MAPFIX® is designed to evaluate all local mobile networks before occupancy.
Universities
Students depend on campus connectivity for safety and engagement. MAPFIX® is designed to provide building-specific network quality insights for estates managers.
Financial Institutions
Banks rely on connectivity for POS terminals, mobile banking, and real-time fraud detection. MAPFIX® is designed to provide branch-specific passive measurement data.
Government & Public Sector
Evidence-based procurement for public services. MAPFIX® is designed to provide independent, auditable QoS evidence across all government sites.
Packages
Evidence, formatted for your contract renewal.
Site Delta Audit
30-day passive measurement across all four UK mobile operators. Signed PDF evidence report with building grades, Delta comparison, and JSON export.
Based on site capacity
Pre-Deployment Assessment
Before selecting an MNO or installing IoT SIMs, MAPFIX® tests all operators on-site and ranks them by measured performance.
Based on site scope
Continuous Monitoring
Ongoing passive measurement with quarterly reports and real-time degradation alerts. Tracks whether your MNO maintains the SLA.
Based on site capacity
Multi-Site Portfolio
Centralised dashboard ranking all sites by network quality. For estates teams managing hotel chains, hospital trusts, or university estates.

Evidence map
Every ping. Every region. Real geography.
Operators claim coverage. Citizens report failure. The delta is the product. 170 countries. 500+ licensed operators.
170 countries · 500+ operators · Delta Index · PDF report generation · Operator and regulator views
All figures are illustrative sample data. Live engagements produce jurisdiction-specific calculations under signed agreement.
Technology
Offline-first evidence architecture.
A citizen in a dead zone cannot report being in a dead zone, because reporting requires the connectivity that is absent. Every speed test, every crowdsourced platform, every operator tool depends on an active connection. Without it, no measurement occurs. The dead zone is invisible.
MAPFIX® is designed to solve this. Offline-first by architecture.
The 3 AM Proof
You are asleep. Your network drops. MAPFIX® records it.
At 3:00 a.m., your phone rests on the nightstand. Your operator's network disconnects. At 5:12 a.m., it reconnects. You wake at 7:00 and never know.
But MAPFIX® recorded it.
Timestamped. Carrier-attributed. Anonymised. No drive test was active. No speed test was running. No one was awake. The evidence exists because the operating system issued a callback, logged by the SDK. This is verified nocturnal outage documentation. No other methodology can produce it.
Measurement density
500 vs 50,000. Same building.
~500
active measurements per month Single drive-test handset Biased sample, user-initiated
~50,000

Investment in early-stage companies involves significant risk. SEIS relief depends on individual circumstances. This is not a financial promotion.
Comparable exit
WiredScore acquired for ~$1 billion.
In March 2026, Meter acquired WiredScore, which certifies broadband infrastructure landlords build. MAPFIX® measures what the operator delivers through that infrastructure. The market for building connectivity verification is valued in the billions. MAPFIX® is designed to occupy the complementary position WiredScore does not cover.
For regulators
Independent QoS evidence you can act on.
MAPFIX® is designed to provide national telecommunications authorities with an independent corroborating infrastructure layer. Auditable evidence aligned to ITU-T E.812 and the BEREC Crowdsourced QoS Framework, at sub-kilometre resolution.
Independent QoS evidence sourced from citizens, not operators
Formatted PDF evidence summary for enforcement and licensing
Machine-readable JSON for integration with existing audit systems
MAPFIX® is not a speed test. It is not a consumer complaint app. It is being built as the independent corroborating layer designed to document the gap between what mobile operators claim and what citizens experience, offline-first, in the places where other tools cannot operate.
The founder
Why I built MAPFIX®
I spent several years working in hospitality, where a single bad review can damage a brand permanently. When a guest had a poor experience, we offered an extra night or a 20 to 40 per cent refund, because protecting the brand was worth more than winning the argument.
Then I would leave work, get on a train, and spend an hour commuting with no mobile signal. At the end of the month, the bill arrived in full. No apology. No adjustment.
In Cameroon, where I grew up, the situation is worse. The gap between what operators claim and what people actually receive is wider, and the tools to prove it do not exist.
I am British and Cameroonian. That is not a biographical detail. It is the reason MAPFIX® will succeed where Western platforms have failed. I do not need a cultural liaison to speak to ART Cameroon. I do not need a translator in Douala. I grew up in the connectivity gap. I am building the evidence from inside it.
That contrast, between an industry that compensates every failure and an industry that ignores them, is where MAPFIX® came from.
