Independent evidence for indoor mobile coverage · Offline-first architecture
The map says covered.
What happens inside?
Coverage maps indicate expected performance. MAPFIX measures actual performance. Independent data collected inside the building are compared with operators' claims.
Poor coverage costs more than a dropped call.
Tenant complaints. Guest reviews. Staff who cannot work from parts of the building. When mobile connectivity falls short indoors, businesses and building owners carry the cost, but rarely have the evidence to act on it.
MAPFIX is designed to document what connectivity is actually experienced inside your building: where, when and under what conditions. That gives you something specific to take to an operator, plan targeted improvements or include in a lease review.
No assumptions. No predictions. Just independent evidence.
Start with a building
Discuss your building.
Every building has a connectivity story operators do not tell. MAPFIX is designed to measure it, document it, and score the gap. Start with yours.
What you get
The Delta Index report.
A signed evidence report for every building. Each mobile operator scored independently against their own coverage claims, with the data behind every result.
PDF for contract negotiations and board reporting. JSON for integration with existing facilities management and audit systems. Designed to record each event with a signed timestamp and, on Android, the carrier. Precise location is discarded on the device.
Illustrative example
Operator X publishes outdoor coverage at this postcode.
Indoor measurement recorded signal below a usable threshold during part of the observation window.
The Delta Index is designed to document this gap. The scoring method is under development and will be published before use. This is not a real building or result.
Why trust it
Independent by design.
Methodology
- Methodology aligned with international recommendations on crowdsourced QoS and BEREC guidelines on QoS measurement
- Methodology review in discussion with UK universities
Independence
- No operator funding. No operator access to raw data. No conflicts of interest.
- Passive SDK: no user action required, battery target under 1% per day, designed to measure what actually happens
Architecture
- Server-side quality gates check each event before it counts
- Offline-first architecture: records coverage failures that require connectivity to report elsewhere
MAPFIX® is designed to measure 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.
Phase 1: Cellular QoS. Phase 2: Wi-Fi QoS. Phase 3: Any infrastructure SLA.
Platform
Measured coverage for every building.
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 at site level, 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
Available as a pilot engagement. 30-day passive measurement across UK mobile operators. Scope and method agreed in writing before work starts.
Based on site capacity
Pre-Deployment Assessment
Before selecting an MNO or installing IoT SIMs, MAPFIX® is designed to measure all operators on-site and compare them by observed performance.
Based on site scope
Continuous Monitoring
Ongoing passive measurement with quarterly reports. Designed to track 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. Buildings tell a different story. The delta is the product.
Delta Index (under development) · 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 Problem
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.
This scenario illustrates a design goal, not a verified event. On Android, the OS can issue a network-state callback that the SDK is designed to log with a timestamp and carrier identity. Standalone iOS does not offer equivalent background capture. Overnight evidence collection is planned from dedicated devices in managed site campaigns.
Measurement density
500 vs 50,000. Same building.
Single drive-test handset
Biased sample, user-initiated
MAPFIX®, same building
Continuous passive observation (design target). 100x density.
100:1
200-occupant building over 30 days. Each device samples ~8 times per day.
Validation
Server-side quality gates.
Every event undergoes nine validation gates before contributing to any published indicator.
- GPS accuracy: valid terrestrial H3 cell
- Temporal consistency: plausible signed device timestamp
- Signal classification: failure type matches recorded signal
- Carrier attribution: MCC/MNC matches licensed operator
- Duplicate detection
- Rate limiting: max 3 events per device per H3 cell per hour
- Device attestation: iOS DeviceCheck or Android Play Integrity (designed)
- Anomaly detection: coordinated submission patterns
- Geofence compliance for campaign events
Aligned with international QoS recommendations and BEREC guidelines on QoS measurement.

About
An infrastructure of trust.
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.
