Every floor,every platform,every kilometre,measured.
Buildings, factories, laboratories, metros, high-speed lines, motorways, villages: IZNAB measures mobile coverage for all four operators, from 2G to 5G. For a building, measurements follow the WiredScore specification; your report is delivered within 5 working days.
15-minute phone call or 30-minute Google Meet, Monday to Friday.
Wherever there must be signal.
The same standards everywhere: from a headquarters basement to the heart of the Channel Tunnel, all the way to the last village.
- Metros
- Every line of the Paris, Lyon, Marseille and Lille metros.
- High-speed lines
- Every high-speed (TGV) line in France.
- Motorways
- The whole French motorway network.
- Channel Tunnel
- The Eurostar link between France and England.
- Villages and rural areas
- White and grey zones, measured by drive test.
- Factories and laboratories
- Industrial sites, workshops, laboratories: wherever teams must stay reachable.
- Buildings
- Offices, headquarters, stations, hospitals, museums, up to the WiredScore label.
A building only reaches a level when its last floor does.
WiredScore judges mobile coverage point by point, then floor by floor, then across the whole building. Here is how a floor earns, or loses, its verdict.
4/5 · 80 % points in the Good zone (≥ 75% of points)
Floor verdict : Good
The walk
Our engineers walk more than 95% of each floor, along the façades and then on a second pass, stepping into every other office. Each measured point stands for 4 metres around it.
The fixed points
At least 3 static points per floor, plus one for every 400 m² beyond 800 m². At each: download and upload over 10 seconds, a call held for 15 seconds, web pages loading.
The floor verdict
When 75% of a floor's points reach a threshold, the floor reaches it. Here, 4 points out of 5 are in the Good zone: the floor is Good for this operator.
The building verdict
The building reaches a level when 100% of its floors reach it, operator by operator. A poorly covered office basement or building core is enough to bring the verdict down.
WiredScore thresholds, readable at a glance.
WiredScore rewards a service that is at least Acceptable. Our reports use exactly these thresholds and colours, floor by floor and operator by operator.

From your first call to the final report.
Before
Call and plans
A call or a video meeting to understand the building and the goal: WiredScore label, occupant complaints, operator choice. From the plans, we set the floors, zones and technologies to measure, then quote.
Day one
Measurement campaign
During working hours, as WiredScore requires. A single pass with the Keysight Nemo backpack measures all four operators at once, on the walk and at fixed points.
+5 working days
Report delivered
Coverage maps per floor and per operator, detailed and simplified summary tables, recommendations. Ready for the WiredScore file.
Reference equipment, not an app on a phone.
We measure with Keysight's Nemo Walker Air, a reference indoor measurement solution among operators and integrators. A tablet drives one device per operator along the same walk: all four networks are measured under the same conditions, at the same moment.
- 4
- operators measured in a single pass, one device each
- 1
- tablet driving every device along the walk
- 2G → 5G
- coverage, voice, throughput and web browsing
Consumer devices, as WiredScore requires: the measurement reflects what your occupants experience.
Demanding sites, measured by our teams.
Transport networks, headquarters, stations, museums, hospitals, whole cities: every site has its constraint. Some of these campaigns were carried out for integrators and operators, our clients.

Who we measure for.
- Developers and property companiesAim for the WiredScore label on a new or refurbished asset, and deliver a building with signal on every floor.
- Property and asset managers, industryPut facts behind occupant complaints, prepare a letting, compare operators, for a building, a factory or a laboratory.
- Project managers, consultants, inspection bodiesHand the mobile part of the WiredScore file to a provider who delivers in the expected format, on time.
- Operators, integrators and transport operatorsSubcontract measurement campaigns on a metro line, a rail line, a motorway or a network, in France and the European Union.
- Local authorities and project teamsDocument the white and grey zones of an area, and check coverage once the sites are built.

Frequently asked questions
When do we get the report?
Within 5 working days of the measurement day: coverage maps per floor and per operator, detailed and simplified summary tables, recommendations.
Are all four operators measured?
Yes: Orange, SFR, Bouygues Telecom and Free, in a single pass, with Keysight Nemo equipment driving one device per operator.
Do you measure 5G?
Yes. Our campaigns cover 2G, 3G, 4G and 5G, depending on the technologies your scheme or project requires.
Which floors must be measured for WiredScore?
Every floor in a building of fewer than 8 levels, one in two from 8 to 15 levels, one in three above that; the ground and first floors are always measured.
How much does an audit cost?
We quote from the plans: the price depends on the floor area, the number of floors and the technologies to measure. Send us your plans or book a call.
Do you work outside Paris?
Yes, anywhere in France and the European Union: headquarters, industrial sites, hospitals, stations, transport networks, cities.
