A weather forecast,
but for radio waves
No on-the-ground phone testing. No operator-provided data. We simulate signal propagation from real antennas - calibrated with tens of thousands of real measurements collected in the field.
Three steps from antenna to API
- 01Data ingestion
We locate every antenna
We collect the exact position and technical characteristics of every 3G, 4G and 5G antenna from 21 official national regulators (ANFR, ANATEL, ACMA, ISED, UKE, MSIT and more) and the OpenCellID global database - over 40 million antennas indexed worldwide.
- 02Propagation model
We simulate how signal travels
From each antenna, our algorithm computes signal propagation in 3D - accounting for terrain elevation, buildings, distance and atmospheric conditions. Every square metre gets a computed signal quality score.
- 03Ground truth
We calibrate with real measurements
Tens of thousands of real-world bitrate tests, crowdsourced and lab-verified, tune our model. The result is a map that matches what users actually experience on the ground - not theoretical maximums.
Public, verifiable, auditable
We rely exclusively on official regulatory databases and open datasets - no proprietary operator feeds, no black-box signals. All 21 live countries ship a first-party antenna dataset built from official sources.

Four generations of improvements
- 2020V1
The foundations
First propagation model. Theoretical maximum bitrate per operator in 3G and 4G.
- 2022V2
5G and real-world load
Added 5G. Factored in real antenna congestion. Calibrated against field measurements.
- 2024V3
Going 3D
3D distance model accounting for building height and antenna tilt.
- 2026V4Current
Terrain matters
Full terrain-aware propagation. Substantially higher precision in hilly and urban areas.
Recognised research
Our technology is the result of years of work alongside academic research labs and public innovation funds focused on telecom and digital sciences. We partner with INRIA, France's national institute for digital science, and are supported by BPI France.
