We locate every antenna
We collect the exact position and technical characteristics of every 3G, 4G and 5G antenna from 21 official national regulators (ACMA, RTR, BIPT, ANATEL, ISED, SUBTEL and more).
A propagation model, calibrated in the field
Sogudo computes how the mobile signal spreads from every declared antenna, then corrects the model with measurements taken on the ground. The result compares carriers independently at any point of a territory.
Three steps from antenna to API
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.
We calibrate with field data
Real-world speed measurements are compared with what the model predicts at the same spot, and the gaps are used to correct it. The calibrated model then gives every carrier a comparable value at any point of the country.
Official antenna registers
Antenna positions come from the registers that national regulators make public. No carrier feeds the model. Each of the 21 live countries has its own antenna dataset built from these official sources.

GEDTM30 v1.2 — Global Ensemble Digital Terrain Model, 30 m
Terrain comes from GEDTM30, a global 30 m digital terrain model built by OpenGeoHub from the Copernicus WorldDEM-30 (European Union and ESA, from the DLR/Airbus TanDEM-X mission) and the Japanese AW3D30 (JAXA), corrected with ICESat-2 and GEDI laser altimetry. For every antenna we compute which ground cells are in line of sight: a hill or a ridge between you and the antenna removes the coverage behind it, instead of drawing a full circle.

GHS-SMOD R2023A (Global Human Settlement Layer, degree of urbanisation), epoch 2025, 1 km
The GHS-SMOD settlement grid of the European Commission's Joint Research Centre classifies every square kilometre as dense urban, urban or rural. The propagation model uses that class around each antenna: the same transmitter reaches much farther in open country than between buildings.

BD ALTI® 25 m
Terrain comes from IGN's BD ALTI® 25 m digital terrain model (sea and foreign areas filled with GEDTM30). For every antenna we compute which ground cells are in line of sight: a hill or a ridge between you and the antenna removes the coverage behind it, instead of drawing a full circle.

An algorithm that keeps improving
Each factor below enters the model as soon as a country publishes the data for it, so precision improves country by country.
Antenna characteristics
Height, azimuth, tilt and frequency band of each antenna. Regulators do not all publish the same fields, and the model uses every one that exists in a given country.
Terrain
Elevation models show where hills and valleys block or reflect the signal.
Buildings and land cover
Building height, forests and open ground change how far a signal carries. They enter the model country by country as the data becomes available.
Network load
Where load data exists, the model reflects the speed shared between users and not only the signal level.
- Growing every day
Measurements from our users
Every speed test run by a Sogudo user is compared with the model. The more tests come in, the more precise the next calculation gets.
Recognised research
Our propagation model was validated with Inria, the French national research institute for digital science, and Sogudo is supported by Bpifrance.
