What this map shows

This map displays wireless signal coverage for every populated place in Romania ( localities) and France (13,696 communes), using official regulator data.

Romania's data comes from ANCOM (Autoritatea Națională pentru Administrarea și Reglementarea în Comunicații), scraped from aisemnal.ro at 300-metre grid resolution. Each locality is matched to the nearest measurement point from ANCOM's drive-test campaigns. Coverage data spans five years: 2019, 2020, 2021, 2022, and 2024.

The picture

Of Romania's populated places: 81% have very good mobile signal from multiple operators. 608 (3.7%) have weak signal or worse. 44 (0.26%) have confirmed zero signal from all operators. Nearly 1,000 localities saw signal degrade between 2019 and 2024. Eight dropped from very good coverage to no signal in five years.

The low-signal localities concentrate along the Carpathian mountain arc, with the highest concentrations in Alba, Vâlcea, Hunedoara, Harghita, Gorj, and Caraș-Severin counties. The Apuseni Mountains are the epicentre.

Top Candidates

26 localities meet all criteria for a potential low-EMF refuge site: zero or barely usable signal, mountain or hill terrain, remote from towns, tiny or no population, and near EU Natura 2000 protected areas.

The trend

Coverage is expanding across Romania, but not everywhere. Operator withdrawal from economically unviable rural areas is creating new dead zones even as PNRR broadband deployment fills others. The result is an unstable landscape where low-EMF refuges appear and disappear unpredictably.

Why this matters

Romania's government classifies about 1,500 villages as “white zones” because they lack broadband. Our analysis shows 96% of those villages already have mobile wireless coverage. The official label hides the real exposure picture. This map shows what the wireless landscape actually looks like, based on the regulator's own measurements.

About Zone Albe

Asociația Zone Albe is a Romanian NGO working to identify, preserve, and protect low-EMF refuge zones in rural Romania. We support wired fibre-optic internet. We oppose wireless infrastructure in areas that are currently free of it. People should have the option to live without wireless radiation.
