What does the map show?
The main layer represents the density of registered mobile cell towers, revealing where mobile infrastructure is concentrated. It does not measure signal coverage or connection quality directly. The pattern can still indicate where networks are more developed and where infrastructure is sparse.
Why do these data matter?
📱 Mobile internet has become basic infrastructure. It affects access to work, education, payments, healthcare and information.
🌍 Infrastructure is distributed unevenly. Large cities and transport corridors generally contain dense networks, while deserts, mountains, forests and economically marginalised regions often contain fewer registered towers.
⚡ 5G supports more than faster personal connections. Its uses extend to industry, connected devices, transport systems and urban infrastructure.
🧭 Sparse infrastructure has social consequences. Limited connectivity can restrict access to services and deepen the digital divide.
Source and limitations
The mapped layer is the Global OpenCellID Cell Tower Map, a rasterised global dataset with a pixel size of approximately 1 km. It visualises the density of registered towers and should not be interpreted as a direct measurement of mobile signal, service availability or network generation. Separate and authoritative 2G, 3G, 4G and 5G coverage layers generally require operator data or specialised coverage datasets.
