Cellular networks divide geography into cells to reuse radio frequencies

Bell Labs engineers designed spatial frequency reuse so millions could call simultaneously

In 1947, D.H. Ring and Richard H. Frenkiel at Bell Labs proposed dividing geographical territories into small hexagonal regions called cells. Each cell tower used low-power radio transmitters on specific frequency bands, allowing adjacent non-overlapping cells to reuse identical radio frequencies without signal interference. This architecture enabled modern mobile cellular networks.
