Cellular describes a wireless communication system built on a grid of overlapping radio cells, each served by its own fixed transmitter. This architecture allows devices to maintain a continuous connection by handing off the signal from one base station to the next as the user moves. It fundamentally relies on frequency reuse across distant cells to support millions of users on limited radio spectrum.
