Radio wavelength doesn't work like that.
Radio is (1) regional (thus "cell phone"), (2) directional (thus "beam antenna" to simplify the field greatly).
(1) and (2) mean the serviced space is divided into cells, and the cell shape and size are designed, eccording to physical and economic concerns. For example, long, thin cells are used along major roads. Where there is a higher population density, smaller cells are used.
