What kind of portable radio communicates through interconnected series of repeater stations called "cells"?

A cellular telephone is specifically designed to communicate through a network of interconnected repeater stations known as cells. This structure allows for efficient and extensive coverage, as each cell is served by its own antenna and transmitter, enabling seamless communication across a broader geographic area. When a user makes a call, the signal is transmitted to the nearest cell tower, which then relays the call through the network to the intended recipient, potentially connecting through multiple cells as the user moves.

The cellular system is distinct from other forms of communication like walkie-talkies, which operate on a direct radio frequency without the use of a repeater network. Landline phones rely on physical wiring and do not use radio signals at all, while satellite phones communicate with satellites orbiting the Earth, bypassing the terrestrial cell networks entirely. Each of these alternatives has its own specific use cases, but the defining feature of the cellular telephone's operation is its reliance on a network of cells to maintain connectivity.
