Development of Cellular Technology
How Does Cellular Work?
The coverage area is divided into small regions called “세포,” each served by a cell tower or base station. These cells ensure efficient frequency reuse and reduce interference.
Cellular devices communicate with the nearest cell tower using radio waves. The cell tower acts as a relay, connecting the device to the broader cellular network.
As the device moves, it switches between cell towers seamlessly (handover) to maintain uninterrupted connectivity.
The cell tower connects to the core network, which routes calls, 메시지, and data between devices (or users) and external networks like the internet.
