A cellular network is a system that allows mobile devices, like smartphones and tablets, to communicate wirelessly. It is made up of many small areas called cells, each served by a base station. These base stations connect to a central network, enabling users to make calls, send texts, and access the internet from almost anywhere. When you use your phone, it connects to the nearest cell tower, which then relays your data to the broader network. This setup allows for efficient communication and helps manage the traffic of many users at once, ensuring that everyone can stay connected without interruptions.
