Cellular technology refers to the use of a network of radio towers to provide wireless communication over a wide area. These towers, known as cell sites, divide regions into smaller areas called cells, allowing multiple users to connect simultaneously without interference. This technology enables mobile devices, such as smartphones and tablets, to send and receive data, make calls, and access the internet. The development of cellular technology has evolved through several generations, from 1G for basic voice calls to 5G, which offers high-speed data and low latency. Each generation introduces improvements in speed, capacity, and connectivity, enhancing the overall user experience and enabling new applications like IoT (Internet of Things) devices.
