Rapid, reliable communication over long distances
Wireless communication technologies, such as Wi-Fi, Bluetooth, and cellular networks, allow for communication over long distances without the need for physical cables. These technologies use electromagnetic waves to transmit data through the air, enabling devices to connect and communicate with each other seamlessly.

Telegraph wires were strung across the continent to bring communication to people from far distances before the invention of telephone or internet. These wires allowed messages to be transmitted quickly and efficiently over long distances, revolutionizing communication in the 19th century.
Radio waves typically have long wavelengths ranging from several millimeters to several meters. Their long wavelengths enable them to travel long distances and penetrate obstacles such as buildings, making them useful for communication over long distances.
The earliest advance in technology that enabled communication over long distances was the telegraph. Then there was the telephone later on.
The History of the Telegraph. Since the early days of long distance communication, the technology we use has come a very popular.
Well, you don't NEED them, but they are pretty convenient to talk to people over long distances wherever you are.
