Radio

A technology that uses electromagnetic waves to transmit information, such as sound, over long distances without wires. Primarily, it encompasses both the process of broadcasting and receiving these signals, but is also used to describe the electronic devices that perform these functions. It has been a pivotal medium for entertainment, news, and communication, evolving from early wireless telegraphy to modern applications like cellular networks and satellite broadcasting. It fundamentally relies on radio waves for wireless signal transmission. Beyond entertainment, it encompasses essential emergency services and navigation systems.
