Radio networks

Radio networks are systems that enable wireless communication by transmitting data through radio waves. They connect devices like cell phones, radios, and Wi-Fi routers to each other and to larger infrastructure such as cell towers or satellite stations. These networks facilitate voice calls, internet access, and data transfer without physical cables, using a series of interconnected antennas and transmitters. They operate across various ranges—from short-range Wi-Fi to global satellite networks—using specific frequencies to ensure clear, reliable communication over distances. Essentially, radio networks form the invisible infrastructure that supports wireless information exchange everywhere we go.
