Radio waves are used extensively for communication and information transmission over long distances. Their main applications include:
- Broadcasting television and radio signals (AM and FM radio)
- Mobile and fixed radio communications, including cellular telephony and wireless computer networks such as Wi-Fi
- Military communications and radar systems for detecting objects and navigation
- Satellite communications and radio navigation systems, including air-traffic control and GPS
- Shortwave radio and ham radio for long-distance communication
- Weather tracking and forecasting through radar technology
Radio waves carry data by modulating their amplitude or frequency, enabling wireless communication of audio, video, and other data essential to modern life
. They can pass freely through the Earth's atmosphere and are regulated internationally to prevent interference between different users
. In summary, radio waves are fundamental to broadcasting, telecommunications, navigation, radar, and many wireless communication technologies
