radio frequency systems

Radio frequency (RF) systems transmit and receive information using electromagnetic waves within specific frequency ranges. These systems include devices like radios, cell phones, Wi-Fi routers, and satellites, which convert data into RF signals for wireless communication. RF signals travel through the air or cables, allowing information to be shared over distances without physical connections. The systems rely on transmitters, receivers, antennas, and signal processing technology to ensure clear, reliable communication. RF systems are essential for modern connectivity, enabling everything from mobile calls to internet access and broadcasting services.
