What is wireless communication?

Wireless communication refers to the transfer of information between two or more points that are not connected by an electrical conductor. This technology uses electromagnetic waves, such as radio frequencies, infrared, or satellite signals, to transmit data over distances ranging from a few meters (like Bluetooth) to thousands of kilometers (like satellite communication). Wireless communication is widely used in devices like mobile phones, Wi-Fi networks, and GPS systems. Its convenience and flexibility have made it an essential part of modern communication infrastructure.
