Wireless Communication
Wireless communication uses electromagnetic waves, which are signals that travel through the air without wires, to transfer information over distances. Devices like smartphones and Wi-Fi routers send and receive these waves, allowing data like voice calls, internet access, and streaming. The data is converted into digital signals, modulated into electromagnetic waves, and transmitted. Receivers then capture these waves, demodulate them back into digital signals, enabling communication without physical connections. This technology powers most modern forms of communication, providing convenience and mobility in our daily lives.
