Wireless Communication Theory

Wireless communication theory is the study of how information is transmitted without physical connections, using radio waves, microwaves, or infrared signals. It involves understanding the principles of electromagnetic radiation, modulation (how data is encoded onto signals), and signal propagation (how signals travel through different environments). Key concepts include bandwidth (the range of frequencies used), interference (how signals can disrupt each other), and protocols (rules governing communication). This theory underpins technologies like Wi-Fi, mobile phones, and satellite communications, facilitating connectivity in our daily lives by enabling devices to share information over distances without wires.
