Wireless Communication

Wireless communication is a field within computer networking that involves the transmission of information between two or more points without the use of physical conductors like wires or cables. Instead, it relies on electromagnetic waves—such as radio waves, microwaves, or infrared—to carry signals through space, forming the basis for technologies like Wi-Fi, Bluetooth, cellular networks (4G/5G), and satellite systems. The principles of computer science are essential for managing the complexities of this medium, governing everything from data encoding and signal modulation to error correction and security protocols needed to ensure reliable and efficient data transfer over the air.
