Wireless networks use radio waves for communication from "summary" of Data Communications and Networking by Behrouz A. Forouzan
Wireless networks operate by sending and receiving data through radio waves. These radio waves are a form of electromagnetic radiation that transmit signals wirelessly. Unlike wired networks that use physical cables to transfer data, wireless networks use radio waves to communicate between devices. This allows for greater flexibility and mobility, as devices can connect to the network without being physically tethered to a specific location. The use of radio waves for communication in wireless networks is made possible by specialized hardware components such as wireless routers and network interface cards. These devices are equipped with antennas that can send and receive radio signals, allowing them to communicate with other devices on the network. When a device wants to send data over a wireless network, it converts the data into radio signals and transmits them through the air. Oth...
