Question

Quizplus · Accepted Answer

Cell phones use radio waves to communicate with nearby cell towers, which are essentially radio antennas placed within adjacent geographic areas. Microwaves are a type of electromagnetic radiation that are commonly used in communication technologies such as Wi-Fi but do not directly communicate with radio antennas. Satellites use radio waves to communicate with Earth stations, but this communication typically occurs over longer distances than adjacent geographic areas. WANs (Wide Area Networks) typically use cables or other physical connections rather than radio waves for communication.
