What technology does Wi-Fi primarily use for connectivity?

Wi-Fi primarily utilizes radio waves for connectivity. This wireless technology operates within specific frequency bands, typically using the 2.4 GHz and 5 GHz ranges, to transmit data between devices, such as laptops, smartphones, and routers. Radio waves are well-suited for this purpose due to their ability to propagate through various materials, allowing signals to travel over considerable distances and penetrate walls.

This makes Wi-Fi a convenient choice for creating local area networks (LANs) in homes, offices, and public spaces. While infrared signals and microwave frequencies are also types of electromagnetic waves, they are not the primary technology for Wi-Fi connectivity. Infrared signals are used in applications like remote controls, and microwave frequencies are prevalent in radar and certain communication technologies but not specifically for Wi-Fi. Satellite signals pertain to long-range communication over large distances and are typically used for satellite internet or telecommunications rather than short-range networking.
