What does Wireless Local Area Network (WLAN) primarily utilize for communication?

Wireless Local Area Networks (WLAN) primarily utilize high-frequency radio waves for communication, allowing devices to connect to the network without the need for physical cables. This technology enables users to access the internet and transfer data wirelessly over short ranges, typically within the confines of a building or campus.

Radio waves are a form of electromagnetic radiation that can travel through the air, making them ideal for wireless communication. WLANs typically operate using standards defined by the IEEE 802.11 protocol, which encompasses various technologies (like Wi-Fi) that operate on different frequency bands, usually 2.4 GHz and 5 GHz.

This wireless capability not only promotes mobility and convenience by connecting devices such as laptops, smartphones, and tablets seamlessly but also facilitates easy setup and expansion of network connectivity without the constraints of physical wiring.
