Wi-Fi

maker

Wi-Fi is a wireless networking protocol that enables devices to communicate over a wireless signal.

expanded

Wi-Fi operates on IEEE 802.11 standards to provide wireless connectivity for devices like smartphones, computers, and IoT devices within a local area network (LAN). It facilitates internet access through radio frequency bands, primarily 2.4 GHz and 5 GHz, making it essential for modern connectivity solutions in both home and workplace environments.

examples

A mobile device connecting to the internet via a Wi-Fi network operating on the 2.4 GHz band offering speeds up to 450 Mbps.

Commonly used in residential environments where wireless internet is needed for personal use.

A laptop connected to a corporate Wi-Fi network using the 5 GHz band for reduced interference and enhanced speed, reaching up to 1300 Mbps.

Typically utilized in enterprise settings to support high-bandwidth applications and reduce network congestion.
