Wi-Fi Technology

Wi-Fi Technology is a wireless LAN standard, used for communication among devices on a small scale. Wi-Fi can be one of the cheapest and fastest ways for short-distance transmission, enabling regular activities like video streaming, VoIP, online gaming, and web browsing. Wi-Fi uses radio frequencies between devices. 2.4 GHz provides great coverage but slower speeds, while 5GHz has faster data rates but over a smaller area. Wi-Fi devices need to have an initial connection (often wired via DSL, cable, or fiber, or via a mobile hotspot) unless they’re part of a mesh system that works together to extend coverage. The current Wi-Fi security standard is WPA2 or WPA3.
