Wi-Fi is a technology that allows electronic devices to connect to a wireless local area network (WLAN), usually using 2.4G UHF or 5G SHF ISM RF band. Connecting to a wireless LAN is usually password-protected, but it is open, allowing any device in the WLAN to connect. Wi-Fi is a wireless network communication technology brand, owned by Wi-Fi Alliance. The aim is to improve interoperability among wireless network products based on IEEE 802.11 standards. Someone who uses the IEEE 802.11-series protocol LAN is called Wireless fidelity. Even the Wi-Fi is equivalent to the wireless internet (Wi-Fi is an important part of WLANs).
