Wi-Fi (Wireless Fidelity) Fixed Wireless Access Systems and Technologies)


WiiFi generational names


Wi-Fi is a family of wireless network protocols, based on the IEEE 802.11 family of standards, which are commonly used for local area networking of devices and Internet access, allowing nearby digital devices to exchange data by radio waves. These are the most widely used computer networks in the world, used globally in home and small office networks to link desktop and laptop computers, tablet computers, smartphones, smart TVs, printers, and smart speakers together to a fixed internet access router to connect them to the Internet, and in wireless access points in public places like coffee shops, hotels, libraries and airports to provide the public Internet access for mobile devices.

Wi-Fi most commonly uses the 2.4 gigahertz (120 mm) UHF and 5 gigahertz (60 mm) SHF radio bands; these bands are subdivided into multiple channels.

Wi-Fi technology, based on the Institute of Electrical and Electronics Engineers (IEEE) wireless communication standard 802.11, has continually improved, with each generation bringing faster speeds, lower latency, and better user experiences in a multitude of environments and with a variety of device types.


Depiction of a Wi-Fi network in infrastructure mode. The device sends information wirelessly to another device, both connected to the local network, to print a document.


Access points send out beacon frames to announce the presence of networks.
