How WIFI works WiFi is a technology that allows you to use the Internet on your handheld device, even without a wired connection. WiFi connects our mobile or other devices wirelessly or over the air with a router or internet. IEEE or Institute of Electrical and Electronics Engineers defines WIFI standards under the family of 802 network specifications. here – 802.3 is used for Ethernet 802.15 is used for Bluetooth 802.11 is used for WIFI networking standards
