Wi-Fi – Wireless Fidelity
Wi-Fi is a trademark of the Wi-Fi Alliance, a nonprofit industry association. Wi-Fi allows wireless connection for computers to send and receive data within the range of a base station.
Wi-Fi networks use radio technologies called IEEE 802.11b or 802.11a to provide secure, reliable and fast wireless connectivity. A Wi-Fi network can be used to connect computers to each other, to the Internet and to wired networks.
Wi-Fi networks operate in the unlicensed 2.4 and 5 GHz radio bands, with an 11 Mbps (802.11b) or 54 Mbps (802.11a) data rate.
