The Wi-Fi Technology

It's powerful. Wi-Fi networks use radio technologies called IEEE 802.11a ,802.11b or 802.11g to provide secure, reliable, fast wireless connectivity.

A Wi-Fi network can be used to connect computers to each other, to the Internet, and to wired networks (which use IEEE 802.3 or Ethernet).

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 or with products that contain both bands (dual band).

They can provide real-world performance similar to the basic 10BaseT wired Ethernet networks.
