Wi-Fi
stands for Wireless Fidelity and it can also be referred
to as a Wireless Lan (W-LAN) or an 802.11 standard.
The 802.11 standard is a family of specifications
organized by the Institute
of Electrical and Electronic Engineers (IEEE)
The specification most commonly referred to as Wi-Fi
is the 802.11b standard. This provides for nearly
11Mbps on the 2.4Ghz Band.
An even faster version of the Wi-Fi standard is the
802.11g specification. It provides for 20 or more
Mbps on the 2.4Ghz Band. Both of these standards have
a range of roughly 150-300 feet depending on landscape...
Basically enough range to enable an office or a home
to wirelessly network a few key computers and/or laptops
to eachother and the Internet.
