What is a Wireless LAN?
A local area network that transmits over the air typically
o
in an unlicensed frequency such as the 2.4GHz band.
A wireless LAN does not require lining up devices for line of
sight transmission like IrDA. Wireless access points (base
stations) are connected to an Ethernet hub or server and
transmit a radio frequency over an area of several hundred
to a thousand feet which can penetrate walls and other
non-metal barriers. Roaming users can be handed off from
one access point to another like a cellular phone system.
Laptops use wireless network cards that plug into an existing
PCMCIA slot or that are self contained on PC cards, while
stand-alone desktops and servers use plug-in cards (ISA,
PCI, etc.).
•
What is AD-HOC?
An AD-HOC network is a peer to peer network where all
o
the nodes are wireless clients. As an example, two PC's
with wireless adapters can communicate with each other
as long as they are within range. A wireless extension
point can extend the range of an AD-HOC network.

What is the 802.11 standard?
A family of IEEE standards for wireless LANs first introduced
