6.18 IEEE 802.11B (WIRELESS LAN)
6.18.1 SPECIFICATIONS
The IEEE 802.11b wireless LAN interface card is available as an option for this
machine.
A wireless LAN is a flexible data communication system used to extend or replace
a wired LAN. Wireless LAN employs radio frequency technology to transmit and
receive data over the air and minimize the need for wired connections.
•
With wireless LANs, users can access information on a network without looking
for a place to plug into the network.
•
Network managers can set up or expand networks without installing or moving
wires.
• Most wireless LANs can be integrated into existing wired networks. Once
installed, the network treats wireless nodes like any other physically wired
network component.
•
Flexibility and mobility make wireless LANs both effective extensions of and
attractive alternatives to wired networks.
