6.3 IEEE802.11B (WIRELESS LAN)
6.3.1 SPECIFICATIONS
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.
Standard applied:
Data transfer rates:
Network protocols:
Bandwidth:
(divided over 14 channels, 2400 to 2497 MHz for each channel)
NOTE: The wireless LAN cannot be used together with the Ethernet. The "LAN
Type" setting in the Host Interface menu determines the LAN interface to
be used.
