6.13.1 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:
IEEE802.11b
Data transfer rates:
11 Mbps/5.5 Mbps/2 Mbps/1 Mbps (auto sense)
Network protocols:
TCP/IP, Apple Talk, NetBEUI, IPX/SPX
Bandwidth:
2.4GHz
(divided over 14 channels, 2400 to 2497 MHz for each
channel)
NOTE:
The wireless LAN cannot be active at the same time as the Ethernet. The
“LAN Type” setting in the Host Interface menu determines which LAN
interface will be used.
