Glossary

This section explains the terms used in this manual that are required to configure
the network.
Wireless Channel
If more than one Wireless LAN network with different ESS-ID on the same floor are communicating each
other, the baud rate may be reduced due to the same radio frequency being used. If this happens, you can
chang to different frequencies (wireless channels) for a good communication.
Note: The communication within the wireless LAN, be sure to set the same wireless channel.

DHCP Server

When configuring the network TCP/IP, be sure to set the IP address in each PC and other devices. When
there is the DHCP server on the network, you can assign IP addresses automatically to the PCs and the
AirStation on the network. If there is Windows 2000, Windows NT, dial-up router, or other device with the
built-in DHCP server function on the network, the DCHP server function may start to operate. For the Win-
dows NT server and dial-up router, or other DCHP server function, refer to the Windows 2000, Windows
NT, or dial-up router manual, or consult the manufacturer. There should be no DHCP server problems if
Windows 98/95 PCs are only on the network.
ESS-ID
This ID is used to prevent cross-communication during communication between the AirStation and PCs
within the wireless LAN. The Wireless LAN PCs that have the same ESS-ID as the AirStation can commu-
nicate with the AirStation. (ESS-ID is disabled when wireless LAN PCs are communicating each other.) Set
the AirStation ESS-ID as follows: Last six digits of MAC address + Group name. The ESS-ID is case sensi-
tive. You can enter a maximum of 32 alphanumeric characters, and the underbar "_".
LAN (Local Area Network)
Read as one word. A LAN is a network in a comparatively small area, such as a campus or within a single
building. The LAN baud rate varies from 10 Mbps to 100 Mbps.
MAC Address (Media Access Control Address)
The MAC address is a physical address specific to each network card. The MAC address is configured from
a total of six bytes as follows: A vendor code comprising the lead three bytes and a 3-byte user code. The
vendor code is managed and assigned by IEEE. The user code is managed using a unique (unduplicated)
number from the network card manufacturer. That is, the MAC address is assigned as a physical address
unique throughout the world. In an Ethernet LAN, the MAC address is used as a base to create a frame for
sending and receiving.
