Glossary
This section explains the glossary of terms used in this manual that are required to
configure the network.
Wireless Channel
If there is more than one Wireless LAN network with different ESS-ID on the same floor, and they are com-
municating with each other, the baud rate may be slowed, due to the same radio frequency being used. If this
happens, you can still communicate regardless of other LAN networks by using to use different frequencies
(wireless channels).
Note: If they are communications using the wireless LAN, be sure to set all the Units the same wireless
channel.
DHCP Server
When configuring the network TCP/IP, be sure to set the IP address in each personal computer and other
devices. When there is a DHCP server on the network, you can assign IP addresses automatically to the per-
sonal computers and the AirStation on the network. If there is Windows 2000, Windows NT, dial-up router,
or other device with built-in DHCP server function on the network, the DCHP server function may start to
operate. For the Windows NT server and dial-up router, or other DCHP server function, refer to the Win-
dows 2000, Windows NT, or dial-up router manual, or consult the manufacturer. There should be no DHCP
server problems for Windows 98/95 personal computers only on the network.
ESS-ID
This ID is used to prevent cross-communication during communication between the AirStation and personal
computers within the wireless LAN. The Wireless LAN personal computers that have the same ESS-ID as
the AirStation can communicate with the AirStation. (ESS-ID is disabled when wireless LAN personal com-
puters are communicating each other.) Set the AirStation ESS-ID as follows: Last six digits of MAC address
+ Group name. The ESS-ID is case sensitive. 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 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.
