Multiple AirStation Groups
When multiple AirStations are used to communicate with the wireless LAN personal computers on the same
floor, the baud rate may be reduced. This is because the AirStations are using the same frequency to communicate simultaneously. If this happens, you can enable communications regardless of other LAN networks
by making settings to use different frequencies (wireless channels) in each LAN network (i.e., grouping).
Change the wireless channels and group the networks is done using the following procedure.

Glossary
6
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 communicating 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 personal 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 Windows 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 computers 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.
WLA-L11 User’s Manual58

TCP/IP(Transmission Control Protocol/Internet Protocol)
TCP/IP is a protocol equivalent to the network and transport levels of the OSI reference model, and it is
defined using RFC. Consequently, different terminals can communicate with each other using TCP/IP.
• Normally, TCP/IP includes the application protocols TELNET and FTP.
• TCP/IP is the standard internet protocol.
WEP (Encryption)
By setting an encryption key in the AirStation, you can prevent wireless packets from being decrypted externally. When connecting to the AirStation with the encryption key you must enter the encryption key from
the client manager.

Firmware
Firmware is the name given to the software (programs) built into hardware such as the router, modem, and
terminal adapter. This software is built into the hardware, so it can be said to be in-between hardware and
software.
Protocol
Protocols are the procedures and regulations for sending and receiving data between the network terminals.
For example, if two computers are communicating, you can send the correct information according to the
regulations by formatting all required information. The protocol such as which terminal sends first, what
type of message, what type of message the receiving terminal should send in reply, the data format, and
responses to communications errors are same of examples.
