12. Glossary

Access point
Device used for relaying transmissions when using the "Access Point".
Can be used for relaying transmissions between wireless LAN devices and wired LAN devices as
well as relaying transmissions between wireless LAN devices.
AdHoc (Peer-to-Peer) mode
A type of wireless transmission.
Mode used for exchanging data between devices that have wireless LAN PC cards installed,
without going via an access point.
Channel
Wireless LAN devices that comply with IEEE802.11b transmit using a specified wireless channel
from wireless channels 1 to 14. (This device has 11 channels (1 to 11) that can be used. The
channels that can be used vary with the country or region.)
It may be possible to use the same channel on a different network, however, the transmission
speed may be reduced.
It is recommended to use a different channel.
DHCP (Dynamic Host Configuration Protocol)
When building a TCP/IP network, it is necessary to assign IP addresses to devices on the network.
This protocol assigns IP address automatically.
DHCP client function
This function allows for automatically receiving IP addresses from DHCP servers connected to the
same network.
This function is found in most computers. If the computer is connected to the DHCP server on the
network, it is also possible to automatically get an IP address for the computer.
DHCP server
This server allows automatically assigning IP addresses, subnet masks, and gateway addresses to
devices connected on the network. By using this function, a computer connected to the DHCP
server via a wireless connection can also automatically receive an IP address.
Gateway
Device which relays transmissions between different networks.
IEEE802.11b
One of the international standards for wireless LANs. Allows for wireless transmissions using a
wireless frequency of 2.4GHz and a maximum speed of 11Mbps.
Infrastructure (Access Point) mode
A type of wireless transmission.
Mode used for exchanging data between devices connected to wired LANs and devices connected
to wireless LANs.
IP Address
When configuring a network using TCP/IP protocol, every device must have a number assigned to
it. This number is called an IP address.
An IP address is necessary to avoid duplicates or overlapping on the network.
LAN (Local Area Network)
A network built in a comparatively narrow area.
