Glossary

Access point
Device used for relaying transmissions when using
the Infrastructure mode.
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.
BMP
Short for Bitmap. One type of image file format
used normally in a Windows environment. This
software supports only non-compressed file types
only.
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 setting up a network using TCP/IP, an IP
address must be assigned to each device that will
be connected to the network. This protocol will
perform the above procedure automatically.
DHCP client function
This protocol 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 to assign IP
addresses, subnet masks, and gateway
addresses to devices connected on the network.
In using this function, a computer connected to
the DHCP server via a wireless connection can
also automatically receive IP addresses.
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.
JPEG
Short for Joint Photographic Experts Group. One
type of widely used image file format.
LAN (Local Area Network)
A network built in a small self-contained network.
MAC Address (Media Access Control
Address)
A fixed number assigned to individual network
devices.
It is assigned by the manufacturer at the time of
shipping and does not overlap with other devices.
Maximum Assign Number
The maximum number of IP addresses that the
DHCP server can automatically assign.
Subnet Mask
A parameter used on a TCP/IP network, that is used
when an IP address is separated into network
address and host address.
