Glossary
Access point
A networking device with both wireless
communication interface and telephone
line or Ethernet interface, which bridges
across the wireless LAN and wired LAN.
Ad hoc demo mode
A transmission method for devices
equipped with a wireless LAN card (for
example, a PC and AIBO), which does
not require the access point. In ad hoc
demo mode, you must specify wireless
channel and WEP key for both AIBO and
a personal computer. When you select
ad hoc demo mode, you cannot specify
SSID.
32
DHCP (Dynamic Host
Configuration Protocol) server
When you construct a network using
TCP/IP, an IP address must be specified
for all the devices within the network.
When a DHCP server is included within
the network, it assigns an IP address
automatically for all devices. The access
point or Windows NT/2000 server can
serve as the DHCP server.
IBSS (Independent Basic Service
Set) Peer-to-Peer mode
When you set at least one PC within the
wireless LAN network to IBSS Peer-toPeer mode, all devices within the
network can communicate with each
other without the need of an access point.
The only difference between IBSS Peerto-Peer mode and ad hoc demo mode is
that SSID can be specified for the IBSS
Peer-to-Peer mode while it cannot be
specified for the ad hoc demo mode.
When there is no access point within the
network, at least one personal computer
must be set to IBBS Peer-to-Peer mode
and the rest of the personal computer and
the wired LAN devices must be set to
infrastructure mode.
IEEE802.11b
A standard for wireless LAN network
which uses the 2.4 GHz band for
communication. Maximum transmission
rate is 11 Mbps. This LAN card
conforms to IEEE802.11b.
Infrastructure mode
Also referred to as “Access point mode.”
This mode is used when a device
equipped with a wireless LAN card
communicates with the access point. In
this mode, the wireless channel specified
by the access point is used for
communication. For AIBO, you must
specify SSID and WEP key which
matches those on the access point.
SSID (Service Set ID)
Also referred to as “access point ID” or
“group name.” The SSID is specified
through the access point or the personal
computer which is set to IBSS Peer-toPeer mode, and is used for
communication within wireless LAN
network as the network name.
The SSID can be entered using up to 32
alphanumeric characters.
IP address
Number used for identifying the device
within the TCP/IP network. An IP
address consists of four numbers each of
which is from 0 to 255.
Example: 192.168.1.1
10.0.1.1
Subnet mask
An IP address consists of four numbers
each of which is from 0 to 255 (see IP
address). For more efficient operation,
an IP address is divided into two
components: network component and
host component. The subnet mask is the
value set for dividing the IP address into
the network segment and host segment.
In subnet mask, the digits specified as
“1” (in binary code) determines network
component.
Example: The network component and
host component of the device whose IP
address is 192.168.1.1 when the subnet
mask is 255.255.255.0
192.168. 1: network component
1: host component
LAN (Local Area network)
A relatively small network usually
constructed using the Ethernet, with
transmission rate from 10Mbps to
100Mbps. When an access point is used,
a wireless LAN and wired LAN can be
connected.
33
TCP/IP (Transmission Control
Protocol/Internet Protocol)
A protocol which the personal computer
within the network uses for
communication. TCP/IP is used in
Internet and is used the most world wide.
This LAN card uses TCP/IP for
communication. In order to
communicate using TCP/IP, a device
requires the IP address which works as
ID number.
WEP (Wired Equivalent Privacy)
WEP encrypts data transmit through the
wireless LAN to prevent tapping of
information.
To activate WEP, characters to be used as
the key for encrypting the data being
transmit using the wireless LAN must be
specified. Input five alphanumeric
characters.
34
Wireless channel
In IEEE802.11b wireless LAN standard,
2.4 GHz band is divided into 14
channels. To prevent a transmission jam,
separate channels can be specified for
different wireless networks which are
close to each other. This LAN card can
use channels 1 to 11. In infrastructure
