Glossary
SSID
Service Set Identifier
The SSID is used to identify the stations in a wireless network (WLAN). All wireless net-
work components with the same SSID form a common network. The SSID can be
assigned by the network operator.
Static IP address
A static IP address is assigned to a network component manually during network con-
figuration. Unlike a
Subnet
A subnet divides a network into smaller units.
Subnet mask
The subnet mask determines how parts of the
network number and how many the computer number.
The subnet mask in a network administered by the Gigaset SE551 WLAN dsl/cable is
always 255.255.255.0. That means the first three parts of the IP address form the net-
work number and the final part is used for assigning computer numbers. The first three
parts of the IP address of all network components are in this case always the same.
Super G
Super G is an extension of
fer rate to 108 Mbps. Unlike other technologies (e.g. 125 Mbps technology) which work
by compressing data, here the transfer rate is actually doubled. If data is already com-
pressed (ZIP, RAR, MP3, MPEG etc.) data compression offers no significant improve-
ments.
Switch
A switch, like a Hub, is an element used to link different network segments or compo-
nents. Unlike a Hub however, the Switch has its own intelligence that enables it to for-
ward packets to only the subnet or network component they are meant for.

TCP
Transmission Control Protocol
The TCP Protocol is part of the
between communication partners (applications). TCP is a session-based transmission
protocol, i.e. it sets up, monitors and terminates a connection for transporting data.
