SSID
Service Set Identifier
The SSID is used to identify the stations in a wireless network (

). 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 

 is assigned to a network component manually during network con-

figuration. Unlike a 

, a static (fixed) IP address never changes.

Subnet
A subnet divides a network into smaller units. 

Subnet mask
The subnet mask determines how parts of the 

 of a network represent 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 

. Channel bundling doubles the maximum trans-

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 

, 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 

 is part of the 

 protocol family. TCP handles data transport 

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