Access point
An access point such as the Gigaset SE366 WLAN is the central element in a wireless
local network (
An access point such as the Gigaset SE366 WLAN is the central element in a wireless
local network (
). It handles connection of the wireless-linked network compo-
nents and regulates data traffic in the wireless network. The access point also serves as
an interface to other networks, for example an existing
an interface to other networks, for example an existing
LAN or via a modem
to the
. The network mode for wireless networks with an access point is called
.
Ad-hoc mode
Ad-hoc mode describes wireless local networks (WLAN) in which the network compo-
nents set up a spontaneous network without an access point, e.g. several notebooks in
a conference. All the network components are peers. They must be equipped with a
wireless network adapter.

AES
Advanced Encryption Standard
AES is an encryption system that was published as a standard in October 2000 by the
National Institute of Standards and Technology (NIST). It is used for WPA encryption. A
distinction is made between the three AES variants AES-128, AES-192 and AES-256 on
the basis of their key lengths.

Authentication
Authentication checks the true identity of a PC on the basis of a particular property.

Bridge
A bridge connects several network segments to form a joint network, e.g. to make a TCP/
IP network. The segments can have different physical properties, for example different
connections such as Ethernet and wireless LANs. Linking individual segments via
bridges makes it possible to build local networks of practically unlimited size.

DHCP
Dynamic Host Configuration Protocol
DHCP handles the automatic assignment of IP addresses to network components. It was
developed because in large networks – especially the Internet – the defining of IP
addresses is very complex as participants frequently move, drop out or new ones join.
A DHCP server automatically assigns the connected network components (DHCP clients)
dynamic addresses from a defined IP address pool, thus saving a great deal of configu-
ration work. In addition, the address blocks can be used more effectively: Since not all
participants are on the network at the same time, the same IP address can be assigned
to different network components in succession as and when required.
The Gigaset routers include a DHCP server and can automatically assign IP addresses for
the PCs in their local network.
