Access Point
An Access Point, such as the Gigaset SE551 WLAN dsl/cable, is the centre of a wireless
local network (WLAN). It handles the connection of the wireless linked network
components and regulates the data traffic in the wireless network. The Access Point also
serves as an interface to other networks, e.g. an already existing Ethernet LAN or via
modem to the Internet. The operating mode of wireless networks with an Access Point
is called infrastructure mode.
Ad-hoc mode
Ad-hoc mode describes wireless local networks (WLAN) in which the network
components set up a spontaneous network without an Access Point, e.g. several
notebooks in a conference. All the network components are peers. They must have a
wireless network adapter.
Authentication
Authentication checks the true identity of a PC against 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 characteristics, e.g. different
linking such as Ethernet and wireless LANs. Linking individual segments via Bridges
allows local networks of practically unlimited size.

Broadcast
A Broadcast is a data packet not directed to a particular recipient but to all the network
components on the network. The Gigaset SE551 WLAN dsl/cable does not broadcast
packets on; they always remain within the local network (LAN) it administers.
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 range thus saving a great deal
of configuration 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 SE551 WLAN dsl/cable includes a DHCP server and can automatically assign
IP addresses for the PCs on its local network. For certain PCs you can specify that their
IP addresses are never changed.
