Access Point
An access point, such as a Gigaset router, 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 modus 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.
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. A Gigaset router does not pass 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 pool range thus saving a great deal of
configuration work. It also allows address pools to 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.
A Gigaset router includes a DHCP Server and so it 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.
