Glossary

Access point
An access point such as the Gigaset SE366 WLAN is the central element in a wireless
local area network (

WLAN

). It handles connection of the wireless-linked network com-

ponents and regulates data traffic in the wireless network. The access point also serves
as an interface to other networks, e.g. an existing

Ethernet

LAN or via a modem to the

Internet

. The network mode for wireless networks with an access point is called

Infrastructure mode

.

Ad-hoc mode
Ad-hoc mode describes wireless local networks (

WLANs

) 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

.

Beacon
Beacons are data packets that are sent by devices in a wireless network to all other
devices to indicate that they are available and ready to receive. Beacons are also used to
synchronise the wireless network. A beacon interval is the period between two beacons
in milliseconds.

Bridge
A bridge connects several network segments to form a joint network, e.g. to build a

TCP/

IP

network. The segments can have different physical characteristics, e.g. different con-

nections such as

Ethernet

and wireless LANs. Linking individual segments via bridges

makes it possible to build local networks of practically unlimited size.

Broadcast
A broadcast is a data packet that is not directed to a particular recipient but to all the
components in a network. The Gigaset SE366 WLAN does not pass broadcast packets on
to the Internet; they always remain within the local area network (

LAN

) administered by

the Gigaset SE366 WLAN.

BSSID
Basic Service Set ID
The BSSID is used for unique differentiation between one wireless network (

WLAN

) and

another. In

Infrastructure mode

the BSSID is the

MAC address

of the

Access point.

In

wireless networks in

Ad-hoc mode

the BSSID is the MAC address of any one of the par-

ticipants.
