802.11
Transfer mode for wireless network
communication (WLAN) published in
1997 by the IEEE (extensions e.g.
802.11b, 802.11g).
802.11b
Currently the most widely distributed
transfer mode (extension of 802.11).
Data transfer: 11 Mbit/s gross (approx.
50 % net), frequency band 2.400 to
2.485 GHz.
802.11g
Extension of 802.11. Less widely used
compared with 802.11b, but greatly on
the increase. Data transfer: 54 Mbit/s
gross. Frequency range: 2.400 to 2.485
GHz.

Access point
Centre of a wireless infrastructure
WLAN. All WLAN subscribers log into
the access point.
The access point regulates the data
traffic between the subscribers, and
forms the interface with other networks (e.g. to the Internet).
An access point can, for example, be a
WLAN router.
Ad-hoc network
WLAN without a central structure
(without an access point). WLAN subscribers form a spontaneous network in
which all subscribers are equal.
Requirement: all devices have a wireless network adapter and can be operated in ad-hoc mode. You cannot operate the handset in an ad-hoc network.
ADSL (Asymmetric Digital Subscriber Line)
Special form of DSL.
ALG (Application Layer Gateway)
NAT control mechanism of a router.
Many routers with integrated NAT use
ALG. ALG lets the data packets in a SIP
connection pass and adds the public IP
address of the secure private network.
The router's ALG should be deactivated
if the SIP provider offers a STUN server
or an outbound proxy.
See also: Firewall, NAT, Outbound
Proxy, STUN.
ATM (Asynchronous Transfer Mode)
High-speed network technology for
transferring text, voice, audio and
video.
Authentication
Restriction of access to the WLAN by
use of a password to log in. The handset supports authentication with security standard 802.1x.
For further security settings, see
Encryption.
B
Block dialling
Enter the complete number, and correct it if necessary. Then pick up the
receiver or press the handsfree key to
dial the number.
Bridge
Connection between several network
segments at network level 2, e.g. a
wired and a wireless network.
See also: Gateway, Router).
Broadband Internet access
See DSL.
Broadcast
A data packet that is not directed to a
particular recipient but to all network
subscribers e.g. with UDP transport
protocol).
BSSID (Basic Service Set ID)
Clearly distinguishes one WLAN from
another. In an infrastructure WLAN
the BSSID is the MAC address of the
access point.
