u
Password mode: key coding
– Hexadecimal: 0–9 and A–F
– ASCII: 0–9, a–z and A–Z (case-sensi-
tive)
Depending on the access point, the key
may also contain special characters.
u
WEP Key (key): character string with
which the data is encrypted. The key
must be known to the access point.
u
Authentication mode
– Shared Key: to login, the handset
must show the WEP key. In this
mode, WEP is also used for authenti-
cation.
– Open System: all WEP clients are
enabled. There is no authentication.
Encryption with WPA PSK
Requirement
: All network subscribers
support the WPA standard.
WPA PSK is a version of WPA. New keys are
created in regular intervals using a key
word (Pre-Shared Key).
If data encryption with WPA PSK TKIP is
used in the WLAN, you must save the fol-
lowing parameters in the access profile:
u
Pre-Shared Key: Character string of 8 to
63 ASCII characters (case-sensitive).
Data is encrypted using the Pre-Shared
Key. The Pre-Shared Key is the same for
all subscribers in a WLAN.
Authentication and encryption with WPA
Requirement
: All network subscribers
support the WPA standard.
WPA (
W
i-Fi
P
rotected
A
ccess) uses more
complex procedures for key generation
than WEP and is therefore more secure.
The key the handset must produce during
registration is only used for establishing
the connection. Each user has their own
key.
WPA requires authentication with security
standard 802.1x (page 9).
WPA uses the following parameters:
u
Security: procedure for key generation
u
EAP Type: security distribution (page 9)
IP addresses
The subscribers to a network are identified
by their IP address.
The IP address consists of 4 parts (decimal
numbers between 0 and 255). The indi-
vidual parts are separated from each other
by dots (e. g. 192.68.233.2).
You can have the assignment of IP
addresses managed automatically by
DHCP (recommended) or can specify the
IP address of the handset manually.
The DHCP (

matic assignment of IP addresses. For
management via DHCP, you require a
DHCP server in the WLAN, e.g. in the
WLAN router. Most WLAN routers support
this setting.
