Auto. channel selection lfc 2
Automatic channel selection for the second WLAN module.
Settings for the second WLAN module are ignored if the managed
device has only one WLAN module.
Encryption
Encryption of communications over the control channel. Without encryp-
tion the control data is exchanged as plain text. In both cases authentica-
tion is by certificate.
Possible values:
DTLS, no, default
Default:
DTLS
Special values:
'Default' makes use of the encryption method defined in the 'Options'
area.
Double bandwidth
LANCOM Access Points compliant with IEEE 802.11n optionally offer the
activation of double the bandwidth.
A wireless LAN module normally uses a frequency range of 20 MHz in
which data to be transmitted is modulated to the carrier signals. 802.11a/
b/g use 48 carrier signals in a 20MHz channel. The use of double the fre-
quency range of 40 MHz means that 96 carrier signals can be used, resul-
ting in a doubling of the data throughput.
802.11n can use 52 carrier signals in one 20 MHz channel for modulation
and up to 108 in a 40 MHz channel. The use of the 40 MHz option for
802.11n therefore means a performance gain of more than double.
Possible values:
Auto, No
Default:
Auto
