Preamble
Type
In the IEEE 802.11 standard, the "preamble" is used to
synchronise the Emitter and Receiver correctly. The "long
preamble" is generally commonly used. For reasons of
bandwidth gain, this standard proposes reducing the
length of the "preamble".
“Preamble Type” defines the length of block CRC (
C
yclical
R
edundancy
C
hecking).
If your network does not include any peripheral 802.11b,
you can configure the type of preamble on
short
for an
optimal result.
The type of preamble
long
must be used if the peripherals
802.11g and 802.11b are both present on the network.
In the scroll down list, select
long
to keep a 128 bit
"preamble" or
short
to reduce it to 56 bits.

Power
If 802.11 h is selected, in the scroll down list select the
cyclical emission ratio (20%, 40 %, 60 %, 80 % or 100 %)
at which you want to transmit.
Note:
The power rate will be selected according to your
environment.
