Field Meaning Default
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
(Cyclical Redundancy Checking).
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.
long
Transmit 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.
