operational mode.
Ad-Hoc mode
Both mode
AP mode
Wireless Bridge mode
To configure several wireless LAN groups within a same area, a
unique channel should be set per each group, and it is necessary
to set each channel at the place 5 channels apart in order to avoid
the interference between the wireless LANs. In the case 3 groups
of the wireless LAN are configured in the close area, it will be
necessary to make the setting at 1CH, 6CH and 11CH to the
respective group.

10.4. Data Rate
There are 5 choices: 1Mbps, 2Mbps, 5.5Mbps, 11Mbps and the automatic
setting.
When the automatic setting is selected, Wavit11
makes communication in the fastest possible rate, and
this depends on the equipment at the other end. If the
communication environment is degraded and making
communication in the present data rate becomes
impractical, the data rate will be lowered and the
wireless LAN communication will continue.

10.5. Roaming
This is a way to set whether the Wavit11does a roaming or not.
What is Roaming?
This function can be activated in an environment where
multiple Access Points exist. If the wireless LAN under
communication with a certain Access Point moves and fails
in receiving the radio wave, the roaming function will enable
Wavit11 to change the destination to the other nearby Access
Point. If Wavit11 switches the Access Point successfully, it
can send and receive the wireless LAN data without
interruption, and that it can access the network without any
interruption.
Setting up of Roaming function will be possible only if the
operational mode is as follows:
Infrastructure mode
AP mode

10.6. Hidden Node Compensation
Depended on the placement of multiple wireless LANs, there is a case that the
wireless LAN communication disturbance caused by other wireless LANs takes
place and the data rate may be fallen off. If the Hidden Node Compensation is
set to Enable, the Wavit11 seizes the wireless LAN communication line prior to
the actual data transmission, so it can mitigate the mutual disturbance of
wireless LAN communication and the degradation of data rate.
What is Hidden Node?
In the wireless LAN system, many wireless LANs
communicate each other on the same frequency. Normally every
wireless LAN senses whether or not another wireless LAN has
already started the wireless LAN communication so as not to
disturb the already started wireless LAN communication.
However, some wireless LANs disturb the already started
wireless LAN communication transmitting the data without
sensing the existence of another wireless LAN communication.
Such a kind of wireless LAN that may disturb the other wireless
LAN communication is called Hidden Node.

10.8. RTS Threshold
In the case that the Hidden node compensation is set to Enable, setup of RTS
threshold will be possible.
The Wavit11 seizes the wireless LAN communication line prior to actual data
transmission if the data length is greater than RTS Threshold. When the Hidden
node compensation is set to Enable, the initial value is 0, therefore, the Wavit11
seizes the wireless LAN communication line prior to every length of actual data
transmission.
The wireless LAN performance will improve when this
RTS Threshold is enlarged, in the case that Hidden node
disturbance is not so violent. Check the performance by
modifying the RTS threshold, when you modify the value
from the initial value, because the optimal RTS threshold
depends on the placement and application of wireless LAN.

Wavit11 User's Manual
10.9. Fragmentation Threshold
In the case that the transmitted data do not correctly reach the wireless LAN
on the partner side, the Wavit11 will retransmit the data predefined times. This
retransmission occurs frequently by a communication error under poor
communication condition and the performance of the wireless LAN network
sometimes deteriorates.
There is a way to mitigate the performance deterioration, that is the
retransmission of divided frame. Thus, the wireless LAN frame should be
divided into small pieces, and here is a way to set the size of divided frame.
All frames are sent without any data frame division in
default setting.

10.10. Short Retry Limit
In the case that the transmitted data do not correctly reach the wireless LAN
on the partner side, the Wavit11 will retransmit the data predefined times and the
number of retransmission times is set here. In Short Retry Limit, the number of
retransmission is set, for the data frame whose length is below RTS threshold.
If a big value is set needlessly, the Wavit11 may try to
retransmit data many times to the wireless LAN at which the
radio wave cannot get, so the performance of the whole
wireless LAN can be deteriorated. Closely examine the degree
of performance required by the application, if you modify the
setting.
