Optimizing Performance
6-13
All other stations will defer their transmissions for the duration of the
“radio-silence time” identified in the CTS message.
Enabling RTS/CTS Medium Reservation
1. Start the A PManager program, select the Access Point that services the
wireless cell where you suspect poor performance caused by a hidden
station problem and click the
Edit
button.
2. Select the
Wireless Interfaces
tab.
3. Choose the socket that contains the network interface that suffers from a
hidden station.
4. Click the
Advanced
button.
5. Click the
RTS/CTS Medium Reservation
check box.
6. In the
Threshold
field, enter a value in the range of 0 to 2347.
By default, the RTS/CTS medium reservation threshold is 2347 (disabled)
which means that RTS/CTS will not be used.
❏
In a network using RTS/CTS medium reservation, a typical setting for
the medium reservation threshold is 500.
❏
Alternatively enter a value of your choice.
The value you enter here will determine when the Access Point will issue a
Request to Send (RTS). For example, if the value you select is 500:
❏
The Access Point will send use the RTS/CTS protocol for each message
that exceeds the length of 500.
❏
Messages with a length that is shorter than 500, will be transmitted
according to the standard CSMA/CA protocol.
7. Click
OK
to return to the Interface tab.
8. Click
OK
again to save the new configuration to the Access Point and to
return to the main AP Manager window.
9. Next create a backup-file of the new configuration (see “Step 4 - Create a
Back-up of the Configuration” on pag e4-6).
Frequency Channel Management
When your network consists of more than one Access Point, we recommend that
you alternate sub-channel frequencies between adjacent Access Points to
provide more bandwidth to the wireless stations in each cell.
The number of available channels is subject to local radio regulations that apply
in your country. A list of supported channels for your country can be found in
the online documentation of the Wireless Client Adapter.
Dual Channel Configuration
A Dual Channel system could look as follows (see Figure 6-4):
