1. Start the RLM Manager program, select the Radio Link Module that

button.
2. Select the
:LUHOHVV ,QWHUIDFHV

3. Choose the socket that contains the network interface that suffers from
a hidden station.

5. Click the
576&76 0HGLXP 5HVHUYDWLRQ
check box.
6. In the
7KUHVKROG
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 RLM will
issue a Request to Send (RTS). For example, if the value you select is
500:
• The RLM will send 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.
