Figure 4-3 RTS Threshold
Thus, the RTS Threshold mechanism provides a solution to prevent data collisions. When you enable RTS
Threshold on a possible hidden station, this station and its Access Point will use a Request to Send/Clear to
Send protocol (RTS/CTS). The station will send an RTS to the Access Point, informing that it is going to
transmit the data. Upon receipt, the Access Point will respond with a CTS message to all stations within its
range to notify all other stations to defer transmission. It will also confirm with the requesting station that
the Access Point has reserved it for the time frame of the requested transmission.
Normally, the Disable option (default) is selected when you are not concerned with the Hidden Node
problem. When the Hidden Node problem becomes an issue, please select Enable and specify the packet
size. The RTS function will be activated if the packet size exceeds the value you set. It is highly
recommended that you set the value ranging from 0 to 2432.
NOTE: Enabling the RTS Threshold causes redundant network overhead that
could negatively affect the throughput performance instead of providing a
remedy.
Use WEP (Wired Equivalent Privacy)
To prevent unauthorized wireless stations from accessing data transmitted over the network, ZyAIR 100
offers highly secure data encryption known as WEP. If you require high security in transmission, please
select Enable and click the Key List button.
