ZyAIR G-405 User's Guide
Stations can send frames smaller than the specified RTS Threshold directly to the AP without the RTS
(Request To Send)/CTS (Clear to Send) handshake.
You should only configure RTS Threshold if the possibility of hidden nodes exists on your network and
the "cost" of resending large frames is more than the extra network overhead involved in the RTS (Request
To Send)/CTS (Clear to Send) handshake.
If the RTS Threshold value is greater than the Frag Threshold value, then the RTS (Request To
Send)/CTS (Clear to Send) handshake will never occur as data frames will be fragmented before they reach
RTS Threshold size.
