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.

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.
