None - no protect mechanism is used. It is the default setting.

CTS-only - also known as CTS-to-Self; AP issues a CTS frame to itself

before sending data. All clients will not transmit during the time.

RTS-CTS - AP sends a RTS frame, waits for the clients CTS frame and

then sends the data packet. It allow more robust operation, but at

the expense of additional overheads.

3. Specify frame size in byte between 0 and 2347 bytes on RTS/CTS

Threshold; 2346 is default setting.

If a frame is smaller than the RTS/CTS threshold, it will be sent by the

AP without modification. If a frame is larger than the RTS/CTS

threshold, then two frames will be sent by the AP. The first frame is an

RTS (request to send) frame. After the RTS frame is sent, the AP listens

for the corresponding CTS from the target client. Upon reception of

the CTS, the AP then sends the data frame. There are trade-offs

when considering what value you should set for the RTS/CTS
