Q78 / 100
How does a wireless access point handle the "hidden node problem"?
Correct! Well done.
Incorrect.
The correct answer is D) By using RTS/CTS (Request to Send / Clear to Send) handshakes so the access point can coordinate transmissions between stations that cannot hear each other directly
D
Correct Answer
By using RTS/CTS (Request to Send / Clear to Send) handshakes so the access point can coordinate transmissions between stations that cannot hear each other directly
Explanation
In the hidden node problem, two stations can both reach the access point but not each other, causing collisions at the AP. RTS/CTS lets a station reserve the medium via the AP before transmitting, so the other hidden station defers, avoiding collisions.
