When a station sends an RTS, the Duration/ID field notifies the other stations that they must set their NAV. Which of the following values should the stations set their NAV to?
Explanation
Answer - D - The stations should set their NAV values to the time necessary to transmit the CTS, Data, and ACK frames.
Key Takeaway: When the RTS is sent, the value of the Duration/ID field is equal to the time necessary for the CTS, Data, and ACK frames to be transmitted. The Duration/ID field can be interpreted in two ways depending upon the frame type. In the Power-Save Poll messages, this field is the Station ID. In all other frames, this is the duration value used to calculate the NAV.
