You plan to use a Basic or Extended service set. Which of the power management features populate the traffic indication map, or TIM, with station information?
Explanation
Answer - A - The Power-save polling mode populates the traffic indication map, or TIM, with station information when using a Basic or Extended service set.
Key Takeaway: When a station is not sleeping, the access point does not need to buffer packets destined to that station. If a station is sleeping, the access point should buffer its packets so that the packets are not lost. TIM is used to notify stations using power-save polling, or PSP, mode that they have packets buffered at the access point. Client stations use power-save poll frames to notify the access point to send the buffered packets.
