Question

Quizplus · Accepted Answer

Passive scanning is used to reduce the time taken by clients to locate and associate to access points when they are roaming.
Key Takeaway: A client station constantly monitors beacons sent by all access points in its vicinity. It decides which access point would be the best candidate for re-association if the current link should fail. Time is saved in re-association, making roaming a more seamless process.
