Probe Response

A unicast management frame from an AP answering a probe request with BSS information.

Definition

Probe responses contain much the same information as beacons, minus the TIM. They are sent at the lowest basic rate and acknowledged by the client. Probe response suppression features reduce unnecessary airtime use.

Exam tip

Probe responses are unicast and ACKed; beacons are broadcast and not ACKed.
