A county operations-center capacity complaint shows frequent Block Ack activity on a busy SSID. How should the analyst distinguish which aggregation method is primarily in play?
Select an answer to reveal the explanation.
Short Explanation
Picture packing county mail: A-MSDU is stuffing several letters into one envelope; A-MPDU is bundling several envelopes onto one truck with a signed delivery checklist—the Block Ack. When you see that checklist pattern, you’re looking at A-MPDU in the wild.
Full Explanation
A-MSDU aggregates multiple MSDUs into one MPDU; A-MPDU aggregates multiple MPDUs and typically relies on Block Ack for selective acknowledgment. Capture evidence of Block Ack sessions therefore points to A-MPDU behavior during capacity analysis. Distinguishing the two prevents mis-tuning aggregation or blaming the wrong MAC feature for throughput complaints.
