Municipal fleet tablets show low throughput despite high RSSI, and captures show missing or failed Block Ack sessions. What is the most likely protocol root cause to investigate?
Select an answer to reveal the explanation.
Short Explanation
Strong bars with slow apps is the classic 'loud radio, broken handshake' story—like shouting across a quiet street but never getting a signed receipt for the package. Fix the Block Ack session that makes aggregation work, not the RSSI meter.
Full Explanation
High RSSI does not guarantee efficient MAC aggregation. A-MPDU performance depends on successful Block Ack agreements and exchanges; failed BA sessions force less efficient acknowledgments and hurt throughput. Protocol captures that show BA problems therefore explain capacity complaints that RF strength alone cannot.
