Municipal environmental sensors send short periodic telemetry but experience delayed bursts when WMM-Power Save is enabled on their WLAN profile. What should the engineer evaluate?
Select an answer to reveal the explanation.
Short Explanation
Sleepy sensors miss their alarm clock when power-save buffers hold the mail. Match WMM-PS behavior to the telemetry schedule—or change how they sleep—so short uplinks leave on time.
Full Explanation
WMM-Power Save can buffer frames until the client wakes, which may delay periodic sensor telemetry. Engineers must assess power-save interaction with uplink cadence and adjust PS mode, DTIM/listen intervals, or application timing. Disabling encryption, only lengthening beacons, or scavenger marking does not correctly address the PS timing conflict.
