Wi-Fi 6 clients underperform on a busy city permitting SSID even though RSSI is acceptable. Captures show little UL OFDMA activity. What should the analyst relate to multi-user uplink scheduling?
Select an answer to reveal the explanation.
Short Explanation
OFDMA uplink is a conductor cueing many instruments at once—the Trigger frame is the baton. If the busy permitting SSID never shows those cues, don’t just stare at RSSI; ask whether multi-user uplink scheduling is actually on stage.
Full Explanation
In HE (Wi-Fi 6), the AP uses Trigger frames to schedule uplink OFDMA resource units for multiple clients. Sparse Trigger activity on a busy BSS suggests UL OFDMA is not contributing as expected. Experts correlate Trigger presence with HE capabilities and AP scheduling features rather than judging performance from RSSI alone.
