A county clinic's 2.4 GHz IoT hub sits under voice SSIDs and staff report choppy VoWLAN. How should spectrum analysis be used?
Select an answer to reveal the explanation.
Short Explanation
If the IoT hub is yelling on 2.4 under the nurses' voice SSID, spectrum is how you prove it's eating airtime — noise floor and duty cycle don't lie. Cranking TXOP or killing QoS without evidence is guessing. And lots of clinic IoT still loves 2.4 GHz.
Full Explanation
Coexistence problems require quantifying non-Wi-Fi or foreign 2.4 GHz energy against the voice BSS using noise-floor, duty-cycle, and utilization views. Raising EDCA TXOP or disabling QoS without spectrum proof does not address the interferer's airtime. Many IoT hubs remain on 2.4 GHz, so assuming they are only on 5 GHz channel 165 without measurement is unsafe.
