At a busy city lobby kiosk, the client shows strong RSSI yet throughput is poor and rates stay low. A spectrum check shows elevated noise, yielding low SNR. What performance issue does this illustrate?
Select an answer to reveal the explanation.
Short Explanation
Loud signal next to a louder noisy room still gives you a muddy conversation. RSSI can look fine while noise crushes SNR, and rates tumble. Chase the noise, not just the bars.
Full Explanation
RSSI measures received signal strength but does not by itself describe usable quality. Elevated noise floor reduces SNR even when RSSI appears strong, forcing lower data rates and poor throughput. Technicians should evaluate noise and SNR alongside RSSI when troubleshooting performance. This RF low-SNR scenario is a Domain 5.2 performance issue distinct from simple coverage holes.
