A city hall public lobby shows roughly 90% channel utilization during lunch, and visitors report extremely slow Wi-Fi even when associated. What best describes the performance situation?
Select an answer to reveal the explanation.
Short Explanation
A packed radio channel is like a one-lane bridge at rush hour—everyone is 'on the road' but barely moving. High utilization means the medium is congested, so apps crawl. Look at airtime and density, not just whether the SSID appears.
Full Explanation
High channel utilization indicates the RF medium is busy with transmissions, retries, or contention, leaving little airtime for useful client traffic. Associated clients therefore experience poor throughput and latency. Technicians should recognize congestion symptoms and escalate capacity/channel planning as appropriate without inventing unrelated security causes. Domain 5.2 covers this RF/environment performance case.
