A strong signal with insufficient busy-room capacity
A fictional training room meets its supplied received-signal requirement during an empty-room check. During a full session, many active clients share the service and experience delayed interactive applications. Provided observations show high airtime utilization and retries, while authentication and address assignment succeed. A colleague proposes declaring the design accepted because the heatmap is green. Another separates the coverage result from the concurrent-demand requirement and asks for client, channel-reuse, interference, uplink and power evidence. This written case makes no scan, transmission or AP change. It asks which acceptance criterion remains unproven and why neither maximum transmitter power nor a universal channel-width rule is a justified remedy from the supplied information alone.
1. Which result is still unproven?
Read the worked answer
Coverage met the supplied measurement criterion, but representative peak capacity and user application behavior remain unproven. Signal strength alone is not shared-airtime capacity.
2. What should an authorized design review compare?
Read the worked answer
Evaluate actual concurrent demand, client capability, channel width/reuse, interference, retries, uplink and power constraints. Test a narrow alternative against the agreed busy-period outcome rather than a universal default.
