A fire-station WLAN was installed from a predictive model targeting -67 dBm coverage and adequate SNR for voice. What validation step is required after install before declaring success?
Select an answer to reveal the explanation.
Short Explanation
Pretty predictive greens are not a receipt. After the fire-station APs are up, walk it with real measurements against -67 dBm and SNR. That is when you know voice coverage is real.
Full Explanation
Post-deployment RF validation surveys compare measured RSSI/SNR (and related metrics) on the installed network to the design targets such as -67 dBm voice-grade coverage. Predictive maps guide design but cannot replace measured validation after construction, furniture, and interference realities appear. Gateway pings or blindly raising power do not demonstrate that coverage and SNR goals were met.
