A county RF engineer will run a measured survey before replacing APs in a health-department clinic. What practice best keeps the measured results trustworthy?
Select an answer to reveal the explanation.
Short Explanation
Survey adapters are like bathroom scales—if they’re off by five pounds, every diet plan lies. Calibrate (or use known-good calibrated gear) and stick to a written walk process so dBm and noise numbers mean the same thing tomorrow. Pretty predictive maps don’t excuse sloppy meters.
Full Explanation
Measured designs and validations depend on survey adapters whose amplitude response is known and a repeatable methodology (height, pace, bands, dwell). Calibration and process control make RSSI/SNR/noise comparable across engineers and revisit dates. Uncalibrated USB NICs, single-band shortcuts, or skipping measurement because a predictive plot looks favorable undermine acceptance evidence.
