Question 900
A warehouse deployment needs accurate client location, but APs were installed with no stable coordinate or floor map assignment. Which first diagnostic check is most useful before changing the network?
Explanation
Correct Answer
This check collects evidence at the layer implicated by the symptom: client localization depends on accurate reference positions and RF geometry. Examine the evidence before choosing the corrective change.
Incorrect Answers
This would be a reasonable check when a VoIP design attempts to solve poor call quality solely by raising AP power while clients still transmit at weak power levels, but is less direct for the issue at hand: client localization depends on accurate reference positions and RF geometry.
This would be a reasonable check when a retail site uses multiple AP models but a uniform antenna-gain configuration that overstretches permitted EIRP in some areas, but is less direct for the issue at hand: client localization depends on accurate reference positions and RF geometry.
This would be a reasonable check when a stadium's WLAN uses 80 MHz channels everywhere, producing excessive overlapping BSSs during a sold-out event, but is less direct for the issue at hand: client localization depends on accurate reference positions and RF geometry.
