Which metric is most commonly used to measure wireless network installation quality during a site acceptance test?
Answer: Received Signal Strength Indicator (RSSI)
RSSI is the primary metric used during site acceptance testing to verify that signal coverage meets the design specification.
During a wireless deployment QC walkthrough, a technician notices intermittent packet loss on a newly installed AP. What is the FIRST step in the troubleshooting process?
Answer: Verify physical cable connections and PoE switch port status
Verifying physical connections and PoE port status is the foundational first step before assuming hardware failure.
What does a post-installation RF spectrum analysis primarily help identify?
Answer: Co-channel interference and rogue AP sources
RF spectrum analysis reveals interference sources such as co-channel overlap and unauthorized rogue access points.
A QC checklist for a wireless installation should include verification of which of the following?
Answer: AP mounting height and antenna orientation
AP mounting height and antenna orientation directly affect coverage patterns and must be verified against the RF design.
In a continuous improvement context, which framework uses Define, Measure, Analyze, Improve, and Control phases?
Answer: Six Sigma DMAIC
Six Sigma's DMAIC methodology provides a structured five-phase approach to process improvement and defect reduction.
When performing a wireless site survey for QC validation, a technician should use a survey tool set to which client adapter mode?
Answer: The same band and capabilities as the target client devices
Using survey hardware that matches target client capabilities ensures measurements reflect real-world user experience.
Which document serves as the primary reference for verifying that a wireless installation meets the original design intent during QC review?
Answer: As-built RF design and heat maps
As-built RF designs and heat maps document the intended coverage and serve as the baseline for QC comparison.
