You were previously onsite at XYZ's facility to conduct a pre-deployment RF site survey. The WLAN has been deployed according to your recommendations and you are onsite again to perform a post-deployment validation survey.
When performing this type of post-deployment RF site survey voice over Wi-Fi, what is an action that must be performed?
When performing a post-deployment validation survey for voice over Wi-Fi, it is crucial to conduct application analysis with an active phone call on a VoWiFi handset. This ensures that the WLAN supports high-quality voice communication by directly testing the performance of the system under real usage conditions. Spectrum analysis, frequency-band hopping analysis, and protocol analysis are also important, but the primary action for validating voice over Wi-Fi is testing with actual voice calls for real-time performance assessment.
Correct answer is: A. Spectrum analysis to locate and identify RF interference sources.
Answer C is correct. You first test the performance with a VoWifi set. If you notice bad performance you can do a Spectrum analysis to immediately locate the interference source.
