CTS 264: Spectrum Analysis

What this episode covers

It’s been a while since we last talked about Spectrum Analysis (SpecAn). It was all the way back on Episode 39. In this episode, we’re going to define what Spectrum Analysis is. We’ll then discuss why we should perform SpecAn. Maybe it’s because you want to locate a source of interference. What are the different scenarios when you would perform spectrum analysis? It could be done during the validation survey as part of your verification of Wi-Fi operation. We’ll discuss how we, Rowell and François, perform Spectrum Analysis with our own tools. We use a combination of the Ekahau Sidekick and Metageek Chanalyzer. But after you perform Spectrum Analysis, how do you document your findings? Be sure to check out the YouTube video recording to get the visual representation of the podcast. In the video we simulate sources of interference, what it looks like from the frequency density view, waterfall view, and channel utilization view, and talk about the impact of interference.
