Automatic Session Splitting, now in Chanalyzer

Chanalyzer is a must-have tool for troubleshooting Layer 1 issues, and ruling out RF interference. Just walk around, and keep an eye out for times of high utilization (when the density and waterfall views have a lot of red coloration).

But what to do when you’re not on site to catch the suspected interference in action? One common tactic among those trying to troubleshoot issues for their customers is to leave behind a laptop running Chanalyzer for a day, then examine the recording looking for the “red spots” of high utilization.

What becomes problematic is as a recording becomes longer, the colors in the Waterfall Navigation pane becomes compressed to the point of looking for a needle in a haystack.

Mentally split the Navigation Pane into 24 parts (one for each hour)

If your recording was 24 hours long, then there would have to be high utilization for over an hour straight in order for it to be easy to spot.

In order to combat this problem, the latest release of Chanalyzer introduces Automatic Session Splitting. By default, your current recording sessions will be cloned every two hours. This means that when it comes time for you to analyze recording data spanning several hours, you can quickly cycle through your sessions, look for red, and take it from there!
