Hi

Any help in finding the interference type on 5GHz band on 149 and above channels.

Hmmm… Not quite sure what the interference might be from… I’ll ask around the office and see if anyone has an idea.

I’m seeing the same thing when I scan. The closest interfere signature seems to be the one for Powermax Phone and that’s how Chanalyzer categorizes it. Does anyone have any idea how to track this down? My research suggests a wireless cell booster but we have none in any of our school buildings. What about wifi enable cars & trucks that have it built-in?

I would recommend playing hot/cold with the amplitude / signal strength of the interferer, similar to how I do in [this video](https://support.metageek.com/hc/en-us/articles/360036868514-Tracking-interference-with-a-Wi-Spy). The DBx with the omni-directional antenna should be capable of doing this.
