I tried out this software which I downloaded after reading this helpful article by Lloyd Burrell. That’s my apartment coverage pictured. I have to try it again at some point as I don’t have a floorplan of the apartment and not sure how well I did the survey but it did show a ton of wireless networks and radiation in this area 🙁 If any one else tries this out and has any tips, please post in the comments
