Would like some opinions on this capture I have done with Chanalyzer Pro. 3 AP93's have been deployed in a modular portakabin building, and wifi is very poor. Due to internal layout, there are 2 APs on the ground floor, and 1 on the top. The large open plan office upstairs, with one AP. has virtually no coverage with 80%+ packet loss (Ekahau Site Survey).
The 3 APs for some reason, are all on ch1. ARM is enabled, and Im sure they can see each other, as Im able to view the other APs bssid's from each AP. Ive noticed theres something around ch8, but have ruled this out.
I am very curious as to what all of the blue noise is across the spectrum. We discovered the other day that the external shell of the structure is metallic - we had assumed it was simply some form of non metallic structure! I can only perhaps guess that the noise we can see are reflections of the radio waves bouncing around internally?
Would welcome any opinions, suggestion on how to improve wifi in this area.
