Interesting pattern

I have found an interesting interference upon looking at my work wifi traffic, and although i dont use the chanalizer (you guys seriously should port it to nix, or at least invest a couple of people in adding the topographical view mode in EaKiu)

anyhow, i will ID this device, for now, i will post pictures and ask if anyone has seen anything like this...

basically normal chatter at the top, then the crazyness, then this weird device working, and after a minute of what you see at the bottom (you can probably see the pattern around channel 9), it was all gone, like nothing ever happened.

Off to identifying what this is :)
