Unknown 5Ghz shape

Hi Joel,

Last night I decided to randomly scan my home environment and noticed a 5Ghz shape that does not look common. I was wondering if you can help identify this. Please see shared screenshots and .wsx file. Thanks!

That's a bit "rougher" of a shape than usual, but it does have the look of an OFDM (802.11a), HT-OFDM (802.11n), or VHT-OFDM (802.11ac) signature. The top just isn't as flat as usual, but it's the right width. Wi-Fi signatures do vary quite a bit, my guess is that it's due to different transmitters just being different transmitters.

I hope that helps, thanks!
