    Default 2.4 recording inside Hydro Electric Plant -

    Hello All,

    I recently conducted a SA Survey at a Hydro Electric Power Plant and this is one of the 2.4 recordings. I believe the noise in waterfall is harmonic resonance from the generators. Pretty cool huh?

    Do you think this will affect 802.11bg? I don't think it will becuase the levels sem so low but I would appreciate your feedback!

    seems to be normal, in any environment i see same blue background, maybe trying whit a large usb cable to put some distance between wi-spy and laptop to discard laptop electronics generating that activity

    I'm inclined to agree. Blue spikes indicate less than 10 percent utilization, so that is probably your wireless card beaconing. Those generators must be shielded very well!
