Re: how to scan for AP signal with spectrum analyzer
well, I'm sitting in a motel room, not a colo room, in a small town and I see the peak hold signals in my hotel room filling in across the chart at -35db!! from 5755 to 5810. There are no holes. So the noise floor is -35db in my motel room across the whole spectrum. In peak mode there is a flat line created right across the spectrum.
I get 2.5mhz blips popping up across the band moving all over the place. They pop up and disppear on all frequencies raising the peak hold to a flat line at -35. I don't see any change in the signals when I unplug the MT power. These signals are SO strong though. As far as I know there isn't anything else around here. The 2.4 signals are zero. There are none at all except for the AP I talk to for this link. No other 2.4 blips at all. Then I go to test this MT AP and the entire band is full of signals. I have a 5 inch whip on the SA and I can stick the unit in the bathroom and close the door and the signals are just as strong. I'm not sure what the heck I am seeing. At -35dbm, I don't even know for sure that the MT is working because they are scanning across the band so fast I really can't tell if turning off the MT is changing anything. It's kinda weird. I'm use to seeing those 20mhz channels. Not the entire band having a peak of -35db. There are some strong signals here and I can't figure this out. This is a mom & pop old budget motel. They don't have any electronics. At least the TV works. |
