Troubleshooting Spectral measurements
The following are some common interferences that could show up in a spectral measurement.
Microwave ovens can interfere with an 802.11 signal. They are most prevalent in channels 10 and 11. If possible, it is a good idea
to look at the spectral response while the microwave is running to determine it’s impact.
Bluetooth devices appear as spikes and appear to “roll” through the spectral view. They are fast moving and you may only see
them occasionally. The systems are designed to be inter-operable, but Bluetooth will impact throughput.
Channels can “bleed over” into adjacent channels. The width of the signal (due to RF considerations) can affect nearby channels,
as shown in
. This bleed over is treated as noise.
