Non-Wi-Fi Patterns
Microwave Ovens
Microwave Ovens operate in the 2.4 GHz range. Use
the Density View of Chanalyzer to identify microwave
oven leakage. Typically they create a sloping
mountain shape in the Density View. Since
microwaves are usually used from 1-5 minutes, it
helps to adjust the timespan to about two minutes.
Interference occurs when the microwave oven
transmits on the same frequencies as the Wi-Fi
channel. In this image, you can see how the
mountain-shaped microwave oven covers the
curvature of the Wi-Fi on channel 11.
The amplitude levels of the microwave vary
depending on the distance it is from the spectrum
analyzer. Experiment with a microwave oven and
varying locations.
Another great way to identify microwave oven
interference is using the Waterfall View. The waterfall
view shows how long something caused RF activity.
