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.
