Type
Description
Microwave Common residential microwave ovens with a single magnetron are classified as a
Microwave. These types of microwave ovens may be used in cafeterias, break rooms,
dormitories and similar environments. Some industrial, healthcare or manufacturing
environments may also have other equipment that behave like a microwave and may also
be classified as a Microwave device.
Microwave
(Inverter)
Some newer-model microwave ovens have the inverter technology to control the power
output and these microwave ovens may have a duty cycle close to 100%. These
microwave ovens are classified as Microwave (Inverter). Dual-magnetron industrial
microwave ovens with higher duty cycle may also be classified as Microwave (Inverter). As
in the Microwave category described above, there may be other equipment that behave
like inverter microwaves in some industrial, healthcare or manufacturing environments.
Those devices may also be classified as Microwave (Inverter).
Generic
Interferer
Any non-frequency hopping device that does not fall into one of the other categories
described in this table is classified as a Generic Interferer. For example a Microwave-like
device that does not operate in the known operating frequencies used by the Microwave
ovens may be classified as a Generic Interferer. Similarly wide-band interfering devices
may be classified as Generic Interferers.
Example
The output of this example shows details for fixed-frequency video devices seen by a spectrum monitor or
hybrid AP radio.
