Non-Wi-Fi
Interferer
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 inverter technology to control the power
output and 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.
Understanding the Spectrum Analysis Session Log
The spectrum analysis Session Log tab displays times the spectrum monitors and hybrid APs connected to or
disconnected from the spectrum client during the current browser session. This tab also shows changes in a
hybrid AP’s scanning channel caused by changes to the hybrid AP’s 802.11a or 802.11g radio profile or
automatic channel changes by the DFS or ARM features. The latest entry in the session log is also displayed in a
footer at the bottom of the Spectrum Monitors and Spectrum Dashboard window. When you close the
browser and end your spectrum analysis session, the session log is cleared.
The example in Figure 134 shows that a 2.4 GHz radio on hybrid AP was connected to the spectrum analysis
client, its channel changed twice, then was disconnected from the spectrum client.
