Interferer
Description
Frequency
Hopper (Xbox)
The Microsoft Xbox device uses a frequency hopping protocol in the 2.4 GHz band. These
devices are classified as Frequency Hopper (Xbox).
Frequency
Hopper (Other)
When the classifier detects a frequency hopper that does not fall into one of the above
categories, it is classified as Frequency Hopper (Other). Some examples include IEEE
802.11 FHSS devices, game consoles and cordless/hands-free devices that do not use one
of the known cordless phone protocols.
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).
There may be other equipment that behaves 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.
Channel Details
When you move your mouse over a channel, the channel details or the summary of the 5 GHz and 2.4 GHz
channels as detected by a spectrum monitor are displayed. You can view the aggregate data for each channel
seen by the spectrum monitor radio, including the maximum AP power, interference and the signal-to-noise-
and-interference Ratio (SNIR). SNIR is the ratio of signal strength to the combined levels of interference and
noise on that channel. Spectrum monitors display spectrum data seen on all channels in the selected band, and
hybrid APs display data from the one channel they are monitoring.
