Parameter Description
microwave-inverter
View information for inverter microwave devices seen by the spectrum
device.
NOTE: This option is available only for 2.4 GHz spectrum devices.
video
View information for video devices seen by the spectrum device.
xbox
View information for Xbox devices seen by the spectrum device.
NOTE: This option is available only for 2.4 GHz spectrum devices.
Usage Guidelines
Use this command to view channel, signal and duty-cycle information and add/delete times for the last 256
devices seen by a spectrum monitor or hybrid AP.
Non-Wi-Fi Interferers
The following table describes each type of non-Wi-Fi interferer detected by a spectrum monitor or hybrid AP.
Note also that a hybrid AP on a 20 MHz channel will see 40 MHz Wi-Fi data as non-Wi-Fi data.

Interferer
Type
Description
Bluetooth Any device that uses the Bluetooth protocol to communicate in the 2.4 GHz band is
classified as a Bluetooth device. Bluetooth uses a frequency hopping protocol.
Fixed
Frequency
(Audio)
Some audio devices such as wireless speakers and microphones also use fixed
frequency to continuously transmit audio. These devices are classified as Fixed
Frequency (Audio).
Fixed
Frequency
(Cordless
Phones)
Some cordless phones use a fixed frequency to transmit data (much like the fixed
frequency video devices). These devices are classified as Fixed Frequency (Cordless
Phones).
Fixed
Frequency
(Video)
Video transmitters that continuously transmit video on a single frequency are classified
as Fixed Frequency (Video). These devices typically have close to a 100% duty cycle. These
types of devices may be used for video surveillance, TV or other video distribution, and
similar applications.
Fixed
Frequency
(Other)
All other fixed frequency devices that do not fall into one of the above categories are
classified as Fixed Frequency (Other). Note that the RF signatures of the fixed frequency
audio, video and cordless phone devices are very similar and that some of these devices
may be occasionally classified as Fixed Frequency (Other).
Frequency
Hopper
(Cordless
Base)
Frequency hopping cordless phone base units transmit periodic beacon-like frames at all
times. When the handsets are not transmitting (i.e., no active phone calls), the cordless
base is classified as Frequency Hopper (Cordless Base).
