Column Duty-cycle Add-time Update-time Description Device duty cycle. This value represents the percent of time the device broadcasts a signal. Time at which the device was first detected. Time at which the device's status was updated. Non Wi-Fi Interferers The following table describes each type of non Wi-Fi interferer detected by the spectrum monitor feature. Table 63: Non Wi-Fi Interferer Types Non Wi-Fi Interferer 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 Bas). Frequency Hopper (Cordless Network) When there is an active phone call and one or more handsets are part of the phone conversation, the device is classified as Frequency Hopper (Cordless Network). Cordless phones may operate in 2.4 GHz or 5 GHz bands. Some phones use both 2.4 GHz and 5 GHz bands (for example, 5 GHz for Base-to-handset and 2.4 GHz for Handset-to-base). These phones may be classified as unique Frequency Hopper devices on both bands. Dell Networking W-Series Instant 6.4.3.1-4.2.0.0 | User Guide Spectrum Monitor | 334

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

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)

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 Bas)
.
Frequency
Hopper
(Cordless
Network)
When there is an active phone call and one or more handsets are part of the phone
conversation, the device is classified as
Frequency Hopper (Cordless Network)
. Cordless
phones may operate in 2.4 GHz or 5 GHz bands. Some phones use both 2.4 GHz and 5
GHz bands (for example, 5 GHz for Base-to-handset and 2.4 GHz for Handset-to-base).
These phones may be classified as unique Frequency Hopper devices on both bands.
