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 Base).
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.
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.
