Non-Wi-FiInterferer Description
Bluetooth Anydevice that uses the Bluetoothprotocol to comm unicate in the 2.4GHz band is classified as a

Bluetooth

device. Bluetoothuses a frequency hopping protocol.
FixedFrequency
(Audio)
Some audio devices such asw ireless speakersand microphones also use fixed frequency to
continuouslytransmit audio. These devices are classified as

FixedFrequency (Audio)

.
FixedFrequency
(CordlessPhones)
Some cordless phonesuse a fixed frequency to transmit data (much like the fixed frequencyvideo
devices).These devices are cl assified as

FixedFrequency (Cordless Phones)

.
FixedFrequency
(Video)
Video transmittersthat continuously transmit video on a single frequency are classified as

Fixed

Frequency(Video

).These devices typicall y have close to a 100%duty cycle. These typesof devices m ay
beused for video surveillance, TV or other video distribution, and similar applications.
FixedFrequency
(Other)
All otherfixed frequency devices that do not fall into one of the abovecategories are classified as

Fixed

Frequency(Other

).Note that the RF signatures of thefixed frequency audio, video and cordl essphone
devicesare very simi lar and that some of these devices may be occasionally classified as Fixed
Frequency(Other).
FrequencyHopper
(CordlessBase)
Frequencyhopping cordless phone base units transmit periodic beacon-like frames at all times. When
thehandsets are not transmitting (i.e., no active phone calls), the cordless base is classified as

FrequencyHopper (Cordless Base

).
FrequencyHopper
(Cordless
Network)
Whenthere i san active phone call and one or more handsets are part ofthe phone conversation, the
devicei s classified as

FrequencyHopper (Cordless Network

).Cordl ess phones may operate in 2.4 GHz
or5 GHz bands. Some phones use both 2.4 GHz and 5 GHz bands (for example, 5 GHz for Base-to-
handsetand 2.4 GHz for Handset-to-base). These phones may be classified as unique Frequency Hopper
deviceson both bands.
FrequencyHopper
(Xbox)
TheMi crosoftXbox device uses a frequency hopping protocol in the 2.4 GHz band. These devices are
classifiedas

FrequencyHopper (Xbox

).
FrequencyHopper
(Other)
Whenthe classifier detects a frequency hopper that does notfall into one of the abovecategories, it is
classifiedas Frequency Hopper (Other). Some exampl es include IEEE 802.11 FHSS devices, game
consolesand cordless/hands-free devices that do notuse one of the known cordless phone protocols.
Microwave Common residential microwave ovens with a single magnetron are classified as a

Microwave

. These
typesof microwave ovens may be used in cafeterias, break rooms, dormitories and similar
environments.S ome industrial, healthcare or manufacturing environments may also have other
equipment thatbehave like a mi crowave and may also be classified asa Mi crowave device.
Microwave
(Inverter)
Some newer-model microwave ovens have the inverter technology tocontrol the power output and
thesemicrow aveovens may have a duty cycle close to 100%.These mi crowave ovensare classified as

Microwave (Inverter)

. Dual-magnetron industrial microwave ovens with higher duty cycle may also be
classifiedas Microw ave(Inverter). As in the Microwave category described above, there may be other
equipment thatbehave like inverter microw avesin some i ndustrial, healthcare or manufacturing
environments.Those devices may also be classified as Microwave (Inverter).
GenericInterferer Anynon-frequency hopping device that does not fall into one of the othercategories described in this
tablei s classified as a

GenericInterferer

. Forexampl e a Microwave-like device that doesnot operate in
theknown operating frequencies used by the Microwave ovens may be classified as a Generic
Interferer.Sim ilarly wide-band interfering devices may be classified as Generic Interferers.
