Any device that uses the Bluetooth protocol to communicate in the 2.4 GHzGigahertz. bandBand refers to a specified range of frequencies of electromagnetic radiation. is classified as a Bluetooth device. Bluetooth uses a frequency hopping protocol.

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).

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).

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.

All other fixed frequency devices that do not fall into any of the above categories are classified as Fixed Frequency (Other).

Note that the RFRadio Frequency. RF refers to the electromagnetic wave frequencies within a range of 3 kHz to 300 GHz, including the frequencies used for communications or Radar signals. 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 hopping cordless phone base units transmit periodic beacon-like frames at all times. When the handsets are not transmitting (that is, when there are no active phone calls), the cordless base is classified as Frequency Hopper (Cordless Base).

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 GHzGigahertz. or 5 GHzGigahertz. bandsBand refers to a specified range of frequencies of electromagnetic radiation.. Some phones use both 2.4 GHzGigahertz. and 5 GHzGigahertz. bandsBand refers to a specified range of frequencies of electromagnetic radiation. (for example, 5 GHzGigahertz. for Base-to-handset and 2.4 GHzGigahertz. for Handset-to-base). These phones may be classified as unique Frequency Hopper devices on both bandsBand refers to a specified range of frequencies of electromagnetic radiation..

The Microsoft Xbox device uses a frequency hopping protocol in the 2.4 GHzGigahertz. bandBand refers to a specified range of frequencies of electromagnetic radiation.. These devices are classified as Frequency Hopper (Xbox).

When the classifier detects a frequency hopper that does not fall into any of the prior categories, it is classified as Frequency Hopper (Other). Some examples include IEEEInstitute of Electrical and Electronics Engineers. 802.11802.11 is an evolving family of specifications for wireless LANs developed by a working group of the Institute of Electrical and Electronics Engineers (IEEE). 802.11 standards use the Ethernet protocol and Carrier Sense Multiple Access with collision avoidance (CSMA/CA) for path sharing. FHSSFrequency Hopping Spread Spectrum. FHSS is transmission technique that allows modulation and transmission of a data signal by rapidly switching a carrier among many frequency channels in a random but predictable sequence.
