Non-Wi-Fi Interferer Type Frequency Hopper (Cordless Network) Description 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. Microwave Common residential microwave ovens with a single magnetron are classified as a Microwave. These types of microwave ovens may be used in cafeterias, break rooms, dormitories and similar environments. Some industrial, healthcare or manufacturing environments may also have other equipment that behave like a microwave and may also be classified as a Microwave device. Microwave (Inverter) Some newer-model microwave ovens have the inverter technology to control the power output and these microwave ovens may have a duty cycle close to 100%. These microwave ovens are classified as Microwave (Inverter). Dual-magnetron industrial microwave ovens with higher duty cycle may also be classified as Microwave (Inverter). As in the Microwave category described above, there may be other equipment that behave like inverter microwaves in some industrial, healthcare or manufacturing environments. Those devices may also be classified as Microwave (Inverter). Generic Interferer Any non-frequency hopping device that does not fall into one of the other categories described in this table is classified as a Generic Interferer. For example a Microwave-like device that does not operate in the known operating frequencies used by the Microwave ovens may be classified as a Generic Interferer. Similarly wide-band interfering devices may be classified as Generic Interferers.
