Table 16 Non-Wi-Fi Interferer Types Non-Wi-Fi Interferer Description Microwave (Inverter) Generic Interferer 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). 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. Channel Metrics The channel metrics graph displays channel quality, availability and utilization metrics as seen by a spectrum monitor or hybrid AP. You can view the channel utilization data for the percentage of each channel that is currently being used by Wi-Fi devices, and the percentage of each channel being used by non-Wi-Fi devices and 802.11 adjacent channel interference (ACI). This chart shows the channel availability, the percentage of each channel that is available for use, or the current relative quality of selected channels in the 2.4 GHz or 5 GHz radio bands. While spectrum monitors can display data for all channels in their selected band, hybrid APs display data for their one monitored channel only. To view this graph, click 2.4 GHz in the Spectrum section of the dashboard. Figure 92 Channel Metrics for the 2.4 GHz Radio Channel Table 17 shows the information displayed in the channel metrics graph. Table 17 Channel Metrics Column Description Channel Quality (%) Availability (%) Utilization (%) WiFi Util (%) Interference Util (%) A 2.4 GHz or 5 GHz radio channel. Current relative quality of selected channels in the 2.4 GHz or 5 GHz radio bands, as determined by the percentage of packet retries, the current noise floor, and the duty cycle for non-Wi-Fi devices on that channel. The percentage of the channel currently available for use. The percentage of the channel being used. The percentage of the channel currently being used by Wi-Fi devices. The percentage of the channel currently being used by non-Wi-Fi interference + Wi-Fi ACI (Adjacent Channel Interference) 102 | Spectrum Monitor Dell PowerConnect W-Series Instant Access Point 6.1.3.4-3.1.0.0 | User Guide
