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.

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.

Description

Channel

A 2.4 GHz or 5 GHz radio channel.

Quality (%)

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.

Availability (%)

The percentage of the channel currently available for use.

Utilization (%)

The percentage of the channel being used.

WiFi Util (%)

The percentage of the channel currently being used by Wi-Fi devices.

Interference Util (%)

The percentage of the channel currently being used by non-Wi-Fi interf Wi-Fi ACI
