Channel Metrics

The channel metrics graph displays channel quality, availability, and utilization metrics as seen by a spectrum monitor or hybrid Instant AP. You can view the channel utilization data based on 2 GHzGigahertz. and 5 GHzGigahertz. radio channels. The percentage of each channel that is currently being used by Wi-FiWi-Fi is a technology that allows electronic devices to connect to a WLAN network, mainly using the 2.4 GHz and 5 GHz radio bands. Wi-Fi can apply to products that use any 802.11 standard. devices, and the percentage of each channel being used by non-Wi-FiWi-Fi is a technology that allows electronic devices to connect to a WLAN network, mainly using the 2.4 GHz and 5 GHz radio bands. Wi-Fi can apply to products that use any 802.11 standard. devices and 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. ACIAdjacent Channel Interference. ACI refers to interference or interruptions detected on a broadcasting channel, caused by too much power on an adjacent channel in the spectrum.. The graph shows the channel availability, the percentage of each channel that is available for use, and the current relative quality of selected channels in the 2.4 GHzGigahertz. or 5 GHzGigahertz. radio bandsBand refers to a specified range of frequencies of electromagnetic radiation.. To view the graphs, click 2.4 GHz or 5 GHz in the Access Point > Spectrum section of the dashboard. While spectrum monitors can display data for all channels in their selected bandBand refers to a specified range of frequencies of electromagnetic radiation., hybrid Instant APs display data for a single monitored channel.

Channel Metrics shows the information displayed in the Channel Metrics graph.

Description

Channel

A 2.4 GHzGigahertz. or 5 GHzGigahertz. radio channel.

Quality(%)

Current relative quality of selected channels in the 2.4 GHzGigahertz. or 5 GHzGigahertz. radio bandsBand refers to a specified range of frequencies of electromagnetic radiation., as determined by the percentage of packet retries, the current noise floor, and the duty cycle for non-Wi-FiWi-Fi is a technology that allows electronic devices to connect to a WLAN network, mainly using the 2.4 GHz and 5 GHz radio bands. Wi-Fi can apply to products that use any 802.11 standard. 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-FiWi-Fi is a technology that allows electronic devices to connect to a WLAN network, mainly using the 2.4 GHz and 5 GHz radio bands. Wi-Fi can apply to products that use any 802.11 standard. devices.

Interference Util(%)

The percentage of the channel currently being used by non-Wi-FiWi-Fi is a technology that allows electronic devices to connect to a WLAN network, mainly using the 2.4 GHz and 5 GHz radio bands. Wi-Fi can apply to products that use any 802.11 standard. interference plus Wi-FiWi-Fi is a technology that allows electronic devices to connect to a WLAN network, mainly using the 2.4 GHz and 5 GHz radio bands.
