Figure 103 Channel Details Channel Details Information shows the information that you can view in the channel details graph. Table 64: Channel Details Information Column Description Channel An 802.11a or 802.11g radio channel. Quality(%) Current relative quality of the channel. Utilization(%) The percentage of the channel being used. Wi-Fi (%) The percentage of the channel currently being used by Wi-Fi devices. Type Device type. Total nonwifi (%) The percentage of the channel currently being used by non Wi-Fi devices. Known APs Number of valid APs identified on the radio channel. UnKnown APs Number of invalid or rogue APs identified on the radio channel. Channel Util (%) Percentage of the channel currently in use. Max AP Signal (dBm) Signal strength of the AP that has the maximum signal strength on a channel. Max Interference (dBm) Signal strength of the non Wi-Fi device that has the highest signal strength. SNIR (db) The ratio of signal strength to the combined levels of interference and noise on that channel. This value is calculated by determining the maximum noise-floor and interference-signal levels, and then calculating how strong the desired signal is above this maximum. 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.

Channel Details Information
shows the information that you can view in the channel details graph.
Column
Description
Channel
An 802.11a or 802.11g radio channel.
Quality(%)
Current relative quality of the channel.
Utilization(%)
The percentage of the channel being used.
Wi-Fi (%)
The percentage of the channel currently being used by Wi-Fi devices.
Type
Device type.
Total nonwifi (%)
The percentage of the channel currently being used by non Wi-Fi devices.
Known APs
Number of valid APs identified on the radio channel.
UnKnown APs
Number of invalid or rogue APs identified on the radio channel.
Channel Util (%)
Percentage of the channel currently in use.
Max AP Signal (dBm)
Signal strength of the AP that has the maximum signal strength on a channel.
Max Interference
(dBm)
Signal strength of the non Wi-Fi device that has the highest signal strength.
SNIR (db)
The ratio of signal strength to the combined levels of interference and noise on that
channel. This value is calculated by determining the maximum noise-floor and
interference-signal levels, and then calculating how strong the desired signal is
above this maximum.

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.
