Channel Details

When you move the mouse over a channel, the channel details or the summary of the 2.4 GHzGigahertz. and 5 GHzGigahertz. channels as detected by a spectrum monitor are displayed. You can view the aggregate data for each channel seen by the spectrum monitor radio, including the maximum Instant AP power, interference, and the SNIRSignal-to-Noise-Plus-Interference Ratio. SNIR refers to the power of a central signal of interest divided by the sum of the interference power and the power of the background noise. SINR is defined as the power of a certain signal of interest divided by the sum of the interference power (from all the other interfering signals) and the power of some background noise. . The SNIRSignal-to-Noise-Plus-Interference Ratio. SNIR refers to the power of a central signal of interest divided by the sum of the interference power and the power of the background noise. SINR is defined as the power of a certain signal of interest divided by the sum of the interference power (from all the other interfering signals) and the power of some background noise. is the ratio of signal strength to the combined levels of interference and noise on that channel. Spectrum monitors display spectrum data of all channels in the selected bandBand refers to a specified range of frequencies of electromagnetic radiation., and hybrid Instant APs display data for the channel they are monitoring.

Channel Details Information shows the information that you can view in the Channel Details graph.

Table 1: Channel Details Information
Column	Description
Channel	An 802.11a802.11a provides specifications for wireless systems. Networks using 802.11a operate at radio frequencies in the 5 GHz band. The specification uses a modulation scheme known as orthogonal frequency-division multiplexing (OFDM) that is especially well suited to use in office settings. The maximum data transfer rate is 54 Mbps. or 802.11g802.11g offers transmission over relatively short distances at up to 54 Mbps, compared with the 11 Mbps theoretical maximum of 802.11b standard. 802.11g employs Orthogonal Frequency Division Multiplexing (OFDM), the modulation scheme used in 802.11a, to obtain higher data speed. Computers or terminals set up for 802.11g can fall back to speed of 11 Mbps, so that 802.11b and 802.11g devices can be compatible within a single network. 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-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.
Type	Device type.
Total nonwifi (%)	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. devices.
Known Instant APs	Number of valid Instant APs identified on the radio channel.
UnKnown Instant APs	Number of invalid or rogue Instant APs identified on the radio channel.
Channel Util (%)	Percentage of the channel currently in use.
Max Instant AP Signal (dBm)	Signal strength of the Instant AP that has the maximum signal strength on a channel.
Max Interference(dBm)	Signal strength of the 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. 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.
