RF Scan View

The RF Management RF Scan View Screen is used to view Scanning Mode data for APs. Wireless networks operate in environments with electrical and radio frequency devices that can interfere with network communications. APs can examine the radio frequency environment in which the Wi-Fi network is operating, identify interference, and classify its sources. An analysis of the results can then be used to quickly isolate issues with packet transmission, channel quality, and traffic congestion caused by contention with other devices operating in the same band or channel.

Note: To view Scanning Mode data for an AP, the AP must be in "Scanning Mode". If necessary, go to the Access Points Screen (Network - AP Registration - Access Points), select the AP, click on the Edit icon and select Edit Dedicated Scanning Mode. Note that when an AP is in Scanning Mode, no clients can associate with the AP.

Viewing Scanning Mode Data

Click on the Select Device button and select an AP. The "real time" Scanning Mode data for the AP will be displayed. Repeat to view data on other APs. You can only view data for one AP at a time.

Click on the Show History Data button to display historical data. In the historical data display, you can view data by Band (2.4G, 5G), Channel Width (20MHz, 40MHz), Channel, and Time Period (last 24 hours, 3 days, 7 days).

Scanning Mode Data

By default, "real time" data is displayed. Click on the Show History Data button to display historical data.

Real Time Data

By default, OmniVista Cirrus displays "real time" data for the selected AP for both the 2.4G and 5G Bands. Hover the mouse over a data point for more detailed data.

• Radio - The wireless band of the network
• Utilization - The percentage of the channel being used.
• Channel Width - The width of the channel
• Frequency Range - The frequency range of the channel.
• Noise - Noise is the measure of the wireless signal created from the sum of all the noise sources and unwanted signals.
• Known APs - The number of valid APs identified on the channel.
• Unknown APs - The number of interfering or rogue APs identified on the channel.

Historical Data

Click on the Show History Data button to display historical data. In the historical data display, you can view data by Band (e.g., 2.4G, 5G), Channel Width (e.g., 20MHz, 40MHz), Channel, and Time Period (last 24 hours, 3 days, 7 days).
