Coverage Holes Identified
The insight can be accessed only at the context. This insight determines the connection status of Wi-Fi Wi-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. clients with the APs due to poor Wi-Fi coverage. Machine learning determines when a relatively large proportion of the client minutes that consistently have low SNR Signal-to-Noise Ratio. SNR is used for comparing the level of a desired signal with the level of background noise. links. The exact location of the coverage hole can be identified from the location of the clients listed with poor coverage and implies that there is a need to deploy one more AP which will avoid the low SNR clients in the network. is categorized under wireless quality since the clients in coverage holes have poor or intermittent Wi-Fi connectivity causing loss of productivity.
Insight Summary
The insight summary provides the following details:
- —Displays the possible causes for which the clients experience poor Wi-Fi coverage in the network.
- —Displays the recommendation against each failure to resolve the same.
- Failures—Displays the exact number and percentage of failures that occurred against each failure reason.

Site
Lists the sites where the clients experience poor Wi-Fi coverage in the network. Click the arrow 
to view the pictorial graph of the sites.
Click the number displayed on the card, to view a detailed description of the impacted sites:
- —Name of the site impacted by the insight and link to the specific insight at the site context.
- —Number of clients that experience coverage hole in each site.
- —Total number clients that need to be deployed in the network due to coverage holes.
Access Point
Lists the number and details of APs which have clients with poor connections due to a coverage hole in the network. This is measured by the amount of time the client experiences poor vs good connectivity. Click the arrow to view the pictorial graph of the access points. Click the drop-down list to view the following:
- Most Impacted by Low Uplink SNR—Pictorial graph of APs impacted maximum by low uplink SNR.
- Most Impacted by Low 5 GHz Gigahertz. Downlink SNR—Pictorial graph of APs impacted maximum by low 5 GHz downlink SNR.
- Most Impacted by Low 2.4 GHz Downlink SNR—Pictorial graph of APs impacted maximum by low 2.4 GHz downlink SNR.
Click the number displayed on the card, to view a detailed description of the impacted access points:

- Impacted (Time)—Time range of the coverage hole detected in each AP.
- Clients—Number of clients with poor Wi-Fi coverage in each AP.
- Coverage Hole Type—The type of coverage hole detected in each AP.
- —Serial number of each AP.
- —Version of the firmware running on each AP.
- —Model number of each AP.
Client
Lists the MAC Address, name, host name, auth ID, and the number of connected clients affected by poor connections determined by the total number of minutes spend in the coverage hole. Click the arrow to view the pictorial graph of the clients. Click the drop-down list to view the following:
- Low Uplink SNR Minutes—Pictorial graph of clients impacted maximum by low uplink SNR minutes.
- Low 5 GHz Downlink SNR—Pictorial graph of clients impacted maximum by low 5 GHz downlink SNR.
