Wireless Coverage SLE (Application)
Use the Wireless Coverage SLE to assess your users' experiences with signal strength.
When the Wireless Coverage threshold is not met, Juniper Mist sorts the affected Zoom or Teams user minutes into classifiers.
What Does the Wireless Coverage SLE Measure?
Juniper Mist tracks active clients' Received Signal Strength Indicator (RSSI), as measured by the access point for the duration of the Zoom or Teams call. A low RSSI impacts the quality of the audio or video during a Zoom or Teams call. You can use this SLE to determine if you have sufficient access points.
Classifiers
When the RSSI threshold for a Zoom or Teams user minute is less than MOS 3.0, Juniper Mist sorts the issues into classifiers. The classifiers appear on the right side of the SLE block. In this example, 85 percent of issues were attributed to Weak Signal and 15 percent to Asymmetry Uplink. (See the classifier descriptions below the example.) You can expand the section further to view the details such as the statistics, affected users, and impacted locations.
-
Weak Signal—Clients received a weak signal due to other factors.
-
Asymmetry Downlink—Clients received a weak signal due to asymmetric downlink transmission strength between the AP and a client device. (The traffic going from the AP to the client is called downlink traffic.)
-
Asymmetry Uplink—Clients received a weak signal due to asymmetric uplink strength between the AP and the client device. (Uplink traffic is the traffic going from the client to the AP, and then to the Internet.) Asymmetry can occur for various reasons, such as clients being too far from the AP.
