While reviewing the Service Level Expectations (SLEs) for your site, you notice a significantly high percentage of Asymmetry Uplink errors.
What do these errors indicate?
Asymmetry Uplink is a classifier under the Wireless Coverage SLE. It tracks the user minutes during which a client experiences poor coverage caused by a mismatch in transmit power between the access point and the client device. Because APs typically transmit at higher power than client devices, if the AP's power is set too high relative to the client, the AP may not be able to hear the client's weaker uplink signal, even though the client can hear the AP clearly on the downlink. This power asymmetry situation is classified as a coverage problem, since it results in the client experiencing an effective coverage hole for reliable two-way communication despite seemingly adequate downlink signal strength.
