Abstract
Techniques are described that detect areas with insufficient radio frequency (RF) coverage in a wireless network. A network management system (NMS) determines one or more service level expectation (SLE) metrics for each client device in a wireless network. The SLE metrics are aggregated to each access point (AP) in the wireless network, and each AP is assigned an AP score based on the aggregated SLE metrics. To identify potential coverage holes, the NMS groups APs having poor AP scores. If a root cause of the poor AP scores cannot be automatically resolved and if the poor AP scores persist for a predetermined period of time, the group of APs is determined to represent a true coverage hole. The NMS may generate a notification regarding recommended corrective actions to the customer and/or IT personnel.
