A read-only CWirelessNotificationCategory value classifying the broad category of the network condition that triggered this notification. This lets a management console group and filter incoming notifications, such as separating security-related alerts from performance-related ones, without parsing free-text descriptions. For example, a rogue-AP detection alert and a coverage-hole alert would likely carry different cWNotificationCategory values, letting an admin filter a dashboard down to just security-category events.
