Radar provides a list of APs organized in categories based on the scan results of the Analysis Engine. Radar will try to assign each discovered AP to one of these categories. If it can't find a specific category for the AP, it will assign it to the Uncategorized APs category. Uncategorized APs require manual classification. To get the best protection from Radar, classify uncategorized APs as soon as possible.
You can manually assign APs from one category to another using Radar. For more information, see Reclassifying APs.
