Analysis Engine Overview
The Analysis engine relies on a database of known devices on the Summit WM Controller, Access
Points and Software system. The Analysis engine compares the data from the RF Data Collector with
the database of known devices.
This database includes the following:
● Wireless APs – Registered with any Summit WM Controller with its RF Data Collector enabled and
associated with the Analysis Engine on this Summit WM Controller.
● Third-party APs – Defined and assigned to a WM-AD.
● Friendly APs – A list created in the Summit WM series Spy user interface as potential rogue access
points are designated by the administrator as Friendly.
