Rogue detection and counter

measures

AP radios automatically scan the RF spectrum for other devices transmitting in the same spectrum. The RF scans
discover third-party transmitters in addition to other Nortel radios. WSS Software considers the non-Nortel transmitters
to be devices of interest, which are potential rogues.
You can display information about the devices of interest. To identify friendly devices, such as non-Nortel access points
in your network or neighbor’s network, you can add them to the known devices list. You also can enable countermea-
sures to prevent clients from using the devices that truly are rogues.
With WLAN Management Software, you also can display the physical location of a rogue device. (For more informa-
tion, see the Nortel WLAN Management Software 2300 Series Reference Guide.)

About rogues and RF detection

RF detection detects all the IEEE 802.11 devices in a Mobility Domain and can single out the unauthorized rogue access
points.
