With Cisco Mobility Express you can use a Cisco 1800/2800/3800 AP as controller. This is really neat, you dont need a WLC anymore. You will not get all functions a WLC have but the most common is implemented in "Mobility Express". For handling in Nedi I have just copied the def-file for Cisco 5508 controller and that seems to be okey
cp 1.3.6.1.4.1.9.1.1069.def 1.3.6.1.4.1.9.1.2370.def (2802 AP)
cp 1.3.6.1.4.1.9.1.1069.def 1.3.6.1.4.1.9.1.2371.def (1832 AP)
