In my work, We acquire an AIR-AP2802I-N-K9 by error some time ago, and this AP need a WLC to works properly. We has read in many blogs, that we can deploy the "Cisco 2800 Series Mobility Express" to converting a AP into a Mobility Express AP (to obtain all functionality that have AIR-AP2802I-N-K9C).
I include the ebook that I see as reference to do this process:
Conversion CAPWAP AP to a Mobility Express capable AP:

It's possible to deploy this change? or we need obligatory acquire a WLC or AP K9C to make this AP works?
I hope someone can help me.
