An AIR-SAP2602-x-K9 with lightweight IOS and a CAP2602-x-K9, what’s the difference? I have 3 pieces of AIR-SAP2602-x-K9 and no WLC, and I need an AP. Shall I buy another AIR-SAP2602-x-K9 or should I wait and buy AIR-CAP after I buy the WLC?
More questions: Can the SAP series be upgradable to CAP? Anyone get an access to the WLC he will not be able to reach and change the configuration of SAP AP’s?
Well, actually, the standalone model doesn’t support features the WLC support like RRM and CleanAir for example. So if you want these features, you need the AIR-CAP and a WLC. Using a WLC centrally manages the wireless as far as configuration and images. SAP or standalone, requires you to manage each access point. This means the configuration and software image. Time is saved using a WLC and also the features you get with a WLC doesn’t compare to what you can get with a SAP.
Can a CAP be converted into a SAP??? Yes, it is easy way for you to convert back and forth. You can read this Using a TFTP Server to Return to a Previous Release…

How to Convert Cisco a Lightweight AP to an Autonomous AP?
Cisco APs are categorized into the Lightweight AP (LAP) and the Autonomous AP (AP). The LAP operates with a Wireless LAN Controller (WLC); otherwise the AP works on its own. APs can convert into the other mode for the purpose of use.
