My office is moving to a new a location where the previous tenant left a lot of Cisco Air-Cap26021-A-K9 APs for us to grab if we wanted to, they left no controller however. My question is: can they be used as stand alone APs? from what i've read i don't think they can but i'm just making sure. Also, would it be possible for us to buy a controller to configure the units? I haven't worked with Cisco wireless gear before so i'm not sure if: 1. it's possible, 2. cost effective, meaning, do we need licenses for the AP and the controller?. 3. is it worth, the see they are 802.11n and we are using ac at the other place with stand alone APs. 4. Are they still supported? don't want to make any investment in it if Cisco does not provide any type of support any longer for this product.
Thanks in advanced.
