We have a small wireless network with four IOS-based 1220B. We are planning to upgrade them all to G modules, convert to Lightweight APs, and manage them with a small WLC like the 2106.
Currently we have a corporate Vlan and aguest vlan on these APs, using 802.1x MS PEAP for authentication to our Active Directory via a MS radius server.
I have done some reading and talking to sales reps but still not completely sure if the upgrade will meet the following needs:
1. automatic RF channel and power mgmt without having to buy additional Cisco components like WCS. One of the APs is in a different building.
2. basic RF monitoring and diagnostics
3. basic location identification of clients and APs.
4. easy client setup for guest authentication (via web) and easier client setup than MS PEAP for corporate user authentication, on the same controller.
5. the 2106 and some of the higher-end controllers only have 100mps uplink. With 20-30 wireless-G users in a training room they could overwhelm a single WLC setup. The fat-client setup doesn't have a bottleneck like this.
I understand if you throw money at it, you can add more controllers and spread the users out. But that kind of defeats the benefit of having a centralized controller to manage everything, unless you pay big bucks for WCS.
Can someone pardon my ignorance and shed some light on these issues?
