WLC Best Practices/general questions

I'm a beginner with wireless and, even more so, the WLC. (I'm using an WLC module in a 2851 ISR). I have a couple general questions regarding the WLCM:

1) I will be deploying five LAPs off of the WLCM in one floor of one building. Is it true I will not have to worry about overlapping channels as the WLCM will detect contention and change channels? Do I not have to configure anything in particular, regarding channels, on the RF side?

2) I will also be using 7920s in my deployment and want to ensure call quality when a user walks/roams between LAPs. I will be using static WEPs and 7920s reside on the same VLAN. Since all APs are associated to the same WLCM, is it true I will not have to do any additional configuration to ensure smooth roaming?

Re: WLC Best Practices/general questions

You are correct on both questions. The RRM (Radio Resource Management) algorithms will automatically choose the best channel assignments for the Access Points (based on interference from other 802.11 devices and noise from non-802.11 devices on the same frequency) and the transmit power (based on how many neighboring APs are seen). Roaming will all be transparrant, the controller will just move the clients/phones from old AP to the new one.
