We are deploying a new office and exploring the options for WLAN deployment. We were pretty impressed with 3500 series APs and that it supports CleanAir.
However, we have decided to go for standalone AP deployment model now. As 3500 does not work in standalone mode, so we are looking for APs that can work in standalone mode ( and later can be converted to lightweight if needed). We can go for 1140 in that case. However, it would be better for us to know the main differences between features supported by 3500 lightweight AP and 1140 standalone AP. CleanAir looks like the main one. Are there other important ones as well?
