I’d like to suggest that you see the cloud service from D-Link and Tanaza.com.
There are many things that are very useful. For example, a MAP of the world showing where APs are installed, with the possibility of uploading a building plan in .PDF and with that create the possibility of putting the respective AP in the right place, collecting the information of the AP by the place . It is also useful for if the AP is broken or disconnected, to know where it is locally. This happens also with the information of the APs in the world map.
