You have 4 access points in a building and they work great with a wireless controller. The range is very good and so far in 6 months none of them have had to be dropped. I'm not sure how many devices are connected, but I'm thinking 10-12 devices per access point so they don't get overloaded. If you're looking for a quality, business-class access point, get it. They also come with ceiling tile grid brackets for easy installation.
