The bare minimum requirement for approximating the X,Y coordinates of any wireless device is for it to be detected by at least three APs and located inside the perimeter boundaries of these APs. Generally, the more APs that are able to detect a device, the better the chances are of accurately. The answer, contrary to popular belief is not “It Depends”. The answer is very straightforward, easy to understand, and very sane: The correct number of APs for your design is the minimum number of APs required to meet your stated design criteria. This means, to have the most optimal (least waste). Even the top end Cisco LAP 11xx and 36xx series APs are rated at an absolute maximum of 100 users. To simultaneously support 800 users, I wouldn't use any less than 10 enterprise grade APs (not Linksys, not Cisco small business, but real enterprise APs), with an ideal number between 20-25 depending. As a guide, and ONLY AS A GUIDE, you calculate 20 metres radius. I strongly recommend you organize for a wireless site survey done. Placements of AP and/or how many AP may sound easy but there are so many things that can go wrong. 02-17-2013 01:55 AM If I want to use AP support 802.
