The number of APs per location depends on the square footage as well as the structure of the building. For a normal single-level office layout with drywall and wood, we typically recommend 1 AP for a max of about 2000 sq. ft, or 25 devices, whichever is lower. For a building that uses masonry or has multiple levels, the number of APs would increase to provide adequate coverage. Unfortunately the nature of Wi-Fi is that it's impossible to predict exactly how many APs will be required without a site survey, which is rather time-consuming. However, we've worked with partners in the past to provide guidance and recommendations that have (for the most part) been fairly good.

The optimal separation between APs for an open-plan office with drywall is usually about 20-30 feet between APs, but again this depends on the density of client devices and the material of the walls. Sometimes we've suggested using outdoor APs inside large offices or warehouses because our outdoor APs are more powerful and have high gain antennas.
