Thanks Steve for your interest. In the examples above, presence was used for the A/B testing while location was used for the high traffic example. The number of APs is very much a function of the venue and each site has its own needs. Presence can be deployed with as few as one AP. However, location requires at least three APs. In general, we recommend one AP per 5000 sq ft for basic presence/location with an increase to one AP per 2500 sq feet for enhanced location accuracy. In general, the more access points, the higher the level of location accuracy.
