How Many Beacons Do You Need?

I'm trying to get a sense of how many beacons do you need given that you have geomagnetic. So if I add geomagnetic and I'm in an environment like a department store or a shopping center, but I really want optimal location positioning then what's the kind of the density of beacons that your teams would typically recommend? Our typical recommendation perhaps would be to have a beacon, at least as a starting point per 200 square meters,. Depending on the environment, it can be less, it canBeacon planner provides a reference plans for your location.
