comment Is there a limit to how many separate wifi networks can successfully and securely operate within a given (building) area without interference issues?
This takes care of interference problems, since in such setups lightweight access points would be aware of eachothers's signal and using the control point can be adjusted to reduce their own transmit power so that the interference is minimized. If you have a large area which you yourself can administer, that can work well. If you can use 5 GHz, it can work even better due to larger number of channels and worse propagation on that band resulting in less interference.

What I've seen used the most in such setups and with most success is the use of sort of light weight access points that are connected together over wired Ethernet. They are then connected to a central controller from which the network can be administered. In the older systems, you'd place a hexagonal honeycomb-like structure over the floor-plan and then set a frequency and power for each cell, so that adjacent cells have different frequencies. Today, smarter systems can do that on their own.

Anyway, what I find very strange is the term WAP-Repeater. It's pretty ambiguous (but I could be wrong). It can mean a wireless range extender that just picks up existing signal, amplifies it and re-broadcasts it, but those work on the garbage in, garbage out principle and are in general very bad. The other option would be a more active device which actually does some processing on the signal, but still those are pretty bad as well, since they usually rely on transporting actual consumer data over WiFi, which takes up bandwidth.

I personally don't like this question. There's much stress on the importance of fixing the issue (which is understandable) and the scale of the issue, but there's no information about the equipment used, there's no information about any type of band planning used, no diagrams of logical of physical connection between units, so there's very little that can be done at this point to help solve the issue other than some very general explenations.
