My family is buying a townhouse in NYC and I’m responsible for the Wi-Fi setup. It’s a gut-renovated 1899 building but has Cat6 drops per floor. I’m just not happy we’re losing fiber.
In our current apartment, there are two wAP AXs: one on each opposing side. The new place will have one wAP AX per floor as it’s a four-floor building.
The question is what’s the range for a wAP AX? I’m in the US but if you know the square meters it’s fine.
Best thing is to test it yourself. There are a lot of factors that will influence wireless performance like type of wall, interference from other APs in the area, position of the AP.
Also there is the question of speed. What speeds are you expecting on your devices ?
And I would add also where the cat6 sockets are located, if on the ceiling of a central room the wAP is not so suitable as it Is not omnidirectional and a cAP (or another manufacturers ceiling AP) would be more suitable.
That Is if the floor plan Is roughly a square, if It Is long and narrow it’s another thing.
I don’t think that the one or the other manufacturer - provided that regulations are respected - does miracles, so devices with the same intended use and with similar power will have roughly the same coverage.
Some other manufacturers do provide planning software that should be usable to give a rough theoretical estimation.
