Netgear Orbi WiFi 6 RBK852 vertical coverage through linters

[jips11in]

How much vertical coverage through concrete rebar slabs I can get using Netgear Orbi WiFi 6 RBK852 ? Can it cross two concrete rebar slabs i.e 2 floors say from 1st floor to 3rd floor (vertical distance is 25 feets) ?

No experience with that however i kinda doubt much signal will travel thru that kind of concrete and steel. 

How thick are these slabs?

Including floor titles the slab thickness would be 8-9 inches. Finally purchased it and router and satellite can be connected on wifi backhaul with just one floor vertical distance. It dosen't work with two floor distance. So I would need one satellite for 3rd floor.

Probably. I would make it wired if possible:
