Unifi AP NanoHD and Up/Downlink

we have a house with 3 floors. We want to make WLAN in all floors. The floors have no network connection. Can we take the Unifi AP NanoHD and connect it with up and downlink? The first NanoHD is connected to the Internet via cable. The second I would connect via uplink / downlink to the first. The third I would connect via uplink / downlink with the second. Have somebody already done that?

Yours sincerely

It will work, but when in mesh there is some speed loss and you have to do some testing to make sure they can talk to each other. https://blog.ui.com/2017/01/29/moving-beyond-conventional-wireless-network-unifi-mesh/
