Here are the components that make up my professional home wifi system. I have two VLANs, one for home users and an isolated network for guests.
I also found this video extremely helpful in my set up.
Ubiquiti UniFi Switch 8 60W (US-8-60W)
Ubiquiti Unifi Security Gateway (USG)
Ubiquiti Unifi Cloud Key – Remote Control Device (UC-CK)
Ubiquiti Networks Unifi 802.11ac Dual-Radio PRO Access Point (UAP-AC-PRO-US)
They are Power Over Ethernet, so you need to have an Ethernet backbone. The Switch includes PoE ports to power the APs.
