I took on a job recently to rebuild much of the computer network of a large sports club in my area (a Bowling Club -- lawn, not tenpin) and it turned out to be a decent-sized job.
They have a reasonably large internal network with office PCs, networked point-of-sale terminals and an assortment of other devices, as well as wireless provided for staff and customers over two different SSIDs. Previously it consisted of four different unmanaged switches, an assortment of ISP-provided modem/router/wireless devices and an old Microtik box, so I proposed they should unify it all with UniFi
Some "before" pictures:
So from this I put in the following:
UniFI Pro-4 Gateway
Unifi 24 Switch Lite
Unifi 8-150w POE switch
Unifi AC HD access point
Unifi AC LR access point x2
UniFi Cloud Key
I decided to go with the Lite and the 8-150 because they weren't going to need more than 4-5 POE ports and because the server cabinet is in the office where staff worked I decided a 24-500w switch would be too loud. They had a substantial number of ethernet devices on the network to be patched in anyway, so the extra ports help. So it's all the network gear on the 24-lite and the three access points and the Cloud Key in the 8-150w.
After some setup and some issues with devices on a different network range (and some help here with that configuration), everything is now setup well. No more unmanaged switches and everything through a single network setup. They have a guest network setup with the UniFi portal and a staff network setup as the main internal network. They're happy with the result and I'm happy to have another regular customer
