everything. you can look all up on youtube or read the manual...
there is everything described how to connect 2 ubiquiti locations together to access all devices (in vlans) ... vpn ... etc... there is a controller software , so its much easier to get it to work ... you dont have to deal with different brands for poe switch, bridges, router etc..
if you feel the need of accesspoints on locations, you just connect them to the poe switch, put them in another vlan,, really easy to deal with most network configurations
big community to ask questions...
