Has anyone used the Ubiquiti? I'm considering a mesh system for commissioning purposes.

Quite often I'm on construction sites where the client network isnt up, yet our cabling is complete so we use temporary switches for device configurations. I like the idea of having a reasonable sized wireless network up and running during commissioning.

How configurable are these things in terms of router/lan settings? Currently using an ubiquiti air router and it does what I need but its range is limited.
