Best way to connect to Enterprise WiFi?

I am looking at installing several Iotawatts in our local school to support student lead sustainability projects. The school can only provide Enterprise WiFi authentication into it’s network.

I’ve previously installed a WattWatcher device which was unable to support Enterprise authentication so we had to install a nearby 3G modem/router to get internet connection - expensive and precludes using locally hosted data storage (without re-downloading it from a remote server).

I don’t think Iotawatt supports Enterprise authentication either, but I wonder if there is a reasonably cheap & simple way to bridge the Iotawatt to an Enterprise connected AP perhaps?
