Connecting multiple mobile users

I'm looking to make a multiplayer game. Specs are:
>Android OS
>Mobile devices
>Not picky about connection type (bluetooth vs wifi network vs whatever other options are available).

I'm very new to networking though, and am not sure what built in systems Unity has to support this. Any experts here able to point me in the right direction as for the easiest way to do this? Does not need to be incredibly robust as this is a personal project, not something I'm looking to publish at large.

Thanks a ton!

 

I'd run through some UNet tutorials on PC first to get the hang of it (since UNet is built in and does ok for the most part), then try moving them over to mobile while your mobile device is connected to your home wifi.
