This used to be via mobile hotspot, is it possible to do it any other way, but important without WLAN?
For the Pocket Edition, you only need to be logged in to your XBox Live accounts. Then you can play with each other. This is also possible with several kilometers distance
Depends on. Without it is not, but with the Fritz! Box e.g. Also, if the Internet does not work for some reason, so the internet time is over etc.
You do not need an xBox Live account for this. From 5 people already.
