Where do trains (and other moving things) get their interenet from?

I know cell phone providers sell data plans, but my understanding is that these have limited connection speeds - these days many trains offer "free wi-fi" for the passengers (I was even told of a shuttle bus that had wi-fi available). It can't just be standard cell phone data connection right? That would be hopelessly slow if more than a couple of passengers connected. Planes use satellite connections I think. What technology do land based - but moving - wi-fi hotspots use? Thanks
