Live Streaming HD using a GoPro (or similar device)

Is it possible to wirelessly live stream HD video? I'm pretty sure it's not. If that's not possible, could you live stream HD with a Go Pro if it was connected to a laptop via HDMI? I need to live stream 6+ GoPros along a 300Ft tower using a 4G connection. In this just a stupid idea?

Check out livestream.com or Periscope. Other than that I dunno.

I think you could do it with a phone and a good connection - Periscope would work.

Too much extra stuff needed to make a Go Pro work effectively and you're not really losing anything quality-wise if your phone is new enough.
