Hmmm. How did they measure that speed and what are they using for backhaul? Sticking a 4G mast in the middle of a field isn't too difficult and I'm sure you could get decent speeds to/from it. The question though is what does the mast talk to? Most people want to talk to the wider world, not just a mast ;)
"Sam Barker, senior analyst at Juniper Research, said its likely the mast will need to connect to a standard base station, 40-50 miles away"
