In order to provide 4G coverage to UK's rural areas, Mobile network provider EE has unveiled plans to use drones and balloons. The helium balloons hover at a height of about 150 feet and can cover an area 4 kilometres wide, while the drones can provide coverage over an area 2 kilometres wide for a few hours.  the network could be used in the wake of natural disasters as well as during events like soccer matches, says the company.
