The drone that can create a perfect 3D map of any town and could improve its wifi

The 8.6 billion mobile devices on the planet have meant that quite often, getting a decent signal can be tough. However, researchers say a new drone could be the key. It can create an incredibly detailed 3D map of a city, allowing researchers to model how radio waves move through it. Researcher have devised a new method that involves taking aerial photographs of an area with a drone, which can be used as models to design radio links. Drones are equipped with a high quality cameras that can capture multiple points of view.
