- Drones are equipped with high quality cameras to capture images of buildings
- Experts uses software to transform the 2D images into 3D models
- These models allow them to design radio links for urban environments
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.
