Drone-captured 3D maps promise improved wireless networks
By using both the aerial photographs taken by the drone and photogrammetry software, they were able to create highly detailed 3D models of urban environments. These models can be used in designing radio links. Photogrammetry is a technique where 3D objects can be formed from two or more photographs.
‘The measurements and simulations we performed in urban environments show that highly accurate 3D models can be beneficial for network planning at millimeter-wave frequencies,’ says Semkin.
The researchers compared the simple modelling technique that is currently popular to their photogrammetry-based modelling technique.
‘With the technique used by us, the resulting 3D model of the environment is much more detailed, and the technique also makes it possible to carry out the design process in a more cost-efficient way. It is then easier for designers to decide which objects in the environment to be taken into account, and where the base stations should be placed to get the optimum coverage’, Semkin explains.
In the future, it will be possible to utilize the technique in designing 5G wireless connections, among other things.
