Using existing cellular networks for drones

10.09.2019

It might soon become common for drones to transport goods and people, monitor disaster zones, and bring various forms of relief to areas that are difficult to access. Which communication infrastructure is best suited to facilitate this? Researchers at the University of Klagenfurt have explored potential challenges associated with the use of traditional cellular networks.

The communicative challenges facing drones are manifold: They need to communicate with a base station on the ground, but they must also be able to swap information with each other. This requires a pervasive wireless communication infrastructure, which traditional cellular networks are equipped to provide.

Aymen Fakhreddine, a senior researcher in the research group established by Christian Bettstetter at the Department of Networked and Embedded Systems, recently presented results from his research into how this utilisation might be realised at the ACM Workshop on Micro Aerial Vehicle Networks, Systems, and Applications in Seoul.

In order to address this question, the study focused on the use of drones in the LTE advanced network. The outcome: The transmission rates (20 Mbit/sec from the base station to the drone) are already adequate for numerous applications.

Nonetheless, it will be necessary to continuously improve the performance in order to broaden the set of functionalities. Researchers believe that the 5G network, currently still under construction or at the initial operating phase, carries great promise.

“At the moment, researchers have insufficient knowledge about the drone communication in real cellular networks”, Aymen Fakhreddine explains. Originally from Casablanca (Morocco), he studied in Madrid and Paris and has worked as a researcher in Singapore and Madrid.

The research currently being conducted at the University of Klagenfurt and the Lakeside Labs GmbH is realised in cooperation with MAGENTA (formerly: T-Mobile) and allows for experimental studies in real cellular networks. The mobile telephony operator supports the researchers by providing infrastructure and data from the mobile network.

In answer to the question whether a separate communication network could be built specifically for drones in the near future, Fakhreddine responds as follows:

“A brand new network represents significant costs. I believe that mobile operators will integrate drones into their existing infrastructure during the next five to ten years, before we can talk about the need/feasibility of a dedicated infrastructure.”

For now, the focus is on preparing the drones for integration in a 5G network, which also includes dealing with the issue of standardisation.

Im Focus: Physicists from Stuttgart prove the existence of a supersolid state of matte

A supersolid is a state of matter that can be described in simplified terms as being solid and liquid at the same time. In recent years, extensive efforts have been devoted to the detection of this exotic quantum matter. A research team led by Tilman Pfau and Tim Langen at the 5th Institute of Physics of the University of Stuttgart has succeeded in proving experimentally that the long-sought supersolid state of matter exists. The researchers report their results in Nature magazine.

In our everyday lives, we are familiar with matter existing in three different states: solid, liquid, or gas. However, if matter is cooled down to extremely...

Im Focus: World record for tandem perovskite-CIGS solar cell

A team headed by Prof. Steve Albrecht from the HZB will present a new world-record tandem solar cell at EU PVSEC, the world's largest international photovoltaic and solar energy conference and exhibition, in Marseille, France on September 11, 2019. This tandem solar cell combines the semiconducting materials perovskite and CIGS and achieves a certified efficiency of 23.26 per cent. One reason for this success lies in the cell’s intermediate layer of organic molecules: they self-organise to cover even rough semiconductor surfaces. Two patents have been filed for these layers.

Perovskite-based solar cells have experienced an incredibly rapid increase in efficiency over the last ten years. The combination of perovskites with classical...

Im Focus: Next generation video: WDR and Fraunhofer HHI present significantly improved video quality at IFA 2019

The demand for even higher resolution videos will continue to increase in the coming years. For this reason, the German public service broadcaster WDR and the Fraunhofer Heinrich Hertz Institute HHI will collaborate in the coming months to test the Video Coding possibilities offered by the next international standard VVC/H.266.

VVC/H.266 is the successor standard to HEVC/H.265. The latter is currently the most modern and efficient standard for Video Coding and is used, for example, in...

Im Focus: Nanodiamonds in the brain

The recording of images of the human brain and its therapy in neurodegenerative diseases is still a major challenge in current medical research. The so-called blood-brain barrier, a kind of filter system of the body between the blood system and the central nervous system, constrains the supply of drugs or contrast media that would allow therapy and image acquisition. Scientists at the Max Planck Institute for Polymer Research (MPI-P) have now produced tiny diamonds, so-called "nanodiamonds", which could serve as a platform for both the therapy and diagnosis of brain diseases.

The blood-brain barrier is a physiological boundary layer that works highly selectively and thus protects the brain: On the one hand, pathogens or toxins are...
