Workshop on scientific writing
The Mobile Systems Group of the University of Klagenfurt held a workshop on scientific writing. They discussed the typical parts of a paper along with specific challenges and practiced them in group work.

Using cellular networks for drones
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.
Research days: Communication in swarms
A workshop about communication in swarms took place in Klagenfurt in mid-July. Invited speakers and other experts discussed questions at the interface of robotics, distributed systems, and communication technology.
Panel: 5G opportunities and challenges
A panel on the next generation of mobile communication systems was held in Klagenfurt. Experts from two network operators, a chip vendor, and research institutions discussed the opportunities and challenges of 5G.
Unmanned aerial vehicle communications: Opportunities and challenges
Wireless communications is essential for many applications with commercial drones. Omid Semiari interviewed Christian Bettstetter about this exciting topic at the interface of communications and robotics for the latest IEEE ComSoc TCCN newsletter.
“Drones are here to stay. Get used to it.”
This statement was the title of a TIME article, which was included in the magazine’s special report on “The Drone Age”. We asked Christian Bettstetter to tell us what today’s drones can do and what drone (swarms) are not yet capable of. One thing is certain: Our airspace is going to be much busier in the future.
Robots that sync and swarm: A proof of concept in ROS 2
The swarmalator model for systems in which synchronization and swarming are coupled is implemented and studied for the first time in a technical system.
Guarded access balances out waiting times in transport systems
A transport system with passengers traveling between stations in periodically arriving cabins is considered. We propose and evaluate an access control algorithm that dynamically limits the number of passengers who are allowed to board the current cabin. Simulation of a ski lift using empirical passenger data suggests that such access control can balance out the average waiting times at different stations. The algorithm works well with estimated values of the arrival and de-boarding rates.
UWB connectivity in industrial environments
The connectivity of ultra-wideband (UWB) devices is studied in an aircraft assembly hangar and a production hall. These measurements are the first ones reported for off-the-shelf UWB devices in industrial settings and shed light on this technology’s potential to support emerging industrial applications.
One time for all: Synchronizing time in drone swarms
Wherever several clocks tick simultaneously, it is tricky to get them all to display precisely the same time. This can be a challenge for drone swarms that are airborne together. To tackle this problem, young scientist Agata Barciś is developing new technologies.
