Hayat named “rising star” in networking and communications
The annual list Rising Stars in Computer Networking and Communications recognizes ten up-and-coming female researchers to honor their great career start. This year’s list features Samira Hayat, doctoral graduate from the University of Klagenfurt and now researcher at Lakeside Labs and founder. She is the first Austrian-based scientist to receive this award.
Drones in cellular networks
A new project investigates the integration of unmanned aerial vehicles in 5G networks and proposes a hybrid connectivity solution with Wi-Fi. The work is led by Aymen Fakhreddine and advised by Christian Bettstetter. Funding comes from the Austrian Science Fund (FWF). Written by Christian Bettstetter and Aymen Fakhreddine Wireless connectivity is a fundamental component in drone systems with high demands for reliability, security, and performance. Some drone applications need to transmit huge amounts of data or require ultra-low latencies. The wireless technology used in most commercial drones is Wi-Fi, but it only partially meets the high requirements. Therefore, integrating drones into cellular networks is an exciting option, either as a replacement or supplement to Wi-Fi. A new three-year research project at the University of Klagenfurt addresses this issue. Funding was secured from the Austrian Science Fund (FWF) in the amount of about 288,000 € from the ESPRIT postdoctoral program. The work is embedded into many ongoing activities on multi-drone systems in Klagenfurt (uav.aau.at). “The integration of drones into cellular networks has not yet reached the …
Wireless connectivity in airplanes
The aviation industry is interested in wireless solutions for in-plane connectivity to improve safety and reduce airplane cost and weight. Ultra-wideband (UWB) seems to be a suitable technology for this purpose due to low power consumption, high data rate, and coexistence with other systems.
Offloading computation to 5G networks: Helping drones to improve their autonomous navigation
Commercial drones usually come equipped with modest on-board computing power. Consequently, their speed and agility are somewhat limited when they use their cameras like eyes to navigate in space. Samira Hayat, a researcher at the Department of Information Technology, recently joined forces with colleagues from other departments and Deutsche Telekom to investigate the effects of offloading computation to the edge of the network (edge computing).
Multi-drone systems: Embedded wireless sensor networks in the air
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.
