CNI at High-profile Event on NRW's Digitalization Strategy

TU 5G mmWave Booth during the Presentation

02.11.2018 – CNI has been invited to present its latest 5G research results at the Digitalkonferenz.NRW. Following the invitation of Prime Minister of North Rhine-Westphalia Armin Laschet and Minister of Economics and Digital Affairs Prof. Dr. Andreas Pinkwart, over 500 guests from politics, business, science, culture and society came together to discuss the digital strategy for North Rhine-Westphalia with the state government on October 26, 2018.

At our booth we presented a 5G mmWave antenna tracking system, implementing a mmWave link at 28 GHz between a fixed base station equipped with a highly directional and electrically steerable pencil beam antenna and an Unmanned Aerial Vehicle (UAV). Beamforming and pencil beam antennas are expected to become a major component of 5G mmWave New Radio networks. While spatial separation and high gains are anticipated benefits, the suitability of those new antenna types in highly dynamic scenarios, such as the use on UAVs, requires appropriate real–time steering capabilities and needs to be proven in practice. In our testbed, a rail system is customized to generate precisely reproducible mobility trajectories of the UAV. In case the antennas are aligned within a given error margin, a stable air–to–ground highspeed connection (up to 3 Gbps) can be observed during the flight experiments.

Fire Truck with Aerial and Ground Rescue Robots

28.10.2018 – On October 1, 2018, a new project has started - funded by the German Ministry for Education and Research (BMBF) - which aims to establish a national competence center for rescue robotics. For the first time in Germany, first responders, researchers and industry will work closely together to realize autonomous rescue robots, which will become part of national as well as international robotic task forces for emergency rescue operations. Additionally, new test procedures will be developed, which will form the basis for standardization and certification of different robot systems acting outdoor on the ground, in the air, in water, as well as indoor. Based on its long-term track record in this research area, the Communication Networks Institute (CNI) will lead the work related to robust wireless communications of robotic systems, which allow for reliable operation even in challenging conditions of rescue operations

Dissertation on Software-Defined Networking for Energy Systems successfully completed

Dr. Dorsch with Traditional "Doktorhut"

08.10.2018 – The CNI team is happy to announce that Nils Dorsch has successfully defended his dissertation on October 2, 2018. The dissertation titled "Software-Defined Networking (SDN) for Real-Time Capable, Reliable and Cost-Efficient Smart Grid Communication Infrastructures" has proposed and investigated innovative concepts for communication networks suitable for the so-called Smart Grid. The work has been carried out within the interdisciplinary DFG-funded research group 1511 on "Control and protection systems for the future energy system". Dr. Dorsch has proposed a dedicated SDN interface which enables energy system operators to control the underlying communication system through a so-called north-bound interface. These extension of the Floodlight SDN controller originally developed at Stanford University have been also made available as open source. As a unique solution approach, Nils Dorsch has integrated the Network Calculus method into the real-time SDN controller to ensure that the maximum delay bounds required by the energy system are met. The work of Nils Dorsch has attracted considerable attention: a first paper describing the overall system concept has been cited over 50 times since its publication in 2014 at the IEEE SmartGridComm conference. An analysis of the economic impact of SDN-based networks has been recently published as journal article in NETNOMICS (Springer). Another journal article on "Enabling Hard Service Guarantees in Software-Defined Smart Grid Infrastructures" is accepted to appear in Computer Networks (Elsevier).

VDE ITG Thumbnail

14.07.2018 – 16 experts of the field of science and industry - among them, also head of the CNI Prof. Dr.-Ing. Christian Wietfeld - have published a discussion paper dealing with questions all about the open internet and the advancement of network neutrality in Germany. Head of the ITG Prof. Dr.-Ing Hans Schotten gives a classification (translated from German): "Recommendations, which technical boundary conditions have to be kept in mind concerning the advancement of network neutrality, are given. The intention of this is to ensure the essential goal of a transparent network access free from discrimination, on the one hand, but then also to be able to support services having high demands towards data transmission quality. Since the idea of static defined special services, for which exceptions are accepted, could impede innovations, intelligent dynamic mechanisms, that allow the different demands towards the 'open internet' to be realized simultaneously and as conflict-free as possible, are needed. The discussion paper gives an excellent contribution by presenting technical opportunities for action to the social discussion."

This project also inspires citizen science in which industrial and academic participants are making contributions to the open-source participatory ecosystem for PM2.5 monitoring.


5G Mobile Communications Lab at CPS.HUB/NRW Conference „Zukunft der Mobilität: Zwischen Datenschutz und Datenauswertung"

5G Mobile Communications Lab

28.05.2018 – Together with the Wirtschaftsförderung Dortmund, CPS.HUB/NRW has hosted the conference "Das nächste Level der Mobilität – Automatisierung, multimodale Services und die Rolle von Daten", at which internationally well-known scientists discuss the future of mobility. Among presentations by Prof. Dr. Fosca Gianotti of the KDD Lab in Pisa and Prof. Dr. Dimitrios Gunopulos of the University of Athens, there were also leading German scientists, who attended the conference, such as Prof. Dr. Katharina Morik. For the first time, as part of the associated exhibition, because of a recently purchased special vehicle of the Communication Networks Institute of TU Dortmund, the institute's powerful mmWave 5G New Radio test route could be brought into service in a field experiment. Due to the mobile 5G laboratory environment, with the aid of so-called Pencil Beams, it is possible to establish strongly directed communication links, which enable a data transmission rate from up to 2,8Gbit/s and therefore exceed current 4G systems in many respects. The usage of this 5G New Radio Hardware, that is not to be found at the market by now, enables the institute to actively work on the development of communication technologies of the future.


Sucessful Initiation of Unmanned Aerial Systems for the Support of See Rescue Operations

LARUS Early Demonstrator

26.04.2018 – In the case of the detection and rescue of shipwrecked people, every minute counts. Often, the voice-radio-based distress message is imprecise and does not contain all the necessary information for an efficient local rescue operation. This is exactly the point where the research project "LARUS - Lageunterstützung bei Seenoteinsätzen durch unbemannte Luftfahrtsysteme" begins. With the aid of a multisensor-platform in the shape of an autonomous flight system, the detection and rescue of the victims shall take place faster and more efficiently in the future. This was imposingly presented at an airfield in Rotenburg (Wümme) in front of an interested and impressed public. Here, the roundabout 30 guests had the chance to see the flight system in action and were presented with the project's innovations by understandable demonstrative superstructures by the consortium and detailed explanations.
