German 5G auction finalized - A closer look into the course of the auction

5Gauction

29.03.2019 – For all those who are interested in the 5G auction, CNI presents some statistical data derived from the auction results published by the BNetzA.

The statistics show first of all the progress of the bids and the sum of the frequency blocks associated to each bidding party. In addition to that the cost per frequency spectrum (in Euro/Hz) is calculated as well as the split of the frequency spectrum and its associated cost.

Based on the data, one can easily identify different phases of the auction (see below). After 3 months duration and almost 500 rounds the auction finally ended with a total of 6,550 Mio. Euro. The final outcome shows that the bidders associated with average bids of around 20 Euro/Hz more value to the 2 GHz-band compared to the 3,6 GHz-Band (with around 10 Euro/Hz average bid). This is due to the more favourable propagation characteristics of the lower frequency: the same coverage can be achieved with less base stations. 

The analysis has been originally prepared for the lectures "Mobile Radio Networks" and "Business Economics of Information & Communication Technologies". The discussion of the German 5G auction serves as a vivid and timely case study to demonstrate the close and complex interdependencies of technology and economics.

 

5G-Conference of VDE ITG committee with over 200 participants

ZdN-Netsys-2019

21.03.2019 – The timing could not have been better: just one hour before the national auction of 5G frequency bands was started on March 19, 2019, in Mainz, the participants of the 5G-technology-related conference „Future of Networking / Zukunft der Netze 2019 “ were welcomed by the chairs of the VDE-ITG commitee on communication networks and systems, Joachim Sachs, Ericsson, and Prof. Christian Wietfeld, TU Dortmund. The 16th conference of the series was jointly organized with the NetSys conference at TU Munich. The well attended conference featured invited talks primarily from industry representatives: from public and potential private 5G network operators (Dt. Telekom, Vodafone and Bosch), 5G international academia and manufacturers (IMDEA Madrid, Ericsson, Nokia) as well as further 5G stakeholders (such as automation manufacturer Siemens) and representatives from 5G related projects. Many participants also used the opportunity to attend sessions and workshops of the NetSys conference discussing primarily recent results from academic research. Within the VDE-ITG committee KT2, industry and academia representatives jointly organize workshops on „hot topics“ and regular conferences related to communication networks, such as the „Future of Networking“ conference series. Prof. Christian Wietfeld, head of the CNI at TU Dortmund, has been a co-chair of the KT 2 committee for over 10 years.

 

First Prize, IEEE ComSoc Student Competition Winners, 2018, Supervisor: Fang-Jing Wu

IEEE_Award

03.02.2019 – The outcome of our students’ project group has been awarded the First Prize by IEEE ComSoc Member and Global Activities Council for the IEEE ComSoc Student Competition 2018 in Abu Dhabi, United Arab Emirates. The project group entitled “Passenger Flows: Crowd Mobility Analytics with Edge Computing in Public Transport” is supervised by Junior Professor Dr. Fang-Jing Wu at Department of Electrical Engineering and Information Technology, Communication Networks Institute, TU Dortmund. The student team formed by Lucas Döring, Stephanie Althoff, Kai Bitterschulte, Keng Yip Chai, Damian Grabarczyk, Yunfeng Huang, and Lidong Mao, exploits Internet-of-Things techniques combining with machine learning algorithms to solve one of the important issues in public transport in smart cities. The goal of the developed system is to monitor passenger flows in an automated public transport system. To achieve this goal, lightweight embedded devices are integrated with multiple types of sensors for sensing wireless network activities and environmental conditions, and the onboard passenger estimation algorithms are designed for analyzing real-time data and further visualization. Therefore, the technical issues in wireless opportunistic communications, multi-modal sensing and data analytics, and visualization are addressed by the team. To conduct real-world experiments, the designed prototype was validated in the H-Bahn Dortmund that is an automated hanging train in the TU Dortmund’s campus.

The developed system was evaluated by an international committee with 45 experts nominated by the Competition Co-Chairs and by IEEE ComSoc Technical Committee, covering all areas. Two-round evaluation processes were performed by the committee from different aspects of social impact, technical content, originality, practical applicability and results, and quality of presentation. The developed system is characterized by giving insight into the uncertain wireless traffic and environmental conditions via an integration of sensing techniques, statistical learning algorithms, prototyping, and practical experiments in the real world, which makes the work particularly compelling and provide a physical gateway to a connected cyber world. Congratulations to the team at Communication Networks Institute, TU Dortmund.

 

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

5GmmWave

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 Vehicles (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.

 

TU Dortmund's CNI contributes to the establishment of the German Centre for Rescue Robotics in Dortmund

DRZ-CNI

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
