CNI successfully contributes to 6G White Paper Expert Groups


30.04.2020 – While 5G is a major focus of the on-going research at CNI, we are also looking further ahead: CNI researchers have participated in recent months in two selected international expert groups which aimed to formulate 6G Research Visions. The white paper drafts are now publicly available online on arXiv. CNI representatives have specifically contributed to the White papers on "Machine Learning in Wireless Communications" and "Critical and Massive Machine-Type-Communication towards 6G". It was orignally planned that the 12 white paper working groups would meet in March 2020 at the 2nd 6G Summit in Finland. Due to the on-going travel and contact restrictions, the summit was organized as virtual event. The working groups continued their work successfully remotely from the respective home offices of the contributors.


100 Days Campus Network Planning Tool - A Statistical Analysis


28.04.2020 – Free offer of the Competence Center 5G.NRW is very well received.

At the beginning of the year the Competence Center 5G.NRW published the free service of the 5G Campus Network Planner (in German: 5G Campusnetzplaner). The aim of this service is to provide companies with a quick introduction to the local 5G radio license and to determine the frequency fee that is likely to be charged for the company-specific campus network in a few intuitive steps. Further details directly in the offer: https://5g.nrw/campusnetzplaner/. In this article, an analysis of the service's usage statistics is conducted.


We are ready – Introductory presentations to the online CNI courses of the summer semester are available as video streams


15.04.2020 – In preparation for the online teaching in the summer semester 2020 that will start next week, Prof. Wietfeld explains in two introductory videos the concept of the chair for the two key courses of the summer semester "Business Administration Basics of ICT" (Bachelor) and "Mobile Networks" (Master). Lectures and exercises are carried out as live streams with interaction possibilities for the students (chat, request to speak via video). The streams are recorded and subsequently made available in the student portal moodle, as well as the slide material as PDF. The components of the practical training, i.e. the business simulation as well as the development of a business plan for a self-chosen ICT innovation, will be possible from the home office with appropriate online collaboration tools. All students interested in the courses are asked to register via moodle to receive invitations to the respective online meetings. We are looking forward to an intensive and fruitful collaboration, despite the new boundary conditions.


On-going remote research and preparations for online teaching at CNI


22.03.2020 – In spite of the special "stay-at-home" situation imposed by the measures against the spreading of the Corona virus, the CNI team is committed to continue research and teaching by leveraging communication networks and corresponding online collaboration tools as much as possible. To all our students and partners: Stay healthy!

CNI congratulates Stefan Falten for receiving the Hans-Uhde-Award 2020


19.03.2020 – We are very happy to announce that Stefan Falten has been awarded with a Hans-Uhde-Prize for his outstanding master’s thesis “Implementation and experimental validation of a simulation model for the B.A.T.M.A.N. V routing protocol“. Within his thesis at the Communication Networks Institute, Mr. Falten has analyzed and optimized the performance of the novel bio-inspired routing protocol “Better Approach to Mobile Ad-hoc Networking V” (B.A.T.M.A.N. V) within highly dynamic ground-based and aerial vehicular networks. In order to assess the behavior of the routing protocol under challenging mobility conditions, he has transferred the existing Linux kernel module of B.A.T.M.A.N. V into an OMNeT++ simulation model which has been validated in real world experiments. The results of the thesis have made a significant contribution to a scientific publication, which has been presented at the international conference IEEE Vehicular Technology Conference (VTC-Spring) 2019.


CNI contribution to the 2nd 6G Wireless Summit


28.01.2020 – We are very pleased to announce that our paper "Towards cooperative data rate prediction for future mobile and vehicular 6G networks" has been accepted for being presented at the 2nd 6G Wireless Summit. In the paper, we bring together key results of two subprojects of the Collaborative Research Center "SFB 876" and take a look beyond the ongoing 5G standardization efforts that solely focus on bringing machine learning-enabled intelligence to the network side. Using the SDR-based passive control channel sniffer FALCON, we aim to mimic the behavior of a possible future 6G deployment where the network infrastructure actively provides information about the current spectral resource utilization to the mobile clients in order to improve client-based data rate prediction for anticipatory communications. In a real world proof-of-concept study in a vehicular scenario, we were able to improve reduce the average prediction error by up to 30% through the proposed cooperative approach.


Release of interactive planning tool for local 5G networks


16.01.2020 – After the much-noticed auction of 5G radio frequencies to mobile network operators in spring 2019, the Federal Network Agency launched the application procedure for additional local 5G campus networks in the 3,700-3,800 MHz frequency range in November 2019. As a consortium partner of the Competence Center 5G.NRW funded by the Ministry of Economics, Innovation, Digitization and Energy of the State of North Rhine-Westphalia, the TU Dortmund University developed the 5G Campus Network Planner, a tool with which all interested companies can determine in a few intuitive steps the expected frequency fee for the company-specific campus network.

NRW Minister of Economic Affairs and Digital Affairs Prof. Dr. Andreas Pinkwart states: "The Competence Center 5G.NRW started its work about half a year ago and supports companies and institutions in the early use of 5G. I am pleased that the work of the partners in the consortium is already bearing fruit. The 5G Campus Network Planner is a great free and user-friendly tool for quickly and easily estimating the costs of local 5G frequencies. I am confident that this nationwide unique offer will also meet with great interest beyond North Rhine-Westphalia. “


Master student project group C.A.R.E (Collaborative Aerial Rescue Robots in Emergency Response) successfully completed


20.12.2019 – As one of the final activities within the chair in 2019, the project group CARE (Collaborative Aerial Rescue Robots in Emergency Response) presented its final results to the members of CNI. The project group is part of the master course Electrical Engineering and Information Technology and challenges a group of students to solve a scientific task collaboratively. Within CARE, a group of 9 students realized a scaled system of ground and aerial robots which jointly executed emergency response several tasks, such as an exploration of an area affected by a natural desaster. But the highlight of the project group's presentation was surely, when two drones collaborated to synchronously transport an object within the given scenario to emulate a cleaning-up operation after a desaster. Despite the technical competencies, such as programming the control and communication of and between robots, the students also acquire practical knowledge regarding efficient project management and fruitful team work. A film about the final demonstration will soon be released on the video channel of our chair.


Dr.-Ing. Nils Dorsch receives dissertation award of the Rector of the TU Dortmund University


18.12.2019 – The CNI team congratulates Dr.-Ing. Nils Dorsch for receiving the award for the best dissertation in 2018/2019 within the faculty of electrical engineering and informatioon technology during the annual award ceremony of the university on December 16, 2019. Nils Dorsch's thesis is 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.-Ing. 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. The work of Nils Dorsch has attracted considerable attention: a first paper describing the overall system concept has been cited over 80 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) as well as another journal article on "Enabling Hard Service Guarantees in Software-Defined Smart Grid Infrastructures" in Computer Networks (Elsevier).
