As part of the Mobile Radio Networks 2 (MRN2) course, the guest lecture from industry experts of VW Infotainment provided the master’s students with insights into the automaker’s experiences in the field of wireless vehicular communications and its standardization efforts for future cooperative autonomous driving applications.
Introduced by LTE release 12 specifications, cellular networks are able to integrate device-to-device (D2D) communications via the so-called Sidelink, which complements the typical Uplink and Downlink types of infrastructure-tied transmissions. This technology allows for full operation in out-of-coverage scenarios or relaying to devices exceeding the network’s reach, which is particularly interesting for the automotive industry in terms of vehicular communications. Thus, basic road safety features in the scope of Vehicle-to-Everything (V2X) services were specified by the late LTE releases using Cooperative Awareness Messages (CAM) and Decentralized Environmental Notification Messages (DENM) messages and later enhanced by the successor 5G. Hence, 5G features such D2D capabilities and continuously extends to advanced use cases, e.g. platooning as part of cooperative automated driving.
Within the scope of the Mobile Radio Networks 2 (MRN2) course, master’s students learn about advanced 4G/5G network features such as cellular V2X communications as well as WiFi amendments for car-to-car communications. VW Infotainment, located in the nearby city of Bochum and part of the Volkswagen Group, participates in relevant standardization bodies and industry associations. Therefore, CNI was happy to host experts Ernst Zielinski and Matthias Priebe who gave insights into the company and an expert talk on 5G standardization and V2X communications, nicely complementing and deepening the MRN2 course contents. The talk provided interesting insights into the automaker’s view and experiences in standardization efforts for mobile and vehicular wireless communication systems as well as into the role of industrial consortia such as 5GAA and C2C-CC.
All in all, the talk was a great experience for (future) telecommunications engineers and offered a refreshing view on the sector and future prospects. Once again, CNI thanks VW Infotainment and - in particular - Ernst Zielinski and Matthias Priebe for the interesting guest lecture and the fruitful Q&A session afterward.

Location & approach
The campus of TU Dortmund University is located close to interstate junction Dortmund West, where the Sauerlandlinie A 45 (Frankfurt-Dortmund) crosses the Ruhrschnellweg B 1 / A 40. The best interstate exit to take from A 45 is “Dortmund-Eichlinghofen” (closer to South Campus), and from B 1 / A 40 “Dortmund-Dorstfeld” (closer to North Campus). Signs for the university are located at both exits. Also, there is a new exit before you pass over the B 1-bridge leading into Dortmund.
To get from North Campus to South Campus by car, there is the connection via Vogelpothsweg/Baroper Straße. We recommend you leave your car on one of the parking lots at North Campus and use the H-Bahn (suspended monorail system), which conveniently connects the two campuses.
TU Dortmund University has its own train station (“Dortmund Universität”). From there, suburban trains (S-Bahn) leave for Dortmund main station (“Dortmund Hauptbahnhof”) and Düsseldorf main station via the “Düsseldorf Airport Train Station” (take S-Bahn number 1, which leaves every 20 or 30 minutes). The university is easily reached from Bochum, Essen, Mülheim an der Ruhr and Duisburg.
You can also take the bus or subway train from Dortmund city to the university: From Dortmund main station, you can take any train bound for the Station “Stadtgarten”, usually lines U41, U45, U 47 and U49. At “Stadtgarten” you switch trains and get on line U42 towards “Hombruch”. Look out for the Station “An der Palmweide”. From the bus stop just across the road, busses bound for TU Dortmund University leave every ten minutes (445, 447 and 462). Another option is to take the subway routes U41, U45, U47 and U49 from Dortmund main station to the stop “Dortmund Kampstraße”. From there, take U43 or U44 to the stop “Dortmund Wittener Straße”. Switch to bus line 447 and get off at “Dortmund Universität S”.
The AirportExpress is a fast and convenient means of transport from Dortmund Airport (DTM) to Dortmund Central Station, taking you there in little more than 20 minutes. From Dortmund Central Station, you can continue to the university campus by interurban railway (S-Bahn). A larger range of international flight connections is offered at Düsseldorf Airport (DUS), which is about 60 kilometres away and can be directly reached by S-Bahn from the university station.
The H-Bahn is one of the hallmarks of TU Dortmund University. There are two stations on North Campus. One (“Dortmund Universität S”) is directly located at the suburban train stop, which connects the university directly with the city of Dortmund and the rest of the Ruhr Area. Also from this station, there are connections to the “Technologiepark” and (via South Campus) Eichlinghofen. The other station is located at the dining hall at North Campus and offers a direct connection to South Campus every five minutes.
The facilities of TU Dortmund University are spread over two campuses, the larger Campus North and the smaller Campus South. Additionally, some areas of the university are located in the adjacent “Technologiepark”.
