Participants at the RelCovAir launch at Erlangen, Germany.

Qosmotec participates in an international Consortium to develop a test and simulation environment for Industry 4.0 applications. The project called “Reliable Industrial Communication over the Air” (ReICovAir) started last week with a kickoff in Erlangen, Germany, and aims to develop methods and tools for testing wireless communication systems for industrial production processes which demand a very high reliability.

RelCovAir has been set up within the EUREKA-Initiative CELTIC-Plus. Currently, companies and research institutes from Germany and Finland are participating in this joint project. Partners from Spain and France are expected to join during this year. The German consortium, that is funded by the German ministry for education and research (BMBF), consists of several partners, with whom Qosmotec has already been working for a long time: The Fraunhofer Institutes IIS and HHI, the Institute for automation and communication (IFAK), CETECOM GmbH as well as GHMT AG.

“Fraunhofer IIS, who have taken over the lead for the initiation of this project, have managed to assemble a very strong consortium in Germany with plenty of expertise in radio channel modeling and test and measurement on the air interface”, says Qosmotec’s General Manager Mark Hakim. “Similar to the Car2X project, where our joint activities with a chair from the university in Aachen and CETECOM have been funded by the ministry for economy, we expect a good outcome of this project and the development of test systems for a new application area.” The project runs until autumn 2018.

Qosmotecs Feldstärkeemulator QPER-C2X erstmals bei Automobilhersteller im Einsatz

c2x-szene1

Funkbedingungen einer Testfahrt simuliert mit QPER-C2X

Noch in diesem Jahrzehnt soll der Nachrichtenaustauch von Fahrzeugen untereinander (Connected Cars) als Fahrerassistenzsystem auf Europas Straßen zum Einsatz kommen und damit für mehr Fahrkomfort zu sorgen, wo Kamera- und Sensorsysteme an ihre Grenzen stoßen. Dies hat das Car2Car Consortium vor wenigen Wochen angekündigt. Um dieses Ziel zu erreichen, braucht es nun auch effiziente Testverfahren, die den Bedarf von aufwändigen Testfahrten senken und vor allem die Reproduzierbarkeit der Ergebnisse sicherstellen. Mit dem Feldstärkeemulator QPER-C2X des Aachener Unternehmens Qosmotec wird der Funkverkehr zwischen Autos im Testlabor realitätsgetreu nachgebildet. In der Volkswagen Konzernforschung kommt dieses System nun erstmals auch direkt bei einem Automobilhersteller zum Einsatz.

„Von den Funkübertragungsbedingungen hängt es in entscheidendem Maße ab, ob ein Verkehrsteilnehmer eine Nachricht eines anderen Autos überhaupt bekommt. Nur sind diese Bedingungen an derselben Stelle nie identisch“, erklärt Qosmotecs Geschäftsführer Mark Hakim, warum sich auf der Straße Fehler so schlecht reproduzieren lassen. QPER-C2X erweitert Hardware-in-the-Loop Prüfstände, auf denen alle Funktionen im Fahrzeug unter die Lupe genommen werden, um die Kontrolle der Funkschnittstelle zu anderen Fahrzeugen und Infrastrukturkomponenten entlang der Straße. Dies ermöglicht es den Entwicklern, die Funkbedingungen während virtuellen Testfahrten am Prüfstand zu erproben. So haben die Ingenieure Gelegenheit, bereits in der Prototypenphase Interoperabilität, Signalübermittlung und Störfestigkeit unter wiederkehrenden Voraussetzungen zu prüfen. Darüber hinaus können sie die Eigenschaften und Einbaupositionen der Antennensysteme in verschiedenen Fahrzeugmodellen testen.

Für den Einsatz bei Volkswagen hat Qosmotec nun zwei spezielle Erweiterungen hinzugefügt: Eine Anbindung zu der Verkehrssimulationssoftware SUMo (Simulation of Urban Mobility) ermöglicht es, dies unter realitätsgetreuen Verkehrsbedingungen zu tun. Auch eine hohe Auslastung der Funkkanäle, wie sie beispielsweise in Staus oder bei Großveranstaltungen auftreten können, lässt sich im Labor nachstellen.

All diese Tests sind mit jeder in Frage kommenden Funktechnologie möglich – auf Basis von LTE, dem eigens für die Fahrzeugkommunikation entwickelten ITS-G5 Standard, oder sogar den noch in der Entwicklung stehenden Technologien der fünften Generation.

Instead of Christmas cards: Qosmotec funds dictionary for refugees

This year we want to use the amount that has been spent on Christmas cards, giveaways and little gifts to support a local initiative for integration of refugees. The library in Herzogenrath near Aachen plans to hand out free visual dictionaries to refugees for self-education in German language. These picture books show more than 6.000 terms in figures with the German notation and pronunciation and even explain basics of German grammar.
Gertrud Elsenbruch, who teaches children and families on voluntary basis, explains the idea behind this: “Especially for those, who have just arrived, the offers to learn German are very restricted. The voluntary lessons are more a psychological help than a target-oriented education. And a lot of them do not speak arabic, as there are many refugees from other countries.”
Together with other voluntary teachers, Gertrud Elsenbruch wants to distribute the books to refugee families in their hometown and participants of their classes.

ITS-G5 delay is Car2Car testing tools’ big chance

 

Qosmotec’s Sales Partner Ferdinand Schuber demonstrates the need for reliable Car2Car Communication testing.

Qosmotec’s Sales Partner Ferdinand Schuber demonstrates the validation of propagation models in Car2Car Communication testing.

A message from Niels Peter Skov Andersen, General Manager of the Car2Car Communication Consortium, was reason for controverse discussions at the 2015 Car2Car Forum in Mainz: He announced that the Consortium members have agreed to delay the deployment of ITS-G5 communication in Europe to 2019.

What sounds as a significant backslash for the technology is a big chance for test and simulation tools like Qosmotec’s QPER-C2X. “Those who have invested years into this communication technology must take care now that their developments do not become obsolete by modern communication technologies like LTE direct. They depend more than ever on efficient test systems that allow to test communication between cars in the lab in order not to lose even more time now”, says Qosmotec’s General Manager Mark Hakim, who is attending the congress together with our Sales Partner Ferdinand Schuber from FSTC in Vienna.

The focus of Qosmotec’s booth presentation at the congress is to show a method for validating the channel models that are applied in QPER for signal propagation by comparison with measurements on the road. For this purpose, Qosmotec’s certification partner CETECOM has developed a 8-sector transmitter that can be used to verify the signal propagation on a selected area and compare them with the results of the propagation model.

We demonstrate in the congress hall, how these measurements are done and that signal reflections on walls become easily visible with this method. “We have been often asked about the accuracy of our models and now we can show that our simulations and predictions are reliable even for dedicated areas,” says Ferdinand Schuber.

 

 

ITS World Congress: a positive for Qosmotec

20151007_183559Qosmotec is currently presenting its radio propagation and signal strength emulation environment QPER-C2X at the ITS World Congress in Bordeaux. Qosmotec’s Sales Manager Ferdinand Schuber gives a positive review of the congress’ first half: “It becomes obvious that many stakeholders do not only want to rely on ITS-G5 as the only communication standard, but also go for communication via 4G and even 5G in the future. Our solution holds the advantage of being versatile enough to cope with any radio transmission technology”.

Nevertheless, C2X communication is a big subject on the congress. Citroen / Peugeot have setup a real-life demo outside the exhibition hall to showcase their implementation inside the car. Also other car manufacturers like Toyota, Renault and Honda have put a clear focus on this technology in their presentations on the congress. The exhibition is still ongoing until Friday, Oct 9th. The Qosmotec booth is in Area F, booth number 13.

Qosmotec and Azimuth collaborate on real-world Car-2-Car testing

Projektteam_Azimuth_Integration

Qosmotec and Azimuth Systems, Inc., a leading provider of automated, realworld mobile performance test solutions, announced a joint collaboration for developing a Car-to-Car (C2C) test solution. By combining Qosmotec’s signal strength emulator QPER with Azimuth’s ACE MX channel emulator, the solution simulates all traffic, mobility and channel aspects of a C2C environment. This solution enables realistic, and comprehensive C2C interoperability testing in the lab.

Testing Car-to-Car communication in the lab requires the emulation of a significant number of radio links (each of which maps to a link between two cars), some links requiring primarily just attenuation and others requiring a complete radio channel. Qosmotec’s field strength emulator system provides the attenuation links for these tests; the field strength emulator offers a large number of configurable links that can be configured to reflect the different path loss between the cars. Azimuth’s ACE MX channel emulator complements this by emulating the complete radio channel (path loss, Doppler, propagation delay, AWGN etc.) for links that require a complete radio channel. The QPER-C2X software controls this integrated solution and provides a graphical interface to create and configure the physical environment and the traffic model.

The ACE MX is a part of Azimuth’s industry leading portfolio of channel and environment emulators purpose-built for testing real-world device-network interactions and their impact on end-user performance. The underlying platform is architected to support existing and forward-looking technologies and enable rapid development and automation of applications and solutions such as C2C communications.

Qosmotec’s QPER-C2X is a signal strength emulator enabling to interconnect up to 15 radio modules and thus simulating a high number of individual radio as they are established in Ad-Hoc networks. It emulates all kind of signal strength effects like path loss, shadowing, fast fading or antenna shaping on each individual path. These effects are automatically generated, when the tester runs a traffic model that can simply be created on a graphical user interface. Besides to that, QPER-C2X offers an open interface to integrate with traffic modeling tools that are well established in the automotive industry like the open source software SUMO.

Pete Paglia, President of Azimuth Systems, said, “Azimuth is excited by our leadership in channel emulation and its application in emerging areas such as C2C. Azimuth has a strong track record of developing innovative solutions for emerging applications and we see C2C as an area where we can contribute to this evolving industry by leveraging our leadership in channel and environment emulation along with our solutions expertise. We look forward to building on the strong collaboration that already exists between Qosmotec and Azimuth. Together we can provide end-to-end real world test solutions that help our mutual customers better emulate the environment and test C2C more comprehensively.”

Mark Hakim, Managing Director at Qosmotec, said: “Now, where Car-2-Car technology is on the step between research activities and rollout on the streets, systems for interoperability testing become indispensible. Nobody wants to risk mounting a technology in cars that has not been examined under absolutely real-life conditions. Our joint solution with Azimuth enables us to offer a best fitting solution for emulating air interface conditions on a test bench. This will accelerate the deployment of Car-2-Car communication.”

On Qosmotec side, a team of five Bachelor students from the University of Applied Science has been working on the development of traffic scenarios, that are dynamically executed on the Azimuth ACE MX channel emulator. Iris-Marie Köster, head of the team, was excited about the achieved results: “It feels fantastic to put scientific knowledge into pratice this way.”  From next week on, Iris will operate the developed prototype on the ITS plugtest in Helmond.
