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.

Exhibition at 2015 ITS World Congress

ITS_Bordeaux_logo_300dpi_350pxlQosmotec showcases its Car-2-X test system at the 2015 ITS World Congress in Bordeaux, France. Between October 5th-9th 2015 Qosmotec will demonstrate that it is not necessary to be a radio expert for running a channel emulation.

Qosmotec’s Car-2-X test system QPER C2X provides engineers with a powerful means to reduce testing on the road significantly, getting Car-2-X communication out of the transition zone. QPER-C2X emulates the radio transmission in car-to-car communication scenarios on a HiL test bench under real-life conditions. This powerful test system executes drive tests in the lab reproducibly. It is used for

  • ITS station benchmarking
  • integration of ITS stations into the car
  • finding the right antenna mounting position in the car
  • reproduction of complex traffic scenarios in the lab.

ITS World Congress attracts experts from the Intelligent Transport System field from all over the World – from the automotive industry to public systems operators and systems integrators to users.

Qosmotec’s exhibition at the 2015 ITS World Congress is located at booth F13. Click here to view the floor plan.

Exhibition at Driver Assistance Systems conference

Qosmotec presents its Car-to-X test system QPER-C2X at the 1st International ATZ Conference “Driver Assistance Systems – From Assistance to Automated Driving”.
At the conference top-class engineers and managers working in the interdisciplinary field of Car-to-X technology gather to evaluate technical concepts and their feasibility as well as their acceptance on the market. “We are proud to showcase our approach to test Car-2-X technology under real-life conditions in the lab at an event, where the roadmap for Car-2-Car communication for the next couple of years will be examined,” claims Mark Hakim, Managing Director Qosmotec.

The newly launched conference is held by ATZlive and specialist magazines ATZ and ATZelektronik. It looks at the technical challenges of driver assistance systems that are expected to be ready for series application until 2020. A special focus is set on testing methods requiring interdisciplinary and cross-sector development. “This is exactly where we fit in. We offer a testing method for repeatable and reproducible drive tests which makes approaches from mobile technology usable for Car-2-X communication,” states Hakim.

“Driver Assistance Systems – From Assistance to Automated Driving” takes place on April 28th and 29th at the Hilton Hotel, Frankfurt (Main), Germany.


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


Qosmotec’s project team for the integration of Azimuth’s channel emulator led by Iris-Marie Köster (left) with students from the University of Applied Science Aachen.

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.

Qosmotec at Mobile World Congress 2015


Between March 2nd and 5th Qosmotec will showcase its products at Mobile World Congress 2015, Fira Gran Via Exhibition Center, Barcelona, Spain.

At MWC 2015 we present our latest features and developments of our test systems:

  • QPER-C2X: Our test bench setup for Car-to-X communication. The extension of our signal strength emulator QPER for interoperability tests in Ad-Hoc network environments hands test engineers a powerful solution to examine Car-2-X technology under real-life conditions in the lab that allows them to accelerate the deployment of Car-to-Car communication. (See schematic on the left)
  • An extension of our non-blocking switches for QPER: RF-Switches, that select one from 40 RF inputs provide for a completely software controlled test lab and avoids any re-cabling of coaxial lines.
    RF Guard is available in different sizes to test larger UE such as tablets
  • Enhanced and optimised LTE testing procedures in our load and functional tester LTS.
  • A new shielding box for larger UEs such as tablets and prototype platforms with external USB and Ethernet interface.
  • On the roadmap and available soon: A voice recognition procedure that identifies  transmitted speech samples.

Meet our experts for a chat on automated network testing with integrated subscriber mobility emulation in Hall 6 Stand K11. Our famous stand-party will take place on Monday at 18:00. We would enjoy to welcome you there.
