ConVeX Alliance Launches Europe's First | C-V2X Direct Communication Interoperability Live Demo

Recently, Audi, Ducati, Ericsson, SWARCO, Kaiserslautern University of Technology and Qualcomm Incorporated subsidiary Qualcomm CDMA Technologies GmbH jointly announced the successful implementation of the first bicycle in Europe between motorcycles, vehicles and roadside infrastructure. Networked direct communication interoperability live demonstration. The above parties established the 'Connected to the Future's Networked Cars' alliance last year and completed the first 3GPP Release 14-based C-V2X test, this time in Ingolstadt, Germany. Interoperability demonstration was performed. This demonstration uses Audi Q7 and Audi A4 cars and a Ducati Multistrada 1200 Enduro motorcycle with C-V2X technology equipped with Qualcomm 9150 C-V2X chipset solution. Common scenarios that may occur on the road between motorcycles and cars, and how to use C-V2X technology to improve road safety. These scenarios include intersection collision warning, that is, vehicles equipped with C-V2X technology exit from the intersection of adjacent roads. And avoid collisions with motorcyclists who have road rights, and warnings of cross-road corner collision risks, that is, vehicles avoiding left turn and Motorcycle collisions. These use cases are part of a wide range of advanced applications included in the ConVeX project. Previous applications demonstrated by the ConVeX Alliance include vehicle-to-infrastructure communication using SWARCO roadside infrastructure units and the use of Ericsson 4G/ 5G cellular test network, vehicle-to-network communication carried out in the German A9 digital highway test field.

The ConVeX Alliance is jointly funded by the various participants and the German Federal Ministry of Transport and Digital Infrastructure, and is part of the 'German Automation Network Driving Digital Test' project.

As part of the ConVeX Alliance's ongoing support for commercial deployment of C-V2X technology, the Alliance will continue to conduct a number of field trials this year to demonstrate the benefits of the unified C-V2X connectivity platform defined by the 3GPP Release 14 standard and to demonstrate C -V2X real-time direct communication has advantages in terms of range, reliability and delay. In addition, the trial aims to highlight several new use cases to help optimize traffic flow, improve safety and pave the way for autonomous driving.

During the test, the C-V2X direct communication for vehicle-to-vehicle, vehicle-to-infrastructure and vehicle-to-pedestrian scenarios runs on the spectrum of the 5.9GHz intelligent transportation system, eliminating the need for a SIM card and becoming a cellular user or network support. In addition, network-based communications can support car-to-network communications using wireless carriers' 4G and emerging 5G wireless networks, and operate on licensed spectrum owned by operators to support in-vehicle information processing, networked infotainment and increasingly diverse advanced Information security use case. The experimental V2N scenario runs on Ericsson's 4G and 5G test networks in Germany, which is based on the 2.6 GHz cellular band.

C-V2X technology continues to gain broad support from the global automotive and telecommunications ecosystem, and the 5G Auto Alliance, a joint venture between Audi, Ericsson and Qualcomm Incorporated, is a good example. The 5G Auto Alliance has more than 85 members, including Leading automakers, Tier 1 suppliers, software developers, mobile operators, semiconductor companies, test equipment vendors, telecom providers, traffic signal providers and road operators. C-V2X is a global solution for V2X communications. Designed to improve vehicle safety, improve automation and network driving and improve traffic efficiency, it is also the only V2X technology that follows global 3GPP standards and supports continuous evolution to achieve forward compatibility with 5G, making full use of the automotive industry – including Europe The upper level agreement has been defined by the Telecommunications Standards Institute.
