C-V2X technology put to the test

¡Automundo also in GOOGLE NEWS!

La 5G Automotive Association (5GAA), the group BMW, Ford Motor Company y Groupe PSA in association with Qualcomm Technologies y Savari, performed a live demonstration of direct communication technology C-V2X, which operates on vehicles from multiple vehicle manufacturers and road infrastructure.

C-V2X technology put to the testC-V2X was operated using direct communications in real time on the spectrum for "Intelligent Transportation Systems (ITS)" and demonstrated its ability to work without cellular network coverage. This underlines its commercial readiness for industry rollout as early as 2020.

Demonstrations performed included electronic emergency brake light, intersectional collision warning, traffic turn collision hazard warning, slow vehicle and stationary vehicle warning, signal phase and road user and signal / time violation warning. vulnerable (pedestrian).

The vehicles involved included two e-scooters provided by the BMW Group and passenger vehicles provided by Ford, Groupe PSA and BMW Group, both of which were equipped with C-V2X direct communication technology using the chipset solution. Qualcomm 9150 C-V2X. Industry leader Savari provided application software and V2X software, along with route infrastructure.

C-V2X technology put to the testThe 5GAA involves more than 90 global members comprised of many leading vehicle manufacturers, first-tier providers, software developers, mobile phone operators, semiconductor companies, telecom and test equipment providers, traffic signal providers, and route operators.

Cellular modems will be key towards the implementation of C-V2X in vehicles to support telematics (combination of computing and communication technology for sending and receiving data), eCall, related infotainment and delivery of useful driving / traffic / parking information.

C-V2X technology put to the testSince the C-V2X direct communication functionality is built into the cellular modem, C-V2X solutions are expected to be more cost effective and economical compared to competing technologies, and benefit from accelerated connection rates. Validations of the C-V2X direct communication field are currently underway at Germany, France, Korea, China, Japan y United States.

Currently, C-V2X is governed as the only V2X technology based on the globally recognized Third Generation Partnership Project (3GPP) specifications, with continuous evolution designed to provide 5G compatibility.

C-V2X technology put to the testC-V2X also leverages and reuses higher layer protocols defined by the automotive industry, including the organization of the European Telecommunications Standards Institute (ETSI). It includes two complementary transmission modes: direct communication as shown in this demo for V2V and V2I use cases and V2N network communication, which leverages mobile operators for connectivity and offers cloud-based services, including automatic notification of faults (ACN, as provided by eCall), hazard warnings, weather conditions, optimal green light speed advice (GLOSA), parking spot location and remote tele-operation to support automatic driving, among others.
