Qualcomm Technologies is working with Datang Telecom Group, also known as China Academy of Telecommunications Technology (CATT), and additional players of China’s automotive ecosystem to host these live demonstrations showcasing multi-vendor chipset interoperability and intelligent transportation system (ITS) stack compatibility between automakers and roadside infrastructure. The demonstrations are expected to utilize the Qualcomm® 9150 C-V2X chipset and Datang’s LTE-V2X module, the DMD31, both of which were the first chipset-level LTE-V2X systems announced as interoperable in August.

Also known as C-V2X across the globe, LTE-V2X is a global solution for V2X communications, which is designed to support improved automotive safety, traffic efficiency, and automated driving using high performance and reliable real-time direct communication between vehicles, as well as with roadside infrastructure, and is on an evolution path supporting additional functionality as part of 5G New Radio (5G NR).

The demonstrations are expected to utilize passenger cars provided by the aforementioned automakers, all of which will be equipped with LTE-V2X technology using the Qualcomm 9150 C-V2X chipset to demonstrate the benefits of vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications. V2V and V2I communication supports collision avoidance and traffic efficiency applications built on top of the China-SAE ITS stacks provided by Genvict, Nebula Link and Savari Inc. Roadside units (RSUs) featuring the Qualcomm 9150 C-V2X chipset are expected to be stationed along the roadways and on traffic signals, providing comprehensive V2X services such as local dynamic map, signal phase and timing and roadside sensor sharing.  


Collectively, the seven V2V and V2I use cases that will be demonstrated include: Optimal Speed Advisory, Lane Change Alert / Blind Spot Alert, Emergency Brake Warning, Forward Collision Warning, Emergency Vehicle Warning, Intersection Collision Warning, and Slippery Road Alert.

LTE-V2X PC5-based direct communication operates in the 5.9 GHz spectrum that the China government recently designated for LTE-V2X ITS applications and works independently of cellular operator network involvement. Through these demonstrations, China is well-positioned to demonstrate leadership in LTE-V2X with commercial readiness for RSUs, onboard units and vehicle integration in 2019.
