Using Qualcomm’s C-V2X chipset in Audi and Ford vehicles, demonstrations showed how C-V2X communications can alert nearby vehicles to potential hazards when the driver’s view may be obstructed, such as at traffic junctions and alerting other vehicles when turning or braking.
There was also a Vulnerable Road User (VRU) demonstration showcasing what can be possible with future vehicle-to-pedestrian (V2P) communications. Vehicle-to-Infrastructure (V2I) communication were also demonstrated, where direct communications work closely with traffic signal controllers to reduce carbon emissions and optimise traffic efficiency in busy areas and junctions.
The demonstration showcased the benefits of using C-V2X real-time direct communications on the 5.9 GHz ITS spectrum for vehicle-to-vehicle (V2V) collision avoidance and improved road safety, independent of the cellular operator network involvement, credentials or coverage.
The demonstrations produced initial field test results showing C-V2X direct communications had more than twice the range of 802.11p radio technology.
C-V2X is based on 3rd Generation Partnership Project (3GPP) specifications, which are recognised worldwide and designed to be compatible with 5G. It uses established security transport layers and application protocols defined by the automotive industry, including Society of Automotive Engineering (SAE) and the European Telecommunications Standards Institute (ETSI).
As well as vehicle manufacturers, the 5G Automotive Association (5GAA) took part. The organisation of automotive, technology and telecommunications companies was created in 2016 to develop, test and promote communications, standards and support commercialisation of connected mobility and road safety needs in autonomous driving and smart city transportation.
“After years of development supported by leading carmakers, technology providers and the automotive ecosystem at large, C-V2X is ready to improve road safety with deployment in production vehicles and road infrastructure as soon as 2020, leveraging a proven radio with decades-long developed automotive software protocols,” said Christoph Voigt, chairman of 5GAA.
