V2X (Vehicle to Everything) is the future of connected mobility, poised to power the connected automotive revolution. V2X, which consists of V2V, V2P, and V2I, enables instantaneous information transfer between cars and roadside infrastructures such as traffic signals, pedestrians, and commercial establishments.
There has been a powerful transition to the data-driven model in the automotive industry. For automotive OEMs, Car data is now more profitable than the car itself. Technologies such as ADAS, Self-driving, Connected Car, and Fleet Management have been powering the transformation in the automotive industry.
The digital transformation of the human mind has brought about a great change in the way we live, we travel, and consume experiences across verticals. V2X, as technology advances the digital transformation in connected mobility and enables higher levels of automated driving.
Additional data points from V2X systems can enhance the intelligence and decision-making capability of the car.
V2X is a milestone in the path towards a fully autonomous car and visualizes even further beyond.
V2X can help provide enhanced safety to drivers across the globe, improve traffic efficiency while reducing environmental impact. Based on the unique characteristics of V2X and information transfer, there are tremendous high impact use cases as listed below:
Lane change warning Upcoming traffic and Road Works
Collision Warning Driver and incident recording
Blind Spot Visualization Curve Zone warning
Work / School Zone warning Personalized advertising
Pedestrian Notifications Vulnerable Road User
Infotainment analytics In-vehicle safety
There are primarily 2 key communication technologies that power V2X: C-V2X and DSRC (Dedicated Short Range Communication) , Each varying on infrastructure. DSRC is built on a wireless communication system termed as “WAVE” while C-V2X is built on the traditional LTE modem. A DSRC radio will not be able to communicate with a C-V2X radio and vice-versa.
The standard for DSRC is defined in the Wi-Fi 802.11p while that for C-V2X is defined in the 3GPP Rel. 14/15.
C-V2X has 2 different communication modes: Network and Direct
However, there are a few similarities between both DSRC and C-V2X:
There have been varying interest across both technologies in different geographies. During the years 2015 – 2017, there had been widespread adoption of DSRC as it was the only V2X technology available.
Regulations and Technology Adoption
The Automotive industry and associations have been working with regulatory bodies across the globe to standardize V2X communication. Multiple governments consider V2X as a critical technology to reduce road fatalities and the way forward to minimize environmental impact. Governments are pushing the industry to shorten the deployment schedule for the technology.
Automakers are looking at C-V2X commercial launches in 2021 with the cellular LTE-based network access as 5G is not yet fully implemented.
Various automotive OEMs and industry players have now started integrating the V2X Stack in new automobiles.
V2X adoption is dependent on the Automotive OEMs, Mobile Network Operators, and industry associations. With V2X technology now commercially viable, with the use case and value proposition being understood and defined, it is a technology with a trajectory to enhance automated driving and revolutionize connected mobility.
