On average, there are 6 million car accidents in the U.S. every year, with Massachusetts holding the top spot for the highest percentage of drivers with a prior at-fault accident. That’s roughly 16,438 people per day who never return home.
However, the rollout of 5G technology paved the way for Vehicle-to-Everything (V2X) connectivity. And with that came a ray of hope for the next estimated 14,794 people to return home safely, and the next after them, and so on.
“Of the 6 million vehicle accidents in the U.S. alone every year, an estimated 90 percent are preventable, meaning that most accidents were caused by human error according to a report on distracted driving published by the National Highway Traffic and Safety Administration. V2X technology is expected to reduce human error and save many of those lives. V2X aims toward solving this problem because the computer doesn’t get tired.”
– Robert Bielby, V2X expert & senior director of automotive system architecture in Micron’s Embedded Business Unit
What is V2X Communication?
V2X or Vehicle-to-Everything is a communication system that enables the transfer of information from a vehicle to another and the traffic system to further improve road safety.
The technology came into being with the idea to enhance road safety, energy savings, and traffic efficiency on the roads. The main elements of V2X include vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), vehicle-to-grid (V2G), vehicle-to-cloud (V2C), and vehicle-to-device (V2D) communication systems.

Within the V2X communication system, the information travels through high-bandwidth, high-reliability links from the vehicle sensors and other sources. This allows the vehicles to commute with other cars, infrastructure such as parking spaces and traffic lights, and smartphone-tossing pedestrians. This technology helps to improve traffic efficiency by warning drivers of upcoming traffic, suggests alternative routes to avoid traffic, and also helps to identify available parking spaces.
Market Growth and Size
According to MarketsandMarkets, the V2X market is expected to grow more than $12 billion by 2028 compared to $690 million in 2020. However, the V2X market witnessed a slow growth in 2020 due to low vehicle sales amidst COVID-19. But overall, the market is growing substantially due to the high demand for automobile safety features and better traffic management.

V2X by Connectivity
V2X communication can be achievable in two ways:
- WLAN
- Cellular
V2X communication uses WLAN and works directly between vehicles to vehicles or vehicles to infrastructure.
But, in 2016, 3GPP made cellular V2X standard in Release 14 to use cellular technologies such as LTE or 5G to provide V2X communication.
While some countries are adopting CV2X, others are choosing WLAN Based V2X. Both CV2X and WLAN-V2X have their own cons and pros and depending on the requirement, companies are adopting one. But CV2X seems to have more advantages over WLAN-V2X.
Thus C-V2X became more famous over the period of time as 5G boosts the communication and removes the hurdle that 4G was not able to.
“Recent testing has shown the superior performance of C-V2X relevant to non-cellular ITS technology. Wi-Fi […] has no relationship to existing cellular infrastructure, nor will it be compatible with 5G, which provides the best of both worlds: direct short-range communication in unlicensed bands and long-range communication with 4G and 5G. C-V2X also facilitates ad-hoc vehicle communication in situations with no cellular coverage.” – Joakim Reiter, Group External Affairs Director, Vodafone.
Companies like Qualcomm have been researching and promoting C-V2X as it started to provide solutions to autonomous vehicle companies.
Not just companies but major countries like the US, China, and Japan are also favoring C-V2X. Besides that, some European countries also prefer C-V2X. In 2019, 21 European countries voted against a motion to close down 4G/5G-based V2X communication.
Further 5GAA consortium is also promoting C-V2X among major companies to adopt the technology. The consortium already has major companies as its members such as automotive, telecom, and technology players.

Top Markets
China is leading the V2X as the country is the top R&D center and potential market for the technology, particularly C-V2X. More than 20 trials and pilot projects are taking place across 100km of roads in 10 provinces. In Wuxi, in eastern Jiangsu province, where C-V2X already covers 170 square km of urban land, China Mobile and supplier Huawei planned to nearly double that coverage to 400 intersections by the end of 2019.
“5GAA is instrumental in supporting the implementation of C-V2X technology in different parts of the world including China. The momentum in China reflects the fact that C-V2X is the verified, mature, and preferred future-proof technology for connected vehicles.”
– Luke Ibbetson, 5GAA Board Member and Vodafone Group’s Head of R&D.
Further patent data also tells us that most of the V2X research has happened in China following by the US. Being a lucrative market, more than 15 automakers announced their plan to roll out cars supporting C-V2X for the Chinese market from the 2nd half of 2020, according to 5GAA.
The patent data also tells that China seems to be the potential market for C-V2X technology as companies tend to save their C-V2X innovation in China.
But as for research and development, the US is leading for C-V2X most likely because of Qualcomm which is the top company researching C-V2X.
Future Outlook
Based on Market prediction and technical development, it is safe to say that the technology will grow in the coming year and boost safety for self-driving vehicles.
And with 5G and AI, companies can solve the technical challenges of V2X, especially C-V2X. Also, it could make C-V2X a more mainstream option than WLAN-Based V2X. 5G and AI open a whole new door for many technologies to improve and with C-V2X, it can improve it to an unexpected length that 4G failed to do so.
“C-V2X technology is set to revolutionize the mobility ecosystem and the way vehicles and drivers interact with the world, including vulnerable road users such as pedestrians and cyclists. It is an essential stepping stone for the ongoing digitization of transportation by providing real-time, highly reliable, and actionable information flows to enable road safety, traffic efficiency, and environmental progress.”, Maxime Flament, CTO, 5GAA.
“The auto and telecom industry – collaborating under 5GAA – supports the idea that 5G will further enable mission-critical enhanced V2X communications and be the ultimate platform to enable impactful C-ITS services.”
5GAA is trying to promote CV2X and has been successful in attracting many global players to adopt it.
