Industry Standard C-V2XFrom 4G to 5GNews and Resources

More than 500 million connected cars will be on the road by 2025 (Ericsson, 2019) and connected vehicle services will be worth US$ 81 billion by 2030 (Strategy& | PWC, 2019), making the connected vehicle market one of the highest growth areas in the IoT and providing an immense revenue opportunity for mobile operators, automotive manufacturers, and companies in the wider ecosystem.

More importantly, the connected vehicle market is also the area with the biggest impact on the safety and well-being of citizens. By 2025, connected cars could save 11,000 lives and lead to 260,000 fewer accidents every year, while avoiding 400,000 tonnes of CO2 emissions and saving 280 million hours of driving (Bosch, 2017).


Industry Standard C-V2X

C-V2X (Cellular Vehicle-to-Everything) is the technology that will allow the connected vehicle market to scale to its full potential. C-V2X is an enhanced 3GPP LTE standard that describes a set of technologies enabling communication messages between vehicles, infrastructure and people. Its uses and benefits include enhanced safety, more efficient driving, reduced traffic congestion and pollution, and value-added services for end customers.


V2V (Vehicle-to-Vehicle) technology allows vehicles to talk to each other. Use cases include, for example, sending and receiving collision warnings at traffic turns and intersections to improve traffic safety, and warnings about hard emergency braking or stationary vehicles to avoid rear end crashes.


V2I (Vehicle-to-Infrastructure) technology allows vehicles to talk to road infrastructure, such as traffic lights, speed signs and toll stations. For example, where drivers can monitor the status and change time of traffic lights, they can anticipate when to slow and accelerate. This not only improves traffic flow and prevents accidents, but also saves fuel and reduces air pollution.


V2P (Vehicle-to-Pedestrian) technology helps to protect vulnerable road users by issuing collision warnings to the driver and the pedestrian or cyclist, making streets safer not just for drivers, but all traffic participants. This safety-critical service can be delivered in two ways: by leveraging the cellular network, whereby a pedestrian or cyclist becomes visible to a vehicle via an application on their smartphone, or by direct communication between vehicles and vulnerable road users, whereby C-V2X technology is embedded directly into the smartphone.


V2N (Vehicle-to-Network) technology allows vehicles to talk to the mobile network, enabling highly reliable, longer-range communications between vehicles (V2N2V), infrastructure (V2N2I) and vulnerable road users (V2N2P) by using existing cellular infrastructure. Enabling vehicles to communicate with their surroundings and other smart transport solutions beyond line of sight and around blind corners further increases traffic efficiency and safety on the road.

C-V2X technology enables highly reliable, real-time communication at high speeds and in high-density traffic. Indeed, it has been tested and proven to consistently provide superior levels of security, range, latency and reliability that vastly exceed the capabilities of alternative solution DSRC/802.11p.

The technology also comes with the support of a strong global ecosystem, with over 130 leading mobile operators, vendors, automotive manufacturers, suppliers, and companies from the wider industry backing C-V2X.

Since C-V2X is a globally supported and much more recent and efficient technology compared to DSCR/802.11p, governments must put in place appropriate regulatory frameworks to make our roads safer and smarter. Regulators can accelerate the development and scaling of the market by facilitating trials, encouraging investments, implementing needed roadside infrastructure, providing the necessary frequencies and advocating for a technology-neutral landscape.


From 4G to 5G – Autonomy and Mobility at Scale

C-V2X technology is commercially available globally, leveraging the secure and established 4G LTE network infrastructure to provide the benefits of a connected vehicle market already today. With 5G, C-V2X and the connected vehicle market will scale to its full potential, enabling fully autonomous and connected driving, and delivering societal benefits, value-added services and business opportunities at large.

Indeed, C-V2X is already evolving from 4G LTE networks (LTE-V2X) to the next generation of mobile networks (5G NR-V2X), meaning that new 3GPP releases continuously provide fundamental enhancements to the technology, and that C-V2X is the only connected vehicles technology with a sustainable roadmap to 5G that upholds backward compatibility.

5G is also crucial for the transformation of the mobility ecosystem. A fully Cooperative Intelligent Transport System (C-ITS) leads to further reduced congestion and pollution, safer and efficient driving, new business opportunities for mobile operators and automotive manufacturers, innovative value-added services for customers, and a more efficient travelling experience for citizens and commuters across all means of transport.


What the GSMA is doing

The GSMA is working with mobile operators, automotive OEMs and suppliers, industry associations and regulatory bodies to accelerate the growth of the connected vehicle market by agreeing a common approach to security, regulatory and infrastructure solutions. Only a standardised and collaborative approach of the industry can unlock the full potential of a secure market.
