Cellular Vehicle-to-Everything, or C-V2X, continues to advance as the technology of choice for vehicles to communicate with each other and their environment. With the acceptance of industry standards, a series of successful tests and initial commercialization, the C-V2X holds increasing promise for increased safety, efficiency and mobility on the road. This is particularly important for the future use of non-line-of-sight sensors for autonomous vehicles, as it paves the way for the next generation of transportation.
So what is C-V2X?
C-V2X is a technology that allows vehicles to communicate with each other and with virtually everything around them (V2X). It is designed to support the safer and more autonomous vehicles of the future, while improving traffic flow and the safety of vehicle occupants, pedestrians, and cyclists. C-V2X helps vehicles communicate wirelessly vehicle-to-vehicle (V2V) and, perhaps one day, vehicle to pedestrian (V2P), which could greatly improve collision avoidance systems. In addition to communicating with other road users, C-V2X enables the vehicle to communicate with the larger Vehicle to Network (V2N) to access real-time traffic or routing services via services on the road. cloud. Cars don't just broadcast their location, speed, and direction. By using vehicle-to-infrastructure (V2I) technology, cars can be coordinated with complex maneuvers. Also, by communicating with traffic signals, cars can time a trip with green lights to avoid delays and downtime. Vehicles can even communicate with each other to create space for more cars on the road, improving fuel economy, congestion and emissions.How 5G could take the C-V2X to the next level
Combined with 5G network capabilities, vehicles can share rich data in real time and support fully autonomous driving experiences, which could improve road safety and traffic efficiency. Managing urgent decision-making processes in the car requires low-latency data exchange with external sources, such as surrounding objects, as well as access to edge computing capabilities. 5G offers such communication along with high performance, allowing embedded compute engines to access remote sources and exchange data in an efficient and highly efficient manner. The 2-degree C-V360X systems can be used to detect potential collision objects and, when combined with new data, interchange warning systems between ultra-reliable vehicles and critical safety decisions such as whether both vehicles can instantly take braking. automatic. Modern technology with superior radio performance, the C-V2X is capable of providing improved range and reliability for low latency direct communication. Unlike other communication technologies, C-V2X combines direct and network-based technologies synergistically. The C-V2X does not need cellular networks to provide direct communication for local mobility and security services. In many parts of the world, regulators have delineated network frequency bands for intelligent transportation systems (ITS), particularly the 5,9 GHz spectrum for safety-critical road ITS communications between vehicles, infrastructure, and people. Coexistence within 3GPP technologies allows integration in future technological advances. 5G V2X (3GPP R16 and above) devices offer additional ITS functionality to those of LTE-V2X (3GPP Rel-14/15) and are also designed to coexist seamlessly so that, just like the smartphone, the Older and newer generations can be integrated into the same vehicle.What's next for C-V2X?
C-V2X is probably the only V2X technology with a clear evolution path towards 5G, and should be ready for commercial vehicle deployment within a year. The maturity of the technology has conquered many car manufacturers, including Ford in the United States and multiple car suppliers in China. Highway operators in each of these countries have also begun to deploy C-V2X road units, and the regions are aligning their connected vehicle efforts with the ETSI TC ITS TS 103097 specification safety services standard to ensure safety. and protection. optimal efficiency. A vision emerging from the automotive industry is not just to get from point A to point B, 5G roads may take a different shape with the advent of automation, as 5G is expected to fundamentally change the way we think about people. transportation networks. Data could be transmitted between points along intelligent routes, with speed and in large volumes. Network connectivity and reliable coverage are crucial for the future development of autonomous vehicles. Improved data capture and connectivity can help overcome one of the biggest barriers to autonomous vehicle adoption: public trust. C-V2X technology could increase public confidence that remote-controlled vehicles are designed to be safe. We are excited about the adoption of C-V2X globally, paving the way for the next generation of transportation and striving to make our roads safer and smarter.- Enrico Salvatori, Senior Vice President and President of Qualcomm Europe.
