11 Qorvo 2022 There are many components of V2X (see sidebar) "Vehicle Communications Acronyms + Meanings"). Enhancing V2X and bringing it to market is often a top priority for many car manufacturers because of the many safety benefits, as well as other communication benefits for the consumer. However, to design a robust system solution, we need to first understand the intricacies and challenges of V2X. Cellular-V2X (C-V2X) brings several vehicle engineering challenges such as wireless coexistence caused by multiple radios inside and outside the vehicle. The new and future automobile will have many radios inside to address safety, security, and entertainment trends. These radios will lead to co-existence challenges. One obvious coexistence challenge is Dedicated Short-Range Communications (DSRC) and C-V2X (Cellular operators licensed carrier), which communicate using the same 5.9GHz band. Additionally, 4G LTE, 5G and Wi-Fi all have bands closely aligned with the 5.9GHz frequency range. Future automobile trends There are numerous, unique connectivity technologies in the connected vehicle, and they must not interfere with each other's signal quality to achieve seamless communication. These technologies include: • V2X (DSRC and C-V2X) used for automobile safety • 4G/5G cloud connectivity for in-vehicle OEM services such as remote diagnostics, over-the-air software updates, teleoperation, and more • In-vehicle 4G/5G cloud connectivity entertainment • Wi-Fi • Bluetooth® • Satellite digital audio radio services (SDARS) Vehicle-to-Everything (V2X): A technology that allows vehicles to communicate with moving parts of the traffic system around them. Vehicle-to-Infrastructure (V2I): Communication that allows vehicles to share information with traffic system components such as overhead RFID readers and cameras, traffic lights, lane markers, streetlights, signage, and parking meters. Vehicle-to-Pedestrian (V2P): Communications between a vehicle and a pedestrian or multiple pedestrians within close proximity. Vehicle-to-Network (V2N): Communication with, and access to, networks for cloud-based services. Cellular Vehicle-to-Everything (C-V2X): Allows vehicles to communicate via mobile cellular connectivity to send and receive signals from a vehicle to other vehicles, pedestrians, or to fixed objects such as traffic lights in its surroundings. Dedicated Short-Range Communications (DSRC): One-way or two-way short-range to medium-range wireless communication channels specifically designed for automotive use and a corresponding set of protocols and standards. ▲ Why Qorvo should be your automotive design partner Vehicle Communications Acronyms + Meanings V2X communication technology promises to lower the number of vehicle accidents, which will also lead to a reduction in associated injuries and deaths.
