As per findings from WiseGuy Reports, the connected vehicle roadside unit market is being propelled by advancements in communication technologies. The connected vehicle roadside unit communication link is the vital wireless connection that enables the exchange of data between vehicles and infrastructure, forming the foundation for a wide range of safety, mobility, and environmental applications.
The primary communication technologies for RSUs include Dedicated Short-Range Communications (DSRC), Cellular Vehicle-to-Everything (C-V2X), and Satellite Communications. DSRC, a mature standard based on Wi-Fi technology, operates in the 5.9 GHz band and offers low latency and reliable short-range communication, ideal for safety-critical applications like collision avoidance. C-V2X, which includes both direct communication (PC5) and network-based (Uu) interfaces, leverages cellular networks and is poised to become the dominant technology, offering higher data rates, better range, and the ability to integrate with the broader 5G ecosystem. Satellite communications complement these by providing coverage in remote areas.
The integration of 5G networks is revolutionizing this communication landscape. 5G's enhanced data transmission speeds and low latency enable more reliable V2X communication, supporting advanced applications such as autonomous driving and real-time traffic management. The Global System for Mobile Communications Association (GSMA) has noted that by 2025, 5G will cover around 65% of the global population, enriching the potential for connected vehicle technologies. Major telecommunications companies rolling out infrastructure is opening further opportunities for RSU installation.
Key industry developments highlight the strategic importance of this communication link. Bosch's January 2024 major contract win to supply RSU hardware and a secure V2X software stack for a nationwide C-ITS rollout in a European country demonstrates the increasing scale of deployments. As the market grows, the focus on developing robust cybersecurity protocols tailored to connected vehicle communications is becoming critical to ensure trust and compliance in data exchanges. The connected vehicle roadside unit market will continue to evolve with these communication technologies, enabling a future of seamless, connected mobility.
