India stands on the precipice of a significant transformation in its transportation landscape, with the government actively formulating the foundational regulatory framework for Vehicle-to-Everything (V2X) communication. This ambitious undertaking, aimed at ushering in an era of intelligent transport systems (ITS) and connected vehicles, hinges critically on the judicious allocation and management of radio spectrum. At the heart of this initiative, the Department of Telecommunications (DoT) has entrusted the Telecom Regulatory Authority of India (Trai) with the crucial mandate of recommending a comprehensive regulatory structure for spectrum assignment and pricing. This move signals a pivotal shift from conceptual discussions to concrete policy, laying the groundwork for the invisible digital infrastructure that will underpin a safer, more efficient, and economically dynamic mobility ecosystem.
The essence of V2X technology lies in its capacity for real-time, low-latency communication between vehicles and their environment. This sophisticated network comprises two primary components: On-Board Units (OBUs) integrated into vehicles, and Roadside Units (RSUs) strategically deployed along physical infrastructure such as traffic signals, highway gantries, and intelligent road signage. OBUs facilitate direct communication between vehicles (V2V), enabling collision avoidance warnings, traffic jam alerts, and cooperative maneuvering. Simultaneously, they interact with RSUs (V2I), which act as digital conduits, relaying critical information from the road infrastructure about hazards, traffic flow, construction zones, and even dynamic speed limits. This intricate interplay extends to Vehicle-to-Network (V2N) and Vehicle-to-Pedestrian (V2P) communications, creating a holistic data-sharing environment that transcends a driver’s line of sight and enhances situational awareness for all road users. The DoT’s foresight in reserving a dedicated 50MHz spectrum in the 5,875–5,925 megahertz (MHz) band for V2X and ITS applications, with 30MHz earmarked for initial deployment and the remainder for future expansion, underscores the strategic importance placed on this digital backbone. This specific frequency band is globally recognized for its suitability for V2X, offering a balance of propagation characteristics and capacity essential for safety-critical, high-throughput applications.
The regulatory approach being deliberated by Trai is multi-faceted, reflecting the diverse nature of V2X components and their deployment models. For in-vehicle devices (OBUs), the prevailing global trend, and indeed the current proposal under consideration, leans towards permitting licence-exempt use. This strategy offers significant advantages: it reduces the regulatory burden on vehicle manufacturers, accelerates the integration of V2X capabilities into new vehicles, and promotes wider adoption by lowering potential compliance costs. Automakers would thus be able to embed these communication modules without needing individual spectrum licences, fostering innovation and competitive pricing. Conversely, for Roadside Units (RSUs), the government is exploring a mechanism of administrative allocation for spectrum. This non-auction-based approach is justified by the public good nature and safety-critical function of RSUs. These units are integral to national infrastructure, providing essential services like accident prevention, traffic management, and emergency response. Consequently, the proposal suggests that state governments or agencies designated by the National Highway Authority of India (NHAI) would be authorized to deploy and manage RSUs, acquiring spectrum on an administrative basis to ensure reliability and minimize interference in these crucial public safety applications. This two-tiered licensing strategy aims to balance ease of adoption for private entities with robust control and coordination for public infrastructure.
The economic and societal implications of a fully operational V2X ecosystem in India are profound. With the country grappling with alarmingly high road accident rates—recording 487,705 accidents and 177,177 fatalities in 2024, as per Ministry of Road Transport and Highways (MoRTH) data—the deployment of V2X technology aligns directly with India’s commitment to the Stockholm Declaration, pledging to halve road deaths and injuries by 2030. V2X systems can provide instantaneous warnings for impending collisions, pedestrian presence, sharp curves, and adverse weather conditions, significantly reducing human error, which is a leading cause of accidents. Beyond safety, V2X holds immense potential for alleviating traffic congestion, a perennial challenge in India’s rapidly urbanizing landscape. By enabling dynamic traffic light optimization, intelligent route guidance, and real-time incident management, V2X can reduce travel times, lower fuel consumption, and cut carbon emissions, contributing to both economic efficiency and environmental sustainability. Studies suggest that urban congestion costs major economies billions annually in lost productivity and wasted fuel; V2X offers a technological pathway to reclaim a substantial portion of this economic leakage.
From an industry perspective, the automotive sector in India is poised for this technological leap. Automakers have already made significant strides in integrating Advanced Driver Assistance Systems (ADAS) into their vehicles, and V2X is widely considered the logical next evolution. As Hemal Thakkar, director at Crisil Intelligence, rightly notes, "Delayed regulation could lead to technology lock-in or fragmentation, especially if OEMs adopt proprietary or global standards without localization." Indian original equipment manufacturers (OEMs) are "directionally ready," with some, like Mahindra, already advertising V2X capabilities in their future models, albeit pending regulatory clearance. The initial phase of V2X deployment is expected to be largely driven by public investment, given that its primary benefits—enhanced road safety, reduced congestion, and improved efficiency—are public goods. However, the long-term vision extends far beyond, envisioning a rich "service layer" that will unlock new commercial opportunities. This includes predictive maintenance alerts, sophisticated traffic intelligence for logistics and ride-sharing platforms, dynamic insurance models based on driving behavior and road conditions, and optimized fleet management. This transition from a public safety utility to a commercial service platform represents a significant economic opportunity, fostering innovation in software, data analytics, and mobility solutions.
India’s journey towards intelligent transport systems has been methodical. In September 2024, the MoRTH established a dedicated task force for the development and implementation of ITS, with a specific focus on V2X communications. This multi-stakeholder body, comprising representatives from the Automotive Research Association of India (ARAI), the Society of Indian Automobile Manufacturers (SIAM), the Cellular Operators Association of India (COAI), the Telecommunication Engineering Centre (TEC), the DoT, and NHAI, reflects a coordinated approach. The task force’s recommendations, including the crucial advocacy for licence-exempt in-vehicle devices and localized oversight for RSU installations by state governments or NHAI, have been instrumental in shaping the current regulatory discourse. Their final report, submitted to MoRTH in January, further emphasized the critical need for pilot projects and interoperability across states, recognizing the diverse jurisdictional landscape of road infrastructure in India.
Globally, the race for V2X leadership is accelerating. China has aggressively rolled out V2X infrastructure on major highways and urban corridors, integrating it into its smart city initiatives. European countries are actively conducting trials across various urban and highway environments, often exploring both dedicated short-range communication (DSRC) and cellular V2X (C-V2X) technologies. The United States has seen significant pilot programs and ongoing debates regarding spectrum allocation, while Japan and South Korea are steadily equipping new vehicles and modernizing their road networks with V2X capabilities. India’s coordinated effort to define its regulatory and operational framework is crucial to avoid fragmentation and ensure seamless integration with emerging global standards.
As India moves forward, several challenges must be addressed. Securing adequate funding for RSU deployment, ensuring nationwide interoperability across different states and manufacturers, establishing robust cybersecurity protocols for safety-critical systems, and navigating data privacy concerns associated with extensive vehicle data collection will be paramount. A cohesive national strategy, harmonizing spectrum policies with road infrastructure development and data governance, is essential to fully realize the transformative potential of V2X. By meticulously crafting this regulatory backbone, India can not only mitigate its pressing road safety crisis and ease urban congestion but also position itself as a global leader in intelligent mobility, fostering innovation, creating new economic opportunities, and enhancing the quality of life for its citizens. The connected car in the driveway, once a futuristic vision, is rapidly becoming a tangible reality, with India’s regulatory architects diligently charting its path to widespread adoption.
