TRAI Releases Consultation Paper on V2X Communication to Boost Emerging Telecom Technologies in India

The Telecom Regulatory Authority of India (TRAI) has issued a consultation paper to develop a regulatory framework for Vehicle-to-Everything (V2X) communication.V2X is an advanced communication technology that enables vehicles to connect with other vehicles, road infrastructure, pedestrians, and networks. Its main objective is to improve road safety, make traffic management smarter, and reduce accidents.

¨    The consultation paper seeks stakeholder inputs on key issues such as spectrum allocation, licensing models, interoperability standards, and security frameworks required for V2X deployment.

¨ It identifies the 5.9 GHz spectrum band—globally earmarked for V2X—as a potential candidate for India’s implementation strategy.

¨ It reflects the growing importance of 5G-enabled communication systems in enhancing road safety and enabling future autonomous mobility.

Key Features of the Proposed Regulatory Framework

¨ Spectrum Management and Technology Choice: The framework examines optimal utilisation of the 5.9 GHz band and evaluates technology options such as Cellular V2X (C-V2X) technology for reliable and low-latency communication.

¨     Infrastructure and Ecosystem Development: It emphasises the deployment of on-board units (OBUs) in vehicles and roadside units (RSUs) to facilitate seamless communication and real-time alerts.

¨ Interoperability and Standardisation: The need for common standards and interoperability across devices, networks, and regions is highlighted to ensure the seamless functioning of V2X systems.

¨  Security, Privacy, and Liability: The framework addresses concerns related to cybersecurity, data privacy, and legal liability, which are critical for safe and trustworthy deployment.

V2X Communication

¨  Vehicle-to-Everything (V2X) communication refers to the exchange of real-time information between vehicles and their surrounding environment, enabling intelligent decision-making.

¨     It enables vehicles to detect hazards “beyond line of sight” through wireless alerts and data exchange (e.g., speed, location, traffic signals, and collision warnings), thereby significantly improving road safety.

It includes multiple communication modes such as

¨     Vehicle-to-Vehicle (V2V)

¨     Vehicle-to-Infrastructure (V2I)

¨     Vehicle-to-Pedestrian (V2P)

¨     Vehicle-to-Network (V2N)

While early V2X systems relied on Dedicated Short-Range Communications (DSRC), there is a growing shift toward Cellular V2X (C-V2X) due to its ability to leverage 4G/5G networks, offer wider coverage, and integrate more seamlessly with existing telecom infrastructure.

Significance of V2X Communication

¨     Enhancing Road Safety: V2X enables real-time alerts regarding collisions, road hazards, and traffic conditions, significantly reducing accidents.

¨   Improving Traffic Efficiency: It facilitates smart traffic management, congestion reduction, and route optimisation, improving urban mobility.

¨ Enabling Autonomous Vehicles: Reliable communication is essential for autonomous driving systems, making V2X a foundational technology for future mobility.\

¨  Strengthening Digital Ecosystem: It boosts demand for 5G infrastructure and digital connectivity, contributing to India’s broader digital transformation.
