TL;DR
India's DoT has de-licensed the 77-81 GHz band for automotive radars, simplifying ADAS feature development by removing spectrum assignment requirements.
In a significant development for the automotive industry, India's Department of Telecommunications (DoT) has de-licensed the 77-81 GHz frequency band for short-range automotive radar systems. This move exempts these radars, widely used in advanced driver-assistance systems (ADAS) features, from the spectrum assignment rule, thereby streamlining the process for their development and deployment in the country.
The notification, issued on November 26, 2025, specifies that no frequency assignment will be required for establishing or operating wireless equipment for short-range automotive radar systems within this band. However, these systems must adhere to certain technical parameters, ensuring non-interference, non-protection, and shared (non-exclusive) usage. This deregulation is expected to significantly accelerate the growth of autonomous vehicle technologies and enhance safety features in Indian cars.
