The Telecom Regulatory Authority of India (TRAI) has proposed a new framework for experimental use of spectrum in the 95 GHz to 3 THz range, introducing what it calls the Tera Hertz Experimental Authorisation (THEA).

This initiative, prompted by a request from India’s Department of Telecommunications in December 2022, aims to stimulate research and development in emerging technologies, offering both indoor and outdoor testing opportunities,according to a press release by India’s Press Information Bureau.

TRAI's recommendations suggest that Indian entities, ranging from academic institutions to telecom service providers, should be eligible for this authorisation. The scope of THEA includes the direct sale of experimental devices operating within the specified range. The initial authorisation would last up to five years, extendable for similar periods, with a nominal fee of INR1,000 (approximately $12) for the initial term.

Moreover, TRAI has recommended that certain frequency bands, including 116-123 GHz and 244-246 GHz, be opened for operations without the need for authorisation.

Additionally, the 77-81 GHz band is set to be allocated for automotive radar systems, a move aimed at enhancing road safety in India. These proposals are part of a broader push to align India’s technological advancements with its ‘Make in India’ initiative, encouraging domestic innovation and supporting the rollout of next-generation wireless technologies.
