TRAI Recommends THEA to Boost 6G and Next-Gen Wireless Tech in India
In a significant move toward advancing next-generation wireless technologies, the Telecom Regulatory Authority of India (TRAI) has recommended the introduction of the Tera Hertz Experimental Authorisation (THEA) to the government. This initiative is designed to stimulate research and development in the high-potential Tera Hertz frequency band, a critical element for future wireless communication technologies, including 6G.
TRAI released its recommendations for the Tera Hertz Spectrum in response to a December 2022 request from the Department of Telecommunications (DoT). The DoT sought advice on utilizing underused or sparsely used spectrum bands in the Tera Hertz range for limited periods to drive innovation and demand. THEA aims to facilitate R&D, indoor and outdoor testing, technology trials, experimentation, and demonstrations in the 95 GHz to 3 THz range.
The unique properties of the Tera Hertz frequency band make it particularly valuable for emerging technologies. By enabling faster data transmission speeds, improved connectivity, and enhanced reliability, these frequencies could play a transformative role in sectors ranging from telecommunications to automotive and healthcare.
“The purpose of THEA should be to promote R&D, indoor and outdoor testing, technology trial, experimentation, and demonstration in the 95 GHz to 3 THz range”, TRAI stated in its recommendations. The plan is expected to empower entrepreneurs, startups, and academic institutions to explore the untapped potential within this high-frequency spectrum.
TRAI has proposed a five-year authorisation period for THEA, with the possibility of extending it for an additional five years. Innovators can obtain this authorisation by paying a nominal fee of 
1,000, making the program accessible to a broad range of stakeholders. Eligible applicants include academic institutions, R&D labs, government entities, telecom service providers, original equipment manufacturers, and more.

The authorisation covers multiple frequency bands, including 116-123 GHz, 174.8-182 GHz, 185-190 GHz, and 244-246 GHz. Specific provisions are also included for automotive radar systems within the 77-81 GHz range, demonstrating the broad applicability of THEA across various industries.
Experts anticipate that THEA will substantially enhance India’s technological landscape by enabling hands-on experimentation, critical for assessing product viability and performance during early development phases. TRAI noted that this initiative will also complement the government’s “Make in India” initiative, driving domestic innovation and manufacturing.
“Upon implementation, the new experimental authorisation regime recommended by the Authority will provide a boost to the 'Make in India' initiatives of the Government”, TRAI added. The initiative aligns with the government’s broader vision of nurturing a culture of innovation and research across the nation.
By fostering the development of advanced solutions, India aims to bolster its technological prowess and contribute to global advancements. As high-frequency technologies gain prominence worldwide, THEA could elevate India’s position on the global tech stage, accelerating the adoption of 6G and other cutting-edge innovations.
