A key step towards advancing next-generation wireless technology: Telecom Regulatory Authority of India (TRAI) It is recommended to introduce Terahertz Experimentation Authorization (THEA) Proposal for the Government: This initiative aims to promote research and development into the high-potential terahertz frequency band, which is a key component of future wireless communication technologies, including 6G.
TRAI issued the recommendations on the terahertz spectrum in response to a request from the Department of Telecommunications (DoT) in December 2022. The DoT had sought advice on using underutilised or sparsely used spectrum bands in the terahertz range for a limited period to spur innovation and demand. The THEA aims to encourage research and development, indoor and outdoor testing, technology trials, experiments and demonstrations in the 95 GHz to 3 THz range.
The unique properties of the terahertz frequency band make it especially valuable for emerging technologies: By enabling faster data transmission speeds, improved connectivity and enhanced reliability, these frequencies have the potential to play a transformative role in a wide range of sectors from communications to automotive to healthcare.
“The objective of THEA is to facilitate research and development, indoor and outdoor testing, technology trials, experiments and demonstrations in the 95 GHz to 3 THz range,” TRAI said in its advisory. It is hoped that the scheme will enable entrepreneurs, start-ups and academic institutions to explore the untapped potential within this high frequency spectrum.
TRAI has proposed to grant the THEA for a period of five years, with the possibility of extending it for another five years. Innovators can obtain the approval by paying a fee of just $100. 
With 1,000 participants, the program is open to a wide range of stakeholders. Eligible applicants include academic institutions, R&D labs, government agencies, communication service providers, OEMs, etc.
The authorization covers multiple frequency bands including 116-123 GHz, 174.8-182 GHz, 185-190 GHz, and 244-246 GHz. It also includes specific provisions for automotive radar systems in the 77-81 GHz range, demonstrating the broad applicability of THEA across various industries.
Experts expect THEA to significantly strengthen India’s technology landscape by enabling hands-on experimentation, which is essential to assess the feasibility and performance of products at the early stages of development. TRAI noted that the initiative will also complement the government’s “Make in India” initiative and boost domestic innovation and manufacturing.
“If the new experimental licensing system recommended by the authorities is implemented, “Make it in India” “This is part of the government’s initiative, which is in line with the government’s broader vision of fostering a culture of innovation and research across the country,” TRAI added.
India aims to strengthen its technological capabilities and contribute to global progress by fostering development of advanced solutions. As radio frequency technology gains prominence across the globe, THEA India’s position in the global technology worldAccelerate the adoption of 6G and other cutting-edge innovations.
