The Telecom Regulatory Authority of India (TRAI) has proposed new guidelines to promote research and development in the Terahertz (THz) frequency bands, spanning from 95 GHz to 3 THz. TRAI's recommendations include the establishment of an experimental authorization called the Terahertz Experimental Authorisation (THEA). This would allow operations in these bands for a five-year term at a nominal fee of Rs 1,000, aimed at supporting technology trials and testing by Indian organizations.
In addition to THEA, TRAI suggests permitting authorization and assignment-exempt operations in several specific frequency ranges: 116-123 GHz, 174.8-182 GHz, 185-190 GHz, and 244-246 GHz. Another significant recommendation involves opening the 77-81 GHz range for automotive radar systems. This is expected to enhance the development of advanced vehicle safety features and autonomous driving technologies.
TRAI's proposal also outlines that any Indian entity—including academic institutions, research labs, government bodies, public sector units, technology parks, telecom providers, and original equipment manufacturers—will be eligible to apply for this authorization. The primary goal of these measures is to facilitate extensive experimentation and evaluation of THz technologies, paving the way for the development of next-generation wireless solutions with improved capacity and reliability.
