The Telecom Regulatory Authority of India (TRAI) has released a consultation paper on open and delicensed use of unused or limited used spectrum bands for demand generation for a limited period in the terahertz range.
In the consultation paper, TRAI has sought comments from stakeholders on whether there is a need for permitting licence-exempt operations in 116-123 GHz, 174.8-182 GHz, 185-190 GHz, and 244-246 GHz frequency ranges. It has also explored if there is a need for permitting license-exempt operations in 77-81 GHz band for automotive radar applications. TRAI has asked stakeholders for the terms and conditions including technical parameters for permitting such operations in these bands, while protecting both passive and active services in and around these frequency ranges.
Further, TRAI has sought stakeholders’ views on the need to open the frequency spectrum between 95 GHz to 3 THz for experiment and demonstration of equipment designed to operate on any frequency above 95 GHz through a separate experimental licence. It has also asked if the licensees should be permitted to market experimental devices designed to operate in the frequency range between 95 GHz to 3 THz via direct sale.
TRAI has invited comments from stakeholders on the issues raised in the consultation paper by October 25, 2023 and counter-comments by November 8, 2023.
