C-DOT Collaborates with IIT Mandi and IIT Jammu to Develop Spectrum Efficiency Chip.

National

In January 2025, the Centre for Development of Telematics (C-DOT), a New Delhi-based telecom Research and Development (R&D) center under the Department of Telecommunications (DoT), Ministry of Communications (MoC), collaborated with the Indian Institute of Technology Mandi (IIT Mandi) in Himachal Pradesh and the Indian Institute of Technology Jammu (IIT Jammu) in Jammu and Kashmir to develop a chip aimed at enhancing spectrum efficiency.


      - The project is supported by the Telecom Technology Development Fund (TTDF), which promotes telecom innovations by Indian startups, universities, and research institutions to improve broadband and mobile services across India.

      - The TTDF was launched on October 1, 2022, by the Universal Service Obligation Fund (USOF) under the Ministry of Telecommunications (MoT) to support R&D efforts for technologies and products improving telecom services in rural and remote areas.

      - The agreement was signed in the presence of Dr. Raj Kumar Upadhyay, Chief Executive Officer (CEO) of C-DOT, Dr. Rahul Shrestha, Principal Investigator from IIT Mandi, Dr. Rohit B. Chaurasiya, Co-Investigator from IIT Jammu, as well as C-DOT Directors Pankaj Kumar Dalela and Shikha Srivastava.

Main Point :-   (i) The collaboration aims to develop a Wideband Spectrum-Sensor (WSS), an application-specific integrated circuit (ASIC) chip designed to optimize spectrum usage for broadband services, especially in rural areas. The project also aims to generate intellectual property (IP) for spectrum sensing technology, critical for dynamic spectrum access.

      (ii) The project will design an advanced spectrum sensing algorithm to identify unused frequency bands (spectrum holes) in communication systems, enabling interference-free operation.

(iii) The project focuses on developing hardware-efficient communication algorithms to detect underutilized frequency bands above 2 GHz, demonstrating a wideband cognitive radio module for the 6 GHz satellite band and testing designs using Field-Programmable Gate Arrays (FPGA) to improve spectrum utilization.
