The Voice 2
Prof. Radhakrishna Ganti, Department of Electrical Engineering, IIT Madras, said, “I am honoured to receive the Rashtriya Vigyan Puraskar Award for my work in wireless and cellular systems.
I am grateful that my work in developing and building wireless systems is recognized and I hope that it would encourage more researchers and faculty to do systems work, he said.
Prof further said he had the privilege of working with excellent researchers who have helped me at various stages to significantly contribute to the vision of India-led wireless standards and lay the foundation for an indigenous wireless ecosystem in India.
I want to thank my mentors, teachers, colleagues and friends who encouraged me to pursue what I enjoyed and helped me along the way, he said.
I wish to express my sincere gratitude to Prof. Bhaskar Ramamuthi and Prof. V. Kamakoti as well as the entire IIT Madras administration for their excellent support throughout the years and for their invaluable advice.
I deeply appreciate the support of MeiTY and DOT for their financial grants as well as their steadfast support in the development of indigenous technologies and standards, he said.
I want to thank my parents for their belief and confidence in me and my in-laws for their constant support.
My special thanks to my wife Sambhavi and my son Eswar Prakash who always stood with me, supported me through the journey and share my dream and passion for Atmanirbhar Bharath, he said.
About Prof Prabhu Rajagopal

About Prof Radhakrishna Ganti
Prof. Radhakrishna Ganti has been working in the area of wireless and cellular communications for the last 11 years as a faculty in the Department of Electrical Engineering, IIT Madras.
He is an expert in the area of wireless system design, 5G cellular systems, wireless hardware systems, and stochastic geometry.
He has built a state-of-the massive-MIMO radios and its associated software towards indigenisation efforts.
Prof. Radhakrishna has been continuously working with DRDO (and other defence organisations) and helping them develop local capabilities in wireless communications.
An example of this is the Tropo-scatter OFDM modem designed, developed and tested (by him and two of his colleagues) which has been manufactured and now is being used by armed forces.
In fact, from importing troposcatter modems, India is now exporting these modems to other countries
His Research Contributions include
1) Application of stochastic geometry to the analysis of wireless networks
2) Development of key technologies like full-duplex, pilotless Massive MIMO systems and newer algorithms and architectures for 5G and 6G systems
3) Instrumental in driving the Low Mobility Large Cell (LMLC) requirement in ITU which focused on improving rural coverage
4) Development of indigenous 5G systems (hardware and software) in collaboration with other IITs and other research institutions.
This technology has been transferred to companies for commercialization.
The 5G infrastructure (hardware and software) developed at IIT Madras is a state-of-the art system and provides a basis for starts-ups and smaller companies in India to build their 5G products.
Prof. Radhakrishna Ganti’s future goals include working on the development of next-generation wireless systems like 6G with an emphasis on AI/ML and the development of systems to meet the Indian requirements in commercial and defense applications.
