Nokia has expanded its presence in Tamil Nadu by opening the world's largest research and development facility dedicated to fixed networks. Located in SIPCOT Siruseri, Chennai, this new hub signifies a major advancement for the state's telecommunications industry. The facility is poised to be a global testing ground for innovations in high-speed optical networks, including 10G, 25G, 50G, and 100G technologies, as well as fixed wireless access.
The establishment of this facility stems from a Memorandum of Understanding signed during Chief Minister M. K. Stalin's visit to the United States in August 2024. This commitment has now materialized into a substantial investment. Nokia's initial phase of investment has been elevated to ₹270 crore, surpassing the original ₹220 crore projection. A second phase is anticipated to bring an additional ₹300 crore investment.
This development is expected to generate over 200 high-end employment opportunities within Tamil Nadu. The Siruseri center will house Nokia's most extensive fixed network R&D laboratory globally, focusing on developing next-generation fixed broadband technologies. This strategic move reinforces Tamil Nadu's status as a preferred destination for deep-tech and engineering endeavors worldwide.
