Finnish telecom equipment maker Nokia has inaugurated its new research and development (R&D) facility for fixed networks in Siruseri, Chennai. The facility, the largest of its kind globally, reflects Nokia’s deepening presence in Tamil Nadu and its commitment to advancing broadband and optical network technologies.
Expansion Following Government MoU
The expansion follows a Memorandum of Understanding (MoU) signed between Nokia and the Tamil Nadu government during Chief Minister M.K. Stalin’s visit to the United States in August 2024. Tamil Nadu Industries Minister T.R.B. Rajaa shared details of the project on social media, highlighting the creation of over 200 high-end jobs through the new facility.

Investment and Project Phases
The first phase of the project will involve an investment of ₹270 crore, higher than the initially planned ₹220 crore. The second phase is expected to cost around ₹300 crore. The facility is designed to focus on advanced fixed network broadband technologies, serving as Nokia’s largest global lab for fixed network R&D.
Global Testbed for Advanced Technologies
The Siruseri facility will also act as a global testbed for innovations in optical networks, including 10G, 25G, 50G, and 100G technologies, as well as fixed wireless access (FWA) and other emerging broadband solutions. Nokia aims to leverage this facility to develop next-generation telecom infrastructure and network solutions.
Nokia’s Presence in Tamil Nadu
Nokia has long been a significant R&D investor in Chennai, employing close to 1,000 engineers in the state. The company is integrated into the local telecom and network engineering ecosystem, contributing to innovation and technological growth.
Strengthening 5G and Telecom Partnerships
In India, Nokia continues to maintain commercial partnerships with major telecom operators, including Reliance Jio, Bharti Airtel, and Vodafone Idea, particularly in the 5G radio access network (RAN) space. The new R&D facility is expected to further strengthen these collaborations and support global innovations in fixed network technologies.
