Building a robust telecom infrastructure has become a necessity for countries as they look for ways to empower citizens with communications access.
Citing India's prowess in software services, laying down digital infrastructure, and design capabilities, Sundararajan said the country is keen to share technology, training expertise, and know-how with other nations that face "similar challenges".
