NSN has tested LTE (TD-LTE), or the fourth generation (4G) mobile technology, using broadband wireless access (BWA) spectrum in India, the company said in a statement.
Industry observers say that as TD-LTE moves closer to commercial availability, it is likely to spoil the case for rival WiMax technology, which also uses BWA spectrum.
During the test, NSN demonstrated high-definition video streaming and three-way video conferencing.
"This is an important milestone in building the TD-LTE ecosystem in India," said Urs Pennanen, NSN's head of India region.
"TD-LTE over the BWA spectrum is important for the country, as it will allow operators to offer voice and data to the masses. We are ready to collaborate with partners to accelerate our progress toward a comprehensive deployment of TD-LTE in India."
