Nokia Siemens Networks is the first company to successfully demonstrate the Time Division Duplex version of LTE (TD-LTE) using broadband wireless access (BWA) spectrum in India.

The first video call was made by Gurdeep Singh, chief operating officer of Aircel. The call was conducted with the 4G mobile technology running on commercial hardware at the Nokia Siemens Networks’ Bengaluru R&D facility. It marks an important milestone moving 2.3 GHz TD-LTE closer to commercial availability.

During the test, Nokia Siemens Networks demonstrated high-definition video streaming and three-way video conferencing. Using interoperable TD-LTE dongles from Samsung, the demo showcased a peak throughput speed of 110 megabits per second (Mbps) and low latency in the range of 10-20 milliseconds.

“Today’s demo reiterates our leadership and commitment to getting TD-LTE into new market. It also demonstrates our regional and global progress in this area,” said Juha Lappalainen, head of mobile broadband sales at Nokia Siemens Networks. “Our TD-LTE trials across the globe prove our capability in driving rapid commercial TD-LTE network deployments aimed at facilitating a new wave of advanced mobile broadband services.”

“This is an important milestone in building the TD-LTE ecosystem in India,” added Urs Pennanen, head of India region, Nokia Siemens Networks. “TD-LTE over the Broadband Wireless Access 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.”
