Nokia Siemens Networks demonstrates TD-LTE video calls in India
20 Oct 2010
Telecom network equipment supplier Nokia Siemens Networks today said it had successfully demonstrated the time division duplex version of LTE (TD-LTE) through a demonstration video call using broadband wireless access spectrum in India.
Long Term Evolution (LTE) is the next-generation mobile broadband technology and the evolutionary step from GSM, WCDMA / HSPA / HSPA+, TD-SCDMA, CDMA and WiMAX networks.
The 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.
''This is an important milestone in building the TD-LTE ecosystem in India,'' says 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.
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.
The end-to-end demonstration was based on Nokia Siemens Networks' LTE equipment and software. These include the company's Flexi Multiradio Base Station and Evolved Packet Core – which comprises Flexi NS (Network Server) and Flexi NG (Network Gateway) – and standard-compliant software.
The company said in a statement that TD-LTE technology promised enhanced delivery of broadband to laptops on the move and smartphone services, thanks to increased data rates, reduced latency and its scalable all-IP flat network architecture.
"This technology ensures high-speed mobile broadband connectivity and a superior performance from mobile applications across a wide range of devices," the statement said.
