Samsung Electronics and Nokia Siemens Networks have successfully conducted what it claims to be the first TD-LTE data call using a prototype end-user device. The demonstration proved the interoperability of Nokia Siemens Networks' end to end TD-LTE network solution with Samsung's TD-LTE USB dongle.

The trialing of TD-LTE data calls, which can be used for high-definition video services, was conducted at Nokia Siemens Networks' R&D Center in Hangzhou, China. The call employed the company's TD-LTE infrastructure, comprising both the Flexi multiradio base station and the company's core network solution, including the Flexi NS (Network Server) and the Flexi NG (Network Gateway)all using LTE software compliant with the 3GPP March 09 baseline specifications. TD-LTE devices from Samsung were used proving the interoperability between them and the network. TD-LTE is the variant of LTE for unpaired spectrum expected to be deployed by operators such as China Mobile.

"As the evolutionary path for China Mobile's 3G TD-SCDMA networks, as well as an option for other operators around the world who have available unpaired spectrum, TD-LTE is one of the important global standards. As a leader in next-generation mobile technology, we see it as a great growth opportunity," said Byung-Duck Cho, executive VP of Samsung's R&D center. "This demonstration ensures the cohesive development of our devices for the roll-out of TD-LTE technology at a quicker pace."

"This is an important milestone in building the TD-LTE ecosystem," said Marc Rouanne, head of Nokia Siemens Networks' business unit. "This successful data call demonstrates the end-to-end interoperability of TD-LTE network and device equipment. It also shows our global commercial readiness for deployments of TD-LTE, expected in the second half of 2010."

In October 2009, Nokia Siemens achieved the first TD-LTE data call on its Flexi multiradio base station with fully standards-compliant software. Moreover, in April of this year, the company inaugurated the industry's first TD-LTE open lab in its Hangzhou Development Center, providing an end-to-end testing environment to verify the compatibility of terminals and devices with the company's TD-LTE network products and solutions.
