TD-LTE ecosystem reaches maturity with landmark data call


Hangzhou, China - Samsung and Nokia Siemens Networks collaborate on world’s first end-to-end TD-LTE data call

Marking an important milestone in TD-LTE commercialization, Samsung and Nokia Siemens Networks have successfully conducted the world’s 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 award-winning 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 vice president of Samsung Electronics’ 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’ Network Systems 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 Networks 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.

Notes to Editors

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. It promises the delivery of broadband and smart device services thanks to increased data rates, reduced latency and a scalable flat all-IP network architecture. Nokia Siemens Networks is the frontrunner in LTE, being the first to make an LTE call using commercial hardware and standard compliant software in September 2009.

Nokia Siemens Networks has a long track record in demonstrating its technological leadership in LTE:

* November 2006 Nokia Siemens Networks conducted the world’s first LTE demo with a handover to HSPA at the ITU World Congress in Hong Kong
* September 2008 Nokia Siemens Networks shipped the industry’s first LTE base station hardware to customers.
* November 2008 Nokia Siemens Networks conducted the world’s first demonstration of LTE-Advanced Relaying technology.
* September 2009 Nokia Siemens Networks made the world’s first LTE call using a commercial base station and fully standards-compliant software (3GPP Rel 8 March 09 baseline).
* September 2009 Nokia Siemens Networks conducted with China Mobile the world’s first TD-LTE femtocell demonstration
* October 2009 Nokia Siemens Networks made the world’s first LTE handover test using a commercially available base station and fully standards-compliant software (3GPP Rel 8 March 09 baseline).
* October 2009 Nokia Siemens Networks conducted the world’s first TD-LTE call using its Flexi Multiradio base station and fully standards-compliant software (3GPP Rel 8 March 09 baseline).
* October 2009 Nokia Siemens Networks conducts end-to-end LTE interoperability testing with four leading device vendors across several frequency bands.
* November 2009 Nokia Siemens Networks is a founding member of the One Voice initiative providing a blueprint for the early deployment of IMS-based Voice over LTE service. The company’s Fast Track approach is fully compliant with One Voice.
* December 2009 Nokia Siemens Networks rings up another first in LTE with 3GPP standardized voice over LTE calls. Successful IMS-compliant voice calls and SMS messaging using standardized LTE equipment marks an important step towards commercial voice over LTE deployments.
* March 2010 World’s first call between different VoLTE clients showcased at CTIA 2010. Nokia Siemens Networks demonstrates standards-based Voice over LTE (VoLTE) interoperability using two different clients running on Samsung LTE devices
* April 2010 Nokia Siemens Networks sets up industry’s first TD-LTE Open Lab. Provides smart phone and terminal testing facility to accelerate TD-LTE ecosystem
* April 2010 Nokia Siemens Networks commences production of Flexi Base Stations in the 800 MHz frequency band to enable countrywide LTE rollouts
