Chipset platform provider, Sequans and Nokia Siemens Networks (NSN) announced the successful interoperability trials of TD-LTE technology in the 2.3 GHz, 2.5 Ghz and 2.6 Ghz frequency bands. The demonstration tested the interoperability of Nokia Siemens Networks’ TD-LTE infrastructure equipment with Sequans’ SQN3010 platform*.

The TD-LTE interoperability trial was conducted at Nokia Siemens Networks’ R&D center in Hangzhou, China. The Open Lab in Hangzhou can be used by major TD-LTE smartphone and terminal manufacturers around the world to test the interoperability and functionality of their devices across TD-LTE networks. During the recent interoperability testing, Nokia Siemens Networks used its standard-compliant TD-LTE infrastructure solution comprising the award-winning Flexi Multiradio Base Station and its core network solution including the Flexi NS (Network Server) and the Flexi NG (Network Gateway).

“Sequans has leveraged its leadership in the WiMAX market to become one of the first to deliver a TD-LTE chip solution, enabling TDD operators worldwide,” said Craig Miller, vice president of marketing and business development, Sequans. “We are focused intently on the development of a robust TD-LTE ecosystem that includes global infrastructure vendors such as Nokia Siemens Networks.”

“These trials are extremely important for network operators with TDD spectrum assets, particularly in China, India and Japan as well as other regions including Europe, where TDD licenses in the 2.6 GHz spectrum have been awarded recently,” said Thorsten Robrecht, head of LTE product management, Nokia Siemens Networks. “Performing the test with Sequans’ chipset that is targeted for use in TD-LTE trials across China, India and Japan will thus speed up the commercialization of TD-LTE.”
