Sequans and Nokia Siemens Networks have successfully conducted TD-LTE interoperability trials 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. During the recent interoperability testing, Nokia Siemens Networks used its standard-compliant TD-LTE infrastructure solution comprising the 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.

“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. 

Earlier this year, Nokia Siemens Networks successfully demonstrated TD-LTE trials during Shanghai World Expo, and TD-LTE data calls at the company’s R&D center in Hangzhou and at Taiwan’s National Chiao Tung University.
