Nokia Siemens Networks (NSN) will extend its LTE technology portfolio to support the 1.9GHz frequency bands, in a move that will enable operators to re-farm existing1.9GHz spectrum to provide LTE services.

The vendor is upgrading its Flexi Multiradio 10 Base Station to support 1.9GHz TD-LTE and will be conducting  trials of its capabilities in China. The offering is expected to be commercially available by Q4 2012, NSN said.

The capability was first introduced at a customer event for China Mobile, which has specific plans to evolve its TD-SCDMA network to dual-mode, supporting both TD-SCDMA and TD-LTE services in the 1.9GHz band.

“TD-LTE provides a much faster and highly responsive mobile internet experience, offering speeds of up to 112 megabits per second (Mbps) and enabling HD video and immersive interactive gaming on smartphones, tablets and laptops,” said Markus Borchert, president at NSN for Greater China. “All these TD-LTE benefits will now be available in the 1.9GHz bands, extending the reach of TD-LTE.”
