Telecom operators across the globe can now gain quick and simple access to LTEbased mobile broadband for unpaired frequency bands. At the Next Generation Mobile Networks (NGMN) Industry Conference today, Nokia Siemens Networks announced that it has fully integrated TD-LTE with its existing mobile platforms including base stations and core networks. The company also showcased the industry's first concurrent TD-SCDMA and TD-LTE demo. The coexistence of the two technologies is a significant step towards facilitating operators' transition to TD-LTE and was conducted on Nokia Siemens Networks' Flexi Multiradio Base Station.

There is an abundance of available unpaired spectrum in many countries across the world. Operators can use this spectrum to make a quick transition to TD-LTE mobile broadband to meet their immediate connectivity needs or to realize a true mobile broadband experience.

"TD-LTE is an evolutionary path for 3G TD-SCDMA and WiMAX networks, as well as an option for operators around the world who have available unpaired spectrum. The shift from TD-SCDMA and WiMAX to TD-LTE, will be a gradual process, thereby making it important that the two technologies coexist with each other," said Thorsten Robrecht, head of LTE product management, Nokia Siemens Networks. "This achievement marks a solid step towards seamless evolution to TD-LTE and will enable operators to quickly move to the technology."

Nokia Siemens Networks' TD-LTE offering is designed for the global market, targeted to ensure highspeed mobile broadband connectivity across a wide range of enduser devices and applications in networks with unpaired frequency bands.

Based on Nokia Siemens Networks' Single RAN solution that supports LTE in the paired and unpaired spectrum on the same Flexi Multiradio Base Station, the TD-LTE variant is fully compliant with 3GPP Release 8 LTE specifications. In addition, the common platform ensures easy maintenance and rapid evolution to future standards such as LTE-Advanced.

Nokia Siemens Networks supports LTE for both FDD, serving paired frequencies and TDD serving unpaired frequency bands and provides a smooth evolution path to LTE for all operators. With its unique holistic approach to LTE, Nokia Siemens Networks is leveraging its global presence and rich experience in mobile broadband to enable a widespread ecosystem of TD-LTE including interoperability tests, provision of applications, professional services and endtoend delivery. The company has Centers of Competence for LTE in all the leading markets and is actively working with leading device vendors to ensure early commercial availability of TD-LTE infrastructure and devices.
