BANGALORE, India -- Qualcomm and Ericsson have demonstrated LTE Time Division Duplex (TDD) mobility in India, including the ability to hand off calls between basestations.
Wireless Broadband Business Services, one of Qualcomm’s India LTE partners, and Ericsson said they achieved LTE TDD outdoor mobility at 2.3 GHz Tuesday (Nov. 30) in northwestern India. The demo is part of Qualcomm’s strategy to accelerate the deployment of LTE in concert with 3G to drive the growth of mobile broadband in India.
The demonstration streamed multiple, live HD video feeds to a mobile van, showing the ability to hand off between basestations while maintaining session continuity. The partners used Ericsson’s Radio Access Network and Evolved Packet Core technologies and USB dongles based on Qualcomm’s MDM9x00 multimode chip set that supports both LTE and 3G.
Nokia Siemens Networks earlier this month demonstrated its TDD version of LTE. The demonstration used 4G mobile technology running on commercial hardware in the 2.3-GHz frequency band across 20 MHz of bandwidth.
The Qualcomm-Ericsson demonstration advances Qualcomm’s India strategy to accelerate infrastructure readiness and deployment of LTE TDD, eventually working towards 3G-LTE interoperability trials next year and the commercial availability of LTE TDD infrastructure, chip sets and devices.
Qualcomm said it expects to attract other 3G HSPA or EV-DO operators to its LTE network in order to comply with Indian government deployment requirements for the wireless spectrum. Once those requirements are met, it will exit the Indian joint venture.
