Two key trends are converging to create an opportunity for TD-LTE and FDD-LTE co-existence. As they deploy their LTE networks, operators are looking for ways to provide enough capacity to meet steep data demand. At the same time, many of them have TDD spectrum available to fill this gap.
At the recent GTI Workshop in Barcelona, Dr. Hua Xu from Nokia Siemens Networks highlighted an innovative and intelligent approach to offloading traffic between TD-LTE and FDD-LTE to increase capacity and optimize the utilization of both FDD-LTE and TD-LTE.
As Dr. Hua explained, it is not enough to simply deploy a TD-LTE network next to an FDD-LTE network to enable traffic offloading. Instead, she described a unique two-prong approach to optimizing the coexistence of TD-LTE and FDD-LTE that both increases capacity and enhances the user experience. Based on a patented algorithm used in base station software, it increases capacity for more users by offloading traffic from overloaded cells to lightly loaded cells.
At the same time, it also improves the customer experience by balancing throughput across these cells. As soon as end users are offloaded to a lightly loaded cell their throughput increases, helping to improve their experience.
Dr. Hua Xu highlighted how our innovation achieves an up to 4-fold increase in the throughput of users who are offloaded between TD-LTE and FDD-LTE and an up to 50% increase in the throughput of users experiencing low throughput.
This innovation is further evidence of Nokia Siemens Networks’ commitment to the globalization and commercialization of TD-LTE. We are also highlighting our TD-LTE innovation at Mobile World Congress 2013 in Barcelona with a demonstration of data traffic offloading between TD-LTE and FDD LTE* using our Single RAN Advanced Flexi Multiradio 10 Base Station and a commercially available dual-mode (FDD and TDD) end-user device. The demonstration and the company’s commercial momentum in TD-LTE will also be highlighted by Rajeev Suri in a keynote address to the Global TD-LTE Initiative (GTI) Summit on February 26, the second day of the Barcelona event.
Network operators, customers, press and analyst are also welcome to view the world’s first TD-LTE offloading and FDD-TDD load balancing demo at the Nokia Siemens Networks’ Solution Experience Center in Hall 3, 3B14, at MWC 2013, Fira Gran Via, in Barcelona, Spain.
