Nokia Siemens Networks is to demonstrate data traffic offloading between TD-LTE and FDD-LTE using the company’s Single RAN Advanced Flexi Multiradio 10 Base Station and a commercially available dual-mode (FDD and TDD) end-user device at MWC this year.
The capability to offload traffic between TD-LTE and FDD-LTE networks paves the way for operators to optimize the use of both FDD-LTE and TD-LTE services.
‘Many operators with FDD-LTE networks also own spectrum suitable for TD-LTE services,’ said Tero Peltola, head of the LTE business line, NSN. ‘With offloading capability, the two LTE modes can work hand in glove. As multimode devices supporting both FDD and TD-LTE become more common, operators will be able to take full advantage of their spectrum allocations and deploy TD-LTE as an integral part of their overall mobile broadband service.’
In a recent TD-LTE offloading and FDD-TDD load balancing test conducted in Arlington Heights, Illinois, USA, Nokia Siemens Networks demonstrated a four-fold increase in the throughput for subscribers offloaded from a heavily loaded FDD-LTE network to a lightly loaded TD-LTE network.
The test achieved up to 50% increase in throughput for users at the edge of the coverage area. In addition, it showed that load balancing of heterogeneous networks at the same frequency increased throughput for users at the edge of the coverage area by up to 180%.
Network operators, customers, press and analysts can view the TD-LTE offloading and FDD-TDD load balancing demo at the Nokia Siemens Networks’ Solution Experience Center in Hall 3, 3B14, at MWC 2013, in Barcelona.
