SK Telecom has announced two-way handover that supports both FDD LTE and TDD LTE in one device. Operator, together with Ericsson and Altair Semiconductor, demonstrated handover in between two different duplex modes of the LTE technology standard in a moving vehicle environment. SK Telecom showcased the technology at an operating committee meeting held by the Next Generation Mobile Networks (NGMN)  from September 18 to 20 in Turin, Italy.

For development of the LTE FDD/TDD handover technology, SK Telecom, Ericsson and Altair Semiconductor created a test field around SK Telecom’s Bundang Building with a cell radius of 500m-1.5km and in a moving vehicle environment. SK Telecom said that the handover technology demonstration verified that the performance of handover between FDD LTE and TD-LTE is the same as handover on single FDD mode.

The demonstration also showed that the technology is capable of adjusting the coverage of LTE FDD and LTE TDD base stations as well as offloading traffic depending on the level of concentration in areas covered by both duplex modes.

SK Telecom also introduced its other core LTE technologies such as Multi Carrier  and HD Voice  (VoLTE) at the NGMN meeting.
