ZTE successfully completed the LTE interoperability and convergence test, FDD/ TDD LTE PS handover test to provide the foundation for seamless communications between different LTE modes. The test showed that when the FDD/TDD LTE dual-mode device is connected to the LTE network and large files are downloaded, the success rate of the FDD/TDD LTE bi-directional handover can be up to 100%. Moreover, the quality of the user experience was not affected.
The infrastructure used to carry out the test consists of commercial system equipment provided by ZTE and an FDD/TDD LTE dual-mode USB card, provided by Hong Kong Applied Science and Technology Research Institute Company (ASTRI).
This experiment was designed to improve user experience in an FDD/TDD LTE handover scenario. It is a part of ZTE's strategy to push LTE interoperability and convergence. ZTE completed the world's first TDD-LTE and FDD-LTE/UMTS/GSM interoperability test. ZTE also launched the first TDD- LTE/FDD-LTE/UMTS/GSM multi-mode data card and the TD-LTE/TD-SCDMA/GSM dual-standby smart phone prototype. Last year, the first TDD-LTE/FDD-LTE dual-mode network was unveiled in Sweden by ZTE and Hi3G.
"The supported functions and improved performance provide opportunities for operators to speed up the development of the LTE industry," said Wang Shouchen, Vice President, ZTE.
