ZTE said it has successfully conducted an industry-first interoperability verification between FDD-LTE/TD-LTE and GSM/UMTS, which is based on the GSM/UMTS/FDD-LTE/TD-LTE multi-mode Uni-Ran platform.
The successful ZTE test idemonstrates that a cost-reducing step-by-step transition from 2G or 3G to LTE is possible. 2G and 3G networks are well-established and have a substantial amount of subscribers. Currently, when telecommunications operators switch to an LTE network, which provides greater bandwidth and richer services to users, they encounter challenges such as limited coverage.
ZTE said that the test will lead to further convergence between LTE and existing networks and acceleration in deployment of LTE. It also highlighted the capability of these platforms to support HD video.
“The success of the interoperability test showcases how ZTE is at the forefront of creating LTE solutions,” said ZTE Vice President Li Jian. “The company is committed to contributing to global development of the LTE industry.”
Further, the development and application of multi-mode terminals has made it possible for leading LTE operators to use existing 2G/3G networks and provide global roaming to reduce the cost of establishing LTE networks.
