At the 2016 Global MBBF (Mobile Broadband Forum), Huawei displayed a 5G and LTE Dual Connectivity live demo with a 4K video on-demand service. The demo is based on CloudRAN architecture with a 21Gbps single user peak throughput achieved.
The success of Huawei’s CloudRAN based 5G and LTE Dual Connectivity makes the fast deployment of 5G NR (New Radio) over existing LTE networks possible, and serves as a milestone for efforts towards an initial 5G launch.
With the development of AR/VR, HD video, WTTx broadband access and cloud-based services, 5G NR needs to be deployed first in central hotspots to deliver the extreme experience of ultra-high capacity and ultra-low latency. Meanwhile, the existing LTE network keeps evolving with the introduction of new technologies such as 3D Massive MIMO, to protect network investment and improve network capacity, spectrum efficiency and coverage in urban areas.
With the CloudRANTM architecture realizing efficient regional coordination and resource allocation among multiple systems, frequency bands, sites and diversified service requirements, the Dual Connectivity solution will utilize the complementary benefits of 5G and LTE, and pave the way for the initial launch of 5G NR with reduced roundabout transmission delay and handovers, robust link reliability and improved end user experience at cell edges.
Dr. Yuefeng Zhou, CMO of Huawei Wireless Network Product Line, said: “It is of vital importance to guarantee end users with a ubiquitous high data rate experience in densely populated urban city areas with high buildings and complex roadways. Recently, 3GPP standardization has made significant progress in 5G and LTE Dual Connectivity. We expect to strengthen our cooperation with industry partners on 5G innovations based on these real application scenarios.”
