Huawei said it displayed a 5G and LTE Dual Connectivity live demo with a 4K video on-demand service at the 2016 Global MBBF (Mobile Broadband Forum) in Tokyo. 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.
According to Huawei, 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 CloudRAN 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, said the company.
