At the 2016 Global MBBF (Mobile Broadband Forum), Huawei demonstrated a 5G and LTE Dual Connectivity live demo with a 4K video on-demand service. The demo was based on Cloud RAN architecture with a 21Gbps single user peak throughput achieved.
Huawei said this Cloud RAN-based 5G and LTE Dual Connectivity makes possible the fast deployment of 5G NR (“new radio”) over existing LTE networks, and serves as a milestone for efforts towards an initial 5G launch.
With the development of Augmented and Virtual Reality systems, HD video, WTTx broadband access and Cloud-based services, the company commented that 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 continues to evolve 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 Cloud RAN architecture achieving efficient regional coordination and resource allocation among multiple systems, frequency bands, sites and diversified service requirements, Huawei believes that 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.
Dr. Yuefeng Zhou, CMO of Huawei Wireless Network Product Line, commented, “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.”
