Hello, dear.
With the increasing maturity of 5G technology, our mobile communication network has also begun to evolve from 4G to 5G. Huawei has its own views on the direction of evolution.
Large-scale 4T4R Deployment: Foundation for 5G
The rapid growth of MBB services such as mobile video has generated an exponential surge in data traffic, creating capacity and user experience challenges for various operators. Operators must discover greater spectral efficiency, and multiple-antenna technology is an effective solution to help tackle these concerns. Network-wide extensive 4T4R deployment can greatly boost cell capacity and enhance cell coverage. Cell edge users in particular will be able to enjoy better voice and video services. These improvements in coverage and user experience will become more pronounced with the enabling of software features like TTI Bundling(TTIB) and Turbo Receiver.
4T4R can offer a substantially enhanced user experience. As the terminal is upgraded from 2R to 4R, the single-user downlink peak rate can be increased to 1.8 times, while that in the uplink will increase to 1.4 times. With the deployment of 5G, shifting from an LTE 4R handset to a 5G NR device will produce a further 1.51 times and 1.23 times improvements in single-user downlink and uplink peak rates respectively.
The idea of deploying 4T4R as the foundation for 5G has been widely accepted throughout the industry. In terms of terminals, major manufacturers including Huawei, Samsung, and Sony have rolled out a total of over 20 models of 4R terminals. This indicates the arrival of a new stage of smart terminal development marked by Gbps-level data rates. As 4R terminal's penetration rate rises, the gains of 4T4R will also continue to increase. As for networks, more than 60 operators worldwide now boast large-scale commercial 4T4R deployment and this figure is expected to exceed 100 by the end of 2017.
Thank you for browsing, and hope that 5G applications can be used by us as soon as possible.
