Huawei releases 4.5G plan

Huawei on October 15, 2014 released its plan to evolve 4G network technology to what it considers 4.5G vision at the GSMA Mobile 360 Series. Expected to be launched in 2016, Huawei’s plans for 4.5G will lead mobile communications into the Gigabit era for the first time, and will spearhead the next phase of the revolution for the communications industry to enable people to enjoy an increasingly intelligent lives. Huawei’s 4.5G technology will aim to provide users with ultra-high definition, 3D and possibly holographic videos. It opens the era of Internet of everything as well as service-oriented network architecture prior to 5G being commercialized.
Mr. Ying Weimin, President of Huawei Wireless Network Research and Development, said, “4G enables users to freely connect with each other, enjoy superior mobile broadband experiences and download at high-speeds, anytime, anywhere. Over the next couple of years 4.5G technology will be deployed that will offer faster speeds, lower latency and better functionality than the best 4G technologies currently available. It will also open up new revenue streams for operators resulting in a healthier and more profitable mobile broadband business”
Expected to be commercialized in 2016, Huawei’s 4.5G research starts by looking at the ongoing 3G Partnership Project (3GPP) releases for LTE and LTE-Advanced. 4.5G standardization forms a part of this and is expected to be completed in 3GPP releases 13/14.
Key features of 4.5G technology include the ability to have lower latency at 10ms, a peak download rate of around 6 Gbps and the support of 100,000 connections within a one kilometer square. These present new challenges for network designs which need to support new techniques for air interface, spectrum frequency and architecture. These include higher order multiple-input and multiple-output (MIMO), massive Carrier Aggregation (CA), Semi Orthogonal Multiple Access (SOMA), shorter wireless scheduling time, the use of unlicensed spectrum, open and agile network cloud architecture to facilitate quick new services deployment.
