5G key technologies and business forecast

Abstract

On June 14，2018，the 3GPP plenary meeting(TSG#80) approved the freeze of the independent networking function of the fifth generation mobile communication technology standard(5G NR). Coupled with the NR standard which was completed in December 2017, 5G has completed the first phase of full function standardization, and has entered a new stage of industrial sprint. The SA function freeze not only enables the 5G NR to have the ability to deploy independently, but also brings a new end to end new architecture, enabling the intelligent development of enterprise customers and vertical industries, bringing new business models for operators and industrial partners, and opening a new era of full connection. This paper firstly introduces 5G network key technologies, such as large-scale antenna, service-oriented architecture, edge calculation and network slicing, and analyzes the process and development status of 5G commercial application on the basis of elaborating the future business model applied in the three scenarios.
