China Mobile since 13 years in December since the official commercial 4G, in just two years time, has built more than 1 million 4G base stations, the development of more than 280 million 4G users, covering more than 300 city, with the fastest speed to build the world's largest commercial network 4G. However, due to the full maturity of the 4G market, 4G+ came, 5G has increasingly become the focus.
Beginning in June this year, China Mobile accelerate the 4G+ to carrier aggregation based comprehensive industrial maturity and pilot applications, has been in a number of urban commercial. The definition of China Mobile 4G+, double carrier aggregation technology is not limited to existing, it also includes three or five above the carrier carrier carrier aggregation, TDD-FDD, 3D-MIMO, MDT, joint transmission 256QAM, TDD dynamic time slot allocation and many other enhancement techniques. 4G+ technology will be used to enter the Gbps era, the frequency spectrum utilization increased 3~5 times, the operator's single station operation and maintenance efficiency significantly increased, while the vertical industry applications to achieve penetration.
In accelerating the business process 4G+ at the same time, China Mobile is also actively preparing for the development of 5G. As early as 2011, China Mobile began to study the key technology of 5G, the 5G vision, 5G key indicators and 5G requirements of the development of the white paper, writing made outstanding contributions.
The next step, China Mobile will actively promote the 5G related research, around the market, technology, spectrum, standards and other aspects of the relevant work. In order to promote the end-to-end 5G mature industry chain, and enable 5G to better serve the Internet and vertical industry, China Mobile is creating a 5G joint innovation center, the joint communications companies, Internet companies, vertical industry partners, on the one hand, the key technology to carry out verification, system testing and experiment, promoting technology and other products mature. On the one hand, from the perspective of the development of the market and let 5G 5G innovative applications, technologies and standards, product development to meet the emerging 5G market and business needs, thereby creating a win-win 5G ecology, actively meet the new development brought by 5G.
