At the recently concluded Asian Communications Expo, Xi Guohua, chairman of China Mobile, revealed that the TD-LTE industry has matured, especially in terminal chips. Significant progress has been made. TD-LTE mobile phones using 28-nanometer chips have been launched. There are 11 TD-LTE mobile phones on the market. At present, more than 160 TD-LTE terminals have been released worldwide, including 18 smartphones. The global shipments of TD-LTE terminals have exceeded 3 million.
In addition, the integrated development of TD-LTE and FDD-LTE has become an important development direction of global mobile communications, and TD-LTE and FDD-LTE have achieved comprehensive integration of standard industrial products, especially network integration, and many 4G mobile phones have been Can switch between two networks.
It is reported that Lu Yimin, general manager of China Unicom, revealed for the first time that China Unicom is preparing for 4G and is currently conducting FDD-LTE / TD-LTE converged networking trials, but the upgrade from WCDMA to FDD LTE will be very smooth. This may imply that China Unicom will be issued two 4G licenses like China Telecom, but TD-LTE will not build networks on a large scale. In the next 1 to 2 years, it will still be mainly based on existing 3G networks, waiting for FDD to be issued by the competent department -LTE license.
Previously, China Telecom Chairman Wang Xiaochu said that in China Telecom ’s 4G network planning, the FDD-LTE system is still used for the large-scale and wide-coverage 4G network, and the densely populated areas in the urban area will use the TD-LTE system to absorb excess words. In terms of traffic, China Telecom will adopt an integrated solution to meet the needs of all users.
