Chang Xiaobing: China Unicom is firmly on FDD 4G network
On March 22, when attending the 2012 performance announcement, Chang Xiaobing, chairman of China Unicom, said that after the management's research on the 4G license policy, it was decided not to move away from the existing technical route, that is, FDD 4G The internet. Earlier, TD-SCDMA companies released news that all three operators would obtain TD-LTE licenses, making China Unicom and China Telecom nervous. On the previous day when he also attended the results conference in Hong Kong, China Telecom Chairman Wang Xiaochu revealed his true thoughts: China Telecom hopes to obtain FDD LTE licenses, but if the government does not issue FDD LTE licenses in the future, it will be jointly built with China Mobile TD-LTE network or lease China Mobile's TD-LTE network. And this time Chang Xiaobing, chairman of China Unicom, said that the relevant mainland authorities' speeches during the two sessions were integrated. As a result, the market expects that mainland 4G licenses may be issued this year. China Unicom will actively respond. After management's research, it is determined that it will not move away from the existing technical route, that is, the FDD 4G network, and has not received government departments Require telecom operators to use TD network news or pressure in the future. At the same time, he believes that Unicom has no reason to operate both 4DD networks of FDD and TD systems. Will Unicom smoothly evolve through technology and upgrade existing 3G base stations to 4G? Before attending the two sessions, Chang Xiaobing also said that in the evolution of 3G to 4G technology, China Unicom's WCDMA is the most mature. The meaning of this sentence clearly implies that China Unicom is suitable for easy upgrade to FDD LTE, and it is impossible to consume curves Invest heavily to build TD-LTE. From the technical point of view, from the technical point of view, the natural evolution direction of China Unicom's 3G standard WCDMA is FDD LTE. If you upgrade to TD-LTE, you will need to re-examine the technology and spend huge amounts of money to build a network.
