Qualcomm believes that 3G will exist for a long time in the future, but in the Chinese market, 3G has gradually withdrawn from the market, and China Telecom and China Mobile should be the fastest operators to abandon 3G networks.
The two major operators in China currently operate 2G\3G\4G networks at the same time, but their respective systems are different. China Mobile is a GSM/TD-SCDMA/TD-LTE system, China Telecom is a CDMA/CDMA2000/TD-LTE/LTE-FDD system, and China Unicom is a GSM/WCDMA/TD-LTE/LTE-FDD.
Due to the particularity of CDMA, it is estimated that China Telecom will be the fastest operator to abandon 2G and 3G at the same time. China Telecom's current CDMA/CDMA2000 adopts the 800MHz frequency band. This is a high-quality low-frequency spectrum. After obtaining the permission of the Ministry of Industry and Information Technology, it is using this frequency band to build a LTE-FDD-covered vast rural area. Recently, it released a message indicating that the frequency band will be accelerated in the year. Build LTE-FDD.
After LTE-FDD covers the whole country, China Telecom should rapidly promote the commercialization of VOLTE technology without having to rely on CDMA networks to provide voice call services. When will CDMA/CDMA2000 be retired from the country.
China Mobile has made TD-SCDMA achieve its goal of three-point world in the 3G era. However, its coverage of TD-LTE network is more than that of TD-SCDMA and GSM. - LTE network, and voice mainly depends on GSM, so TD-SCMDA should be the fastest, but most of its low-end users are still using GSM network, even if China Mobile actively promotes VOLTE technology based on TD-LTE network The commercial use is also difficult to allow users using the GSM network to completely retire, which will be a fairly long-term process.
The situation of China Unicom is more complicated. Under the impetus of the previous leadership, I hoped to take into account the development of 3G and 4G at the same time. Therefore, the construction of 3G network has led to a huge scale of the network, and its debt is high, which will bring the current leadership hope to rapidly promote the construction of 4G network. The problem is that it is estimated that its 3G network is longer than China Mobile and China Telecom. As for 2G networks, it is similar to China Mobile. A large number of users will still use 2G networks for quite a long time.
Therefore, CDMA/CDMA2000 will be the fastest exit market. Qualcomm expects that there will be no longer a long-term hope for 3G. In particular, China Telecom and the industry chain hope to get rid of the expensive “Qualcomm taxâ€, which will lead to the rapid exit of this technology. .
