China Mobile apple cooperation problem: iPhone needs to integrate seven systems

since Xi Guohua, chairman of China Mobile (Weibo), pointed out a few days ago that the introduction of iPhone depends on Qualcomm (Weibo) chip technology, industry analysis shows that if China Mobile wants to introduce the next generation iPhone, this model, which is predicted to achieve a 35% weight reduction of the whole vehicle compared with 2015, will need to integrate seven communication systems from 2G, 3G to 4G, Qualcomm, the chipmaker of iPhone 5, is particularly bad at TD-SCDMA

China Mobile will not deliberately introduce iPhone for 2G

as for when China Mobile will introduce iPhone, Xi Guohua, chairman of China Mobile, recently admitted that the biggest constraint now is not business, but technology, which is related to TD-LTE and TD-SCDMA chips. Apple pursues first-class products rather than Qualcomm's chips from 2011 to 2018. In this way, the timetable for China Mobile to introduce iPhone is not decided by China Mobile and apple, but by Qualcomm

moreover, Xi Guohua clearly pointed out that China Mobile did not introduce iPhone for use on 2G. He said that the effect of Apple iPhone on 2G is not good, which is the truth, so I am not interested. He also stressed that China Mobile is more interested in using td-lt to fund the core technology research and industrialization project construction of the new material industry, and iPhone will be used in TD-LTE network

however, according to Apple's consistent practice, it will not develop iPhone for one system alone, but integrate multiple systems in iPhone; Moreover, each standard is downward compatible, that is, the iPhone of 3G standard is compatible with 2G; The 4G iPhone is compatible with 3G and 2G. Therefore, the industry predicts that in order to meet the standards that China Mobile can use, this iPhone will be very complex and integrate GSM, WCDMA, fdd-lte, CDMA, CDMA2000, TD-SCDMA, TD-LTE at the same time

Qualcomm lacks TD-SCDMA chip technology foundation

even for Qualcomm, the world's best chip manufacturer, it is by no means easy to introduce such chips, which may be the reason why China Mobile and apple have been unable to announce cooperation

a small part of Qualcomm, which costs only fluoropolymer, glass and other expensive materials, released a new LTE chip in mid June. It is said that this chip is very suitable for iPhone, but it does not integrate TD-SCDMA that China Mobile wants

Qualcomm does have the ability to integrate multiple communication systems into one chip, which is convenient for manufacturers to manufacture multi-mode terminals. At present, the iPhone 4S widely sold around the world also uses Qualcomm chips, which are compatible with GSM, WCDMA, CDMA and CDMA2000. However, Qualcomm has never made TD-SCDMA chips in history, and lacks the technical foundation. Therefore, the industry believes that the integration of TD-LTE chips into Qualcomm's chips is not a problem for Qualcomm, However, it is difficult to integrate TD-SCDMA system

however, as early as last year, the industry said that Qualcomm intended to enter the field of TD-SCDMA chips, but so far it has not seen Qualcomm launch any TD-SCDMA chips. Therefore, it is expected that Qualcomm's research and development of TD-SCDMA is only to be able to have TD-SCDMA compatible technical capabilities in other chips
