Add WCDMA not open Qualcomm, with the original intention of independent intellectual property rights in recent days, there are news that includes MARVERLL, including several TD-SCDMA (hereinafter referred to as TD) is planning to launch td/wcdma/gsm three-mode mobile phone chip to meet China Mobile TD users overseas roaming 3G business needs. China Mobile Research Institute has shown a high degree of interest in this, Dean Huang in the recently held "TD Intelligent Terminal Technology Development seminar" has said that this will bring the greatest convenience for high-end users. "TD three model, looks very beautiful, but from the plan to the real business is still a long way to go." "There are domestic chip manufacturers to the South are reporters, for TD mobile phone add W C DM a function, means that the need to involve Qualcomm patents and pay fees, will directly increase the cost of TD terminal, but also contrary to the national development of TD's original intention." TD three die hit mobile demand not long ago, a domestic can use C D M a 2000EV do network, go abroad roaming without changing the card can automatically switch to the W CDM A network of H T C mobile phone officially in China Telecom channel shelves. This directly solves the problem of the development of China Telecom's high-end 3G users ——— due to foreign countries such as China, the United States and South Korea, the full range of the use of EV D O country is not particularly much. With the increasing popularity of wireless internet, location, search and other services, 3G data roaming has become a big demand of high-end users. This demand also exists in China's mobile high-end users, and the number of users is even larger. In a conversation with reporters in the South, China Mobile insiders also showed a strong interest in the technology of the 3G dual mode and even multimode. For China Mobile, which is trying to retain high-end users, the demand is more pronounced than China Telecom. In fact, the 3G multimode based on T-D is already included in the next phase plan of China Mobile T D. It is reported that Marvell and other T-D chip companies plan to launch T W CD M g SM Three-mode mobile phone chip. Huang has told the media that if every T-D handset can roam abroad to support W CD M a network application, its roaming cost will be equivalent to the WCDMA cost. Business in the foreseeable future if the real implementation of the three model, T-D mobile phone market competitiveness will achieve a qualitative leap. There is anecdotal speculation that Qualcomm is about to launch the T-D/WC D ma/c D ma/g SM Four-mode chip, so that even if the T-D network is only used in China for a short time, there is still a possibility that the curve will move to the world. But the voice from the chip industry is questioning the T-D three model. "The key to see is so C (System-level chip) or SIP (multi-chip integration) mode, the cost difference is very big." "An unnamed chip business owner told South reporters that the actual development of a single chip is a long way to go, is not a short-term solution to the problem." "It is true that some chip makers are planning to develop tD three model mobile phone chip, China Mobile's interest is also very strong, will certainly give full support, but to tell the truth still stay at the planning level, real business there is no timetable. As for the SIP integration model, it is more flexible at this stage and easier to implement T D three modules. The most direct method is to add t D function to the Qualcomm's existing WC D ma/g S M Dual-mode chip, but this will increase the cost of the T-D terminal which is not too low, and such as compatibility, energy consumption and so on is also the problem to be solved. More importantly, this model still needs to pay the patent cost to Qualcomm, is contrary to the national development T D of the original intention ——— based on independent intellectual property rights. LTE needs more urgent integration of the two models, and the public attitude of China Mobile Research Institute, even if the multimode scheme, single chip is still the trend. According to Huang introduced, the current commercial T-D chip manufacturers, including M Arvell, exhibition, ST-E, core technology and so on. In performance indicators, T D single Chip and W C D M A single chip in the integration of a P, 40nm technology, 3D acceleration, V ideo Hardware codec and so on have been basically the same support capabilities. As a result, if T D three is also pursuing a single chip mode with higher degree of independent intellectual property, it is no doubt. Another factor that affects the development of the T-D three model comes from China Mobile itself. Although the T-D three model can effectively address the needs of China Mobile high-end 3G users, but according to the T-D chip manufacturers, China Mobile is still more energy in the quasi-4G mode LTE. "China Mobile has been urging us to hurry out of the LTE program. "This is the" heart Stone "that is currently moving, said chip makers. Compared to TD three model, also more imminent.
