Be challenged Nvidia and other chip manufacturers have displayed multi-core processors designed for tablets and smartphones at the Las Vegas International Consumer Electronics Show (hereinafter referred to as "CES"), but some industry insiders and analysts are concerned about whether mobile devices The multi-core processor really needs to be questioned. Analysts pointed out that according to the design, several of the latest mobile operating systems do not support dual-core processors, such as Windows Phone 7.5 "mango", and most smartphone and tablet applications do not require dual-core or quad-core processing power at all, nor can they Benefit from it-except for some videos and games. In view of this, Microsoft and its partner Nokia do not actually think of the advantages of dual-core Android smartphones produced by Samsung and HTC. To emphasize this, Microsoft also held a challenge at CES. Windows Phone Evangelist Ben Randolph bet that his Windows Phone HTC TItan was running apps, online search and other events. The speed will exceed any other smartphone, and the winner will receive a $ 100 reward. Randolph said he only lost once in a contest with about 20 challengers, and the winner was an iPhone 4S user, Randolph paid him cash on the spot. Randolph and Greg Sullivan, senior product director of Windows Phone, pointed out that the focus of Windows Phone is how to provide users with the best experience, not processing speed. In fact, the promotional slogan for Windows Phone 7.5 is "Put People First". Sullivan said in an interview: "Dual core is less important to mobile phones, and most smartphone users are not clear about its functions. Is there any software that will make full use of this processing power? This is a problem." Sullivan said Just as more and more tablets will be upgraded to quad-core processors, Windows Phone and other mobile operating systems are bound to transition to dual-core processors in the next few years. Future trends Many bloggers and commentators, including JR Raphael, a contributor to the US IT website Computerworld, said that the Asus Transformer Prime tablet experience will indeed be greatly improved by the quad-core processor, because at the same time When running multiple applications, quad-core processors will provide better performance. Asus released the Transformer Prime tablet in November last year. But Sullivan also pointed out that dual-core and quad-core processors have so far been mainly attractive to technology industry insiders and mobile device enthusiasts: "This is like the mentality of fans who want to have two cam engines. I think that in On the issue of smartphones, users simply cannot tell what dual-core is. " Kevin Burden, an analyst at market research agency ABI, pointed out that on the other hand, some tablets that value dual-core value, such as the BlackBerry PlayBook, can indeed easily handle various applications and data downloads. Boden said: "The tablet's quad-core processing capacity is not important now, but the question is where is this technology going?" Once smartphones and tablets use faster processors, the biggest obstacle is their extremely high energy consumption. For example, ASUS just released a 7-inch tablet priced at $ 249, which is produced by Nvidia. The quad-core Tegra 3 processor is equipped with Android 4.0 "Ice Cream Sandwich" operating system. Boden said: "The pursuit of faster processor speeds will greatly reduce other performance of mobile devices, such as battery life." Make the most of Jack Gold, an analyst at market research agency J. Gold Associates, said that most applications today do not require smartphones with dual-core processing capabilities or tablet computers with quad-core processing capabilities. But he predicts that in the coming year, the developer community will develop a number of applications that can take advantage of faster processing speeds. Mobile operator Sprint is launching multiple smartphone and tablet products equipped with multi-core processors, but the company should realize that the speed of wireless networks supporting such devices must also be increased. Sprint announced that two smartphones such as Galaxy Nexus and LG Viper will run on its upcoming 4G LTE network, both of which are equipped with dual-core processors. Ryan Sullivan, director of product development at Sprint, said: "We are always pursuing the fastest technology, but this may be more important for mobile industry participants than consumers, because we all want to Take the lead in the competition. " According to Sullivan, when Sprint first deployed its WiMax network as a 4G technology, it realized that it is not enough to simply introduce users to how fast a 4G network is: "We must tell them what they can do with 4G technology to make them truly Feel the benefits of this technology. So, you ca n’t just talk about speed or how fast the processor is, but let them understand which applications you can use. †Operators participate in the war, two standard games Standards disputes have always existed. Behind the competition for different standards is the game of interest groups. UnionPay and telecom operators all hope to compete for their dominance in the mobile payment industry through their own standards. Xie Yuqi, Director of the Policy and Standards Division of the Communications Development Department of the Ministry of Industry and Information Technology, once said that the coexistence of multiple standards poses obstacles to the large-scale application of mobile payments. The 13.56MH z payment scheme favored by UnionPay is an international mobile payment standard. The patents are controlled by international giants such as Nokia and Sony. They are widely used in the world and have mature development. They are widely used in contactless card fields such as transportation, finance, social security, and fueling. Applicable to most existing POS terminals; however, its shortcomings are obvious. First, users must use mobile phone payment services to replace the mobile phone and SIM card specially made by the operator; secondly, the signal is easily affected by the metal structure to ensure the strength of the signal. The back cover of the phone cannot use metal; again, it does not support remote recharge. As for the 2.4GHz mobile phone payment solution favored by China Mobile, users only need to replace a specially made payment SIM card with radio frequency to realize payment. Even if the mobile phone is replaced, this card can still continue to have the mobile phone payment function. However, as a domestically-independent R & D product and China Mobile ’s first product, its industrial chain is not yet mature. Due to the inconsistency of its working frequency with the POS of major industries such as banks and public transportation, the terminal needs to be re-laid or modified, which requires public Coordination with the financial sector and telecommunications operators requires a certain amount of work and relatively large costs. According to estimates by Everbright Securities, at the end of 2010, there were a total of about 3.33 million POS machines nationwide. Assuming a POS machine costs 2,000 yuan (less than the market price), a total investment of 6.66 billion yuan will be required.
