Every year, there is a new generation of technology to bring innovative leaps and breakthroughs to the iPhone. Now a new generation of technology has arrived. Today marks the beginning of a new era for the iPhone. Then Tim Cook went on to say – today, we put 5g into the iPhone. < / P > < p > at the recent Apple launch, Tim Cook prepared such an opening statement for the iPhone 12 series. It’s easy to recall the tone of Steve Jobs’s launch of the first iPhone in 2007 – and the tone of the two is quite similar, giving people the feeling of having to witness a great historical moment. As a result, 5g has become the highlight of the new iPhone in Tim Cook’s script, but is 5g so important? At the same time, the evolution of mobile communication has also made rapid progress in the past nine years. In fact, since Tim Cook became CEO of apple in 2011, iPhone has experienced three generations of mobile communication technology evolution, namely 3G, 4G and 5g. < / P > < p > looking back, the iPhone also experienced the evolution from 2G to 3G under Steve Jobs in 2008. < p > < p > in fact, when the iPhone was born, 3G was already on fire – although its development in the world is uneven, 3G services have been opened in Korea and Japan for many years, and Europe and the United States have also kept pace with 3G (China’s 3G will have to wait until 2009) < / P > < p > nevertheless, the first generation iPhone released in 2007 did not launch 3G, but adopted the mature 2G network, supplemented by Wi Fi function – relying on Wi Fi instead of 2G, the first generation iPhone became what jobs called the “groundbreaking Internet communication device”;. However, soon, jobs introduced 3G into the iPhone and named the second generation product iPhone 3G. < p > < p > on June 10, 2008, at the WWDC hosted by Jobs himself, he spent about 20 minutes at the end of the main forum to introduce the iPhone 3G. The main function introduced was 3G (fast data), which took about 10 minutes. < / P > < p > then compare 3G (21 seconds) with Wi Fi network (17 seconds to open a web page), and then draw the conclusion: the speed of 3G is close to Wi Fi. < / P > < p > open the same email attachment with 2g (edge) network and 3G network, 3G takes 5 seconds and 2G takes 18 seconds, the speed of the former is 3.6 times higher than that of the latter; < / P > < p > after introducing in detail the improvement of webpage and email speed brought by 3G function, jobs introduced the endurance of iPhone 3G (related to 3G) and GPS function combined with 3G network. In addition, jobs also introduced the enterprise support of iPhone 3G and the support for third-party apps. < / P > < p > in fact, compared with the first generation of iPhones, iPhone 3G updates are mainly focused on 3G – and 3G has indeed become the biggest selling point of iPhone 3G in fact. < / P > < p > it is worth mentioning that, with the release of iPhone 3G, Apple has brought iPhone to more markets, eventually covering 70 countries and regions; it has also greatly reduced the price, with the lowest price of $199. < / P > < p > for example, the rapid iteration of iPhone and IOS leads to the transformation of the whole mobile industry; the rapid development of app store promotes the vigorous development of mobile application ecology; the emergence of iPad has triggered the wave of tablet computers With the growth of iPhone sales, Apple’s share price has quadrupled during this period. < / P > < p > of course, the biggest change for apple is that jobs died in 2011 and Tim Cook was CEO. < / P > < p > shortly after becoming CEO, Tim Cook hosted the launch of the iPhone 4S, Apple’s last 3G phone, and the last iPhone with 30 pin interface. Now, this phone is quite a summary of the iPhone in the 3G era. < p > < p > iPhone 5 is actually a mobile phone with many significant updates in many aspects of products. For example, the CPU of A6 chip is twice as much as that of A5 chip, and IOS 6 has more than 200 updates < / P > < p > but what is more noteworthy is that iPhone 5 has created many firsts in the history of iPhone development – the first time it uses 16:9 scale screen, the first time uses lightning interface, the first time uses nano SIM card, and the first time uses unibody technology to build an all metal body And 4G for the first time. < p > < p > after talking about some features, Phil schilier, Apple’s senior vice president, said in his always calm tone that the iPhone 5 added LTE features, with a download speed of up to 100Mbps; then he said that it adopted a single chip, dynamic antenna design, and reached 4G cooperation with multiple operators around the world. < / P > < p > in a word, maybe the major update of iPhone 5 was too bright. The support for 4G network was not particularly eye-catching at that conference, it was just one of many bright features. < / P > < p > for many years, until the iPhone 11 series is released in 2019, 4G network has become the standard configuration of all new iPhone products – in the process of subsequent iPhone new product release, the support for mobile network is no longer mentioned as a product feature. < / P > < p > in fact, as early as the launch of the iPhone 5, the industry has been clamoring about 5g. However, 5g has really entered the public’s attention since MWC in 2017 However, it was not until 2018 that Huawei, Qualcomm, Intel and other manufacturers showed their skills, blowing the concept of 5g into the hearts of the public. < / P > < p > in the MWC in 2019, mainstream mobile phone manufacturers such as Samsung, Huawei and Xiaomi oppo have launched 5g flags, either releasing 5g mobile phones or announcing 5g mobile phone release plans For a while, 5g seems to be on the way to commercial landing on mobile phones, and 2019 is also defined as the first year of 5g. < / P > < p > on April 16, 2019, in a series of rumors and rumors about the introduction of 5g & quot; in 2020 for & quot; iPhone, apple and Qualcomm reached a settlement agreement. On the same day, Intel also officially announced to withdraw from 5g smart phone modem business. This is interpreted by the outside world as apple has no choice in 5g strategy, only choose Qualcomm. < / P > < p > in July 2019, Apple announced the acquisition of the majority of Intel’s smartphone modem business at a price of US $1 billion – thus, apple embarked on the road of self-developed 5g. < / P > < p > in the next year or more, with the commercial landing of 5g, mobile phone manufacturers in Android camp have launched 5g mobile phones. Huawei, Samsung, Xiaomi, oppo, vivo and other manufacturers all follow up quickly, and even directly lower the price of 5g to less than 2000 yuan in 2019 By 2020, in addition to a small number of entry-level models, 5g function has become the standard configuration of many Android manufacturers’ mobile phones. < / P > < p > according to data, by the time the iPhone 12 series was released, mobile phone manufacturers had released 112 5g phones. < / P > < p > however, as the 113th 5g phone, the role of 5g in the launch of the iPhone 12 series became extremely strange. On the one hand, it is a revolutionary leap in Tim Cook’s mouth; On the other hand, it has become an empty term in the product introduction section of Apple’s launch conference – everyone is talking about 5g is very good, and the speed can reach 4gbps, but no one has said clearly what tangible functions 5g can achieve on the iPhone 12 series. < p > < p > but in fact, compared with the actual experience of 3G / 4G, 5g is more like a bright label for consumers, telling everyone: 5g iPhone is coming, you can buy it. Protect the environment make complaints about

, of course, but you can imagine that, even though it is more expensive, apple and 5G are ready to cut the iPhone 12 series, though some people may have tucking away the headset and earphone (known as protecting the environment). < / P > < p > WOW! What a wonderful day. We have been looking forward to this day. From the beginning of the iPhone and today’s achievements, it’s unbelievable to think about it. < / P > < p > that’s true. From 2007 to today, from 2G, 3G to 4G, and then to 5g era, iPhone has gone through 14 iterations, and its operating software has become IOS 14. Among them, A-Series chips have also changed from A4 to today’s A14 bionic. It carries one of the largest mobile application ecosystems in the world, and its sales volume exceeds 1 billion Next, Tim Cook praised the iPhone 12 series, including 5g network, A14 chip, hyper retinal screen, MagSafe, camera, lidar scanner, iPhone’s largest screen to date, and then said: < / P > < p > thus, in Tim Cook’s discourse, the new era of iPhone points to 5g, even though it is related to 3G and 4G Compared with the experience improvement brought about by 5g, the iPhone 12 series has not been able to present incomparable advantages directly. < / P > < p > maybe, the 5g era has indeed arrived, and the iPhone 12 series is indeed one of the best smartphones in the 5g era; there is no problem in buying and buying, but before you buy, think about a really key problem: < A= https://ibmwl.com/chinese-version-of-k-car-reading-a10e-design-drawing-exposure/ target=_ blank>Chinese version of K-car: reading a10e design drawing exposure
