Shulou(Shulou.com)06/03 Report--

The hit movie "the climber" during the National Day holiday makes people know the tragic story of the Chinese mountaineering team's first climb of Mount Everest. It is through the sincere blood of these stories and the belief in family and country that the meaning of the saying "to climb the peak is to conquer the peak" is particularly profound, surpassing the footprints left by thousands of people, and then reaching places that no one has ever reached before.

In any field, "climbing the peak" and "exploring" seem to be the innate instincts of human beings. Perhaps it is precisely because of the existence of this instinct that our species is not only satisfied with survival, but also continue to explore in art, sports, science and technology after adequate food and clothing, and constantly paint new colors for civilization.

Even behind the seemingly mundane product of our most familiar mobile phone, there are also countless climbers'"Everest stories" written by climbers. Li Xiaolong, president of Huawei's first mobile phone product line, told pollen and the audience the "climber story" behind Huawei's Mate30 series at the Huawei School Cafe Show at Huawei's Intelligent Life Pavilion (Shanghai Aegean Sea) on Oct. 13.

Mobile phone R & D: fifty years of climbing the Peak

If we regard the civil mobile phone invented by Martin Cooper, a Motorola engineer, in 1973 as the first generation mobile phone, we can clearly see the law of the evolution of this product. From the mobile phone, which was bulkier than the fixed line at that time, to the smartphone, which is now so thin that it can be folded or even curled, the law of the evolution of this product probably has two directions: one is "climbing the peak". In the existing technological trends, continue to move forward, conquer the higher peak; the other is to "seek", constantly expand the tentacles of technology, spying on innovation.

It is believed that the evolution curve of the former is obvious to everyone, from the brick-sized mobile phone to Nokia, which can smash walnuts, to today's 200-300g mobile phones, behind the sensory changes is the continuous improvement of chip technology, material technology and so on. Including a large number of convenient photography functions, Panasonic just broke through autofocus on mobile phones in 2004, and today Huawei Mate30 series has put forward the concept of "movie camera". This includes breakthroughs in numerous areas of detail, such as photosensitive elements, photography algorithms, color adjustment, and so on.

As for the latter, the mobile phone has grown from a "brick" that can only make phone calls to a necessary tool that is firmly bound to countless scenes in life today. Many of the functions we take for granted today come from innovations that might seem unnecessary a few years ago or more than a decade ago. For example, in 2000, when the storage capacity of the phone was usually only 20 to 30 megabytes, Samsung launched a phone with MP3, and in 2011, Google launched Mobile wallet service (mobile wallet service) in conjunction with Visa, which has linked offline payments to the phone. Now in these fields, the first person to discover virgin land may have been surpassed by newcomers, or even no longer reclaimed at all, but the significance of innovation is still irreplaceable.

In the nearly 50 years of the development of mobile phones, climbers have been thinking about these two questions. Can this function be better? Can this product be of any other use?

Listen to the dangerous peak scenery of the Mate30 series at Huawei School.

Even today, when mobile phones are infinitely close to omnipotence, climbers are still on the road of climbing and searching. Bruce Lee uses three "generations" to describe Huawei's Mate30 series products-commercial generation, R & D generation and exploration generation.

On this phone, we can clearly see how Huawei has climbed up and surpassed the footprints it once left.

After the launch of Huawei Mate20 X (5G), which is known as the "first generation 5G mobile phone", the 5G version of Huawei Mate30 series has achieved great strides compared with the previous generation. Based on Huawei's accumulation in the field of vertical and horizontal communications, the Mate30 series 5G version firmly chose the 5G dual-mode networking mode that supports SA/NSA. SA (independent networking mode) can bring lower latency and can be better used in industrial interconnection, autopilot, medical and other scenarios. Bruce Lee mentioned that although China's three major operators insist on choosing the SA network route, many overseas operators only choose the NSA network with base stations under the 4G core network from the perspective of investment and return. Huawei Mate30 series 5G version supports 5G dual mode, which can not only meet the 5G needs of users at home and abroad, but also cope with the change of networking mode in the long run.

In addition to supporting 5G dual-module network functions, this "second-generation 5G mobile phone" also carries the first flagship 5G SoC and has a sophisticated antenna design to ensure efficient and stable and smooth connection to the network, while reducing cross-chip signal transmission consumption through chip integration and further reducing power consumption. Compared with the previous generation of products, Huawei Mate30 series 5G version begins to consider more practical application problems, such as how to ensure the user experience through the seamless switching between 5G and 4G networks in the process of gradual coverage of 5G signals, rather than just considering whether the 5G network can be connected successfully.

For example, in the field of fast charging, which has always been good at, Huawei is still making breakthroughs through continuous research and development. In addition to increasing the wired and wireless fast charging power to 40W and 27W respectively, Huawei has also begun to explore breakthroughs in charging scenarios, opening up wired fast charging and wireless car charging in automotive scenarios. Bruce Lee specifically mentioned that in the way of calculating the charging power, in fact, the input power of Huawei wireless charging is 36W, and the effective power of the last step of charging is 27W, which is very close to wired charging. But Huawei still chooses a more appropriate way of counting, rather than using the so-called "36W wireless fast charge" to attract the attention of consumers.

Of course, we can also see how Huawei Mate30 series is seeking uninhabited land.

Take the concept of "four movies", for example, there are many new breakthroughs in mobile photography. At the Huawei School event site, Bruce Lee focused on the function of time-delay photography. In the past, the solution of most manufacturers was to extract the entire video stream and then extract the images of individual frames to simulate the function of time-delay photography. Huawei pioneered a scheme to use super-sensitive cameras to shoot and synthesize video streams in a single frame.

In contrast, the delay video captured by the mobile phone with this scheme is clearer, and the strong photosensitive ability of the mobile phone hardware can also support dark shooting when the light is weak. Therefore, Huawei Mate30 Pro took the lead in realizing 4K ultra-wide-angle dark state delay photography. Whether it is the process of blooming epiphyllum or the flow of stars, these images, which originally needed professional equipment to capture, now only need ordinary people to press the mobile phone shutter. In addition, the audience was even more surprised when they saw Mate30 Pro in PPT capture the moment of balloon burst in an instant and slow down through ultra-high-speed photography.

In fact, the climbing stories of mobile phone manufacturers are highly similar to the trajectory of human exploration of the world. In the era of great navigation, people gradually come out of the state of ignorance, and every piece of land explored is polished unknown. Just like the mobile phone research and development in 2000, music, text messages, games, storage. The arrangement and combination of each function and mobile phone is full of freshness. Today, the function of mobile phones is as extensive as human footsteps all over the world, and climbers can only move forward for nine days and five oceans.

That's why Huawei wants to climb Mount Everest. As the first sequence of mobile phone manufacturers, Huawei told the world that there is still boundless scenery above the dangerous peak.

Reinventing the Peak: Bruce Lee tells the story of the climber behind Mate30

Today, when we talk about the era of great navigation or the first climb of Mount Everest, the long journey has long been transformed into a few descriptions or even a symbol. Similarly, the sweat behind scientific and technological innovation is so heavy that the word "scientific and technological innovation" almost seems powerless.

As many people imagine, the process of mobile phone research and development takes place in a high-end laboratory. But this time at Huawei School, Bruce Lee told a lot of special scenes that were not easy to think of. Bruce Lee told you that in the process of capturing Mount Qomolangma, a lot of the climbers' work was done on high-speed trains, roofs and even Tiananmen towers. In order to ensure the commercial 5G experience of Huawei Mate30 series, Huawei has carried out the most extensive and complex 5G tests, including more than 20 overseas countries, more than 30 cities in China and more than 50, 000 test cases. The live broadcast of the "October 1st" military parade uses Huawei's 5G CPE, and Huawei has specially set up a "security team" to ensure that the live broadcast of the military parade is foolproof. In order to ensure smooth communication on the high-speed railway, Huawei staff conducted field tests on trains such as China Fuxing, Japan's Shinkansen, and Germany's ICE. They took more than 800 trains and covered more than 400,000 kilometers, with tickets piled up to more than one person's height.

At the same time, in the process of capturing Mount Qomolangma, climbers do not always delve into sophisticated topics such as 5G and time-lapse photography. Very often, a small function is worth setting up a special team to deal with. Take the function of grabbing red packets, for example, in order to improve the user experience, Huawei even specially set up a "red packet grabbing working group" to carry out hundreds of thousands of tests by constantly clicking on the screen with a robotic arm to realize the identification of red packet grabbing data packets, and immediately increase the frequency of the phone and give priority to transmitting data packets. It not only helps users grab red packets faster, but also does not keep mobile phones in a state of high energy consumption for a long time by turning on the so-called "red packet grabbing mode".

For example, in order to test the anti-freezing ability of Huawei Mate series, engineers took their products through the polar regions and Mount Qomolangma. Also used to crouched on the hillside in the field in the middle of the night wearing a military coat, just to better adjust the algorithm parameters of the Mate30 series shooting the Milky way.

At the Huawei school show, Bruce Lee told the audience about the R & D cost of Huawei's Mate30 series: $300m, 3000 people, 36 months. These money, manpower and time investment, formed a climbing team, through the cold, through the Milky way and epiphyllum blossoms.

From these R & D stories, apart from the starlight of innovation and the sweat of climbers, we can read Huawei's answer to the "ultimate question" of the mobile phone industry. In the 1980s, the group of climbers represented by Motorola asked themselves, can this function be better? Can this product be of any other use? After constantly getting affirmative answers, the climbers continued to climb for nearly fifty years. Today, Huawei, which is almost at its peak, has once again answered these two questions: the existing functions of mobile phones can be better, and mobile phones can be used for other purposes.

Those who reach the peak are also practicing the pinnacle of reconstruction. This climb will never stop.
