After many years of MWC exhibition, it is still the most international exhibition in the mobile phone industry every year. In this year's MWC 2017, there are still many new products and new technologies that shocked the world. They bring the industry not only now. Surprised and more is a predictor of future industry trends. Let us now let go of the hardware of the mobile phone to see what innovations manufacturers have in software technology. OPPO-leading photo If the most exciting new technology on the MWC is, then OPPO's "5x optical zoom" technology must be the first deserved, and now the dual camera is very common in many manufacturers' flagship machines, but Everyone has not come up with an effective way to use it. OPPO's 5x optical zoom released this time is also a major innovation in the field of mobile phones. The dual camera game of mobile phones can be said to be a kind of one, black and white + color; some people standard + wide angle; The iPhone 7 Plus is a standard + 2x zoom solution, but in actual use double zoom does not give users a lot of happiness, and the telephoto lens of the iPhone 7 Plus needs to be under certain circumstances. It can be turned on, it is really a little chicken. The OPPO's 5x optical zoom is very different. First, when the digital camera zooms to 5 times, the screen will be severely cut, resulting in a decrease in resolution. OPPO's innovative development of the periscope dual camera structure, through the built-in optical prism, like a periscope, allows the light to rotate 90° vertically when it encounters the prism, and enters the telephoto lens to achieve 5x lossless zoom. And the unique structure also guarantees the overall thickness of the lens set. While increasing the zoom magnification, OPPO controls the lens module to a value of 5.7mm, which is only about 3 coins. It is provided in today's thin and light mobile phones. great help. And on this telephoto lens, OPPO also added optical anti-shake, even when using the telephoto lens, the tension caused by the inertia of the muscles can be unstable. For the far-focus jitter, everyone should be deep. Experience, so OPPO's design is also to ensure the efficiency of imaging. In this era of double-flying, it can be said that it is a clear stream, which not only shows the company's practical ability for new technologies, but also lays a foundation for the future development of the industry. Huawei-Fingerprint Identification As a frequent visitor of MWC in recent years, Huawei naturally has new products. For example, this year's P series new P10 & P10 Plus mobile phones, although there is no innovation in the general direction of the two new machines, but in many details, people still talk about it, such as this time placed on the front Fingerprint recognition button. This is the second time Huawei has transferred fingerprint recognition from the back to the front. It seems that Huawei understands the benefits of being placed in the front, but it is worth mentioning that the fingerprint recognition of the P10 is not open in the front glass. That is to say, it is a whole piece of glass, which makes many people wonder if it is a solution using optical fingerprints, but this is not the case. According to industry insiders, Huawei P10 still uses capacitive fingerprint technology, which only partially thins and thins the front glass cover of the mobile phone so that the capacitive signal can penetrate. Although it is not a new optical recognition module, it is not easy for Huawei to do so, because the glass cover is partially hollowed out and thinner. The glass process requirements are higher than optical fingerprints. ZTE-5G Technology As the leader of the "China Cool Alliance", ZTE's voice volume in the field of mobile phone hardware has been getting smaller and smaller in recent years, but it is still the No.1 position in software technology. At this year's MWC exhibition, ZTE released 5G full range of high and low frequency pre-commercial base station products, and realized the 5Gbps high frequency base station 50Gbps peak rate at the exhibition site. The 5G high and low frequency series pre-commercial products exhibited at this exhibition support 3GPP 5G NR new air interface, support the industry 5G mainstream frequency band, adopt 5G such as Massive MIMO, Beam Tracking, Beam Forming, etc. Key technologies to meet the diverse scenarios and needs of 5G pre-commercial deployments. The advantage of 5G high-frequency communication is that the available frequency band is wide, the beam is concentrated, and the directivity is good, which is suitable for short-distance high-speed transmission of data. The 5G high-frequency base station released by ZTE supports 15GHz, 28GHz, 60GHz and other frequency bands. The low frequency band ("6Ghz" communication has an advantage over the high frequency band in terms of network coverage. ZTE's 5G low-frequency base station has high integration, small size and light weight, which is relatively convenient for engineering installation. And its working bandwidth is large, the single-station data throughput can reach 10Gbps. As early as 2016, ZTE has already carried out key technical verification of 5G high frequency and low frequency fields, and completed 5G high frequency field test. The 5G high and low frequency full range of base station products launched this time are ready for subsequent 5G pre-commercial testing and deployment. As one of the 5G key technologies, Massive MIMO plays an important role in improving frequency efficiency and air interface data bandwidth. At present, ZTE's Pre5G Massive MIMO has been deployed in markets such as China and Japan. And this time the development of 5G technology will provide dozens to millions of jobs for several top international countries. Sony-DRAM storage graphics sensor Although Sony said that the mobile phone business has gradually become low in recent years, it still has the status of world dominance in some core components. For example, the most indispensable camera for mobile phones, Sony can be said to monopolize the entire industry. Sony also used a new CMOS sensor on the Xperia XZ Premium released on this MWC 2017. This new CMOS adds DRAM layer to the original stacked CMOS, greatly improving CMOS data processing capabilities. With a pixel value of 21.2 million, it can shoot images up to 5520*3840 resolution. The CMOS diagonal length is 7.73 mm, the size is 1/2.3 inch, and the single pixel area is 1.22 μm. Supports reading 19.3 megapixel images in 1/120 seconds and shooting ultra-slow video up to 1000fps, which is a traditional Bayer array. This time Sony added a new DRAM layer (dynamic random access memory unit) between the pixel layer and the circuit layer. This part acts as a cache role in the entire CMOS module to store the image information acquired by the pixel layer, thus greatly improving the image. The speed at which the sensor processes the data. So Xperia XZ Premium can shoot 960fps slow motion video, I have to say that Dafa Black Technology is really unparalleled. Meizu - super charging technology Meizu also participated in the MWC exhibition for the first time. Although it did not release any new hardware products, it released its own fast charging technology. For the warm-up of this technology, Meizu was also a metaphor for the bombardment. Many other vendors. Although this is a bit not very good, but everything is based on products, it is understandable. Meizu's fast charge technology was named "Super mCharge", which achieved 5A/11V charging efficiency in specifications, which is much higher than the current QC 3.0 and VOOC flash charging. Super mCharge uses the industry's innovative charge pump technology with a conversion efficiency of up to 98%, which solves the problem of charging and heating caused by low efficiency. At the same time, the innovative architecture greatly reduces the heat generation, and the newly added E-Mark smart security chip is Charging safety provides dynamic protection. Summary - surprises but not bursts In fact, this MWC exhibition actually has a lot of innovations in the overall technical development, but more in some special functions, it has not provided guidance for future industry development. For example, OPPO's 5x zoom, although very innovative, will not be widely used in mobile phones in the future; Meizu's "Super mCharge" has yet to be tested in the market for many commercial features; although Sony is on CMOS Added memory, but the improvement in imaging quality is not great. In summary, although this year's MWC has some bright spots, it is not as breakthrough innovation as it used to be. Just like the current mobile phone industry, it has reached a bottleneck period. Who can break through this bottleneck, who will be in the future? Live the wind and the wind, and vice versa is to follow the footsteps of others.
