　　Huawei released the first 5G commercial chip and terminal.

　　As one of the largest annual exhibitions in the global communication field, there are many voices and highlights from China enterprises at this World Mobile Communications Conference. During the exhibition, Huawei released the first 5G commercial chip and terminal based on 3GPP standard, and ZTE and other companies also demonstrated their respective scientific and technological strength. According to the analysis, these new products mean that China enterprises are taking the lead in the field of 5G.

　　It is reported that Huawei’s 5G chip released this time — — Balong G5 G01 is the first 5G network product supported by the 3GPP standard. At the same time, Huawei also released Huawei 5G CPE, the first 3GPP standard 5G commercial terminal based on this chip. According to reports, the product is divided into two types: low-frequency (sub-6 GHz) CPE and high-frequency (mmWave)CPE. Among them, 5G low-frequency CPE can download an episode of online drama in less than 1 second, which can support various high-definition video and entertainment applications such as VR high-definition online video and VR online games based on 5G networks in the future, and is compatible with 4G and 5G networks. The release of Huawei’s first 3GPP standard 5G commercial chip and terminal is considered by the industry as one of the breakthroughs in 5G products, and it also marks the gradual opening of the 5G era at the industrial level.

　　"China has become the most dazzling star on the 5G stage" and "the world looks at 5G, and 5G looks at China". Relevant professional analysis points out that China’s communication technology has gone through the following in the 2G era, the participation in the 3G era, and the breakthrough in the 4G era. In the 5G era, China has successfully entered the first echelon.

　　pay close attention

　　5G smartphones will be available in the first half of next year.

　　In the terminal exhibition area of this conference, a conceptual mobile phone with ultra-high speed of 1.2Gbps also attracted a lot of attention. It is understood that this smart phone product, which is praised as "quasi-5G" or "pre-5G" by the industry, takes less than two seconds to download a high-definition movie.

　　It is worth mentioning that during the current Mobile World Congress, China Mobile announced that it would jointly launch the "5G Terminal Pioneer Program" with 20 terminal industry partners around the world. The plan aims to launch the first batch of 5G terminals as soon as possible in the early stage of the industry, promote multi-party cooperation and jointly establish a mature 5G terminal industry ecology.

　　According to reports, the plan has been widely responded and actively supported by the terminal industry, including 6 mainstream chip companies such as Qualcomm, Huawei, MediaTek, Ziguang Zhanrui, Intel and Samsung, and 10 mainstream terminal companies such as Huawei, OPPO, vivo, Xiaomi and Samsung.

　　China Mobile expects that all parties will make concerted efforts to launch the first batch of 5G chips that meet the needs of operators before the end of 2018, and release the first batch of 5G pre-commercial terminals, including data terminals and smart phones, in the first half of 2019. The analysis believes that this also means that many brands of 5G mobile phones are expected to be available in the first half of next year.

　　prospect

　　There are still about two years before the real outbreak of 5 G.

　　According to the plan of the Ministry of Industry and Information Technology, the three major domestic operators are expected to realize the scale commercialization of the fifth generation communication technology in 2020. According to the data, since 2013, China has taken the lead in launching the 5G test and R&D process. At present, China’s 5G commercialization process has been promoted in an orderly manner, and technology research and development testing has officially entered the third stage this year. The 5G field tests of the three major operators have been started one after another, and the pilot construction has been stepped up.

　　At the same time, a number of recent developments that have emerged since the second half of last year show that 5G promotion is accelerating. Industry analysts believe that although there are still about two years before the real outbreak of 5G on the commercial timetable, the wrestling of the 5G industrial chain has been fully rolled out. The analysis also pointed out that with the commercialization process of 5G network, it will drive the development of applications such as car networking, Internet of Things, drones and cloud computing, which means that 5G will not only become a new round of development opportunities for the global communication industry, but also create opportunities for the rise of various emerging information technologies.

　　The 5G economic report released by IHS, a market research organization, predicts that by 2035, 5G will create 12.3 trillion US dollars in global economic output and create 22 million jobs. Among them, China will have 9.5 million jobs, ranking first in the world, far exceeding the United States (3.4 million).

　　The White Paper on the Economic and Social Impact of 5G issued by relevant institutions in China also pointed out that 5G, as a general-purpose technology, will open up a new era of mobile communication development, accelerate the process of economic and social digital transformation, and push the development of China’s digital economy to a new level. The white paper predicts that the direct output and indirect output driven by 5G will reach 6.3 trillion yuan and 10.6 trillion yuan respectively in 2030. In terms of direct output, according to the official commercialization of 5G in 2020, it is estimated that it will drive about 484 billion yuan of direct output in that year, and it will increase to 3.3 trillion yuan and 6.3 trillion yuan in 2025 and 2030 respectively, with a compound annual growth rate of 29% in the past ten years. In terms of indirect output, in 2020, 2025 and 2030, 5G will drive 1.2 trillion yuan, 6.3 trillion yuan and 10.6 trillion yuan respectively, with a compound annual growth rate of 24%.

　　News memory

　　5G can finish a 1080P movie in a few seconds.

　　What is 5G? The relevant technical specifications of the International Telecommunication Union (ITU) have identified eight key capability indicators for 5G. According to reports, the peak rate of 5G in the future can reach 20Gbps. Other capability indicators include user experience data rate of 100Mbps, delay of 1 millisecond, connection density of 1 million devices per square kilometer, and traffic density of 10Mbps per square meter.

　　"Compared with the current mainstream 4G communication, 5G brings the most intuitive benefits to users. In addition to improving the quality of calls, that is the transmission rate." Relevant professionals pointed out that the speed of 5G network can reach the level of Gbps or even tens of Gbps, which means that a movie in 1080P format can be downloaded in a few seconds. In addition, 5G communication also has the characteristics of low power consumption and high access, and has become an important foundation for the development of the Internet of Things.

　　"For enterprises, 5G will create value for many fields, such as automobile transportation, energy/utility monitoring, security, finance, medical health, industry and agriculture, especially for large-scale and key application fields that require low latency. For consumers, the highlights of 5G services will be concentrated in two aspects: ultra-high-definition video applications and AR/VR applications. " According to the relevant report of GSMA, it is estimated that by 2025, 5G networks will be commercialized in 111 countries and regions around the world. After the early deployment, the 5G network will provide enhanced mobile broadband services with high speed, low delay, reliability and security.

　　However, professionals also pointed out that in order to enjoy the convenience brought by 5G communication, consumers also need a terminal that supports it. At present, mobile phones in the hands of ordinary domestic users are not yet supported. "The arrival of the 5G era is bound to set off a new round of replacement boom." The above-mentioned person said.

　 　 As of September 2013, (|) Car Series has sold more than 340,000 cars in Europe, firmly occupying the top spot in European car sales. Not only is it sought after by consumers, but also by car media people. After winning the 2013 World Car Award and the 2013 European Car of the Year award, even the Japanese media, which has always protected the calf, awarded the 2013 Japanese Car Award to Golf 7.

　 　 What is the charm that makes Golf 7 so sought after? Can the domestically produced Golf 7 maintain the same quality? How does the torsion beam suspension affect the handling and comfort of the vehicle? Today, we will find the answer through detailed experience and professional tests. Before entering the detailed evaluation, let’s take a quick look at some questions about Golf 7.

Where is Golf 7 new? What’s the difference with Golf 6?

1. New platform: upgrade from PQ35 platform to MQB platform (transverse engine modular platform).

　 　 What benefits can the new platform bring? This starts with understanding the differences between the two platforms. Generally speaking, PQ35 platform is a platform that can only produce and develop compact cars (cars, SUVs, MPVs, etc.), while MQB platform can produce and develop small cars, compact cars and medium-sized cars (horizontal engine models).

　 　 Broader derivatives mean more spare parts can be shared. According to the official introduction, products from the same module platform of MQB can share the same specifications of engines, gearboxes and air conditioners, and the sharing ratio is about 60% of the whole vehicle parts, thus greatly saving the development cost of new cars.

2. New design: the game between inheritance and innovation

　 　 For the public and golf, brand recognition and the retention of traditional elements are often paid great attention to in design. This creates a lot of difficulties for designers, not only to make it look new and beautiful enough, but also not to leave behind the necessary contents such as "public face" and "golf element".

　 　　Compared with the 6th generation, the lines of Golf 7 are tougher and sharper, and at the same time, the proportion of details of the body has been adjusted a lot. For example, lowering the car body and increasing the car width can make the golf 7 look more dynamic. Compared with the 6th generation, the interior of the vehicle has also added more sense of design. The introduction of asymmetric design and the addition of piano paint are all aimed at giving people a sense of freshness and grade.

3. new power: EA211 high-power version has excellent performance

　 　　All the departments of Golf 7 will be equipped with EA211 engines, in which the parameters of 1.6L engine and 1.4T low-power engine are slightly improved compared with the current ones, while the EA211 high-power model we got has a maximum power of 150 HP and a peak torque of 250 Nm, which is not small improvement compared with the current 131 HP and 220 Nm.

　 　 Our measured 0-100km/h acceleration time of Golf 7 1.4T high-power version is only 8.20 seconds, and its performance is comparable to that of (|) and (|) with 1.6T engine. Compared with the performance of the 6th generation of 9.22 seconds (measured in car home), it has improved by one second, and it is at the leading level in the same level.

4. New suspension: The rear torsion beam suspension becomes a hot spot again.

　 　 As soon as the domestic Golf 7 came out, the change of the rear suspension once again became the target of public criticism. First of all, it can be affirmed that this is indeed a practice to reduce costs, regardless of what space is saved, because the seating space of Golf 7 is exactly the same whether it is equipped with torsion beam suspension version or multi-link suspension version.

　　　 What really makes people feel uncomfortable is that the 1.4T high-powered version is not spared. You know, in Germany, this version is a genuine multi-link. Fortunately, from the actual driving experience, Golf 7 does not decline in sports, but rises. The tighter suspension has stronger toughness than the sixth generation when cornering, but the comfort is weakened a lot, especially when riding in the back row. The feeling of vibration is very obvious.

5. New configuration: electronic handbrake, automatic parking, engine start-stop and adaptive cruise set a new benchmark.

　 　 The Golf 7 comes standard with an electronic handbrake and an AUTOHOLD automatic parking system. No matter in the configuration list or in use, there is a feeling that the competitors at the same level are superior. However, in actual use, the simultaneous starting and stopping of the engine and automatic parking will really affect some comfort, which will be discussed in the configuration part later. Let’s sell it here first.

　　　　Engine start-stop and adaptive cruise belong to the high-altitude configuration, whether it appears on high-equipped models or optional, and the manufacturer has not yet made it clear. There is nothing to say about starting and stopping, but the new version of the adaptive cruise system is eye-catching, and it basically realizes the "follow-up function". Not only can you stop with the front car when you encounter a red light, but you can also continue to follow the front car when you start again.

6. New entertainment system: MIB Standard Plus video details.

　　　 With the overall upgrade of the interior, the car entertainment system has also been replaced by the MIB Standard Plus. In fact, its sales are really average, because the screen size is only 5.8 inches, which is slightly larger than the 5.5-inch screen of Samsung Note2. Of course, the resolution is much worse. The function of the system is comprehensive, but the reaction speed is average.

What versions of Golf 7 will be available? What version is our test car?

　 　 In terms of power, the future Golf 7 will be divided into 1.6 and 1.4T displacement, of which the 1.4T engine is divided into high-power version (110 kW) and low-power version (96 kW). Among them, the 1.6L and 1.4T low-power versions will become the main sales force, while the 1.4T high-power version may only have 1-2 models.

　　　 Judging from the known information given by the government, the future Golf 7 can be divided into fashion type, comfort type, luxury type and flagship type, which is similar to the layout of the current six generations. Fashion models should only be available in 1.6L models, while the configuration of the flagship model is prepared for the 1.4T high-power version. According to the experience of the 6th generation, comfort and luxury will still be the main sales force. Before the price is announced, you can make a calculation according to the configuration.

　 　 Our test car is a 1.4T high-power version of the flagship, which represented the strongest strength of domestic Golf 7 before the 7th GTI went on the market. Can Golf 7 set a new benchmark? In the next evaluation, we analyze them one by one.
