After becoming a leader in the wireless field, Huawei has taken on a huge responsibility in the process of 5G promotion. Currently, it is at the critical stage of the development of 5G. Huawei’s latest Mate 10 Pro equipped with Kirin 970 chip is the largest. It can support a peak rate of 1.2 Gbps and achieve Gbps. At the Huawei Mate 10 series launch conference in Munni, Germany, a video of “The Fastest Mobile + Fastest Network†caused a lot of surprises – at the Wembley Stadium in the UK, Huawei and EE use Mate 10 Pro on the live network. In the mid-measurement of the peak rate of 970 Mbps, while demonstrating the powerful data connectivity of the new generation of Mate, it has once again proved that the 4.5G has greatly improved the network experience. "4.5G has two maximum values. One is to meet the operator's current user experience upgrade appeal. The real arrival of 5G still needs a certain period. After the completion of the standard, it will also undergo the industrial chain maturity and scale construction. The second is to hatch the future. By 2025, there will be more than 100 billion connections in the world. In order to meet the digitalization process of the all-connected world and participate in all walks of life, operators must cultivate their team, ecosystem and commercial construction capabilities from now on. Therefore, it It will be the only way for the industry to move towards 5G, and will coexist with 5G for a long time in the future; and Huawei's goal of 4.5G is to incite operators to continue their business success." In a media exchange at the Institute, Huawei's president of wireless network research and development should face the C114. Today, with the design and function of mobile phones becoming more and more homogeneous, the network experience is gradually becoming the focus of consumers. Not only Huawei, Samsung and Xiaomi's flagship aircraft released this year have also announced that they can support 4x4 MIMO technology. "4x4 MIMO from the perspective of consumer understanding, that is, the download rate can be increased by 2 times. For example, 1080P video has now become mainstream in video sites such as Youku. In indoor weak coverage scenarios, 2 mobile phones with receiving antennas may only Can watch 720P and below videos, but 4 receiving antennas can watch 1080P mobile phones; everyone is playing the real game like King Glory, or when grabbing red packets, who has higher network speed and smaller delay, it is easier Get an advantage." It should be said to the people. On the network side, 4x4 MIMO corresponds to 4T4R - it is a key feature in 4.5G and will be the starting point for 5G networks. Compared with terminals, the network is generally more advanced, and 4T4R has become the actual LTE network construction standard. The mainstream operators in the world regard it as one of the important directions of network evolution. As of July this year, only Huawei has deployed 68 4T4R networks for operators, and 4T4R technology has been applied to the EE live network test at Wembley Stadium. “Spectrum is an inanimate resource. In some countries, the spectrum is also very expensive. How can it greatly improve efficiency in a limited spectrum?†The role of 4T4R is mainly reflected in the improvement of spectrum efficiency and the resulting capacity increase. Compared with LTE, the downlink capacity can be increased by 1.2-1.8 times, and the uplink capacity can be increased by 1.25 times, thereby fully supporting the large-capacity demand of the network for outdoor hotspots, large venues, and homes. From the perspective of operators, deploying 4T4R can improve the experience from the cell center to the cell edge; it can improve the experience from peak rate to average capacity; it can also enhance the experience from outdoor to indoor, allowing users to feel seamless. Scene high speed internet experience. More importantly, due to the significant improvement in user experience, 4T4R can bring business and brand breakthroughs to operators in complex competitive environments. Take Turkcell as an example. The operator and Huawei jointly launched the 4.5G commercial network on April 1, 2016 and completed the 4T4R deployment in November. The monthly user usage (DOU) grew rapidly within half a year. Compared with the same period of growth of 63%, data business revenue increased by 97% year-on-year, ranking first among Turkish operators, and this year won the P3 test Turkey's first performance. Coincidentally, Thailand's True Move and Huawei jointly deployed the world's largest 4T4R network in 2016, with a total scale of more than 6,300 sites. True network statistics show that compared with the traditional 2T2R network, the average throughput of 4T4R cells has increased by 20%, while the cell edge throughput has increased by 40%, thus helping True to seize the opportunity in the mobile operation competition in Thailand. The stock price has risen by 20%; today, True has become the country's second largest mobile operator. "This year is a year of rapid development of the 4T4R industry chain. The mainstream chips of HiSilicon, Qualcomm and Intel have already supported 4x4 MIMO. In addition to Huawei, Samsung, Sony, Xiaomi, etc., there will be more and more brands of mobile phones will be 4x4. MIMO as a standard, whether it is a low-end model will have this feature by default, network Ready plus terminal Ready, will inevitably spark a more beautiful spark, bringing consumers unprecedented network experience." Evaluation. Today, Gbps has become the new mobile broadband network speed standard, the commercial deployment of VoLTE has been rolled out globally, and the Internet of Things technologies such as NB-IoT/eMTC/LTE-V have also fully opened up the industrialization process. 4.5G is rapidly changing. People's way of life, and even change the entire human society. While 4.5G can quickly complete the process from concept to mass commercialization in just a few years, Huawei, as the initiator and main promoter, is obviously indispensable. "The 4.5G concept is discussed in the office we are sitting in now." It should be pointed out that the generation of a generation technology will generally take ten years, just as 2G to 3G has GPRS, 3G to 4G has HSPA/HSPA+/ Like DC-HSPA+, 4G and 5G also need such a bridge to help operators meet the growing experience of consumers, and explore and nurture new experiences, new services and new business models for 5G, 4.5G by This came into being. In October 2014, Huawei took the lead in proposing the 4.5G concept in the industry; on February 24, 2015, it released the 4.5G business blueprint in London, UK and demonstrated the application of 4.5G in the industry to fully explain the development prospects and directions of 4.5G; 2015 In October, 3GPP officially decided to name the new 4.5G standard as LTE-Advanced Pro at the 35th meeting of PCG; in December 2015, TeliaSonera and Huawei released the world's first in Oslo, Norway after 6 years of commercialization of 4G. 4.5G commercial network, the peak rate of the existing network reaches 1Gbps; during the World Mobile Communications Conference 2016, the company held 4.5G together with many leading global operators such as Norway TeliaSonera, Hong Kong HKT, South Korea LG Uplus, Poland P4, Kuwait VIVA, etc. The strategic cooperation launch ceremony symbolizes the official launch of the 4.5G global scale commercial. At present, Huawei has helped operators deploy more than 100 4.5G commercial networks worldwide. But at the same time, the 4.5G proposed to commercial is not without twists and turns, but also encountered some doubts. Among them, Huawei not only has to submit a large number of normative documents for the 4.5G standard formulation, communicate with all parties in the industry chain or even competitors to form a synergy, but also to mature the core technology and the entire end-to-end industry chain and promote the formation of the ecosystem. In addition, 4.5G will enter the vertical industry and open up new market space. In addition to the contributions of operators and telecom circles, vertical industry players will also be involved. Huawei has held various summit forums to provide cross-border exchange opportunities and actively cooperate with international organizations. The upstream, downstream and vertical industries of the industrial chain will cooperate to form an industrial alliance. "We are doing the push to promote 4.5G with the heart of entrepreneurship." In the view of the people, Huawei must take on more responsibilities and pay more for the industry after becoming a leader in the wireless field. For example, it has made various efforts in the Internet of Things corresponding to 4.5G, and even invested in a chip company (Neul) to achieve a rapid increase in terminal size. He also stressed that 4.5G/LTE Advanced Pro is not the last stop to 5G, there will be continuous evolution in 3GPP R15/R16, and will coexist with 5G for a long time - at least in the next five to ten years, will still Give full play to the role of the main base and the main cash flow, "Ying can win the future in the present." At the end of 2017, the first phase of the first version of the 5G NR will be completed by the end of 2017. Relevant technical tests and network verification have also started. Huawei believes that in order to take the lead when 5G arrives, operators must plan their target network in advance. "The future network must be multi-frequency, multi-mode, multi-standard, and three-dimensional networking. How to manage such a complex network and meet the complex business of the future is something that operators should pay special attention to today." For 5G, operators should be fully prepared for user experience, network architecture and business gestation. First of all, in terms of experience, Gbps is the standard in the 5G era, but Gbps can also be realized today through a combination of multi-antenna technology, multi-carrier aggregation, and high-order modulation technology. Huawei's latest Mate 10 Pro with Kirin 970 chip can support a peak rate of 1.2 Gbps; 4T4R is the base network for Giga experience, 8T8R is the best practice for high-capacity networks, and Massive MIMO can improve single-station 40MHz Bandwidth cell to 5Gbps capacity. In terms of architecture, a comprehensive cloud-based network structure and a hardware platform supporting smooth evolution will implement Ready for 5G evolution architecture. In terms of business gestation, operators can use 4.5G full-service to advance their business in advance, such as Internet of Things, high-definition video, AR/VR, drones, etc., but also need to strengthen guidance and advancement in the industry chain, such as 4 receiving antenna mobile phones, Internet of Things terminals, etc. Just before the 2017 China International Information and Communication Exhibition, Huawei released the concept of a full-service minimalist network. The so-called "full service", that is, the Internet of Things, VoLTE, WTTx, car networking, sTTI low-latency services, etc. can all be carried over the LTE network; "minimalist" is embodied in the architecture, site, indoor, equipment, operation and maintenance, etc. Levels, such as full cloudization on the architecture, All in One antenna on the site, and Lampsite in the room. According to Xu Xuebing, vice president of Huawei's wireless network LTE product line, in a media interview, a full-service minimalist network will have five characteristics: the full spectrum will move toward 4G, releasing the network 20+ spectrum potential; Faster deployment and lower cost; more network capabilities, enabling LTE better performance; operation and maintenance capabilities tend to AI, enabling future intelligent operations; solution 5G, enabling LTE future evolution.
