With the arrival of 5G, maintaining 4G, 3G, 4G, and 5G networks will become a huge burden for operators. How to help operators to easily play in the 5G era, while providing the original network capabilities, but also make the network more efficient and convenient, which requires the bridge to build 4G to 5G before the arrival of 5G, now it seems that 4.5G It is this bridge. Let's take a look at the related content with the network communication Xiaobian. “For the new business, behind the technology, the ecological support, and the transformation of the capabilities of the operators, these are the problems that need to be solved before the real 5G commercial scale. From a technical point of view, the 4G network will become the operator. To build a basic network. From the operator's point of view, in order to achieve 5G leadership, we must cultivate and build new business capabilities in advance on the 4.5G network.†Huawei LTE product line president and president of the wireless vehicle networking product line Xiong Wei said. Today, the penetration rate of traditional business operators in most countries around the world is already high, and there is not much potential to be tapped. For operators, only efforts to achieve breakthroughs in new areas are expected to achieve new revenue growth. “This year, everyone is talking about the vertical industry. This is a blue ocean market, which will become the basic capability for future industrial upgrading. Operators can develop their business by promoting the upgrading of the industry, thereby gaining more opportunities and achieving revenue growth.†Xiong Wei said. "However, the existing network cannot support these emerging businesses, which is why we have repeatedly stressed the importance of 4.5G." Xiong Wei said. Xiong Wei believes that 5G networks must be commercialized at least for 3-5 years. During this time, 4G is not enough, 5G is not used, operators want to force the emerging business market, the best solution is to deploy 4.5G network, so that the network can support rich vertical applications, such as 4K video, Virtual reality (VR), augmented reality (AR), driverless and Internet of Things, etc., to cultivate and build full-service capabilities, to gain 5G first-mover advantage. At the same time, 4.5G can also help operators adapt their network structure, and prepare for the subsequent rapid upgrade to 5G. Xiong Wei explained that there are many technical differences between 4G and 5G. Deploying 4.5G can help operators smoothly transform their networks so that they can adapt to future 5G deployments and cultivate users' interest and habits in 5G applications. So, in the era of 5G, how long can the life of 4.5 be? Xiong Wei believes that 4.5G and 5G will coexist for a long time. In fact, today, after years of commercial use at 4G, only 30% of global wireless base stations are 4G base stations; many 4G frequency points are currently distributed globally, averaging two to three in each country, but so far The country has only built a frequency point, there is still a huge space; many users still use 2G, 3G terminals, and need to gradually migrate to 4G; in addition to a small number of hotspots, 4G services still have huge upside in a large number of regional markets; Even in areas with high levels of information technology applications, the entire business is in its infancy, and from network capabilities to business development, it is far from reaching its peak. In terms of terminals, after several years of efforts, the cost of 4G chips is only one dollar more than that of 3G chips, and it has a basis for large-scale promotion. "Based on the above points, we can see that 4G still has huge potential. We believe that it will remain the golden decade of 4G in the next decade. 4G will continue to maintain rapid growth, and most operators around the world share the same view." Xiong Wei said. "On the other hand, for operators, operating 2G, 3G, 4G or even 5G networks at the same time is not only very costly, but the capabilities of multiple networks are overlapping and unnecessary." Xiong Wei said, "So, the future The basic network must be based on 4G networks and gradually build 5G networks according to business needs." As the initiator of 4.5G, in October 2015, the technical specifications proposed by Huawei were named as LTE-Advanced Pro by 3GPP, and the concept of 4.5G was recognized by the authoritative standardization organization. Today, 4.5G has been commercialized on a global scale. As of July 2017, a total of 68 4T4R commercial networks have been deployed by global operators. There are also a number of flagship models supporting 4R terminals on the market. Huawei deployed 100 4.5G commercial networks around the world and deployed VoLTE to 109 operators in 57 countries. The facts show that after deploying 4.5G networks, many operators around the world have significantly improved their network capabilities, and their network experience rankings have increased dramatically, attracting a large number of new users. Under the efforts of Huawei, the performance of the 4.5G network is still improving. Recently, Huawei and the British operator EE successfully completed the testing of 4.5G LTE-Advanced Pro related technologies. Under the commercial network of EE dual-band 4T4R, Huawei Mate10 Pro measured downlink peak rate of 970Mbps, which is more than six times the peak rate of 4G of 150Mbps, which is the fastest commercial peak rate to date. At the just-concluded 2017 Global Mobile Broadband Forum, the guests watched the flight demonstration of the manned drone based on the 4.5G commercial network. The UAV's over-the-horizon control and data transmission performance were amazing. Xiong Wei said that this is the “Digital Sky Plan†being developed by Wireless X Labs, a Huawei wireless application scenario lab. It covers the innovation of drone applications through low-altitude network coverage, enabling low-altitude digital industrial economy. "4.5G and 5G will coexist for a long time and will play an important role." Xiong Wei finally stressed that "At this stage, 4.5G can be reserved, 5G basic capacity can be reserved in advance, 5G business can be ripened, and user habits can be cultivated to ensure Take the lead when 5G arrives." 7.5 Mm Nano Tip,Smart Pen Infrared,Infrared Pen Touch,Slim Infrared Pen Shenzhen Ruidian Technology CO., Ltd , https://www.szwisonen.com
