Status of 5G development of Chinese manufacturers and other countries on MWC
The annual World Mobile Communications Conference is staged in Barcelona this year. As the most important annual event in the communications industry, the communications giants in the industry will not miss it. Every year, MWC is the time when manufacturers show their strongest technology. . Let's take a look at the related content with the network communication Xiaobian. Of course, although there is no black technology that is amazing for this MWC, it is still the previous 5G and artificial intelligence technologies. It is a bit of a commonplace, but the emergence of these technologies is enough to surprise people. Technology has begun to land and is about to be commercialized. As the important connecting tool of the Internet of Things in the future, 5G's development is related to the fate of many enterprises, so every move is concerned by the relevant industries. In the 5G field, Chinese companies are laying out early, and giants such as China Mobile, Huawei, and ZTE have been studying 5G for a long time. The Ministry of Industry and Information Technology has clearly pointed out that the domestic 5G commercial technology will be realized in 2020. On January 2 this year, the Ministry of Industry and Information Technology held the third phase of the 5G technology R&D test review meeting, which also means that China's 5G network has entered the pre-commercial stage. . At present, the three major mobile operators in China are also stepping up to build a domestic 5G pilot. Everyone who is participating in MWC is also making a big impact. Huawei released the world's first 3GPP standard 5G baseband (Ballon 5G01) at MWC with a peak rate of 2.3Gbps and supports Sub6GHz and mmWave multi-band solutions. Qualcomm's previously released 5G baseband X50 uses 28GHz mmWave. In addition, Huawei also released a 5G commercial terminal based on the Barong 5G01 baseband, Huawei 5G CPE. This CPE is mainly used to convert 5G signals into Wi-Fi devices, mainly for enterprise customers, and ordinary consumers should not use them. Huawei 5G CPE is classified into low-frequency (Sub6GHz) CPE and high-frequency (mmWave) CPE. Among them, the 5G low-frequency CPE measured the peak downlink rate of 2Gbps, which is equivalent to 20 times of 100M optical fiber. It can download a set of network dramas in less than 1 second, and is backward compatible with 4G networks. In addition to Huawei, ZTE also demonstrated its 5G technology at the exhibition. And ZTE terminal also brought ZTE 1.2Gbps mobile phone. It is planned to release 5G commercial mobile terminal at the end of 2018 or early 2019. 5G tablet PC, CPE and smart phone are all in commercial R&D. The specific time to market will be related to the world top. The carrier 5G network is commercially matched. It is worth noting that ZTE and Qualcomm and China Mobile jointly conducted the 5G three-party IoDT demonstration, which can be regarded as an important industry milestone for realizing large-scale rapid verification and commercialization of 5G new air interface technology in the industry. Although there is still a gap between the sales of ZTE mobile phones and the top brands in the current smart phone manufacturers, like Huawei, ZTE is also the backbone of the communications field, driving the development of 5G networks. China Mobile Chairman Shang Bing also announced at MWC that the world's largest 5G trial network will be built in 2018. It plans to conduct field tests in five cities including Hangzhou, Guangzhou, Suzhou, Shanghai and Wuhan. Each city will build 100. Above 5G base station. In addition to China, companies in other countries have made many achievements in the 5G field. For example, on the first day of MWC, Intel announced that it will cooperate with Dell, Hewlett-Packard, Lenovo and Microsoft to introduce 5G into Windows PC based on Intel XMM8000 series commercial 5G modem. It is understood that this 5G fully interconnected PC (5G-connectedPC) will be available in the second half of 2019. Qualcomm also highlighted a number of results from its extensive 5G real-world network simulation experiments conducted over the past few months at MWC. In a hypothetical NSA5G new air interface network test in San Francisco, USA, the network connection operates on a 28 GHz millimeter wave spectrum with a bandwidth of 800 MHz. Tests show that browsing download speeds have increased from 71 Mbps for 4G user averages to 1.4 Gbps for 5G users within millimeter-wave coverage, achieving nearly 2000% gain. Take a 1G movie as an example, you can download it in 5 seconds. In addition, Ericsson has also made some achievements in 5G. So far Ericsson has completed the construction of 5G platform, including 5G core network, wireless network and transmission network products, as well as OSS, BSS, network services and security products. Although many companies have already poured into the field of 5G, at present, it will take several years for 5G to completely change our lives. After all, the 5G network in China has just begun, and 5G still lacks killer applications. Therefore, at present, 5G can only be used in a small range. Some time ago, the PyeongChang Olympics in South Korea also relied on 5G for data dissemination and output 8K video, which are some of the scenarios that 5G can currently use. The evaluation report of relevant institutions shows that the current 4G network in South Korea is showing signs of weakness, and the first signs of capacity bottlenecks mean that 5G is not only the technology that operators and related companies are eagerly awaiting, but also the demand of the network itself. However, in the field of 5G, China has already seized the opportunity and shakes the initiative. In this era of leading, step by step, this advantage is self-evident. Only how to maintain this advantage requires the joint efforts of the domestic industry. The world's martial arts, only fast, not only broken, only more innovation, in order to keep themselves behind. 210W Medical Power Supply,210W Medical Device Power Supply,210W Medical Power Adapter,210W Rade Power Supplies Shenzhen Longxc Power Supply Co., Ltd , https://www.longxcpower.com
