Chinese mobile phone manufacturers such as OPPO, vivo, and Xiaomi have successively announced the development of commercial 5G smartphones. According to the research and development schedule of the three mobile phone companies, 5G mobile phones will meet with consumers as soon as next year. On September 3, Xiaomi (01810.HK) announced that Xiaomi's mobile phone had successfully opened up 5G signaling and data link connections on August 31. This is also an important development of Xiaomi's 5G research and development process. This connection uses Qualcomm Snapdragon X50 5G modem and supporting radio frequency solutions, and has made targeted optimizations for mobile phone motherboard stacking and radio frequency/antenna design, laying a solid foundation for the official launch of 5G mobile phones in 2019. Previously, on August 28, OPPO Guangdong Mobile Communications Co., Ltd. announced that the company successfully completed the 5G signaling and data link connection based on commercially available mobile phones. This connection is realized using a commercially available 5G smartphone based on OPPO R15, which integrates the Snapdragon X50 5G modem, which validates related technologies that can be used to accelerate the development of 5G smartphones. Liu Chang, president of OPPO Research Institute, said that this will lay the foundation for the release of commercial 5G products in 2019. On August 30, vivo announced that based on the latest flagship mobile phone vivo NEX platform, vivo has initially completed the development of commercial 5G smart phone software and hardware, including architecture planning, motherboard stacking, radio frequency and antenna design, and optimization of battery space. , And has reached the commercial level in size and appearance. Next, vivo 5G mobile phone is about to enter the stage of joint debugging and testing with network equipment. According to previous plans, in 2019, vivo will launch 5G pre-commercial mobile phones. By 2020, with the large-scale commercialization of China's 5G network, vivo will officially launch 5G commercial mobile phones. At the technical level, The Paper reporter noted that both Xiaomi and OPPO have adopted the 5G NR n78 frequency band, which is currently one of the most widely used and first deployed frequency bands in the world, and is of great significance to the commercialization of the first batch of 5G products. 5G NR (New Radio), or 5G New Radio, is a wireless signal transmission specification specially formulated for 5G by international standardization organizations such as 3GPP. As an important node for communication technology updates, 5G will comprehensively improve network speed (the theoretical download speed is more than ten times faster than 4G), stability, reliability and low latency, including 3D communication, 4K+ ultra-high-definition video viewing, and online New experiences such as AR/VR, cloud office, and cloud gaming. With the International Telecommunications Standardization Organization 3GPP in December last year and June this year respectively freezing the non-independent networking (NSA) and independent networking (SA) standards, 5G industrialization ushered in a full sprint. Chinese mobile phone manufacturers have invested in R&D in the 5G field for some time. In 2016, vivo established a 5G R&D center in Beijing to participate in the research of 5G core technical standards. In 2017, vivo has become one of the mobile phone companies with the largest contribution to 3GPP technology. In 2017, vivo initiated pre-research on key technologies of 5G antenna and radio frequency. In terms of the productization of 5G mobile phones, vivo also cooperates with telecom operators and chip solution manufacturers to jointly promote the development of 5G prototypes and commercial mobile phones. OPPO has invested in the 5G field since 2015. In May of this year, OPPO announced that it had successfully implemented the world's first 5G video call demonstration using 3D structured light technology, and the FPGA-based prototype verification platform successfully demonstrated the peak transmission rate of 1.4Gbps in downlink and 160Mbps in uplink, promoting the industry's new 5G applications And the exploration of the terminal form. Before the 3GPP started to discuss the 5G standard, Xiaomi set up a pre-research team to start research on the 5G standard in advance. Xiaomi participated in the formulation of the 5G standard. As the convener, Xiaomi led the discussion of some technical topics and led the formulation of some technical directions. Xiaomi is also one of the few terminal companies in the industry with 5G simulation capabilities. At present, Xiaomi has a leading edge in the research and development of new 5G technologies, especially millimeter wave antenna arrays. Xiaomi is still exploring the application of NB-IoT in smart home scenarios. In the domestic market, Xiaomi has signed a 5G-related memorandum with China Mobile. According to the plan of the Ministry of Industry and Information Technology, it is expected that the first batch of 5G chips will be taped out before New Year's Day in 2019, and will be completed around the Spring Festival; commercial base stations will be constructed in the first half of 2019, and the first batch of 5G mobile phones will be produced in the second half of the year. In this way, the 5G plans of domestic mobile phone manufacturers also coincide with the time nodes planned by the Ministry of Industry and Information Technology and operators' testing. In addition to the aforementioned manufacturers, Huawei also announced that it will release the first mobile phone that supports 5G network frequency bands in the second half of 2019. According to a report previously released by the market research company Counterpoint Research, 5G smartphones will enter the initial commercialization stage in 2019. After the initial slow growth, they may show an explosive growth trend in 2021, and shipments will exceed 110 million units. all in one energy;all in one battery,home battery,home energy storage,household power storage,home solar power,all in one system Shenzhen Enershare Technology Co.,Ltd , https://www.enersharepower.com
