Qualcomm recently held a 4g/5g conference in Hong Kong, announced its new 5G chipset, the first 5G smartphone reference design and related 5G technology layout, can see this conference is mainly about 2019 years to achieve 5G commercialization, in fact, from this Congress also learned 9 things, will help to learn more about 5G technology. According to the Mobile Network website, one, Qualcomm's recent preference for telecommunications operators to disclose that they do not need to find, equip and deploy a large pile of new base stations, can be from the mmwave point of access to a fairly good coverage of the technology, Qualcomm RF (RF) The delivery analogy can reach 75% coverage by deploying Mmwave pointcuts in the LTE base. This type of announcement has been published several times, which shows that Qualcomm hopes to defuse the perception that 5G Mmwave will have to require very little coverage and therefore need to build more base stations. Qualcomm wants to see telecoms operators embrace mobile mmwave, giving Qualcomm the opportunity to leverage its mobile-device hierarchy, and Qualcomm will also have a lot of intellectual property (IP) in the infrastructure layer, thanks to its research and development efforts in Mmwave RF behavior. Secondly, as to how to build a 5G environment for 5G Air Interface Technology, senior vice President Durga Malladi said this includes the need to import optimized orthogonal multi-frequency Division (OFDM) waveforms in almost all scenarios to preserve some proprietary applications (apps), such as deployment in the IoT (IoT) The device's resource extended multiple access (RSMA) technology, ME-LDPC coding, can provide multiple services in the same frequency of the elastic sub structure, and into large-scale multiple input multiple output (massive MIMO) technology. Third, the reason for the above content is important, the current 5G standard is still not formed, and Qualcomm is already promoting 5G NR modem chips and supporting RF modules to support a reference design for the size of a smartphone, based on the use of the integrable circuit (ASIC) rather than on-site programmable gate Array (FPGA), If the empty mediation surface changes, there will be a problem with the hardware redesign. For this Qualcomm chip business President Cristiano Amon pointed out that many of the hardware is now consistent and allows the industry to move forward, and that the future will continue to see changes as standards evolve, but on this point Qualcomm is confident that its X50 chip design will conform to the R15 standard to support sub 6GHz and Mmwave. Its four, compared to mmwave Wi-Fi, mobile mmwave has a very different power efficiency curve, so Qualcomm believes that the use of greater bandwidth formation of higher transmission capacity, will be able to actually obtain more efficient use of power, which is mainly related to overcoming mmwave defects. Five, senior vice president of Qualcomm Spectrum strategy and technology policy, Dean Brenner, said in the meeting, all spectrum can be used for 5G, including authorization, unauthorized and shared spectrum, this will help to privatize the network and the development of authorized operators ' networks, which will be part of the specification in the non-authorized independent mode 5G, Instead of being excluded from 3GPP, other spectrum-sharing technologies are possible. Its six, the mainland 5G development is also not negligible, the mainland has entered the third phase of 5G technology testing, these government-led testing is now from the validation of individual technology use cases, to study more integrated system design, from the core to the near-use layer of interaction and transmission issues. The third phase of the Continental 5G test will begin in 2018. In its seven, Mike Wright, general manager of Telstra Network Group, said the industry must better explain to each other why 5G has its differences, and 5G is able to develop in the areas of applications that cannot be touched by 4G, which requires client-side use cases. Its eight, although 5G commercial deployment is now very hot, but not most of the global telecommunications operators can begin to deploy in 2019, such as mainland China Telecom (Telecom) estimated that 2020 years before the deployment of 5G, However, South Korea's KT Telecom is planning to launch some 5G deployments in 2018 to keep up with the date of the South Korean Winter Olympics. Finally, Qualcomm's LTE pro, known as ' Gigabit LTE ', will be the key support for 5G development.
