On February 25th, the annual mobile world conference (MWC 2019) officially opened in Barcelona, 5G mobile phones became uncontrust in the biggest highlights. Behind the mobile phone manufacturer, actually standing a silent hero - it is Qualcomm. As an industry pioneer, Qualcomm released the industry's first 5G modem (ie, baseband) Xiaolong X50 upcoming 5G support the world's first commercial mobile phone market. At the time of this batch of 5G mobile phones, Qualcomm has launched the second generation of 5G baseband - Snapdragon X55.
While providing support for the next generation of 5G mobile phones, this new platform can also bring advanced 5G connection capabilities for many forms of terminal equipment such as PC, cars. In fact, the Snapdragon X55 is not the only big trick that Qualcomm is released on MWC. Qualcomm also launched the industry's first 5G integrated SOC, second generation 5G RF front-end (RFFE) program, 5G PC platform Snapdragon 8CX, Snapdragon 5G automobile platform, 5G CPE reference design, many 5G solutions, all-round surround you 5G future.
[Baseband part - 7Gbps downstream rate, Snapdragon X55 takes you tour 5G new world]
As the second-generation 5G modem of Qualcomm, the full open Snapdragon X55 5G baseband can achieve 7Gbps downlink / 3Gbps upstream rate.
As a single-chip using a 7nm process, the Snapdragon X55 supports millimeter wave and 6GHz or less, and multi-mode from 5g to 2G can also be supported. We often hear "4G All Netcom" in the 4G era, we will continue to carry forward in the Xiaolong X55.
Compared to the first X50, X55 not only has achieved performance, but also has a significant improvement in power consumption. The compatibility is better, not only beneficial to extend battery life, but also improves the performance in indoor network environment. It is expected that the terminal of the Snapdragon X55 will be listed at the end of 2019.

The flexibility of the Qualcomm platform is not only because it supports 5G and 4G dynamic spectrum sharing. Qualcomm is in the Chinese market:
China's 5G spectrum, including 2.6GHz, 3.5 GHz, 4.8 GHz, up to 100-200MHz spectrum resources per frequency section, spectrum resources are very valuable.
In the early 5G, some bands need to serve both in the 4G terminal and also serve 5G terminals. The Snapdragon X55 supports the operators to make full use of 4G and 5G spectrum sharing technology, and dynamically formulate existing 4G spectrum resources, speed 5G
Network deployment.
[RF part - winning combination, double management]
We know that in the entire communication link, we also include many devices, including radio frequency transceivers, switches, and power amplifiers (PA), including radio frequency transceivers, and an antenna. Especially in the 5G mm wave deployment, we need to support a large number of antennas on the terminal. Such a complex communication link, if used by components developed by different vendors, the integration, testing and optimization process of the entire terminal will be very long, and the cost will be very high.
In view of this, Qualcomm provides a complete suite on the RF link and completed the integration, testing and optimization of these kits in advance. Mobile phone manufacturers do not need to spend a lot of time in the terminal design, but also completing the product development, production and optimization in a short period of time, speeding up the product's listing time.
We focus on this suite in this suite here.
First, in millimeter wave, Qualcomm integrates transceivers, front and antenna arrays to the millimeter wave module, which is a new QTM525 mm wave antenna module. Qualcomm has made a lot of efforts in the size of the antenna module, providing strong support for the design of a slim 5G smartphone with a thickness of 8 mm - let the thickness of the 5G millimeter wave mobile phone, the current lightweight 4G smart machine is basically flat For other devices in your mobile phone, there is a larger space, indirectly improve the battery life.

In the 6GHz below, it has to be improved by two technologies 5G envelope trackers and 5G antenna tuning.
QET6100 5G new empty entry envelope tracker, can better manage phone signals, double the efficacy, so that longer battery life, and faster terminal data transmission.
QAT3555 5G Adaptive antenna tuning solution allows an antenna to be dynamically adapted, one of the same antennas, can cover a wider and more frequent bands.
Optimization of this can make more space for the mobile phone. Compared with the above product, its package height reduces 25%, and it has achieved longer battery life. For the challenges in the design of the battery life and body, Qualcomm also helps OEM vendors overcome difficulties through a series of solutions.
[Integrated 5G Snapdragon SOC - Let 5G go to the broader market]
The annual MWC is the most important wind direction standard in the communications industry. Qualcomm will naturally only release a big move. In fact, Qualcomm President Christiano Amon also announced Qualcomm in this year's conference launched the industry's first 5G integrated mobile platform. The so-called integrated model refers to Qualcomm to integrate 5G baseband and application processor (AP) into a SOC. This integration not only better controls the size and power consumption of the 5G chip, but also reduces 5G terminal design and Optimized, thereby supporting 5G mobile phones from the top of the pyramid to a broader consumer market.
High-norm, new integrated 5G Snapdragon SOC can support manufacturers to reuse them in the Snapdragon X50 and X55, especially in the accumulation experience in radio and radio front end, speeding up the next generation of 5G products. This product also uses 5G PowerSave technology, using C-DRX characteristics in the 3GPP specification and other high-pass "secret weapons", effectively saving power, increases the endurance capacity of 5G terminals to the current 4G mobile phone.
Mobile phones and other terminals equipped with this integrated 5G SOC are expected to be listed in the first half of next year, providing support for more than 2020 5G in more countries and regions in the world.
[Industry expansion, comprehensive coverage - 5G more than mobile phone]
For ordinary consumers, the most intuitive feelings of 5G are the improvement of mobile phone rates. However, 5G is more than one "G" is not just more than one "G" than the previous generation of 4G communication technology.
Because Qualcomm's vision is to cover the Snapdragon X55 series platform, including smartphones, mobile hotspots, Always connected PCs, tablets, notebooks, fixed wireless access points, expansion reality, and car networking. Terminal types and application scenarios.
On MWC, Qualcomm launched a variety of 5G terminal solutions, including: 1) Reference design facing 5G CPE products, connecting the Wi-Fi mesh network wireless routing in the outside of the house outside the house and Wi-Fi mesh network wireless routing into a complete solution Among the programs, such products can receive 5G signals from the outside network, but also provide Wi-Fi services to their families. 2) The industry's first commercial 5G PC platform Xiaolong 8cx, bringing 5G network to the PC product that is always online, always connected, and always supports multi-day battery life, introducing 5G into the productive environment. 3) Snapdragon Motor 5G platform, support REL-15 5G technology on the car, and provide 5G dual card dual-pass function, allowing automakers and drivers to choose different 4G / 5G network operators, this platform will Supports C-V2X communication, lane-level high-precision positioning, remote operation, etc., realizing the network vision.
4G and previous generations of wireless communication technology applications, most of them still stay in a single industry in this mobile phone. An important vision of the 5G era is to bring wireless communication technology to more industries, thereby releasing more productivity, giving birth to new business models, transforming, and even reshaping the face of many industries, so that the whole human society is comprehensive Increase.
[Conclusion]
In summary, 5G may be the same as the AI, which may be the most impact on our daily life in recent years.
Future 5G will become like electricity, becoming a basic technology, accelerating the innovation of all fields. And Qualcomm as a pioneer of 5G communication technology, has a strong appeal in the industry.
The high pass can continue to bring the customer, leading, extremely competitive full platform and solutions.
In the future, Qualcomm will continue to work together to make a huge effort to enhance customer mobile communication experience and expand technology applications.
