MWC 2019:5G Strategic Analysis of the Invasion of Qualcomm X55 Chip

via:cnBeta.COM     time:2019/3/4 14:12:09     readed:315

While providing support for the next generation of 5G mobile phones, this new platform can also bring advanced 5G connectivity to many forms of terminal devices such as PC, automobile and so on. In fact, the X55 is not Qualcomm's only big move on the MWC. Qualcomm has also launched the industry's first 5G integrated SoC, the second generation 5G radio frequency front end (RFFE) solution, 5G PC platform Yuelong 8cx, Yuelong 5G automobile platform, 5G CPE reference design and many other 5G solutions, enclosing your 5G future in an all-round way.

As the second generation 5G modem of Qualcomm, the full-fired MX555G baseband can achieve 7Gbps downlink/3Gbps upstream rate.

As a single chip with 7Nm process, MX55 supports millimeter wave and frequency band below 6GHz, and also supports multimode mode mode from 5G to 2G. We often hear about "4G All Netcom" in the era of 4G, and continue to develop on the X55.

Qualcomm platform is not only flexible, because it also supports 5G and 4G dynamic spectrum sharing. Qualcomm cites the Chinese market as an example:

China's 5G spectrum, including 2.6 GHz, 3.5 GHz, 4.8 GHz, each band up to 100-200 MHz spectrum resources, spectrum resources are very valuable.

At the beginning of 5G, some bands need to serve both 4G terminals and 5G terminals. Through the spectrum sharing technology of 4G and 5G, MX55 supports operators to make full use of and dynamically allocate existing 4G spectrum resources, thus speeding up 5G.

Network deployment.

[Radio Frequency Part - Winning Combination, Two-pronged Operation]

We know that in the whole communication link, besides the modem, there are also many devices, including RF transceivers and filters, switches and power amplifiers (PA) and other RF front-end, including antennas. Especially in 5G millimeter wave deployment, we need to support a large number of antennas on the terminal. Such a complex communication link, if used by different vendorsDevelopmentThe integration, testing and optimization process of the whole terminal will be very long and the cost will be very high.

In view of this, Qualcomm provides complete suites on the RF link, and completes the integration, testing and optimization of these suites in advance. Mobile phone manufacturers do not need to spend a lot of time on terminal design, but also can complete product development, production and Optimization in a relatively short time to speed up the time of product launch.

Here we will focus on several core products in this suite.

Firstly, in millimeter wave, Qualcomm integrates transceiver, front-end and antenna array into millimeter wave module, which is a brand new QTM525 millimeter wave antenna module. Qualcomm has made a lot of efforts on the size of antenna module, which provides a strong support for the design of thin 5G smartphones with thickness less than 8mm. The thickness of 5G millimeter-wave smartphones is basically the same as the current lightweight 4G smartphones. It also provides more space for other devices and batteries in mobile phones to indirectly improve the endurance.



In the frequency band below 6GHz, it is necessary to improve the tuning of 5G envelope tracker and 5G antenna, two technologies which are proud of.

QAT3555 5G adaptive antenna tuning solution can make the antenna dynamic and adaptable. A same antenna can cover a wider and wider band.

This optimization can make more room for mobile phones. Compared with the previous generation products, the packaging height is reduced by 25%, and the battery life is longer. Qualcomm has also helped OEM manufacturers overcome difficulties through a series of solutions to the problems of endurance and fuselage design.

The integrated 5G SoC mobile phone and other terminals are expected to be launched in the first half of next year, providing support for the wider popularization of 5G in more countries and regions around the world by 2020.

[Industry Expansion, Full Coverage - 5G is More than Mobile Phone]

For ordinary consumers, the most intuitive feeling of 5G is the increase of mobile phone speed. But compared with the previous generation of 4G communication technology, 5G is not only as simple as one more "G".

Because Qualcomm's vision is to use the X55 Series platform of Miaolong to cover all kinds of terminal types and application scenarios, including smartphones, mobile hotspots, PC, tablet computers, notebooks, fixed wireless access points, extended reality, and vehicle networking.

On MWC, Qualcomm has launched a number of 5G terminal solutions, including: 1) Reference design for 5G CPE products, which integrates CPE for outdoor 5G base stations and Wi-Fi wireless routing for indoor network into a complete solution, so that such products can receive 5G signals from the outside network and provide Wi-Fi services to families. 2) The industry's first commercial 5G PC platform, Yulong 8cx, brings 5G network to PC products that are always online and interconnected, and always supports battery life for days, and introduces 5G into the productive environment. 3) The 5G platform of Qiulong Automobile supports Rel-155G technology on the automobile, and provides 5G dual-card dual-pass function, which allows automobile manufacturers and drivers to choose different services of 4G/5G network operators. This platform will support frontier applications such as C-V2X communication, lane-level high-precision positioning, remote operation, and realize the vision of vehicle networking.

Most of the applications of 4G and previous generations of wireless communication technology remain in the single industry of mobile phones. An important vision of the 5G era is to expand wireless communication technology to more industries, thereby releasing more productivity, promoting new business models, transforming and even reshaping the face of many industries, so that the entire human society can be fully upgraded.


To sum up, perhaps 5G and AI, may be in recent years in our daily life have the biggest impact on technology.

In the future, 5G will become like electricity, a basic technology, accelerating entrepreneurship innovation in all fields. Qualcomm, as the pioneer of 5G communication technology, has a strong appeal in the industry.

Focusing on the MX555G baseband and the second generation RF front-end solutions, Qualcomm can continue to provide customers with industry-leading, highly competitive and complete platforms and solutions.

In the future, Qualcomm will continue to work with partners from all walks of life to make tremendous efforts to enhance customer mobile communication experience and expand the application scope of technology.
