As an annual industry congress, Mobile World Congress 2022 was held in Barcelona, Spain. At this conference, in addition to seeing OPPO, Huawei, Honor and other domestic manufacturers release new mobile phones and new technologies, we also met our old friend Qualcomm and the new Snapdragon X70.
As the promoter and leader of the development of the 5G industry, Qualcomm officially opened the door to the 5G era in 2017 through the world's first 5G modem - Snapdragon X50, and this year Qualcomm baseband finally ushered in the fifth generation of 5G modems and RF systems - Snapdragon X70. Snapdragon X70 is currently the only baseband chip in the world that supports all 5G commercial frequency bands from 600MHz to 41GHz, and integrates a 5G AI processor, which is of self-evident significance to the 5G era.
1. Snapdragon X70 helps 5G application scale become more and more imaginative
The Snapdragon X70 not only has the flexibility of 5G connectivity with low latency and high coverage, but also adds AI technology support. In fact, in the fourth generation of 5G baseband chips, that is, Snapdragon X65, Qualcomm introduced AI capabilities. This time, thanks to AI technology on the Snapdragon X70, breakthrough 5G performance was achieved, including 10Gbps 5G download speed. And Snapdragon X70 also introduced Qualcomm 5G AI kit, which uses AI to optimize sub-6GHz and millimeter wave 5G links, which can more intelligently troubleshoot and predict uncertain environments, thereby optimizing millimeter wave beam focus and direction, in order to improve the stability of data transmission links, speed up data transmission rates, increase network coverage and signal strength, and extend battery life.
In addition, Snapdragon X70 also adopts AI-assisted adaptive antenna tuning technology, which is simply to introduce AI technology into the antenna tuning system, and through the analysis and learning of the antenna characteristic values of various reasons for change, the intelligent adjustment of impedance is realized to achieve the most perfect matching effect between the RF system components and the antenna. And the use of AI training models and data analysis for regulation, AI-based detection, will improve the accuracy of situational awareness, resulting in higher transmission speeds and energy efficiency and wider network coverage.
At the same time, the Snapdragon X70 supports all 5G commercial frequency bands from 600MHz to 41GHz, and supports millimeter wave independent networking. In fact, extending 5G to all spectrum types and bands has always been Qualcomm's pursuit. In addition, the Snapdragon X70 also supports spectrum aggregation functions including NR-DC and EN-DC, which simply means that a large number of spectrum resources can be aggregated to improve the efficiency and stability of transmission and connection. With the blessing of AI technology, snapdragon X70 can also better receive channel status feedback and help realize dynamic optimization for channel status.
The most obvious perception of the user may be the AI-assisted network selection. I believe that everyone has encountered the embarrassing scene that when using a mobile phone, the network switches back and forth between 5G, 4G, and 2G and cannot connect normally, especially when just entering and leaving the parking lot, elevators and other scenarios. The AI-assisted network selection on the Snapdragon X70 can intelligently identify and monitor network patterns through AI technology in a complex network environment, which can help predict and avoid certain dropped or risky connection states, thereby achieving better mobility and stability.
Another point of strong perception of users is the energy efficiency ratio of 5G, it is well known that the power consumption of 5G networks is significantly improved compared to 4G, which also causes many users to feel that the battery life performance is not good after just changing 5G mobile phones. The Snapdragon X70, which uses a 4nm baseband process, not only combines Qualcomm QET7100 broadband envelope tracker and AI technology, but also increases energy efficiency by about 60% by introducing the new 3rd generation Qualcomm 5G PowerSave, which can bring experience for further development of 5G. Of course, in addition to the above characteristics, like the Snapdragon X65, the Snapdragon X70 also supports an upgradeable architecture, which means that in the subsequent use, the Snapdragon X70 can be upgraded to obtain the new features it needs.
According to Qualcomm's official introduction, the commercial terminal equipment of Snapdragon X70 will be officially put into use later this year. 2022 as a key year for the large-scale development of 5G applications, Qualcomm bringing the Snapdragon X70 is bound to be prepared for the scale of 5G applications, which is also Qualcomm's responsibility as a promoter and leader of the development of the 5G industry.
2. Qualcomm sets a new benchmark in the field of connectivity
In addition to the Snapdragon processors and Snapdragon basebands that we are familiar with, Qualcomm's achievements in the fields of WiFi, Bluetooth and wireless audio are also leading the industry. Also at Mobile World Congress 2022, Qualcomm announced the industry's most advanced WiFi and Bluetooth connectivity system, the FastConnect 7800, which will support the latest WiFi 7 specification and support a range of advanced Features for Bluetooth audio. Here we take apart the conversation, first talk about WiFi 7.
When we are still waiting for the widespread popularization of WiFi6, WiFi 7 is coming, let's first briefly introduce to you what improvements have been made by WiFi 7 compared to WiFi 6?
First of all, WiFi 7 introduces 320MHz bandwidth, 4096-QAM, Multi-RU, multi-link operation, enhanced MU-MIMO, multi-AP collaboration and other technologies on the basis of WiFi 6, so WiFi 7 can obtain higher data transmission rates and lower latency compared to WiFi 6. WiFi7 is expected to be able to support 30Gbps throughput, which is about 3 times higher than WiFi 6.
As the world's first WiFi 7 solution, the FastConnect 7800 can use two WiFi radios at the same time to achieve high-frequency connection of four data streams in the 5GHz and 6GHz bands with high-frequency multi-connection concurrency technology. And based on this technology, the FastConnect 7800 will support all multi-connection modes, using not only the 320MHz channel in the 6GHz band, but also the 240MHz channel in the 5GHz band for an extremely low latency experience.
In recent years, applications have become increasingly demanding high throughput and low latency, such as VR, AR gaming, telecommuting, remote conferencing, and cloud classrooms. Although the current mainstream WiFi 6 network has brought an excellent experience in the use of high-density devices, it is still difficult to meet the above application scenarios that require high throughput and low latency. The emergence of the FastConnect 7800 has also released the potential of the industry to a certain extent.
In terms of Bluetooth audio, the FastConnect 7800 leverages a new generation of Smart Dual Bluetooth technology to bring hardware support for Snapdragon Sound Snapdragon Listening, Bluetooth LE Audio, and Bluetooth 5.3. Not only can it provide stable and fast connections for devices such as mice, keyboards, and gamepads, but it also increases the range of Bluetooth connections and reduces the time for Bluetooth pairing. According to Qualcomm, the FastConnect 7800 provides an immersive music experience for end devices.
When it comes to Bluetooth audio, we have to mention the two ultra-low-power wireless audio platforms launched by Qualcomm this time - Qualcomm S5 audio platform (QCC517x) and Qualcomm S3 audio platform (QCC307x). According to James Chapman, Vice President and General Manager of Qualcomm's Voice, Music and Wearables Business, "We will deliver the ultimate wireless audio experience by leveraging the Snapdragon 8 mobile platform, Qualcomm FastConnect 6900 and the newly released FastConnect 7800 connectivity system, as well as Snapdragon Sound Snapdragon listening technology." On these compact platforms, we integrate Qualcomm adaptive active noise reduction technology in dedicated hardware modules, so that no matter what the user is listening to, they can experience a substantial improvement in noise reduction.
It can be seen that Qualcomm, as a global wireless technology innovator, has its own unique solutions for connection technology. The basic technology and professional technology brought by Qualcomm have played a key guiding role in solving the user connection experience, wireless connection quality, and promoting digital transformation. Qualcomm also based on its own understanding of wireless connectivity, bringing a new Snapdragon Connect brand logo.
3. Qualcomm "connected" everything
The Internet of Everything is the general trend of the 5G era, but the terminal devices we are currently exposed to are not really the "connection" of all things. Whether it is smart devices such as mobile phones, watches, computers, or traditional terminals such as TVs and cars, the biggest problem that plagues their interconnection is in this "connection". The current cellular data and WiFi cannot meet the rapid response and connection between terminals.
On devices with the new Snapdragon Connect brand identity, they will be equipped with top Snapdragon 5G, Wi-Fi and Bluetooth technologies, whether it is mobile phones, computers, TVs, cars, Snapdragon Connect terminals can bring smooth download and upload speeds and fast response experiences. And with the best Snapdragon connection technology, greatly reducing the latency between terminals, so VR and AR devices with the new Snapdragon Connect brand logo can bring a closer to the real experience, while with the new Snapdragon Connect brand logo of Bluetooth audio devices, you can bring a more immersive experience to your virtual world.
Not only that, since we want to achieve the true sense of "Internet of Everything", then in the complex environment of dense crowds and in the suburbs far from the people, it must also be able to connect freely. Snapdragon Connect terminals also provide technical support and support in these relatively "extreme" scenarios.
Of course, when enjoying a stable connection experience, it will inevitably bring about an increase in energy consumption. Based on this problem, the Snapdragon computing platform adopts a unique system-level approach to build, integrating key connection components in a complete energy-saving design, which is enough to ensure that the terminal can provide strong support for the aspect of battery life while bringing smooth interconnection.
Snapdragon Connect seems like a complicated thing, but it is also an inevitable trend in the development of mobile platforms in the 5G era. Combined with the previous development trajectory of Qualcomm and the new products and technologies released by the Mobile World Congress, the emergence of Snapdragon Connect is traceable.
A few brief chats
For users, the emergence of Snapdragon Connect is infinitely beneficial. This not only means that we can experience a smooth interconnection experience, but also means that the intelligent society of the Internet of Everything is getting closer and closer to us; for terminal manufacturers, the emergence of Snapdragon Connect can "empower" the terminal from the underlying technology to help the terminal enter the interconnected system; for Qualcomm, Snapdragon Connect is not only Qualcomm's "solution" to the Internet of Everything, but also through its own top technology. Moving the entire industry in the right direction.
Although Qualcomm has not yet announced when the Snapdragon Connect terminal will be officially launched, Snapdragon Connect is not far from us in terms of Qualcomm's release of Snapdragon X70, FastConnect 7800, Qualcomm S5, S3 audio platform and other products. It is foreseeable that Qualcomm will surely become an important piece of the puzzle in the interconnected world in the future. For users, if they want to experience a smooth interconnection experience in the future, there will be no mistake in looking for snapdragon Connect terminals.
