On March 1 day, Qualcomm released four heavy new products and related technologies at Barcelona MWC last night, including Snapdragon X70 modem and RF system, Wi-Fi and Bluetooth connection system FastConnect 7800, as well as Qualcomm S5 audio platform (QCC5 17x) and Qualcomm S3 audio platform (QCC307x).

Snapdragon X70 5G modem and RF system is the world's first 5G AI processor, while FastConnect 7800 is the world's first Wi-Fi 7 solution. Two audio platforms support CD-quality lossless audio and headphone stereo recording, and the game delay is reduced by 25%.

Thanks to Qualcomm's 5G AI suite, Snapdragon X70 has added many new functions, including AI-assisted channel state feedback and dynamic optimization, the world's first AI-assisted millimeter-wave beam management, AI-assisted network selection and AI-assisted adaptive antenna tuning.

Snapdragon X70 supports 10Gbps 5G peak download speed, and is equipped with Qualcomm 5G AI suite, Qualcomm 5G ultra-low latency suite and four carrier aggregation. Qualcomm's 5G ultra-low latency suite in Snapdragon X70 supports terminal manufacturers and operators to minimize latency.

At the same time, Snapdragon X70 introduces the third generation Qualcomm 5G PowerSave technology, and combines the 4nm baseband technology, Qualcomm QET7 100 broadband envelope tracking technology and AI-assisted adaptive antenna tuning technology, which can dynamically optimize the transmission and reception paths under various user scenarios and signal conditions, thus reducing power consumption and prolonging battery life.

Qualcomm announced that Snapdragon X70 is expected to start providing samples to customers in the second half of 2022, and commercial mobile terminals are expected to be launched later in 2022.

High-frequency multi-connection concurrency technology is the iconic Wi-Fi 7 feature in the FastConnect 7800 mobile connection system, which can realize high-frequency connection of four data streams in 5GHz and/or 6GHz bands by using two Wi-Fi radio frequencies at the same time.

Based on high-frequency multi-connection concurrency technology, FastConnect 7800 supports all multi-connection modes, and users can experience the lowest delay and interference by using the 320MHz channel in the increasingly popular 6GHz band or the 240MHz channel in the globally available 5GHz band.

In Qualcomm's view, expanding 4-channel dual-frequency concurrency (DBS) to high frequency band can realize direct benefits in today's network. Based on the well-known dual-frequency (2 2+2 2) characteristics of Qualcomm 4, the high-frequency multi-connection concurrency technology can be used cooperatively between access points and clients, or can be used independently in multi-client scenarios through 5GHz and/or 6GHzWi-Fi connections to achieve extremely low delay performance.

In addition, with the new generation of intelligent dual Bluetooth technology, that is, two radio frequencies with optimized connection, FastConnect 7800 provides good support for Snapdragon listening technology, Bluetooth LE audio and Bluetooth 5.3, which increases the signal connection range of Bluetooth accessories by nearly 1 time and shortens the pairing time by half.

With FastConnect 7800, Bluetooth terminal devices can transmit high-bandwidth immersive music by using Snapdragon listening technology, and at the same time provide a powerful and fast response connection for gamepads and/or other input devices.

The two ultra-low power wireless audio platforms released by Qualcomm this time-Qualcomm S5 audio platform (QCC5 17x) and Qualcomm S3 audio platform (QCC307x) both support Snapdragon Sound Snapdragon listening technology. These two platforms are optimized to support dual Bluetooth mode, combining the traditional Bluetooth wireless audio with the new LE audio technical standard.

These two new platforms provide audio OEMs with better flexibility and support them to customize multiple levels of products. Audio devices using these two new platforms can support more functions, including Snapdragon listening technology of Snapdragon sound, CD-level lossless Bluetooth sound quality of 16-bit 44. 1kHz, ultra-clear call support of 32kHz ultra-wideband voice and so on.

In addition, the two platforms can bring stereo recording function to the creators, so that the recorded content has stereo effect. At the same time, even in the complex RF environment, the two platforms can obtain stable connection. In the game mode, the audio delay is as low as 68ms, which supports synchronous voice return.

At present, Qualcomm S5 audio platform (QCC5 17x) and Qualcomm S3 audio platform (QCC307x) are being sampled to customers, and they are expected to be commercialized in the second half of 2022.
