Qualcomm's Wireless Triad: Snapdragon X70, Wi-Fi 7, M.2 5G Module

Click on the top Computer Enthusiasts to follow us

At MWC 2022, Qualcomm unveiled the new generation of “Wireless Triad”, consisting of the world’s only full-band, first AI-integrated 5G modem Snapdragon X70 with speeds up to 10Gbps; the world’s first Wi-Fi 7 FastConnect 7800 mobile connectivity system; and the Snapdragon M.2 5G module with internet speeds of up to 10Gbps, setting a new benchmark for wireless experiences.

Snapdragon X70 Modem

The current modem integrated into the new Snapdragon 8 is the Snapdragon X65 modem, which is the world’s first to achieve a download speed of 10Gbps and supports fourth-generation 5G millimeter-wave technology.

Snapdragon X70 is the successor to Snapdragon X65 and will be the best partner for the Snapdragon 8 Gen2, representing the strongest 5G performance in the mobile phone field.

Snapdragon X70 is Qualcomm’s fifth-generation 5G modem solution and the only one in the world that supports all commercial 5G frequency bands from 600MHz to 41GHz, as well as the first modem chip to integrate a 5G AI processor. This AI processor brings the following improvements:

－ AI-assisted channel state feedback and dynamic optimization to enhance throughput and other key performance metrics.

－ The world’s first AI-assisted millimeter-wave beam management to enhance performance, increase throughput, expand cell coverage, and improve link robustness.

－ AI-assisted network selection, supporting excellent mobility and link robustness.

－ AI-assisted adaptive antenna tuning, improving situational awareness by 30%, achieving higher average speeds and broader network coverage.

The peak downlink speed of Snapdragon X70 remains 10Gbps, with a peak uplink speed of 3.5Gbps, supporting all commercial 5G frequency bands, millimeter-wave standalone networking, global multi-SIM (including dual-SIM dual-active), spectrum aggregation (NR-DC/EN-DC), upgradable architecture, third-generation PowerSave technology, AI-assisted adaptive antenna tuning, QET7100 broadband envelope tracking, and more.

In short, the biggest feature of Snapdragon X70 is its ability to use Qualcomm’s 5G AI suite to optimize 5G links in the Sub-6GHz and millimeter-wave bands, enhancing speed, network coverage, mobility, link robustness, energy efficiency, and reducing latency.

FastConnect 7800

The current mobile connectivity system integrated into the new Snapdragon 8 is the FastConnect 6900, which achieves downlink speeds of up to 3.6Gbps for Wi-Fi 6/6E. This platform also supports Bluetooth 5.2 and Snapdragon Sound technology, and for the first time supports the new LE Audio, including broadcast audio, stereo audio recording, and game voice synchronization.

As its successor, the FastConnect 7800 mobile connectivity system will theoretically also partner with Snapdragon 8 Gen2. It is the world’s first commercial Wi-Fi 7 solution, fully supporting all features of Wi-Fi 7 and is currently the fastest and lowest-latency Wi-Fi product.

The theoretical peak transmission speed of FastConnect 7800 can reach 5.8Gbps, an increase of up to 60% compared to its predecessor, but to achieve this speed, the 6GHz band, 320MHz channel, or paired 160MHz channels must be used. In areas where the 6GHz band is unavailable, the 5GHz band can only combine the 160MHz and 80MHz channels into a 240MHz bandwidth, resulting in a theoretical maximum speed of 4.3Gbps, still faster than FastConnect 6900’s 3.9Gbps.

FastConnect 7800 also supports the latest Bluetooth 5.3, dual Bluetooth (2×2), LE Audio, ANT+, and Snapdragon Sound technology, supporting 16-bit 44.1kHz CD-quality lossless Bluetooth audio, 24-bit 96kHz ultra-high-definition Bluetooth audio, 32kHz ultra-wideband voice calls, 68ms audio delay gaming mode, seamless gaming experience, in-game voice chat, stereo recording, and robust connections in complex congested RF environments.

Snapdragon M.2 5G Module

As mobile computing terminals, smartphones and tablets have entered the 5G era, laptops cannot lag too far behind. Qualcomm’s newly released Snapdragon M.2 5G module is a type of network card that helps laptops, all-in-ones, and traditional PCs connect to 5G networks anytime, anywhere.

The Snapdragon M.2 5G module integrates the Snapdragon X65 or Snapdragon X62 5G modem and RF system, being the world’s first extension module supporting 10Gbps 5G speeds and 3GPP R16 specifications, supporting Sub 6G and millimeter-wave, with the richest support for 5G bands and spectrum currently available.

However, the popularization of the Snapdragon M.2 5G module is not an easy road.

All-in-ones and desktops used in fixed locations already have the most stable wired network connections and have little need for 5G wireless. Although laptops have a strong demand for 5G, 99% of the lightweight laptops on the market only come with 2 M.2 slots, one for installing the wireless network card and one for installing the SSD, leaving no space to install the M.2 5G network card.

Although gaming laptops generally reserve an extra M.2 slot, its main purpose is also to install SSDs. Even if the M.2 5G network card can be installed, there are no reserved antennas or related antenna paths.

Therefore, the Snapdragon M.2 5G module is currently only the patent of a few high-end business laptops, and consumer-grade laptops will not experience it in the short term. Unless Qualcomm can later launch an M.2 module that integrates 5G and Wi-Fi, or the majority of laptops begin to come standard with additional M.2 slots specifically customized for 5G modules.
