At MWC 2024, Qualcomm unveiled FastConnect 7900 modems for Wi-Fi 7 and Snapdragon X80 5G, bringing AI optimizations and greater power efficiency
Participate in the MWC 2024, the main one technology mobile of the year, the Qualcomm has expanded its portfolio of wireless networking solutions with two new features: FastConnect 7900, the first modem to unify Wi-Fi, Bluetooth and UWB processing on a single chip, and Snapdragon for the 5G Advanced era compatible with satellite communication. Both come packed with AI optimizations, responsible for not only improving signal reception, but also increasing energy efficiency.
- Snapdragon X Elite could be presented at Computex 2024
- Snapdragon 8s and 7 Plus Gen 3 could be presented in March
FastConnect 7900 combines Wi-Fi, Bluetooth and UWB
Aimed at smartphones, PCs and even extended reality (XR) glasses, the Qualcomm FastConnect 7900 is the first wireless modem to combine Wi-Fi, Bluetooth and UWB processing on a single chip. This feature would have the main advantages of reducing costs and energy consumption, since no additional processors are needed for each standard, and of reducing the space occupied in device circuits, giving more margins to manufacturers to implement other types of resources.
Another strong point of this approach is the integrated functioning of the three technologies, which would expand the recognition capabilities of proximity devices – think of smart tags like the Galaxy SmartTag from the SAMSUNGdigital car keys and communication with smartwatches and other wearable devices, and would improve some of Qualcomm’s recently announced solutions. including XPANtechnology that uses Wi-Fi and Bluetooth to deliver high-definition audio over wireless headphones, and Snapdragon Seamlessthe brand’s “ecosystem”.
The FastConnect 7900 would also be the first compatible modem the Wi-Fi 7 protocol undertake artificial intelligence optimizations, responsible for improving the quality of receiving and sending the signal, reducing latency (the delay in receiving data) and consequently increasing energy efficiency. By adding these optimizations to the new signal receiving modules (so-called RF FEMs), the reduction in energy consumption would reach 40% compared to FastConnect 7800.
Moving on to the more technical aspects, in addition to Wi-Fi 7, the new functionality operates with Bluetooth 5.4 standardbeing compatible with Bluetooth Channel Sounding, a feature that works with UWB to more accurately estimate the distance between two devices, aptX Adaptive and aptX Lossless audio codecs for high definition sound and spatial audio, aptX Voice for clearer voice calls, and LE Audio technology with broadcast to multiple devices via Auracast.
Qualcomm says that the FastConnect 7900 will “commercially debut” in the second half of 2024, which indicates that this should be the period in which we will see the first applications of the solution announced. It is very likely that we will see the modem be integrated with Snapdragon 8 Gen 4the brand’s next processor for premium smartphones which is also scheduled to launch in the second half of the year.
Snapdragon X80 supports 5G NB-NTN
Aiming at an even wider range of applications, ranging from smartphones to cars and even the Internet of Things (IoT), the Snapdragon
There are four main innovations in the solution, starting with the arrival of support for systems with up to six antennas on mobile phones, with reception managed by Artificial Intelligence. The launch also supports aggregation of up to six bands to increase speed in the sub-6GHz band and uses artificial intelligence to tailor 5G mmWave signal reception with greater efficiency, a new feature designed specifically for 5G networks FWA (Fixed Wireless Access). 5G fixed internet services sold by operators).
The earnings offered by the combination of these factors compared to the past generation attract attention: according to the giant, the FWA points would be able to increase reception by up to 60%, while mobile phones equipped with the component would be able to reduce consumption by up to 10% when using 5G mmWave. Defining the location of the device would be 30% faster, while the time to define the cell (essentially the operator’s antenna) with the best signal would decrease by 20%, resulting in 30% faster connection creation.
Perhaps the most interesting innovation is the integration of satellite communication, in the 5G NB-NTN (Narrowband Non-Terrestrial Networks) standard which, as the name suggests, this standard uses more limited bands to reduce energy consumption and guarantee the lowest latency, allowing the exchange of simple messages. While the focus is on IoT devices, we should also see phones using this feature, as Qualcomm indicates.
