Multi-Link Operation (MLO) in WiFi 7
Elite gamers and productivity specialists who are always on the run value every second. Qualcomm Technologies, Inc. revolutionized multi-device mobile experiences with the Qualcomm FastConnect 7800 and Qualcomm FastConnect 7900 Mobile Connectivity Systems. It would be wonderful to quickly switch between mobile and desktop game play and workflow.
Multi-Link Operation (MLO), which enables numerous connections to a device, is a fundamental feature of Wi-Fi 7. High Band Simultaneous (HBS) Multi-Link, which enables the simultaneous use of two 5 and/or 6 GHz bands for the maximum throughput and lowest latency currently achievable, is one of the forms of MLO that Qualcomm Technologies implemented.
FastConnect 7800 This strong and adaptable connectivity solution, called FastConnect 7800, combines premium Wi-Fi 6/6E, cutting-edge Bluetooth audio, and the industry’s top Wi-Fi 7 to unleash unprecedented performance for mobile, compute, and XR experiences. With its cutting-edge 14nm Wi-Fi and Bluetooth connectivity system, the Qualcomm FastConnect 7800 Mobile Connectivity System offers excellent Bluetooth audio, ultra-high speeds (up to 5.8 Gbps), and sustained low latency (2 ms). With its advanced innovation, FastConnect 7800 surpasses standard benchmarks and complies with the most recent Wi-Fi 6/6E and Wi-Fi 7 standards. High Band Simultaneous Multi-Link Wi-Fi technology does away with reliance on the relatively limited and crowded 2.4GHz band by utilizing the possibilities of the 5 and 6GHz bands. FastConnect 7800 further enhances Bluetooth LE Audio, Snapdragon Sound Technology, and Bluetooth 5.4 with next-generation Dual Bluetooth two streams, which doubles the range of Bluetooth accessories and simplifies the process of switching from a smartphone to a PC or earbuds to an automobile’s hand-free system. With 5 and 6GHz connections, multi-gigabit performance WiFi can reach peak speeds of up to 5.8 Gbps; in the event that 6GHz is not available. Extremely Low Latency
With the next-generation Qualcomm 4-stream DBS, you may enjoy jitter-free experiences and 2 ms latency with high band simultaneous technology for multi-link operation of 5 and/or 6GHz performance applied across standards, or for a premium Wi-Fi 7 experience when linked with compatible AP.
Flexibility Either linked to widely accessible Wi-Fi 6 or 6E infrastructure or cutting-edge Wi-Fi 7 access points, and situated in an area with or without 6GHz connectivity, Fast Connect 7800 offers advanced High Band Simultaneous deployments to meet immediate needs.
Snapdragon Sound & Bluetooth Audio The delivery of Snapdragon Sound, LE Audio, and Bluetooth 5.4 to audio devices is greatly improved by Next-generation Dual Bluetooth, which provides two simultaneous audio streams. Go twice as far and listen for longer while saving 30–50% on electricity.
Features Constructed for Wi-Fi Certification 7 Support for 5GHz, 2.4GHz, and 6GHz 320MHz channel bandwidth and 4K QAM modulation allow for a data rate of up to 5.8 Gbps(single channel or 160 + 160 with High Band Simultaneous). Up to 4.3 Gbps employing multi-link operation streams of globally available 5GHz spectrum, along with 240MHz channel capacity and 4K QAM. Using next-generation standards, unique high band simultaneous technology provides multiple lines with 5 and/or 6GHz performance. Supported by Qualcomm 4-stream DBS When used with an AP that is compatible, Wi-Fi 7 High Band Simultaneous Multi-link Premium Wi-Fi 7 is available. Extended wireless audio sessions with power savings of 30-50% Support for ANT+, Bluetooth 5.4, and LE Audio Advanced Dual Bluetooth functionality aimed at providing simultaneous audio streams for dependable long-range connections Encourages Supported by Qualcomm FastConnect Software Suite for XR Snapdragon Sound Technology LE Audio allows users to broadcast and share their own music, allowing them to join or share streams with others.

The rise in high-quality, bandwidth-intensive data and applications has increased the need for HBS. Game-casting, the common use case where a mobile phone or handheld is used to cast content to a smart TV, is one where HBS would be quite valuable. When a gamer uses HBS to game-cast, they may play on a bigger screen with Qualcomm fastconnectivity instead of experiencing latency from the crowded 2.4GHz band or a delay from switching between the 5GHz and 6GHz bands.
Close enough for a longer show The integration of HBS and a wide range of proximity technologies, including as Wi-Fi ranging, Bluetooth Channel Sounding, and Ultra Wideband (UWB), elevates seamless experiences with FastConnect 7900. By incorporating proximity technologies, devices may sense other devices in their immediate vicinity and interact with them more naturally all without the user having to take active control.
The expanded display use case is one illustration of how proximity technologies and HBS work in perfect harmony with one another. A laptop user can use a tablet as an additional screen, as demonstrated above. Here, UWB is used to identify the tablet’s presence as well as its orientation, while HBS uses fast 5GHz or 6GHz connections to link the laptop, tablet, and access point all at once.
Superior sound quality with XPAN Audio is a further developing use case where proximity and HBS together can show to be revolutionary. Because many of the major streaming providers support lossless audio, there is an increasing demand for high-quality lossless music. Audiophiles can benefit from Expanded Personal Area Network (XPAN) technology in their headphones or earbuds with our recently announced Qualcomm S7 Pro Gen 1 Sound Platform.
This innovative technology combines XPAN and micro-powered Wi-Fi to provide a more reliable connection with reduced latency, increased throughput, and increased coverage. All connections are in the high-speed bands when HBS is used, guaranteeing that the listener receives the highest-quality audio possible from the streaming services they pay for.
