Multi-Link Operation with Qualcomm FastConnect 7800 Systems

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.

Smooth casting of games

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.
