Qualcomm FastConnect 7800 Systems: Multi-Link Operation

 WiFi 7's Multi-Link Operation (MLO)

Elite gamers and productivity specialists who are always on the run value every second. The Qualcomm FastConnect 7800 and Qualcomm FastConnect 7900 Mobile Connectivity Systems from Qualcomm Technologies, Inc. completely changed the way people interacted with mobile devices. The ability to seamlessly transition between desktop and mobile game play and workflow would be fantastic.


A key component of Wi-Fi 7 is Multi-Link Operation (MLO), which allows several connections to a single device. Qualcomm Technologies introduced two types of MLO: High Band Simultaneous (HBS) Multi-Link, which allows two 5 and/or 6 GHz bands to be used simultaneously for the largest throughput and lowest latency currently attainable.

RapidConnect 7800

FastConnect 7800 is a robust and versatile connection solution that unleashes exceptional performance for mobile, compute, and XR experiences. It combines premium Wi-Fi 6/6E, state-of-the-art Bluetooth audio, and the industry's best Wi-Fi 7.
The Qualcomm FastConnect 7800 Mobile Connectivity System boasts a state-of-the-art 14nm Wi-Fi and Bluetooth connectivity system that provides exceptional Bluetooth audio quality, ultra-high speeds (up to 5.8 Gbps), and sustained low latency (2 ms).
FastConnect 7800 exceeds industry requirements and conforms to the latest Wi-Fi 6/6E and Wi-Fi 7 standards thanks to its cutting-edge innovation. High channel Simultaneous Multi-Link Wi-Fi technology leverages the capabilities of the 5 and 6GHz bands to eliminate dependence on the comparatively constrained and congested 2.4GHz channel.
With next-generation Dual Bluetooth two streams, FastConnect 7800 improves Bluetooth LE Audio, Snapdragon Sound Technology, and Bluetooth 5.4 even further. This feature doubles the range of Bluetooth accessories and makes it easier to switch from a smartphone to a PC or earbuds to an automobile's hand-free system.
In the event that 6GHz is unavailable, multi-gigabit performance WiFi can achieve peak rates of up to 5.8 Gbps with 5 and 6GHz connections.

Exceptionally Low Latency

With the next-generation Qualcomm 4-stream DBS, you can take advantage of high band simultaneous technology for multi-link operation of 5 and/or 6GHz performance applied across standards, jitter-free experiences, and 2 ms latency. When coupled with a compatible AP, you can also enjoy premium Wi-Fi 7.

Adaptability

Fast Connect 7800 provides enhanced High Band Simultaneous deployments to address immediate needs, whether it is located in an area with or without 6GHz connectivity, and is connected to widely accessible Wi-Fi 6 or 6E infrastructure or state-of-the-art Wi-Fi 7 access points.

Bluetooth Audio & Snapdragon Sound

Next-generation Dual Bluetooth, which offers two simultaneous audio streams, significantly improves the delivery of Snapdragon Sound, LE Audio, and Bluetooth 5.4 to audio devices. Save 30 to 50% on electricity and listen for longer while travelling twice as far.

seamless game casting

HBS is becoming more and more necessary as high-quality, bandwidth-intensive data and applications proliferate. HBS would be very helpful in the popular use case of "game-casting," which is the casting of material from a mobile phone or handheld device to a smart TV. Gamers may play on a larger screen with Qualcomm fastconnectivity when they utilise HBS to game-cast, as opposed to being delayed by busy 2.4GHz or 5GHz–6GHz band switching.

Near enough to warrant a longer run

Seamless experiences with FastConnect 7900 are elevated by the integration of HBS with a variety of proximity technologies, such as Wi-Fi ranging, Bluetooth Channel Sounding, and Ultra Wideband (UWB). Through the use of proximity technologies, devices may recognise and communicate with other devices more naturally, all without requiring the user to take active control.

One example of how proximity technologies and HBS complement each other perfectly is the extended display use case. As seen above, a laptop user can utilise a tablet as an extra screen. Here, HBS links the laptop, tablet, and access point simultaneously using fast 5GHz or 6GHz connections, while UWB detects the tablet's existence and position.


An additional emerging use case where proximity and HBS combined potentially prove to be revolutionary is superior sound quality using XPAN Audio. There is a growing market for excellent lossless music as many of the main streaming services offer it. With the recently released Qualcomm S7 Pro Gen 1 Sound Platform, audiophiles may take advantage of Expanded Personal Area Network (XPAN) technology in their headphones or earbuds.

By combining XPAN and micro-powered Wi-Fi, this cutting-edge technology offers a more dependable connection with lower latency, more throughput, and wider coverage. When HBS is utilised, all connections are in the high-speed bands, ensuring that the listener gets the best audio quality from the streaming services they pay for.
