Multi-Link Operation (MLO) in Wi-Fi 7

Wi-Fi 7's Multi-Link Operation (MLO) is a game-changing feature that's set to revolutionize wireless connectivity. As a network engineer, I'm particularly excited about its potential to optimize bandwidth usage and enhance connection reliability.

At its core, MLO allows devices to simultaneously transmit and receive data across multiple frequency bands (2.4 GHz, 5 GHz, and 6 GHz). This is a significant leap from previous Wi-Fi generations, where devices were limited to a single band connection at a time.

The key pros of MLO are:

• Increased throughput: By aggregating bandwidth across multiple channels, we're looking at theoretical speeds up to 30 Gbps;
• Reduced latency: MLO can achieve sub-1ms latency in ideal conditions, rivaling wired connections;
• Improved reliability: The ability to dynamically switch between links ensures a more stable connection.

MLO operates in two primary modes:

1. STR (Simultaneous Transmit and Receive): Links work independently without interference;
2. NSTR (Non-simultaneous Transmit and Receive): All links either transmit or receive simultaneously.

On a technical level, MLO implements packet-level and flow-level aggregation. This allows for optimized routing and improved overall performance.

To leverage MLO, both the client device and the access point need to support Wi-Fi 7. While the 6 GHz band isn't mandatory for MLO, its inclusion can significantly boost performance.

In practical terms, MLO opens up possibilities for bandwidth-intensive applications like 8K streaming, AR/VR, and cloud gaming, while also enhancing the reliability of critical applications in enterprise and industrial settings.

What is Multi-Link Operation (MLO) in Wi-Fi 7

Multi-Link Operation in Wi-Fi 7 represents a significant leap forward in wireless networking technology. By allowing devices to simultaneously use multiple frequency bands, MLO dramatically improves speed, reduces latency, and enhances reliability.

This feature paves the way for more robust and efficient wireless connections, capable of supporting increasingly demanding applications like AR/VR, cloud gaming, and 8K streaming. As we move towards a more connected future, MLO stands out as a key innovation that will reshape our expectations of wireless performance and reliability.
