Multi-Link Operation (MLO) is one of the most groundbreaking features in the upcoming Wi-Fi 7 (IEEE 802.11be) standard. MLO allows a Wi-Fi device to utilize multiple frequency bands simultaneously. Typically, these bands include the traditional 2.4 GHz and 5 GHz, along with the newer 6 GHz band. This simultaneous multi-band operation marks a significant evolution from previous Wi-Fi generations, which could operate on only one band at a time.

How MLO Benefits Clients

  1. Enhanced Data Throughput: By leveraging multiple bands concurrently, MLO drastically increases data throughput. This is akin to having several internet connections at once, each contributing to the overall data transfer rate.
  2. Reduced Latency: For applications demanding real-time responsiveness, such as online gaming or video conferencing, MLO’s ability to operate over multiple bands simultaneously reduces latency significantly. This improvement is crucial for an increasingly connected and instantaneous digital world.
  3. Reliability and Consistency: MLO enhances connection reliability. If one band becomes congested or suffers from interference, the system can lean more heavily on the other bands, ensuring a consistent and stable connection.
  4. Efficient Band Utilization: In environments with numerous overlapping networks, such as apartment buildings or offices, MLO allows devices to navigate crowded bands more effectively, dynamically allocating data across less congested bands.

Performance Improvement Over Wi-Fi 6

While Wi-Fi 6 introduced several improvements over its predecessors, including better handling of multiple devices and increased data rates, it was still limited to single-band operation for any given transmission. This meant that a device could only communicate over the 2.4 GHz, 5 GHz, or 6 GHz band at any one time.

MLO in Wi-Fi 7 changes this dynamic entirely by allowing devices to transmit and receive data across multiple bands simultaneously. This multi-band operation significantly elevates the performance in several ways:

  1. Higher Aggregate Speeds: The combined bandwidths of the 2.4 GHz, 5 GHz, and 6 GHz bands under MLO can offer aggregate speeds that are far beyond the capabilities of Wi-Fi 6.
  2. Greater Flexibility and Efficiency: MLO allows for more intelligent and dynamic use of the available spectrum. If one band is congested or experiencing interference, the system can automatically shift traffic to other bands, maintaining optimal performance.
  3. Improved Network Performance in Diverse Environments: Whether in densely populated urban areas or in situations with many devices competing for bandwidth, MLO ensures more robust and reliable network performance.
