Wi-Fi 7 Explained: 320 MHz Channels and Multi-Link Operation

What Wi-Fi 7 is

The Wi-Fi Alliance, which certifies Wi-Fi products, says Wi-Fi CERTIFIED 7 was introduced in 2024. It enhances performance across the 2.4 GHz, 5 GHz and 6 GHz bands, delivering high throughput, lower latency and greater reliability for demanding uses such as AR/VR/XR, immersive 3D training and ultra-high-definition video streaming.

Key features it lists

  • 320 MHz channels in the 6 GHz band: these provide twice the throughput of Wi-Fi 6, enabling multigigabit Wi-Fi device speeds.
  • Multi-link operation: supports more efficient load balancing of traffic among links, increasing throughput and reliability.
  • 4K QAM: a modulation feature the Alliance lists among its capabilities.

The Alliance says these features help devices perform in homes, enterprise and industrial environments, even in dense venues like stadiums and large campuses.

What this means for buyers

  • Both your router and your device must support Wi-Fi 7 to use these features.
  • The 6 GHz band is needed for the 320 MHz channels. Whether it is available depends on local regulation, which we have not checked for Sri Lanka.
  • Your internet plan's speed is a separate limit. A faster Wi-Fi standard does not raise the speed of the connection you buy from your provider.

The Alliance's figures are best-case capabilities. We have not benchmarked any product, so we make no speed promises.
