According to Qualcomm, Wi-Fi 7 will double the bandwidth and speed of Wi-Fi 6 while cutting latency in half. In addition, it will have many new features that will make it special.

Wi-Fi 7 will double the maximum channel width (up to 320 MHz) and introduce higher order modulation with 4kQAM. In addition, Wi-Fi 7 will have another key feature - the ability to manage and, therefore, optimize the various available spectrum bands. This function will be called multi-link operation (MLO). MLO allows devices to use spectrum on multiple channels at the same time.

The highest performance [for Wi-Fi 7 MLO] is simultaneous multi-channel communication in the high frequency range. The device uses each lane as it becomes available and can run on both at the same time, aggregating bandwidth across both. Because it can operate simultaneously on each band, it is even better at preventing congestion and reducing latency.

MLO boasts several useful features. Let's say it not only aggregates channels from different ranges, but also establishes a connection between several devices in the same range. For example, if the Network does not support the 6 GHz distribution, they can still enjoy 320 MHz Wi-Fi channel speeds (two 160 MHz channels). Among the regions suffering from the lack of 6 GHz spectrum, China should be noted. Moreover, this country does not plan to follow this path. But with Wi-Fi 7 and MLO, providers can set up a 240 MHz channel in the 5 GHz band.

Finally, Wi-Fi 7 will support preamble puncturing, which allows a Wi-Fi network to "cut" and avoid using the part of the spectrum containing interfering signals.
