802.11be (WiFi 7)

Wi-Fi 7, technically known as IEEE 802.11be, is the forthcoming wireless network standard. It builds upon the features introduced by Wi-Fi 6 and Wi-Fi 6E by substantially increasing bandwidth, supporting 320 MHz channels in the 6 GHz band. This enhancement effectively doubles the channel width compared to Wi-Fi 6/6E.

The standard incorporates 4K Quadrature Amplitude Modulation (QAM), which allows for more data to be transmitted with each signal compared to the 1K QAM of Wi-Fi 6. It also introduces Multi-Link Operation (MLO), which enables simultaneous data transmission across multiple frequencies, improving throughput, reliability, and reducing latency.
