Wi-Fi 7 is starting to emerge: speeds up to 30Gbits per second

Wi-Fi 6 is just beginning to become popular, and scientists have already begun to promote Wi-Fi 7.

According to the information disclosed so far, Wi-Fi 7 has a speed of up to 30Gbits per second, which can provide better streaming video, cover longer distances, and reduce congestion. The Wi-Fi Alliance has not yet widely promoted this new standard.

It’s important to note that the three newest Wi-Fi standards: IEEE 802.11n, 802.11ac, and 802.11ax, are certified as Wi-Fi 4, 5, and 6, respectively. Therefore, 802.11be is a strong candidate to receive the Wi-Fi 7 label.

As 5G network commercialization accelerates, Wi-Fi 6 (IEEE 802.11ax) will become more and more popular and is expected to replace the existing Wi-Fi standard around 2023. It is understood that Wi-Fi 6 can use multiple RF bands from 1GHz to 7GHz, including the 2.4GHz and 5GHz bands currently used by Wi-Fi, and its transmission speed is 3-4 times faster than the Wi-Fi 5 standard (IEEE 802.11ac).

In addition, Wi-Fi 6 also supports OFDM, up to 1024QAM, and multi-user multiple input multiple output (MIMO) technology. After using OFDA technology, the wireless bandwidth has increased by 10 times in theory, but in actual tests, it can only increase by about 4 times.
