For many ordinary users, 802.11ac, 802.11ad, 802.11ah and other WiFi terms are too specialized. It is not easy to distinguish them. So simplifying the name is an inevitable thing. .
Now the WiFi Alliance officially announced that it will simplify the name of the corresponding technical standard, in which the new name of 802.11ax is WiFi 6, and the new name of 802.11ac is WiFi 5, and the new name of 802.11n is WiFi 4.
This change of name does not have technical adjustments. It is a simple change of name. This is also for the user to distinguish clearly. From the name point of view, the larger the number, the more advanced the technical standard is, and the faster the speed is connected.
Now that you understand this, it is good to say that the real standard for next-generation WiFi is 802.11ax. The most powerful part of this standard is that the speed of the wireless network is increased to four times that of the 802.11ac standard, and the theoretical rate that it can provide. The maximum is 1.75GB/s, which is faster than the current Gigabit fiber.
In addition, 802.11ax also supports OFDM, up to 1024QAM, and multi-user multiple input multiple output (MIMO) technology. After using the OFDA technology, the wireless bandwidth has theoretically increased by a factor of 10, but in actual tests, it can only increase by about 4 times.
