Recently, the latest revision of the 802.
11ac protocol 802.
11ax standard was introduced, compared with the 802.
11ac standard, 802.
11ax can be said to be the inheritance and development version of the former, both use the 5GHz frequency band and support MU-MIMO technology, but in the 802.
11ac standard, MU-MIMO is "optional", currently only used on the flagship product of "802.
11ac Wave 2"; In the 802.
11ax standard, MU-MIMO is "standard", and the first release will directly provide support
.
Another very important innovation of 802.
11ax is the introduction of OFDMA (Orthogonal Frequency Division Multiple Access) orthogonal frequency division multiple access technology, which is used in WiMax and LTE and is known as the core technology
of the next generation of wireless networks.
OFDMA technology can divide a conventional channel into several or even dozens of orthogonal sub-channels, and greatly improve the efficiency
of data transmission by superimposing and assigning these sub-channels to different users.
Compared with the OFDM (Orthogonal Frequency Division Multiplexing) orthogonal frequency multiplexing technology used in 802.
11ac, OFDMA technology can theoretically bring 10 times more improvement in data transmission efficiency, even if the interference and loss, modulation and demodulation rate and other factors are considered, the efficiency of OFDMA is 4 to 5 times
that of OFDM technology.
In fact, the primary goal of the 802.
11ax standard is to increase the rate of wireless networks to 4 times of the 802.
11ac standard, currently in the 5GHz band and 80MHz bandwidth, the theoretical rate of 802.
11ac single stream is 433Mbps, according to this calculation, 802.
11ax under the same conditions of single stream rate is as high as 1733MHz, if you add 4x4 MU-MIMO technology and 160MHz bandwidth addition, The theoretical rate that the 802.
11ax standard can provide will reach 14Gbps, equivalent to 1.
75GB/s, directly killing the current "gigabit fiber"
