802.11ax 6 th generation WiFi


802.11ax called the 6 th generation WiFi is another version of the wireless network standard. It was designed in a way that it can effortlessly serve a bigger number of devices through one access point at higher speeds. The standard uses the techniques provided by its predecessors such as 802.11ac or n. 802.11ax was mainly designed to operate in the 5GHz band. Higher transmission speeds theoretically reaching 14Gb/s and practical approximately 6Gb/s can be achieved thanks to using modern IT technologies. Among the most important changes are:

  • using the OFDMA modulation which is the temporary frequency modulation or the transmission channel is not only divided in time between several users but it is also split into various frequency sub-channels. As a result the access point transmits data to various recipients which was impossible in the previous versions of the wireless network standard. The 802.11ac standard and all the previous ones only enabled the transmission to one terminal point in a certain unit of time. The above procedure significantly improves the transmission quality especially in the environments with big number of receivers that have to fight for the access to one point.
  • MU-MIMO – using a few transmission and reception antennas in one access device enabled transmitting a few data streams to one receiver. The above functionality was available in the previous version of the standard only for the downlink transmission or from the access point of the terminal device. Currently these devices can also create more data streams using a few antennas in order to send the signal from the receiver to the uplink access point.
  • Introducing the 1024 QAM coding instead of the 256 QAM compared to the 802.11ac standard means sending a 10-bit word instead of an 8-bit one in the same unit of time.
  • Introducing the WPA3 standard. Together with new devices a new set of data transmission security measures was introduced and marked with the WPA3 code. These solutions were divided into two main groups: WPA3-Personal and WPA3-Enterprise. WPA3-Personal uses the SAE and Dragonfly Key Exchange algorithms which in short provide the security of the PSK password transmission needed to generate the session key. SAE makes the access devices resistant to the dictionary attacks and password recovery attempts during the transmission wire. On the other hand, the WPA3-Enterprise is not different from the point of view of IT techniques when compared to the WPA2. It was only enriches with the set of guidelines on the WPA3-CNSA settings and encryption options.


The access point of the wireless network work with higher and higher speeds often exceeding the standard possibilities of ethernet 1Gb/s. Delivering data to the access point through the ethernet network forces the higher speed network operation than currently available. Until now the 1Gb/s and 10Gb/s standards have been available. The latter required using the structural wiring in the form of fiber-optic wire or the ethernet cable of 6a category that often involved the infrastructure reconstruction. Introducing new standards marked 2.5GBASE-T and 5GBASE-T commonly known as the 802.3bz standard and working with the respective speeds of 2,5 and 5Gb/s provides the correct cooperation between the wireless and wired networks. Newly created standards can operate based on the wired infrastructure used for the 1Gb/s.
