Wi-Fi is getting faster and faster. Many routers already have access to chips using the 802.11 draft ax Wi-Fi standard, but the new rule should be adopted by December 2019, which will trigger a wave of more modern devices with new wireless features. They will help create next-generation networks with less latency and higher speeds.

Ax 802.11 standard or “efficient wireless” is now called Wi-Fi6. The new rule provided by the Wi-Fi Union and previous generations is now called Wi-Fi 4(802.11n) and Wi-Fi 5(802.11ac). It is expected that the new marking will soon appear on the equipment, as shown below.

Technically, the Wi-Fi 6 single-user data transmission rate is 37% faster than ac 802.11. More importantly, the updated specification will provide four times the bandwidth per user on a wireless network with a large number of devices. It also has higher energy efficiency, which will lead to the improvement of battery autonomy. Many changes have been made to achieve these improvements in the 802.11 ax standard, including some multiuser technologies adopted by the cellular industry, i.e., OFDMA and MU-MIMO, which significantly improve throughput and performance due to the simultaneous increase in the number of connections. And more advanced methods of using data bandwidth.

As mentioned earlier, Wi-Fi6 is expected to have a more direct impact in areas with severe network overload and ultimately lay the foundation for the anticipated future of smart infrastructure (e.g., the Internet of things).

Apart from addressing equipment and network deployment problems caused by the deployment of the Internet of things, Wi-Fi 6 will adapt to the growing demand for higher data rates users. Wi-Fi 6 802.11-based ac, has approximately or more 50 update features, although not all of these will be included in the final specification.

Below are some of Wi-Fi 6 expected accomplishments:

  ·Higher bandwidth per user for virtual reality and ultra-HD streaming
  ·Support more concurrent data streams with increased bandwidth
  ·Spread spectrum (2.4 GHz and 5 GHz, eventually 1 GHz and 6 GHz frequencies are expected)
  ·Splitting spectrum into several frequencies, this will provide more full channels for data transmission.
  ·Improved performance (4 times) at a maximum distance of the access point
  ·Better performance/reliability in outdoor and multipath (cluttered) conditions

Wi-Fi 6 also introduced support (OFDMA) for incoming and outgoing communication lines, a modulation scheme equivalent to an OFDM multiuser version. It will reduce waiting time, improve throughput and efficiency, and allow 30 users to use the channel simultaneously.


To replace 802.11 n and 802.11 ac as the next WLAN standard,802.11 axes or Wi-Fi 6, are being developed to significantly improve network efficiency and throughput in dense regions and moderately increase peak data rates to better support simultaneous use of multiple devices.
