Wi-Fi is improving. Many routers are available with chips that use draft 802.11ax Wi Fi specifications. However, the new standard should not be adopted before December 2019. This will allow for a wave new devices with new wireless capabilities. They will enable the next generation of networks to be more efficient and faster.
Wi-Fi 6 will be the new name for the 802.11ax standard. This is “high-efficiency wireless”. This new standard is provided by Wi-Fi Alliance. The previous generations are Wi-Fi 4 (802.11n), and Wi-Fi 5 (802.11ac). As shown below, it is likely that a new type marking will soon appear on these devices.
Technically, Wi Fi 6 will have a single user data transfer rate of 37% faster that 802.11ac. But, more importantly, the updated specifications will provide 4 times the bandwidth per device on a wireless network with many devices. It is also more efficient which should result in a higher battery life. Many changes were made to the 802.11ax standard to achieve these improvements. These include multi-user technologies, such as OFDMA or MU-MIMO. These technologies significantly increase throughput due to a higher number of connections and more advanced ways to use data bandwidth.
Wi-Fi 6 will, as mentioned, have a greater impact on areas with overloaded networks and help to lay the foundations for the future of intelligent infrastructure (e.g. the Internet of things). Wi-Fi 6 will address the growing demand for higher data rates and solve problems associated with large numbers of devices and network deployments as IoT is deployed. Wi-Fi 6 uses 802.11ac and has approximately 50 new features. However, not all of these features will be included in final specifications. These are some of the expected achievements for Wi-Fi 6.
For Ultra-HD streaming and virtual reality, you will need more bandwidth.
Increased bandwidth and support for more concurrent data streams
Spread spectrum (2.4GHz and 5GHz, eventually 1GHz and 6GHz frequencies) are to be expected.
This will allow data transmission to be carried out over a wider spectrum by splitting it into multiple frequencies.
Performance up to 4 times at the maximum distance from the access point
Better performance/reliability in outdoor and multipath (cluttered) conditions
Wi-Fi 6 introduces support for OFDMA (outgoing and incoming communication lines), a modulation scheme which equates to multi-user OFDM. It will allow 30 users to simultaneously use this channel, reduce latency, increase throughput, and efficiency.
802.11ac and 802.11ac are being replaced by 802.11ax as the next WLAN standards. 802.11ax, or Wi-Fi 6, is being developed to provide significant network efficiency improvements for dense locations. It also offers moderate improvements in peak data speeds. Multiple devices will be supported better.
