The other day, the new IEEE 802.11ax wireless standard was approved and certified. It was renamed Wi-Fi 6 to make it clearer for users. Thus, the current 802.11ac standard is called Wi-Fi 5, and the previous 802.11n is called Wi-Fi 4. Wi-Fi 6 will not only launch a wave of new devices with new wireless capabilities but also contribute to the creation of next-generation networks with bigger speed and bandwidth.
Technically, Wi-Fi 6 has a data transfer rate that is 37% faster than 802.11ac, but more importantly, the updated specification offers 4 times greater bandwidth per user in crowded places, as well as higher energy efficiency, which should lead to an extended battery life of devices.
To achieve these improvements, the 802.11ax standard went through many changes, including several multi-user technologies borrowed from the cellular industry, namely MU-MIMO and OFDMA technologies, which significantly increase bandwidth and performance due to more simultaneous connections and more careful use of the spectrum.
Home users who can buy the new Wi-Fi 6 will be able to experience notable improvements from these technologies, especially over time. The number of devices per room is increasing every year – experts suggest that there will be up to 50 connections from different gadgets via Wi-Fi in each house by 2022, so the wide bandwidth of the channel is extremely important.
