Technically, Wi-Fi 6's single-user data rate is 37% faster than 802.11ac, but more importantly, the updated specification will provide four times the throughput and higher for each user in a crowded environment. Energy efficiency, which will increase the battery life of the device.

With the upcoming major update, Wi-Fi will get better and faster. Although many routers are already equipped with chips that use draft specifications, 802.11ax Wi-Fi was not fully finalized until it officially received Wi-Fi 6 certification in September 2019. The WIFI Alliance has also recently launched the WIFI 6 certification program. This will lead to a wave of newer devices that will sell new wireless features that will bring faster speed and less congestion to next-generation networks. But do you really know WIFI 6?

What we usually call Wi-Fi 6, which is 802.11ax, is also known as "efficient wireless." This is a new naming standard set by the Wi-Fi Alliance, which is now known as Wi-Fi 5 (802.11ac) and Wi-Fi 4 (802.11n). This label convention will appear on the device below.

Technically, Wi-Fi 6's single-user data rate is 37% faster than 802.11ac, but more importantly, the updated specification will provide four times the throughput and higher for each user in a crowded environment. Energy efficiency, which will increase the battery life of the device.

To achieve these improvements, 802.11ax has implemented a number of changes, including several multi-user technologies borrowed from the cellular industry, namely MU-MIMO and OFDMA, which greatly support the use of more simultaneous connections and more thorough use of the spectrum. Increased capacity and performance.

Home users upgrading their hardware can expect some improvements from these technologies, especially as the number of devices increases over time. Some estimates indicate that by 2022, each family will have as many as 50 nodes.

However, as mentioned earlier, Wi-Fi 6 is expected to have a more direct impact in highly congested areas of the network and ultimately help lay the groundwork for the number of nodes in the upcoming smart infrastructure, such as IoT devices. With the introduction of the Internet of Things, the number of devices and network deployments continues to increase, coverage continues to overlap, and Wi-Fi 6 will be deployed to meet the growing demand for faster multi-user data rates.
