What Is Wi-Fi 6 and What Are the Differences Between Different Wi-Fi Level Version?

Wi-Fi 6 (formerly known as: 802.11.ax) is the name of the Wi-Fi standard. Wi-Fi 6 will allow communication with up to 8 devices at a speed of 9.6 Gbps.

On September 16, 2019, the Wi-Fi Alliance announced the launch of the Wi-Fi 6 certification program. The plan is to bring devices using the next-generation 802.11ax Wi-Fi wireless communication technology to established standards.

Wi-Fi 6 uses a technology called MU-MIMO (Multiple User Multiple Input Multiple Output), which allows routers to communicate with multiple devices at the same time, instead of communicating sequentially. MU-MIMO allows the router to communicate with four devices at a time, and Wi-Fi 6 will allow communication with up to 8 devices. Wi-Fi 6 also utilizes other technologies, such as OFDMA (Orthogonal Frequency Division Multiple Access) and transmit beamforming, both of which increase efficiency and network capacity, respectively. Wi-Fi 6 speed is 9.6 Gbps.

A new technology in Wi-Fi 6 allows devices to plan communications with routers, reducing the time required to keep antennas sung to transmit and search signals, which means reducing battery consumption and improving battery life.

Wi-Fi 6 devices must use WPA3 if they want to be certified by the Wi-Fi Alliance, so once the certification program is launched, most Wi-Fi 6 devices will be more secure.

The launch of the Wi-Fi 6 standard will also bring a “technical life extension” and a substantial increase in competitiveness to Wi-Fi technology, and will bring “a new era of Wi-Fi”.
