Hi SagarPawar14,
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 maximum speed of 9.6Gbps.
Wi-Fi 6 mainly uses OFDMA, MU-MIMO, and other technologies. The MU-MIMO (Multi-User Multiple-Input Multiple-Output) technology 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 can reach a maximum speed of 9.6Gbps.
New technology in Wi-Fi 6 allows devices to plan communication with the router, reducing the time required to keep the antenna powered on to transmit and search for signals, which means less battery consumption and improved 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.
