Wi-Fi 7 introduces technologies such as 320MHz bandwidth, 4096-QAM, Multi-RU, multi-link operation, enhanced MU-MIMO, and multi-AP cooperation on the basis of Wi-Fi 6, making Wi-Fi 7 more powerful than Wi-Fi 7. Because Wi-Fi 6 will provide higher data transfer rates and lower latency. Ana sa ran Wi-Fi 7 don tallafawa kayan shiga har zuwa 30gbps, kusan sau uku na Wi-Fi 6.
