Is it justified by what I say? \r\nIs there a solution to ensure high speed and massive data transmission? \r\nFor example, in this case, AP can send beacon normally. \r\nI don't want to reduce sending speed and reduce the size of each packet. \r\nHowever, station sent the broadcast packet to AP to receive the solution, which is much better, but this is not what I want."}}
