摘要: A method and system is disclosed for grouping the multiple stations connected to an access point (AP). The comprise sending a sounding packet plurality of stations, wherein may be all or part that are located within range AP. receive packets respond AP, AP determines channel state information (CSI) from responses. According CSI, divides into several groups. embodiment present invention, confirmation step performed each group respectively. sends second verifies CSI between station by group. Therefore, provides monitoring validation periodically
