Abstract

A system and method are disclosed that may allow a STA to request one or more non-associated APs to initiate channel sounding operations with the STA. In response to the request, a number of the non-associated APs may send one or more NDPs to the STA. The STA may use the received NDPs to determine a goodput value for each of the number of non-associated APs. The STA may then use the determined goodput values to select one of the number of non-associated APs with which to associate. Thereafter, the STA may initiate an association operation with the selected AP.
