1. an operation comprises the method for client stations in the wireless lan communication system of an access point, and this client stations comprises an antenna steering algorithm and responds the smart antenna that this antenna steering algorithm is selected one of a plurality of antenna beams, and this method comprises:

  • Select a preferred antenna beam and an alternate antenna beam;

    In not carrying out between the lasting operating period of scanning other antenna beam again, use this preferred antenna beam and this access point swap data;

    In continue periodically to calculate between the operating period this preferred antenna beam this by a quality metric of swap data, this calculating comprises;

    This that determines this preferred antenna beam is by at least one link quality Centrifugal filtrate of swap data;

    This that determines this preferred antenna beam is by a quality metric of exchange data signals;

    AndMake up this at least one link quality Centrifugal filtrate and this signal quality metric and calculate this quality metric;

    Relatively this quality metric of this preferred antenna beam and exchanges the threshold scope;

    AndIf this quality metric in this exchange threshold scope, then exchanges this preferred antenna beam and this alternate antenna beam so that continue at interior and this access point swap data between this lasting operating period.
