Abstract

Una estacion inalámbrica (114) está dentro del alcance de más de un punto de acceso (120, 124) que transmite en el mismo canal. La estacion inalámbrica está asociada con un punto de acceso y no con el otro. Por consiguiente, la estacion inalámbrica puede recibir balizas no deseadas (304) y baliza deseadas (302) en el canal. Para optimizar la operacion de ahorro de energía la estacion inalámbrica arbitra entre un procedimiento de barrido de canal de barrido y cierre (708) y un procedimiento de barrido de canal de ventana temporizada (724), segun la baliza deseada sea o no la primera baliza recibida al despertar de un estado de bajo consumo a una hora objetivo de busqueda de baliza.
