I read some ipw docu and found this:

For example:
        /sys/bus/pci/drivers/ipw3945/0000:02:01.0

For the device level files, see /sys/bus/pci/drivers/ipw3945:

  rf_kill
        read -
        0 = RF kill not enabled (radio on)
        1 = SW based RF kill active (radio off)
        2 = HW based RF kill active (radio off)
        3 = Both HW and SW RF kill active (radio off)

        write -
        0 = If SW based RF kill active, turn the radio back on
        1 = If radio is on, activate SW based RF kill

        NOTE: If you enable the SW based RF kill and then toggle the HW
        based RF kill from ON -> OFF -> ON, the radio will NOT come back on
