Intersystem connection handover is based on transmission quality of a first radio communication system to a base station as determined by a subscriber station. The switchable impedance has an input coupled to the output of the charge pump. The method of assembly includes the steps of making a motor sub-assembly including a motor and a radial fan, the fan has a plurality of blades located on one side of the fan and non-rotatably mounting the fan on an end of the armature shaft of the motor at a first end of the motor with the blades facing away from the armature of the motor. The second location is at a network operations center configured to perform at least one control plane function.
