Abstract
An air circulation control apparatus and method for a system such as a Base Transmission (or Transceiver) System (BTS) provides a control of an ambient air flow between inside and outside of the system. The apparatus includes at least one controller, such as a fan, and a member along an air flow path of the system. The member may be moveably mounted on the inside wall of the system. The controller operates in a forcing mode or a drawing mode to open or close the member so as to allow or not allow the air flow between inside and outside of the system.
