  • Patent number: 7929906
    Abstract: A forward and reverse link automatic power controlled repeater in an apparatus for measuring a path loss between a base-station and a repeater, includes a repeater control part device for controlling a repeater run and for processing forward and reverse gain of the repeater using received information. A mobile communication modem device transfers base-station signal information and base-station power transmission, and provides a wireless connection pathway of the repeater control part. A repeater element management system (EMS) device transfers information extracted from the base-station to the repeater control part and exchanges information with the repeater control part to control a repeater through the modem.
