  • Apparatus for regulating transmission power of repeater in long term evolution system
    Patent number: 9231689
    Abstract: The present invention relates to an apparatus capable of flexibly regulating coverage of a repeater in a long term evolution system (hereinafter referred to as an LTE system). The present invention provides an apparatus for regulating transmission power of a repeater in an LTE (LONG TERM EVOLUTION) system, the apparatus including a sink signal detector that detects a sink signal of a reception signal received through an IF/RF receiver of the repeater, a sink signal power measurer that measures a size of power of the sink signal detected through the sink signal detector, and an amplification controller that calculates a gain of an amplifier of the repeater for maintaining coverage of the repeater based on the size of the power of the sink signal measured through the sink signal power measurer, and controls the amplifier of the repeater according to the calculated gain.
