Abstract
According to an aspect of the inventive concept, there is provided a headend apparatus, including: a spectrum analysis unit analyzing frequency spectrums of a plurality of base station signals to detect characteristic information of the plurality of base station signals; a control unit transmitting the characteristic information to a network management server connected to the headend apparatus and outputting power control information, generated based on the characteristic information, received from the network management server; and a plurality of RF units receiving at least one of the plurality of base station signals and controlling power of the plurality of base station signals based on the power control information and outputting the plurality of base station signals.
Claims17
A headend apparatus, comprising:
- a spectrum analysis unit analyzing frequency spectrums of a plurality of base station signals to detect characteristic information of the plurality of base station signals;
- a control unit transmitting the characteristic information to a network management server connected to the headend apparatus and outputting power control information, generated based on the characteristic information, received from the network management server;
- and
- a plurality of RF units receiving at least one of the plurality of base station signals and controlling power of the plurality of base station signals based on the power control information and outputting the plurality of base station signals.
A distributed antenna system, comprising:
- a first base station interface unit analyzing frequency spectrums of a plurality of first base station signals received from a plurality of base stations connected thereto to detect first characteristic information, transmitting the first characteristic information, receiving combination power control information received to correspond to transmission of the first characteristic information, and controlling power of the first base station signals by using the combination power control information;
- a second base station interface unit analyzing frequency spectrums of a plurality of second base station signals received from at least one base station connected thereto to detect second characteristic information, transmitting the second characteristic information, receiving the combination power control information received to correspond to transmission of the second characteristic information, and controlling power of the second base station signal by using the combination power control information;
- and
- a network management server generating the combination power control information for controlling the power of the first base station signals and the second base station signal based on the first characteristic information and the second characteristic information and transmitting the combination power control information to the first and second base station interface units.
