The donor unit may include a first signal processing unit for dividing a signal received from the base station into a plurality of frequency bands and providing the amplified signal to the amplifying unit and combining signals transmitted from the amplifying unit, A second signal processing part for dividing the frequency band into the frequency bands and providing the amplified signals to the amplifying part, and combining the signals transmitted from the amplifying part; .

The extracting unit may include: a first extracting unit that extracts a propagation environment value of a specific signal among signals received from the base station and signals distributed through the first signal processing unit; A second extracting unit for extracting a propagation environment value of a specific signal among the signals combined through the first signal processing unit and the amplifying unit and through the second signal processing unit; A communication part for communicating with the operating server; A switch portion connecting one of the first extraction portion and the second extraction portion to the communication portion; And a control unit.

The amplifying unit 130 connects the first signal processing unit 111 and the second signal processing unit 121 and outputs the signal distributed in the first signal processing unit 111 to the second signal processing unit 121 Amplification.

The amplifying unit 130 connects the second signal processing unit 121 and the first signal processing unit 111 to output the signal divided in the second signal processing unit 121 to the first signal processing unit 111 Amplification.

The extracting unit 140 extracts a specific frequency signal from the signals transmitted from the donor unit 110 or the service unit 120 and transmits the extracted frequency signal to the operating server 400. The extracting unit 140 extracts the first extracting unit 141, An extraction portion 142, a switch portion 144, and a communication portion 143. [

For example, before the first signal processing portion 111 distributes the signal received from the base station 200 via the donor portion 110, the first extracting portion 141 extracts the propagation environment value .

Thereafter, the first signal processing part 111 transmits the distributed signal to the amplifying part 130, amplifies the signal, and sends the amplified signal to the second signal processing part 121.

The second signal processing unit 121 combines the signals of the frequency bands transmitted from the amplifying unit 130 and the second extracting unit 142 extracts the propagation environment values of the specific signal from the combined signals .

The propagation environment values of the specific signals respectively extracted by the first extracting section 141 and the second extracting section 142 are transmitted to the operating server 400 through the communication section 143.

The communication section 143 can provide the operation environment value of the signal provided through the switch section 144 to be described later to the operation side server 400 and can control the relay device 100 to control the relay device 100 from the operation side server 400 A signal can be received.
