Classification: CPC H  Y | IPC H

Claim 1:
2. The transmitting and receiving antenna system of the repeater for the LPWAN of claim 1, wherein the controller includes control steps as a first step for changing to an automatic direction determination mode in the second antenna, a second step for transmitting a pilot message including a response request message in a uplink direction by initializing the directivity of the second antenna, a third step for analyzing a RSSI of the response message in the analyzer when the response message to the pilot message is received after a certain period of time, a fourth step for generating a control signal in a generator of controller, to change the position angle of the second antenna by the n-th order as amount of an allowable angle by repeating the second step and the third step up to n times, a fifth step for determining the direction in which the RSSI of the response message is analyzed in the highest in the analyzer after the n-th repetition, a sixth step for generating a control signal for determining the directivity of the second antenna in the generator based on the determination of the analyzer.
