9 and 10 are graphs illustrating forward overpower and low power phenomena of an RF repeater.

9 and 10, when the RF repeater 14 is forward overpower, the RF repeater 14 may not operate normally. In other words, upon forward over output of the RF repeater 14, the RF repeater 14 is either down or incapable of talking. Therefore, the high frequency signal is not amplified during the forward over-output of the RF repeater 14, and thus the monitoring device 10 may not operate properly.

When the RF repeater 14 has a low forward power, the RF repeater 14 does not amplify the high frequency signal to a desired level. Therefore, when the RF repeater 14 has a low forward power, a disconnection of the call and a call break may occur. Such forward and low output phenomena of the RF repeater 14 can be seen in the call test mode and the log data transmission mode of the monitoring apparatus of the present invention. In other words, through the log data and the call test mode, it is possible to grasp the forward low power and the high power of the RF repeater 14, thereby enabling quick response.

11 and 12 are graphs illustrating reverse overpower and low power phenomena of an RF repeater.

11 and 12, noise is generated during a call when the RF repeater 14 is reverse overpower and low power. Such reverse overpower of the RF repeater 14 can be grasped by the call test mode of the monitoring apparatus of the present invention. In other words, by checking the call quality in the call test mode, it is possible to grasp the reverse overpower and low power of the RF repeater 14, thereby enabling a quick response.

13 to 15 are graphs showing when the RF repeater has failed.

13 to 15, when the RF repeater 14 fails, an output lower than the normal output appears. That is, when a specific RF repeater 14 fails, a call is attempted using a signal of an RF repeater in another region adjacent to each other, and thus a graph of a low output when the RF repeater 14 fails. The failure of the RF repeater 14 can be grasped by the SMS test mode, log data transmission mode, call test mode and the like of the monitoring apparatus of the present invention.

As described above, according to the method and system for remotely monitoring the operating state of the high frequency repeater according to the present invention, a monitoring device for monitoring the RF repeater is installed in each region where the RF repeater is installed. Therefore, in the present invention, it is possible to determine whether the RF repeater is normally operated by checking the operation state of the monitoring apparatus.
