Local 5G monitoring system and measurement data providing method thereof

A local 5G monitoring system that monitors a local 5G system, comprising:

• a plurality of measuring devices comprising at least one mobile terminal that support 5G communication and at least one measurement device that measures radio waves from a base station of the local 5G system;
• a first server device that belongs to the same local area network (LAN) as the plurality of measuring devices, and collects measurement data from the plurality of measuring devices;
• and
• a second server device not belonging to the LAN network that is connected to the first server device via the Internet, and is configured to be referred to by a user,
• wherein the first server device is configured to transmit the measurement data to the second server device via the Internet,
• wherein the first server device uses the measurement data from the plurality of measuring devices when installation of the local 5G system is completed, as reference information, and determines and notifies the user that an abnormal state occurs, when the measurement data from the plurality of measuring devices during an operation of the local 5G system exceeds a threshold from the reference information,
• wherein the first server determines an abnormal state based on whether measurement data of a predetermined number of measuring devices exceeds a threshold from the reference information and deteriorates, and
• wherein the threshold is based on the installation position of the measuring devices.
