System and method of compensating rssi signal for ble-based positioning

The present invention relates to a system and method for RSSI signal correction for BLE-based position measurements, comprising measuring a Received Signal Strength Indicator (RSSI) value of a beacon signal received from one or more beacon devices, The user terminal performing location measurement of the user terminal by calculating the distance information between the beacon device and the receiving user terminal by using RSSI values calculated according to the distance using the Friis formula and using the replaced RSSI value The error rate of the radio signal can be lowered and the accuracy of the indoor position measurement can be increased.
