  The TX power value - value of processors power output to antenna. Calibrated Power - in the Beacon protocol is a critical parameter that helps estimate the distance between a beacon and a receiving device. For example, this value is sent in Byte 29 of the iBeacon packet and is typically set to a predefined value in the sensor's configuration. It indicates the transmitting power of the beacon at a reference distance of 1 meter and is measured in decibels referenced to 1 milliwatt (dBm). RFU - Similarly to Calibarated Power, RFU is set for Eddystone protocols. The difference is iBeacon, the calibrated power is reference RSSI value that is the expected RSSI value at 1 meter from the beacon, while for Eddystone, it's the expected RSSI value at 0 meters. Currently Teltonika is providing beacons with pre-calibrated RSSI at 1m for iBeacon and RSSI at 0m for Eddystone that should be suitable for most use cases, however we plan to introduce user calibration in the future.
