10. Calibration
10.1 What’s the Rx Calibration?
10.1.1 Find proper AGC Gain to make the same Rx Power fed into the
Base Band Part regardless of Antenna Input Level
10.1.2 Can make report correct RSSI level
10.2 What’s the Tx Calibration?
10.2.1 To make Tx Power Level transmitted properly following the
information of Base Station
