Calibrate the radio board
From YateBTS
Calibrate the Radio Board with MBTS
To calibrate the radio board you must adjust the RX gain until the noise RSSI reaches an average value of -70 dB or -120 dBm.
You can get the RX gain value using the command:
mbts rxgain
The output will be similar to this:
current RX gain is 47 dB
To adjust the Rx gain, you can use Yate's rmanager(Telnet) interface. Run the following command:
mbts rxgain <new value for RX gain>
Example:
mbts rxgain 45 current RX gain is 47 dB new RX gain is 45 dB
To get the noise value run the command:
mbts noise
The output will be similar to this:
noise RSSI is -68 dB wrt full scale MS RSSI target is -50 dB wrt full scale
If the noise value is not in the allowed values, try adjusting the RX gain again.
