1 year ago To change the frequency you need to adjust the EARFCN. Therefore, please refer to [1]. To translate EARFCNs to frequencies refer to [2].

Issue Description
I am testing the SRSRAN 4G. When I run the UE, the download frequency is 2.68 GHz, while the uplink frequency is 2.56 GHz. I want to see whether the signal is transmitted; however, my spectrum analyzer can only display the signal below 2.1 GHz.
How can I change the configurations such that the SRSRAN 4G signal can be transmitted under 2.1 GHz?
