[srsran-users] [EXTERNAL] How to Run the SRS RAN 4G Signal Under 2.1 GHz?

[Sackman (US), Ronald W]

Hi Chao-Hwa,

In our lab, this is how we specify the LTE frequency.

In the enb.conf file, modify the dl_earfcn parameter to the target frequency.

In the ue.conf file, modify the dl_earfcn parameter to match the parameter in enb.conf

We use the following link to identify dl_earfcn.  When you specify the downlink EARFCN,
the uplink EARFCN is automatically specified.

To whom it may concern,

I am testing the SRS RAN. 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?

Thank you very much.
