    99Amarisoft provides software based gNB, 5GCore (eNB,EPC), and UE simulator that run on commodity off-the-shelf devices. A typical software-based cellular basestation/UE consists of a host PC and an SDR, where host PC is used for processing the baseband signals sent to and received from the SDR. Amarisoft supports various SDRs including USRPs such as N310, X310.
    1010In this tutorial, we run 5GCore, gNB(SA) on a host server+USRP N310 in COSMOS SB1. The UEs used in this experiment are

    49 * Upon logging into the nodes, run eth_config.sh script on both the nodes. This sets up the 10G data interfaces DATA1, DATA2. After running the script, you should see that the data interfaces have the appropriate IP addresses assigned, as per this [https://wiki.cosmos-lab.org/wiki/Architecture/Domains/cosmos_sb1#IPAddressAssignment table]. The nodes should then be able to access the USRP N310s sdr1-s1-lg1 and sdr1-md1 which can be checked by running uhd_find_devices.
