Amarisoft 4G/5G SDR System

Description

This tutorial contains instructions for running the ​amarisoft 5G NR base station and UE simulator on USRP N310s in COSMOS SB1. Amarisoft provides software based gNB, 5GCore (eNB,EPC) that run on commodity off-the-shelf devices. The software generates and sends baseband signals to the RF front-end for digital to analog conversion. Various RF front-ends are supported, including USRP N310, USRP X310. In this tutorial, we run 5GCore, gNB on a server+USRP N310, and the UE simulator on another server+USRP N310 in COSMOS SB1, in stand-alone (SA) mode. The UE simulator can simulate one or more UEs, enabling experiments with large number of users connected to a base station.

Prerequisites

In order to access the test bed, create a reservation and have it approved by the reservation service. Access to the resources is granted after the reservation is confirmed. Please follow the process shown on the COSMOS getting started page to get started.

Resources required

2 servers, 2 USRP N310s in ​COSMOS SB1 domain

Tutorial Setup

Follow the steps below to gain access to the sandbox 1 console and set up nodes with appropriate images.

  1. If you don't have one already, sign up for a ​COSMOS account
  2. Create a resource reservation on sandbox 1
  3. Login into sandbox 1 console (console.sb1.cosmos-lab.org) with two SSH sessions.
  4. Make sure all the resources in the domain are turned off: 
    omf tell -a offh -t system:topo:allres
    For this tutorial we will be using the SB1 servers, srv1-lg1, srv2-lg1 and USRP N310s, sdr1-md1, sdr1-s1-lg1
  5. Load amarisoft-tutorial-cosmos.ndz on srv1-lg1,srv2-lg1. 
    omf load -i amarisoft-tutorial-cosmos.ndz -t srv1-lg1,srv2-lg1
  6. Turn all the required resources on and check the status 
    omf tell -a on -t srv1-lg1,srv2-lg1,sdr1-md1,sdr1-s1-lg1

    omf stat -t system:topo:allres
  7. ssh to the nodes, use option -Y for using GUI.
