Amarisoft 4G/5G SDR System

Description

This tutorial contains instructions for setting up ​amarisoft 5G NR network using SDRs(USRP N310/USRP 2974) in COSMOS SB1. Amarisoft 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 such as Amarisoft PCIe SDR50, SDR100, and USRPs such as N310, X310, 2974. In this tutorial, we run 5GCore, gNB(SA) on a host server+USRP N310 in COSMOS SB1, and the UE simulator on another host server+USRP 2974. 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 and 2 SDRs 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, USRP N310s in large and medium nodes, sdr1-s1-lg1 and sdr1-md1.
  5. Load 5G-tutorial-cosmos.ndz on srv1-lg1,srv2-lg1. 
    omf load -i 5G-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-s1-lg1,sdr1-md1

    omf stat -t system:topo:allres
  7. ssh to the servers, use option -Y for using GUI. 
    ssh root@srv1-lg1

    ssh root@srv2-lg1
