Amarisoft 4G/5G SDR System

Description

This tutorial contains instructions for running the ​amarisoft eNB and UE on various platforms.

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 or 2 USRP X310s on COSMOS SB1 or Weeks Hall 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.

Tutorial Execution

Upon logging into the nodes, run eth_config.sh script to setup the 10G data interfaces on the nodes, DATA1, DATA2. After running the script, you should see that the data interfaces have the appropriate IP addresses assigned, as per the table ​https://wiki.cosmos-lab.org/wiki/Architecture/Domains/cosmos_sb1#IPAddressAssignment
