This tutorial contains instructions for running srsLTE eNB and UE on COSMOS.
A more detailed tutorial can be found [here](https://github.com/srsLTE/srsLTE), with further links to specific help pages and the mailing list.

== Prerequisites ==
1. Two nodes, with appropriate hardware, within RF range
1. Currently supported: USRP X310, USRP B210
1. Load the image {{{tutorial-srslte.ndz}}} onto both nodes
1. Turn the nodes on
1. ssh to the nodes

== On node 1 ==
1. run srsepc
1. run srsenb


For further configuration details, please consult the official srsLTE webpage and documentation.

== On node 2 ==
1. run srsue


== Once Both nodes are running ==
* if all is successful, you should see new interfaces on the two nodes, with addresses:
  * 172.16.0.1
  * 172.16.0.2
* you should be able to run ping, iperf, and so on


== Specifics per domain ==
=== sb2.cosmos-lab.org ===
1. set usrp address to "type=x3xx,resource=rio0"
1. use RFSWITCH service to set all switches to port 1 for antenna

=== sb2.orbit-lab.org ===
1. set usrp address to "type=x3xx,addr=192.168.40.2"
1. bring up usrp ethernet interface, set ip to 192.168.40.1/16

=== sb1.orbit-lab.org ===
1. set usrp address to "type=b210"

=== sb4.orbit-lab.org ===
1. set usrp address to "type=b210"
1. configure RF matrix for 60db of attenuation between eNB and UE node chosen
