OAI Remote Radio Head (RRH)

This tutorial assumes that you have an ORBIT account, and a reservation for grid.orbit-lab.org

In this tutorial, we demonstrate the operation of a split eNB, with one node managing a RF device, and sending I/Q samples to another node fro processing.

We will use the following resources:

  • node3-2.grid.orbit-lab.org as the RRH
  • node21-2.grid.orbit-lab.org as the eNB
  • node1-7.grid.orbit.lab.org as a client
  1. Execute the following commands on the grid console, from separate ssh sessions (They can be done at the same time)
    1. omf load -t node3-2,node21-2 -i msherman-oai-rrh.ndz
    2. omf load -t node1-7
  2. After they are imaged, turn the nodes on
    1. omf tell -a on -t node3-2,node21-2,node1-7
  3. Open a ssh session to each device
    1. ssh root@node3-2.grid.orbit-lab.org
    2. ssh root@node21-2.grid.orbit-lab.org
    3. ssh root@node1-7.grid.orbit-lab.org
  4. On node3-2
    1. Run script ./quickbuild_rrh.sh
    2. Run script ./run_rrh
  5. On node21-2
    1. Run script ./quickbuild_enb.sh
    2. Run script ./run_enb.sh

After executing both run scripts, you should see the RRH node load a USRP image, and the eNB node start printing log messages. Now, on node1-7, we will follow the instructions from the amarisoft tutorial to connect.
