    55This tutorial also assumes basic familiarity with [http://en.wikipedia.org/wiki/LTE_%28telecommunication%29 LTE standard]. It uses [http://www.openairinterface.org/ OpenAirInterface] open source software implementation of LTE basestation (eNodeB or eNB) and modem (user equipment or UE) developed at [http://www.eurecom.fr/en Eurecom].
    66
    7 === Prepare the testbed ===
     7The image used for this experiment is oai-rel_0.1-full.ndz. Image has low-latency 3.17 kernel install and UHD drivers needed for B210/X310 USRPs as well as the !OpenAirInteface source code installed in /root/rel_0.1_26.10.2014
     8
     9=== Prepare the nodes ===
    810
    911 1. Load the image with the !OpenAirInterface code on the nodes that have USRP B210 attached. After imaging the nodes are '''turned off automatically'''.
    10  [[CollapsibleStart(Load an image on the nodes: "omf load -i  -t inventory:topo:B210")]] [[Include(Documentation/Short/LoadImage)]][[CollapsibleEnd]]
    11  1. Turn ON the nodes that successfully imaged (give them some time and check their status with '''omf stat''' before proceeding). [[CollapsibleStart(Turn the nodes on: "omf tell -a on -t system:topo:imaged")]][[Include(Documentation/Short/TellOn)]][[CollapsibleEnd]]
     12 [[CollapsibleStart(omf load -t inventory:topo:B210 -i oai-rel_0.1-full.ndz)]] [[Include(Documentation/Short/LoadImage)]][[CollapsibleEnd]]
     13 1. Turn ON the nodes that successfully imaged (give them some time and check their status with '''omf stat''' before proceeding). [[CollapsibleStart(omf tell -a on -t system:topo:imaged)]][[Include(Documentation/Short/TellOn)]][[CollapsibleEnd]]
     14
     15=== Execute the experiment ===
     16
     17Primary objective is to establish the LTE connection between the UE and eNB. node6-20 = eNB node19-18 = UE...
     18 
     19
     20 || On the eNB node (node6-20) || On the UE node (node19-18)  ||
     21 ||  lte-softmodem -Ooai.conf   || lte-softmodem -U Ooai.conf ||
     22
     23Add "-d" flag if you have enabled X11 forwarding and want to see the signal tracer (requires relatively high bandwidth).
     24
     25The output on both consoles should look something like this:
