    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]. The tutorial given here is based on the [https://twiki.eurecom.fr/twiki/bin/view/OpenAirInterface/HowToConnectOAIENBWithOAIUEWithoutS1Interface] tutorial.

Image uses Ubunutu 14.04 and has low-latency 3.13 kernel install and UHD drivers needed for B210/X310 USRPs (UHD 3.8.2)) as well as the !OpenAirInteface source code installed in /root/openairinterface5g/. More details on various build options are available on [https://twiki.eurecom.fr/twiki/bin/view/OpenAirInterface/AutoBuild OpenAirInterface build page].

     55If the eNB was run using the graphical analyzer, after the connection is established and the pinging starts, the analyzer should look similar to the one shown on the picture below.
