    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/OpenAirLXRT OAI_real-time_LTEsoftmodem] tutorial.

    7 The image used for this experiment is oai-trunk-full.ndz. Image uses Ubunutu 14.04 and has low-latency 3.17 kernel install and UHD drivers needed for B210/X310 USRPs (UHD 3.8.2)) as well as the !OpenAirInteface source code installed in /root/trunk (svn tag 668). The code was compiled with USRP support i.e. with:
     7The image used for this experiment is oai-trunk-head.ndz. Image uses Ubunutu 14.04 and has low-latency 3.19 kernel install and UHD drivers needed for B210/X310 USRPs (UHD 3.8.2)). This image was derived from vanilla image ubuntu-14-04-64bit-3.19-lowlatency.ndz (that was created based on [https://gitlab.eurecom.fr/oai/openairinterface5g/wikis/OpenAirKernelMainSetup OpenAir instructions]) from ubutbu-14-04-64bit.ndz (baseline.ndz). In addition to installation steps in !OpenAir documentation, once low latency kernel was installed, [wiki:Software/hDrivers drivers for Broadcom and Netgear devices] had to be manually re-installed.

     9Two images were created based on [https://gitlab.eurecom.fr/oai/openairinterface5g/wikis/GetSources git cloning instructions] and [https://gitlab.eurecom.fr/oai/openairinterface5g/wikis/AutoBuild compiling instructions]:

     15The openair-cn (EPC) was installed with default passwords of '''oai''' and default choice of "N" for optional packages (freeDiameter, asn1c pach and xtables_addons_oai). xtables_addons_oai was pulled out of git but not installed.
