== !OpenAirInterface LTE == 

[[Include(Documentation/Short/Prereq)]]

This 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]. 

=== Prepare the testbed ===

 1. Load the image with the !OpenAirInterface code on the nodes that have USRP B210 attached. After imaging the nodes are '''turned off automatically'''.

 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]]
