    1 == COTS UE on ORBIT Node
     1== Basic LTE Tutorial ==
     2
     3=== Objective ===
     4
     5This tutorial presents a simple example of manually connecting LTE UE device to LTE basestation. It will use two nodes in the main ORBIT grid equipped with [wiki:Hardware/fDevices/dWide/341u Netgear AC341u LTE dongles] to connect to the same LTE basestation and then measure the throughput between them by runing iperf client and server.

    5 === Compatibility
     9=== Set up ===
    610
    7 In this tutorial we will use nodes equipped with Netgear AC341u LTE dongles. The basestation in use will depend on which one you have configured. The other tutorials specify which combinations are known to work well, as well as which nodes are close enough physically.
     11As a first step of this tutorial you need to [[CollapsibleStart(create grid reservation)]][[Include(Documentation/Short/CreateRes)]][[CollapsibleEnd]] and get it approved by the  [wiki:Documentation/Scheduler reservation service]. After receiving the reservation's confirmation (approval) email you need to prepare the nodes that will be used for this tutorial:
    812
    9 This particular LTE device operates only on the following Bands.
     13 * [[CollapsibleStart(Login into reserved domain: ssh username@grid.orbit-lab.org)]][[Include(Documentation/Short/Login)]][[CollapsibleEnd]]
     14 * [[CollapsibleStart(Load an image on the nodes: omf load -i baseline.ndz -t node1-7,node7-1)]] [[Include(Documentation/Short/LoadImage)]][[CollapsibleEnd]]
     15 * Turn the nodes back on [[CollapsibleStart(Turn on the nodes: omf tell -a on -t system:topo:imaged)]] [[Include(Documentation/Short/TellOn)]][[CollapsibleEnd]] (give them some time and check their status with '''omf stat''' before proceeding).

    11 * TX
    12  * Band 25: 1850-1915 MHz
    13  * Band 26: 814-849 MHz
    14  * Band 41 (TDD): 2496-2690 MHz
    15 * RX
    16  * Band 25: 1930-1995 MHz
    17  * Band 26: 859-894 MHz
    18  * Band 41 (TDD): 2496-2690 MHz

    20 === Imaging ===
    21 The image used for this experiment is 'baseline.ndz'.
    22 
    23 During a normal experiment using OMF, the following actions are scripted and automated. This is a look at the steps involved in something as simple as starting an LTE connection behind the scenes.
    24 
    25 You will run the following commands on node7-1 and node1-7 in the Grid.
    26 
    27 After connecting to the grid console:
    28 1. {{{ omf load -i baseline.ndz -t node7-1.grid.orbit-lab.org }}}
    29 1. {{{ omf tell -a on -t node7-1.grid.orbit-lab.org }}}
    30  1. It will take roughly 60 seconds to come up.
    31 1. {{{ ssh root@node7-1.grid.orbit-lab.org }}}
    32 1. repeat the above commands, replacing "node7-1" with the node name in question.
    33 
    34 === Commands on the node ===
     17Access the node with:
     18{{{
     19ssh root@node1-7
     20}}}

    3622==== Loading the driver ====

    38 By default ORBIT nodes do not enable any wireless devices. Therefore, the first thing when manually configuring the device is to load drivers; the following 2 lines will load the Sierra wireless Netgear LTE dongle:[[BR]]
