[[Include(Documentation/Short/Prereq)]]
=== Imaging ===
The image used for this experiment is 'baseline.ndz'. In this tutorial we will use nodes equipped with Netgear AC341u LTE dongles. The basestation is Amarisoft running on Bsc03out.

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.

You will run the following commands on node7-1.grid.orbit-lab.org

After connecting to the grid console:
1. {{{ omf load -i baseline.ndz -t node7-1.grid.orbit-lab.org }}}
1. {{{ omf tell -a on -t node7-1.grid.orbit-lab.org }}}
 1. It will take roughly 60 seconds to come up.
1. {{{ ssh root@node7-1.grid.orbit-lab.org }}}
=== Commands on the node ===
By Default Orbit nodes do not configure any wireless devices. The following 2 are the drivers for the Sierra wireless Netgear LTE dongle [[BR]]
1. {{{ modprobe GobiSerial }}}
1. {{{ modprobe GobiNet }}}
1. {{{ minicom -D /dev/ttyUSB1 }}}
1. {{{ AT!ippassthrough? }}}
 1. It should return 1
 1. If it does not, run {{{ AT!ippassthrough=1 }}} then {{{ AT!reset }}}
1. {{{ AT!entercnd="A710" }}}
 1. You should see {{{ OK }}}
1. {{{AT!dxcfg=profile,Autoconnect,Never}}}
1. {{{ AT!dxcfg=wwan,connect,11 }}}
 1. You should see {{{ OK }}} then {{{ $QCRMCALL: 1, V4 }}}
1. {{{ at!gstatus? }}}
 1. Will return a status like: 
{{{
at!gstatus?

1. Exit Minicom by **PRESSING** {{{ Ctrl+A followed by x}}}, then {{{enter}}} to select ok.
1. {{{ dhcpcd eth2 }}} followed by {{{enter}}} to get a new line.
 1. You should get an address in the 192.168.3.0/24 subnet.
1. {{{ ping 192.168.3.1 }}}
 1. You have successfully communicated with the basestation.
 1. You can cancel the ping with {{{Ctrl+C}}}
1. {{{iperf -c 192.168.3.1 }}}
 1. This will report your bandwidth to the basestation.
