= Simple radio example with GNURADIO benchmark scripts =

== Description ==
This example will utilize an OEDL script to execute packet transfers over a radio link created using GNU Radio. This is will involve running a GNU Radio benchmark script two nodes each with a USRP.

== Hardware / Software Resources utilized ==
 1. Grid nodes with a USRP2 connect via Ethernet.
 2. ''baseline-12-04-gnu.ndz'': disk image loaded onto nodes. This image has all the precompiled - software required to configure the USRPs and all the required GNU Radio libraries. The USRP2's interface with the node is already configured.
 3. gnu-benchmark.rb - OEDL script to set up a GNU Radio system and execute a simple data transfer.

== Set up ==
 * To get started first make a reservation on the [https://www.orbit-lab.org/schedule/ Orbit Scheduler] for using the Grid.

 * After logging into grid console, make sure all nodes are turned off
{{{
nilanjan@console.grid:~$ omf tell -a offh -t system:topo:all
}}}

 * Verify state of node before continuing. Make sure all nodes are in the POWEROFF state.
{{{
nilanjan@console.grid:~$ omf stat
}}}

 * Image nodes. Two (2) are required to run - check [https://www.orbit-lab.org/status/orbit/ inventory status] to find nodes with USRP2s.
{{{
nilanjan@console.grid:~$ omf load -i baseline-12-04-gnu.ndz -t node1-1,node1-2
}}}

 * Turn nodes back on and verify they are in POWERON state
{{{
nilanjan@console.grid:~$ omf tell -a on -t system:topo:imaged
}}}
