     7The first section of this tutorial briefly describes the '''ORBIT Radio Grid Testbed''', its system architecture and its hardware and software components.  The second section describes a simple "Hello World" experiment with one sender and one receiver.  The third and concluding section covers each of the steps that may be involved in the design, development, execution and interpretation of an '''ORBIT Radio Grid Testbed''' experiment.

The ORBIT Hardware components are described on this page http://www.orbit-lab.org/doc/design/hardware on this site, and the ORBIT Software Components are described here http://www.orbit-lab.org/doc/design/software.
