platform to design and prototype controllers in simulation and implement them
in real-world systems using a unified software architecture that easily takes
students from the simulation environment and with a toggle switch on the
LabVIEW front panel to deploy their controller to the physical hardware.

Student Course Feedback:
Awesome class! I really enjoyed the lectures, where I
learned a lot, and the labs were really cool because we
got to use the hardware.
… I am glad that I took this class!

Needs:
• Exposure to real-world signals
• Recruit students to
RF/Communications early
• Prepare students for research
Solution:
• SDR Platform
• Lower learning curve
• Maintainable
• Affordable
“The course evaluations for our class was fantastic.
Students rated the class 4.94/5.0, likely one of the
highest ratings among all classes in the School of
Engineering at Stanford.”

Research
COGEU Research – 7th Framework
Needs:
• Mobile demonstration of
whitespace utilization
• Multi university collaboration
• Graphics: key to getting funding
from non-engineers
Solution:
• Affordable research platform
across universities
• Easy graphical interfaces to make
prototypes attractive and intuitive
• Low learning curve to maximize
productivity
“Our students learn LabVIEW as undergraduates so
they are immediately productive and the graphical
capabilities allow our research projects to stand out.”
Dr. Paulo Marques , Senior Research Engineer
