The Rise of Prototyping and Test Beds
ni.com
“Designing a test bed as massive in scale as Colosseum from scratch would have required several years
of engineering time. Simply put, the alternatives to using NI’s off-the-shelf software radio tools presented
too much risk and cost.”
—Paul Tilghman , Program Manager, DARPA Spectrum Collaboration Challenge

Platforms for Enabling Advanced Wireless Research (PAWR)
“Experience shows that the real world often breaks some of the assumptions made in theoretical research, so testbeds are an important tool for evaluation under very realistic operating conditions”
“…development of a testbed that is able to test radical ideas in a complete, working system is crucial”

Splitting the User and Control Plane
• 5G proposes:
• Flexible numerologies, frame structure and TDD architectures
• Distribution control and intelligence
• Multiple RAT and coexistence
• PHY prototypes abstract control exploration – develop only “part” of the system
