The nation’s first open programmable advanced wireless research testbed
Platform Now in General Availability for Research
The POWDER-RENEW project is a collaboration between the University of Utah, Rice University and Salt Lake City, with broad support from community, municipal and state leadership. The purpose of the POWDER testbed is to enable innovative research across numerous technical areas including radio development for advanced networks including 5G, Radio Access Network (RAN) architectures, network orchestration models, Massive MIMO, and much more. The testbed provides state-of-the-art radio, compute, storage, and cloud resources, as well as the ability to work with existing hardware and software frameworks, or to build new ones from the ground up. Researchers can access the platform on site in Salt Lake City, or remotely from anywhere in the world.

SAMPLE AVENUES OF RESEARCH
Open RAN and Software-Defined RAN
The transition to open and software defined networks is driving demand for improvements in the software used to manage the RAN. POWDER provides an outdoor testbed that gives researchers the ability to customize, reconfigure, and control both the software and hardware parameters of a radio access network, offering a unique setting for developing algorithms and optimization frameworks that target specific performance improvements or efficiency gains.
POWDER provides an outdoor, production environment for testing the performance of Dynamic Spectrum Sharing (DSS) algorithms and Spectrum Access Sharing (SAS) solutions. This research is important for understanding the extent to which spectrum can be reused, and for calculating the impact of spectrum sharing on the network capacity available for both government and commercial use.
Many of the massive MIMO solutions currently available for purchase by carriers/operators from equipment vendors employ proprietary hardware and software schemes. The flexible, SDR-based RENEW base station currently deployed on POWDER allows an experimenter to test new massive MIMO algorithms and application scenarios.
