Powder (the Platform for Open Wireless Data-driven Experimental Research) is flexible infrastructure enabling a wide range of software-defined experiments on the future of wireless networks.
Powder supports software-programmable experimentation on 5G and beyond, massive MIMO, ORAN, spectrum sharing and CBRS, RF monitoring, and anything else that can be supported on software-defined radios.
Powder is built to get your idea from the lab out into the real world. To get started, it
has several tightly-controlled environments:
a wired test bench,
a controllable attenuator,
From there, you can move to a number of end-to-end software-defined over-the-air experimental environments, including
Powder enables experimenters to build their own 5G networks using open-source software stacks such as OpenAirInterface and srsRAN. These networks are end-to-end programmable, allowing full control over both the RAN and core parts of the network, as well as the services that run inside. These networks can be built in a small indoor test environment or in an outdoor environment with several gNodeBs and true mobile devices.
Powder is a member of the O-RAN Alliance, and makes it possible to run the reference RIC in connection with open source mobility stack. In addition, Powder adds RAN slicing functionality to the reference RIC.
POWDER’s RF monitoring capabilities span across multiple vantage points and technologies. From rooftop sites with large sample rate SDRs, to small form factor fixed location and mobile units with modest SDR and compute resources. Antennas allow for either specific band coverage (e.g., CBRS), or wide range for tuning in FR1 frequencies (e.g., 700 MHz to 6 GHz).
POWDER provides multiple rooftop sites on and near the U of U campus with CBRS band radio access (3550 - 3700 MHz). In addition, all Fixed Endpoint (side of buildings, at human height) sites include CBRS capabilities. These CBRS resources are realized by direct NI USRP software defined radio connections (no additional RF front-ends) for shorter range, or low bandwidth communications.

We recommend that users of Powder join the powder-users mailing list. The list has a searchable archive, and is a good place to direct questions that are of general interest to Powder's user community.
