OpenZMS and POWDER-RDZ

As a pathfinder for the National Radio Dynamic Zone concept, OpenZMS and POWDER-RDZ will help future federal/non-federal spectrum sharing arrangements assure that spectrum sharing does not negatively impact existing and incumbent spectrum use. By building and operating an end-to-end radio dynamic zone (RDZ), we will validate the RDZ concept and functionality by performing spectrum sharing experiments and field studies. The project uses the existing POWDER mobile and wireless testbed as the physical infrastructure of the RDZ. POWDER's existing radios and other equipment supports the spectrum sharing experiments and provides part of the RF sensing functionality needed by the RDZ.

POWDER-RDZ relies on the OpenZMS modular zone management system to manage, control, and monitor all radio aspects of the RDZ. The project plans to conduct experiments on spectrum sharing with users outside of POWDER. Experiments potentially include RDZ shared access to federal, non-federal, and commercial spectrum, such as coarse- and fine-grained spectrum sharing with a commercial mobile operator and spectrum sharing with a weather radar.
