POWDER Radio Dynamic Zone



OpenZMS is a prototype automatic spectrum-sharing management system for radio
dynamic zones. OpenZMS provides mechanisms to share electromagnetic
(radio-frequency) spectrum between experimental or test systems and existing
spectrum users, and between multiple experimental systems. We are building and
deploying OpenZMS within the context of the POWDER testbed in Salt Lake City,
Utah, part of the NSF-sponsored Platforms for Advanced Wireless Research
program, to create POWDER-RDZ.


Spectrum access challenges currently create significant constraints on
experimentation and testing at wireless testbeds. Automatic spectrum sharing
that provides safe access to additional frequencies beyond those reserved
exclusively for testing will relax these constraints, and thus increase the
nation's capacity to conduct wireless research and development. Increasing this
capacity will help accelerate growth and global leadership of the US
communications industry, strengthen academic research into wireless systems, and
benefit other spectrum-dependent sectors such as radar, public safety, and
national defense.


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 implements a modular zone management system (ZMS) to manage, control,
and monitor all 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.
