Dr. Jerry Park Working with the NTIA and NSF to Organize a Wireless Spectrum R&D Senior Steering Group Workshop

Dr. Park and Dr. ReedDr. Jerry Park and Dr. Jeff Reed will be participating members of the planning committee for the Wireless Spectrum R&D (WSRD) Senior Steering Group (SSG) Workshop VI: Federal-Commercial Spectrum Data: Understanding Information Exchange Needs, Issues, and Approaches, which will be held in Arlington, VA on Oct. 21, 2014. This workshop, which is partially sponsored by the National Science Foundation (NSF), is being organized by the National Telecommunications and Information Administration (NTIA), the National Coordination Office (NCO), and selected representatives from academia. This invitational workshop will bring together highly-visible experts on wireless systems and spectrum management from the Federal Government, academia, and the private sector.  The primary goal of the workshop is to assist in developing recommendations for the Federal spectrum research portfolio. For more information, please visit WSRD.

Dr. Jerry Park, BWAC Site Director, and Dr. Marwan Krunz, U of AZ, Receive NSF Grant For Study of the Coexistence of Heterogeneous Secondary Networks

Dr. Park and Dr. KrunzRecently, Dr. Jerry Park, Site Director the Virginia Tech BWAC site, and Dr. Marwan Krunz, Co-Director of the University of Arizona BWAC site, were awarded a $200K grant from the National Science Foundation (NSF) to study the coexistence of heterogeneous secondary networks in spectrum sharing scenarios. Dr. Krunz is a professor in the Dept. of ECE at the University of Arizona. The U.S. government has been aggressively pushing new initiatives to identify and make available new swaths of spectrum to support the development of new wireless applications. It has also been promoting the development of new technologies and regulatory policies for enhancing spectrum utilization. Although coexistence issues in the ISM bands have been studied before, the situation in the TV bands and other shared access spectrum (e.g., 3.5 GHz band) is more complex and challenging due to the signal propagation characteristics, incumbent protection rules, and the disparity of PHY/MAC strategies of secondary systems. To date, most research efforts have focused on incumbent protection, and little attention has been given to the coexistence of secondary systems in the context of spectrum sharing. Dr. Park and Dr. Krunz hope to broaden the focus of research through this grant.


Dr. Jerry Park, Dr. Carl Dietrich, Dr. Vuk Marojevic and Dr. Jeff Reed Awarded Grant for LTE-enhanced Cognitive Radio Testbed.

prof's photosRecently, Drs. Jerry Park, Carl Dietrich, Vuk Marojevic, and Jeff Reed were awarded a grant for $250K from the Army Research Office (ARO) to design and build a LTE-enhanced cognitive radio testbed. Testbeds play a major role in developing and testing new wireless communications technologies and systems. Virginia Tech’s COgnitive Radio NETwork (CORNET) is a large-scale testbed featuring forty-eight remotely accessible software radio nodes that are used in education and research. The CORNET nodes enable dynamic spectrum access (DSA) and cognitive radio (CR) related research and education using open-source software and flexible hardware. CORNET is unique in that it offers a wide range of experimental research and educational tools, including an FCC experimental license agreement for several frequency bands. As communications systems gradually move towards 4G using long-term evolution (LTE) technology, LTE nodes need to be integrated into the CORNET testbed to be able to train engineers and students on this emerging technology and its evolution.

Awarded the Best Paper Award from 2014 IEEE DySPAN!

BWAC researchers, including Jerry Park, Behnam Bahrak, and Sudeep Bhattarai, received the Best Paper Award at the 2014 IEEE Symposium on New Frontiers in Dynamic Spectrum Access Networks (DySPAN). The paper is titled "Protecting the Primary Users' Operational Privacy in Spectrum Sharing." IEEE DySPAN is the premier conference to discuss, publish, and present recent advancements in Dynamic Spectrum Access (DSA) and Cognitive Radio, including novel approaches and technologies enabling more efficient use of the radio spectrum.
