The Wireless Spectrum R&D Interagency Working Group (WSRD) held a workshop, “Wireless Spectrum Sharing: Enforcement Framework, Technology and R&D”, on May 5th, 2016 in Washington, DC 20001. The workshop focused on spectrum sharing enforcement issues and provided a forum for information exchange and the identification of relevant research and development opportunities. WSRD members will use information gathered from this workshop to develop recommendations for the White House Office of Science and Technology Policy (OSTP).
This workshop series stems from the Presidential memorandum issued on June 14, 2013, Expanding America’s Leadership in Wireless Innovation and has focused on ways to make more wireless spectrum available by encouraging shared access by commercial and Federal users. As with any sharing environment, such as the way aircraft share airspace or vehicles share the roads, underlying enforcement principles for spectrum sharing are critical. Industry and government innovators agree that enforcement is a necessary component for any dynamic spectrum sharing environment to be meaningful and effective.
Enforcement needs for wireless spectrum sharing extends well beyond just the enforcement of usage rights (i.e. interference protection). A complete enforcement regime (1) should explicitly recognize that enforcement requirements are bi-lateral (i.e., apply to the primary user as well as the secondary user), and (2) should also include the collective action rights - which encompass management rights (determining which users get to transmit when), exclusion rights (who gets to transmit at all) and alienation rights (who gets to sell the resource). To support a dynamic spectrum sharing environment, consistent and sustainable technology mechanisms are needed to monitor, detect, evaluate or adjudicate, classify, inform, and enforce compliance of the enforcement regime. Enforcement frameworks can rely on central architectures based on data clouds or device level distributed architectures, or a combination of both. This may entail adopting new standards or developing automated enforcement mechanisms and compliance certification methods for next-generation technologies to support the enforcement regime. Other issues to be considered include enforcement-related privacy and security issues, and the economic tradeoffs in ex ante and ex post enforcement mechanisms.
