Dynamic Spectrum Access (DSA) technologies have been proposed and researched for 15 years, yet only some relatively experimental systems are in operation today. This research explores some essential but unexplored techno-economic aspects of DSA that are crucial if these systems are to come to commercial reality. One major thrust is an exploration of how substitutable different frequency bands that these systems might use are with each other. Another major thrust is how a firm that might be considering the use of DSA technologies can manage the technical and financial risk inherent in them. To accomplish this, a fungibility score based on mathematical models and agent-based simulations are developed to evaluate the substitutability among spectrum bands to assist firms as well as policymakers in assessing candidate bands for use in a DSA system. For risk management, the project employs real options analysis to develop a set of risk measures and mitigation strategies for technical and financial risk to assist secondary users in DSA systems. This work will help policymakers develop better guidelines for the industry. It will also help firms seeking to use DSA technologies reason more clearly about which technical and financial choices are best and why, providing guidelines for growth and job creation. The expected outcomes of this project will include a set of tools that will enable entrants into a secondary spectrum market to make decisions as well as for policy makers to evaluate the factors that may influence their regulatory guidelines in order to promote viable DSA markets.

动态频谱接入（DSA）技术已经提出和研究了15年，但目前只有一些相对实验性的系统在运行。本研究探讨了DSA的一些基本但尚未探索的技术经济方面，如果这些系统要实现商业现实，这些方面至关重要。一个主要的推力是探索这些系统可能使用的不同频段如何相互替代。另一个主要问题是，考虑使用DSA技术的公司如何管理其中固有的技术和财务风险。为了实现这一目标，基于数学模型和基于代理的模拟开发了可替代性评分，以评估频谱带之间的可替代性，以帮助公司和政策制定者评估用于DSA系统的候选频段。在风险管理方面，该项目采用实物期权分析，为技术和财务风险制定一套风险措施和缓解战略，以协助DSA系统的二级用户。这项工作将有助于政策制定者为该行业制定更好的指导方针。它还将帮助寻求使用DSA技术的公司更清楚地了解哪种技术和财务选择是最好的，以及为什么，为增长和创造就业提供指导。该项目的预期成果将包括一套工具，这些工具将使进入二级频谱市场的人能够做出决策，并使政策制定者能够评估可能影响其监管准则的因素，以促进可行的DSA市场。
