STTR Phase I: Technical, Economic, and Regulatory Evaluation and Demonstration of Policy-based Dynamic Spectrum Access-Enabled Broadband Wireless Communications Networks

这个小型企业技术转让（STTR）第一阶段项目将展示近期创新的动态频谱接入（DSA）技术的技术和商业可行性，以有效地与传统的联邦系统共享频谱资源。频谱需求沿着增加，加上多年来对DSA等创新无线技术的监管支持不断增加，这为我们提供了一个独特的机会，可以展示频谱共享方法和技术如何通过找到更有效地使用频谱的方法，从稀缺中获得丰富。本研究的目标是量化的成本/效益权衡，并验证监管和系统的要求，基于传感，地理位置和混合宽带系统，可以与联邦用户共存。该项目将包括在选定的联邦频段内的各种场景下，对几种基于政策的、支持DSA的系统配置进行技术和经济建模和模拟，这些频段目前正在接受监管审查，以进行可能的重新分配。它将创建详细的频谱共享系统设计文档，其中包括全面的进入者和现任用户需求，架构和成本（包括初始测试，验证和交易成本，增量资本成本，实施成本和经常性运营成本）。最后将制定一项示范计划，实地测试最具成本效益的共享方法。该项目的更广泛影响将体现在提高频谱效率、降低成本和促进美国创新所带来的多重利益上。启用频谱共享可通过允许新系统和现有系统共存的成熟方法将过渡过程加速5到10年。在地理和时间基础上的DSA使能的频谱共享极大地增加了宽带无线系统的总体容量。该技术还在适当的情况下促进联邦频带中的频带清除，并且在联邦现任者的重新定位成本太高或不可行的情况下最大化频谱接入。这就避免了不得不将拍卖所得的资金用于联邦政府在规划、重新设计和移动每一个现有系统方面的努力。它还通过启用创新的无执照、轻型许可和其他模式，缓解了拍卖更多独家使用频谱许可证的压力。当联邦系统必须重新定位时，DSA允许它们在其他频带中获得等同或改进的频谱接入。该项目将通过确定利益相关者的要求和具有成本效益的解决方案，大大提高对DSA支持的频谱共享的理解。它将证明这些能力是可行的，并通过为不同的DSA方法生成成本数据来获得真实的收益，从而使运营商、监管机构和现有企业能够了解成本是否与带宽收益一致。

This Small Business Technology Transfer (STTR) Phase I project will demonstrate the technical and commercial feasibility of the near-term innovative Dynamic Spectrum Access (DSA) technology to efficiently share spectrum resources with legacy Federal systems. Increasing spectrum demand along with years of growing regulatory support for innovative wireless technologies like DSA presents a unique opportunity to show how spectrum sharing approaches and technologies can wring abundance from scarcity by finding ways to use spectrum more efficiently. The objectives of this research are to quantify the cost/benefit tradeoffs and validate the regulatory and system requirements for sensing-based, geo-location and hybrid broadband systems that can coexist with Federal users. The project will consist of technical and economic modeling and simulations of several policy-based, DSA-enabled system configurations under a wide range of scenarios in selected Federal bands currently under regulatory review for potential reallocation. It will create detailed spectrum sharing system design documents that include comprehensive entrant and incumbent user requirements, architectures and costs (including initial testing, validation and transaction costs, incremental capital costs, implementation costs and recurring operational costs). It will culminate with a demonstration plan to field test the most cost-effective sharing approaches. This broader impact of this project will be in the multiple benefits resulting from improving spectrum efficiency, lowering costs and fostering American innovation. Enabling spectrum sharing accelerates by 5 to 10 years the transition process through proven approaches that allow co-existence of new and incumbent systems. DSA-enabled spectrum sharing on both a geographic and temporal basis greatly increases the overall capacity of broadband wireless systems. This technology also facilitates band clearing in Federal bands, where appropriate, and maximizes spectrum access where relocation of Federal incumbents would be too costly or infeasible. This avoids having to redirect funds from auction proceeds to cover Federal government efforts in planning, redesigning and moving every existing system. It also relieves the pressure to auction more exclusive use spectrum licenses by enabling innovative unlicensed, light licensing and other models. When Federal systems must be relocated, DSA allows them to gain equivalent or improved spectrum access in other bands. This project will greatly improve the understanding of DSA-enabled spectrum sharing by identifying stakeholder requirements and cost effective solutions. It will prove that these capabilities are feasible and benefits real by producing cost data for different DSA approaches, allowing operators, regulators and incumbents to understand whether costs align with bandwidth gains.
