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

这项小型企业技术转让（STTR）第一阶段项目将展示近期创新动态频谱接入（DSA）技术的技术和商业可行性，以有效地与传统联邦系统共享频谱资源。不断增长的频谱需求，以及多年来对DSA等创新无线技术日益增长的监管支持，提供了一个独特的机会，展示频谱共享方法和技术如何通过寻找更有效地使用频谱的方法，从稀缺中获得丰富。本研究的目的是量化成本/收益权衡，并验证可与联邦用户共存的基于传感、地理定位和混合宽带系统的监管和系统要求。该项目将包括技术和经济建模以及几种基于策略的dsa系统配置的模拟，这些系统配置在选定的联邦频段的各种场景下，目前正在进行潜在重新分配的监管审查。它将创建详细的频谱共享系统设计文档，其中包括全面的新进入者和现有用户需求、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方面的多重效益。通过允许新系统和现有系统共存的成熟方法，实现频谱共享可将过渡过程加快5至10年。支持dsa的频谱共享在地理和时间基础上大大增加了宽带无线系统的总体容量。这项技术还在适当的情况下促进联邦频段的频段清理，并在联邦现任人员搬迁成本过高或不可行的情况下最大限度地提高频谱接入。这避免了从拍卖收益中重新分配资金，以支付联邦政府在规划、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免许可、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。当联邦系统必须搬迁时，DSA允许他们在其他频段获得同等或改进的频谱接入。该项目将通过确定利益相关者需求和具有成本效益的解决方案，极大地提高对支持dsa的频谱共享的理解。它将通过生成不同DSA方法的成本数据来证明这些功能是可行的，并且可以让运营商、监管机构和现有运营商了解成本是否与带宽收益相一致。

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.
