This EARS (Enhancing Access to the Radio Spectrum) program was founded in response to the 2010 Presidential Memorandum on Unleashing the Wireless Broadband Revolution mandated by Congress as part of the National Broadband Plan. It was referenced in 2010 State of the Union and later on the Middle Class Tax Relief and Job Creation Act of 2012 (More than 1/3 of the bill deals with radio spectrum), the PCAST 2012 Report [President's Council of Advisors on Science and Technology] (which calls for vastly increased use of spectrum sharing) and the 2013 Presidential memo (Expanding America's Leadership in Wireless Innovation). The aim of this program is to identify bold new concepts with the potential to contribute to significant improvements in the efficiency of radio spectrum utilization, protection of passive sensing services, and in the ability for traditionally underserved Americans to benefit from current and future wireless-enabled goods and services. The impact is large on the economics of the Nation as seen on the last FCC bidding of 65MHz of the spectrum for over $45 billion early in 2015. It will enable access to science, engineering, industry, civilian and military users of the RF spectrum.This project will analyze the magnitude of spectrum scarcity as it relates to the optimization of spectrum utilization. The cellular industry has been asking for more spectrum for mobile broadband by calling it a "Supply" to support higher "Demand" of mobile data services. Higher amount of spectrum can surely support data-centric services more efficiently. However, other variables of Wireless Broadband Eco-systems can lower the burden on existing cellular infrastructure and they can collectively play a role of "substitute" for more spectrum. The PI's preliminary model (based on System Dynamics techniques) already showed that the need for more spectrum could be lowered by making efficient use of existing network infrastructure (e.g. Wi-Fi Offloading). To make the existing model comprehensive and future-proof, they plan to expand it by adding economic parameters like auction data and recently emerged technical parameters like Spectrum Re-farming, Small Cells, and LTE deployment in unlicensed bands. This research will also incorporate economic studies and drivers to better understand the efficiency at which the new spectrum is being utilized by cellular operators and how it affects their plans to deploy data offloading techniques on unlicensed frequencies. The proposed project is not limited to "research" activities but it includes "development" phase as well; the research part will allow them to define the mathematical relationships among the technical and economic variables and the development part will produce a working and interactive model of mobile broadband eco-system to demonstrate the effects of various technical and economic variables on spectrum allocation. The project outcome not only will test the Spectrum Scarcity hypotheses but will also provide future projections for spectrum utilization and will trigger recommendations to government and regulatory bodies for sufficient allocation of spectrum.

该耳朵（增强无线电频谱的访问）计划是根据2010年总统备忘录释放国会作为国家宽带计划的一部分的无线宽带革命的响应而建立的。它在2010年国际电联的2012年中产阶级税收减免和创造就业法案（超过1/3涉及无线电频谱），PCast 2012 2012报告[总统科学技术顾问委员会]（呼吁大大增加频谱共享的使用）和2013年美国总统纪念馆（扩大无线领导力的领导力）。该计划的目的是确定大胆的新概念，有可能为无线电频谱利用率的效率，被动传感服务的保护以及传统上服务不足的美国人从当前和未来的无线支持商品和服务中受益的能力做出重大改善。正如2015年初以超过450亿美元的超过450亿美元的上一次FCC竞标所示，对国家经济的影响很大。它将能够获得RF Spectrum的科学，工程，工业，工业，工业，平民和军事用户的访问。该项目将分析光谱稀缺性的范围。蜂窝行业一直在要求更多的移动宽带寻求更多范围，以支持移动数据服务的更高“需求”。较高的频谱肯定可以更有效地支持以数据为中心的服务。但是，无线宽带生态系统的其他变量可以降低现有的蜂窝基础设施的负担，并且可以集体发挥“替代”的作用。 PI的初步模型（基于系统动力学技术）已经表明，通过有效利用现有网络基础架构（例如Wi-Fi卸载），可以降低对更多频谱的需求。为了使现有的模型全面且不适合未来，他们计划通过添加诸如拍卖数据之类的经济参数以及最近出现的技术参数来扩展它，例如频谱重新购买，小单元和LTE部署在未经许可的频段中。这项研究还将纳入经济研究和驱动因素，以更好地了解细胞操作员利用新频谱的效率，以及它如何影响他们的计划，以在无执照的频率上部署数据卸载技术。拟议的项目不仅限于“研究”活动，但也包括“开发”阶段。研究部分将使他们能够定义技术和经济变量之间的数学关系，而开发部分将产生移动宽带生态系统的工作和互动模型，以证明各种技术和经济变量对频谱分配的影响。项目结果不仅可以检验频谱稀缺假设，还将为未来的频谱利用提供预测，并将触发政府和监管机构的建议，以充分分配频谱。
