This Small Business Innovation Research (SBIR) Phase II project targets significantly increased throughputs and distances for broadband access over the existing copper landline infrastructure at low cost. In particular, the technology being developed offers advantages in interference-dominated and in suburban/rural environments. In the USA alone there are many millions of households that are currently out-of-reach of broadband access, where there are typically multiple copper landlines available, and the global demand for such solution is significantly higher. For these underserved subscribers, this innovative extended-reach solution represents the only low-cost broadband access alternative to costly, inefficient satellite coverage. While existing Digital-Subscriber-Line (DSL) solutions are not specified to provide broadband access at very long distances, the company?s novel solution greatly increases the achievable distances and allows broadband rates (1Mbps) to be delivered at extended ranges, as demonstrated in Phase 1 of this project. The technology combines innovative signal-processing algorithms with novel digital implementation architectures to allow for high-performance reduced-complexity and low current-consumption implementations. The broader impact and commercial potential of this project are in enabling affordable broadband service to the many households, which are currently out of the reach of broadband access, and in enhancing the performance of other copper-based applications. The technology will enable telco providers to better compete in areas where cable service exists, and can enhance existing solutions for copper-based backhaul, thereby helping service providers with the growing problem of backhaul bottlenecks associated with increased wireless traffic. The growing demand for solutions of this type has the potential to generate annual revenues on the order of $50M, representing a great business opportunity. Societal benefits include providing broadband service to previously-unreachable homes, thus allowing them to engage in remote education, e-commerce, and telecommuting, with all of the advantages that these entail. Ongoing collaborative research with local universities is serving to steer academic research in this field towards the actual needs and interests expressed by service providers, thus advancing the related fields in communication theory and circuitry design and involving students in this research.

该小型企业创新研究 (SBIR) 第二阶段项目的目标是通过现有铜质固定线路基础设施以低成本显着提高宽带接入的吞吐量和距离。特别是，正在开发的技术在干扰为主的环境和郊区/农村环境中具有优势。仅在美国，就有数百万家庭目前无法获得宽带接入，而这些家庭通常有多条铜质固定电话，而全球对此类解决方案的需求要高得多。对于这些服务不足的用户来说，这种创新的延伸范围解决方案是替代昂贵、低效的卫星覆盖的唯一低成本宽带接入替代方案。虽然现有的数字用户线路 (DSL) 解决方案并未指定提供超长距离宽带接入，但该公司的新颖解决方案极大地增加了可实现的距离，并允许在更远的范围内提供宽带速率 (1Mbps)，如图所示在该项目的第一阶段。该技术将创新的信号处理算法与新颖的数字实现架构相结合，以实现高性能、降低复杂性和低电流消耗的实现。该项目更广泛的影响和商业潜力在于为目前无法获得宽带接入的许多家庭提供负担得起的宽带服务，并提高其他铜基应用的性能。该技术将使电信提供商能够在有线服务存在的领域更好地竞争，并可以增强现有的铜缆回程解决方案，从而帮助服务提供商解决与无线流量增加相关的日益严重的回程瓶颈问题。对此类解决方案不断增长的需求有可能产生约 5000 万美元的年收入，代表着巨大的商机。社会效益包括为以前无法​​到达的家庭提供宽带服务，从而使他们能够参与远程教育、电子商务和远程办公，并享受这些带来的所有优势。与当地大学正在进行的合作研究正在引导该领域的学术研究转向服务提供商表达的实际需求和兴趣，从而推进通信理论和电路设计的相关领域并让学生参与这项研究。
