The radio frequency spectrum that can be used for wireless communications is a finite but extremely valuable resource. With the proliferation of new wireless applications, the use of the radio spectrum has intensified to the point that there is a critical need of new spectrum-sharing mechanisms and improved spectrum policies. In the recent NSF workshop report on Enhancing Access to the Radio Spectrum (EARS), several Grand Challenges are outlined for the research community to realize the vision of enhancing the efficiency of future spectrum use. One of the Grand Challenges is harmonious co-existence of heterogeneous wireless technologies, with the goal of accommodating multiple wireless access technologies that would operate in the same radio spectrum band. The proposed research addresses the co-existence Grand Challenge by investigating the following three tightly-coupled research areas: (1) Coexistence between Wi-Fi and cellular on unlicensed bands; (2) Coexistence of radar and cellular on radar bands; and (3) New software and hardware testbeds for coexistence. The proposed research activities will catalyze broader impact activities in multiple dimensions: (1) improving and influencing future spectrum policies by the government; (2) transitioning technologies to industry; (3) developing new education materials and software tools to be used in classroom; and (4) attracting and engaging students, particularly female and under-represented students in spectrum-sharing research activities. The proposed research addresses the coexistence Grand Challenge by tackling two of the most popular wireless services (Wi-Fi and cellular) on radio spectrum bands. The proposed research on coexistence between Wi-Fi and cellular on unlicensed bands takes a new approach to resolve the potential conflict between the two technologies by shifting focus to the user side and maximizing total user satisfaction. The research on coexistence between radar and cellular on the radar bands explores the largely untapped radar spectrum that the government is considering for coexistence. The proposed architecture goes well beyond the current Spectrum Access Server concept by considering some unique characteristics and challenges associated with radar systems. New software and hardware testbeds will be developed to offer the much-needed facility for the research community for validation and experimentation of new approaches for coexistence. The outcomes of the research will be shared with government and regulatory agencies to help improve spectrum policies, which are crucial to enable the proposed new coexistence technologies to make impacts in the real world.

可用于无线通信的射频频谱是有限但极为宝贵的资源。 随着新无线应用程序的扩散，无线电频谱的使用已加剧，以至于至关重要的是需要新的频谱共享机制和改进的频谱策略。在最近的NSF研讨会上有关增强无线电频谱（EARS）访问权限的报告中，概述了研究社区实现提高未来光谱使用效率的愿景的一些巨大挑战。 巨大的挑战之一是异质无线技术的和谐共存，其目的是容纳多种无线访问技术，这些技术将在同一无线电频谱频段中运行。拟议的研究通过研究以下三个紧密耦合的研究领域来解决共存大挑战：（1）在未经许可带上Wi-Fi和Cellular之间的共存； （2）雷达和细胞在雷达带上共存； （3）新软件和硬件测试床以共存。 拟议的研究活动将在多个方面促进更广泛的影响活动：（1）改善和影响政府未来的频谱政策； （2）过渡到工业的技术； （3）开发新的教育材料和软件工具，要在课堂上使用； （4）吸引和吸引学生，尤其是女性和代表性不足的学生在谱系共享研究活动中。 拟议的研究通过在无线电频谱频段上解决两项最受欢迎的无线服务（Wi-Fi和蜂窝），以解决共存的盛大挑战。关于无牌带上Wi-Fi和蜂窝之间共存的拟议研究采用了一种新方法，通过将重点转移到用户方并最大程度地提高用户满意度来解决这两种技术之间的潜在冲突。雷达带上雷达和细胞之间的共存的研究探讨了政府正在考虑共存的很大程度上未开发的雷达谱。通过考虑与雷达系统相关的一些独特特征和挑战，所提出的架构远远超出了当前的频谱访问服务器概念。将开发新的软件和硬件测试床，为研究社区提供急需的设施，以验证和实验新方法的共存方法。 该研究的结果将与政府和监管机构共享，以帮助改善频谱政策，这对于使拟议的新共存技术能够在现实世界中产生影响至关重要。
