Collaborative Research: SII-NRDZ: POWDER-RDZ - Spectrum sharing in the POWDER platform

POWDER-RDZ项目研究在实验或测试系统与现有频谱用户之间以及多个实验系统之间共享电磁（射频）频谱的方法。该研究团队将为位于犹他州盐湖城的POWDER测试平台（NSF“先进无线研究平台”项目的一部分）部署和评估一个原型自动频谱共享管理系统。目前，频谱接入方面的挑战对无线试验台的实验和测试造成了重大限制。为了安全访问额外的频率而进行的自动频谱共享——超出专门为测试保留的频率——将放松这些限制，从而提高国家进行无线研究和开发的能力。增加这一容量将有助于加速美国通信行业的增长和全球领导地位，加强对无线系统的学术研究，并使雷达、公共安全和国防等其他依赖频谱的部门受益。作为国家无线电动态区域概念的先驱，该项目将帮助未来的联邦/非联邦频谱共享安排确保频谱共享不会对政府用户产生负面影响。POWDER-RDZ团队将为先进的无线通信设计、开发端到端无线电动态区（RDZ）并进行原型设计。他们将通过执行频谱共享实验和对产生的工件进行实地研究来验证其功能。该项目使用现有的POWDER移动和无线测试平台作为RDZ的物理基础设施。POWDER现有的无线电和其他设备支持频谱共享实验，并提供RDZ所需的部分射频传感功能。该项目将设计和开发一个模块化区域管理系统（ZMS）来管理、控制和监测RDZ的各个方面。该项目计划与POWDER以外的用户进行频谱共享实验。实验可能包括RDZ对联邦、非联邦和商业频谱的共享访问，例如与商业移动运营商共享粗粒度和细粒度频谱以及与气象雷达共享频谱。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

The POWDER-RDZ project investigates ways to share the electromagnetic (radio-frequency) spectrum between experimental or test systems and existing spectrum users, and between multiple experimental systems. This research team will deploy and evaluate a prototype automatic spectrum sharing management system for the POWDER testbed in Salt Lake City, Utah (part of the NSF’s “Platforms for Advanced Wireless Research” program). Spectrum access challenges currently create significant constraints on experimentation and testing at wireless testbeds. Automatic spectrum sharing for safe access to additional frequencies – beyond the frequencies reserved exclusively for testing – will relax these constraints and thus increase the nation’s capacity to conduct wireless research and development. Increasing this capacity will help accelerate growth and global leadership of the US communications industry, strengthen academic research into wireless systems, and benefit other spectrum-dependent sectors such as radar, public safety, and national defense. As a pathfinder for the National Radio Dynamic Zone concept, the project will help future federal/non-federal spectrum sharing arrangements assure that spectrum sharing does not negatively impact government users. The POWDER-RDZ team will design, develop, and prototype an end-to-end radio dynamic zone (RDZ) for advanced wireless communication. They will validate its functionality by performing spectrum sharing experiments and field studies on the resulting artifact. The project uses the existing POWDER mobile and wireless testbed as the physical infrastructure of the RDZ. POWDER’s existing radios and other equipment supports the spectrum sharing experiments and provides part of the RF sensing functionality needed by the RDZ. The project will design and develop a modular zone management system (ZMS) to manage, control and monitor all aspects of the RDZ. The project plans to conduct experiments on spectrum sharing with users outside of POWDER. Experiments potentially include RDZ shared access to federal, non-federal, and commercial spectrum, such as coarse- and fine-grained spectrum sharing with a commercial mobile operator and spectrum sharing with a weather radar.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
