Wireless communications and networks have experienced exponential growth in data rates and traffic over the past decade, driven by the ever-increasing density of mobile devices, multimedia services and data requirements. The resulting electromagnetic spectrum below 60-GHz has become extremely overcrowded, even with advanced spectrum-efficient modulation formats and spatially diverse multiple-input multiple-output (MIMO) techniques. At present, the sub-millimeter-wave (sub-mm-Wave) electromagnetic spectrum between 300 GHz and 850 GHz is largely unassigned and provides a unique opportunity for more efficient utilization. This will avoid further crowding the currently heavily used spectrum and significantly enhance data rates to tens of Gb/s. This project seeks to demonstrate such a fundamentally new platform towards spectral-efficient and energy-efficient wireless communications with embedded security. Due to the inherent atmospheric attenuation, the sub-mm-Wave communication distance has been limited to within 50 m. Thus, this project proposes network configurations of sub-mm-Wave point-to-point links to enable secured spatial coverage over longer distances and larger areas. There are two distinct differences of the sub-mm-Wave links compared to traditional wireless networks: the directivity of the sub-mm-Wave links and the possibility for a transmitter to connect to multiple receivers through adaptive electronic beam-steering and beam-forming. The beam-forming with narrow beam-width removes broadcasting and avoids interference, enabling much simpler network operation to approach the theoretical upper limits of network information capacity. The project seeks to demonstrate the modular sub-mm-Wave link hardware to achieve the above goal. The proposed research will be complemented with an integrated education and outreach program. This includes diversity recruitment, mentoring and retention, hands-on curriculum development, minority high-school and undergraduate training, and public outreach. The cross-layer scientific and education provides a new platform at the interface of hardware, software, and networks in next-generation wireless communication networks.This project will develop a spectrally dense, high-data-rate, 650-GHz photonic wireless communications platform in a diamond mesh network, while explicitly addressing network security and energy efficiency in the architecture. The collaborative research spans across the physical layer, the network layer, and the software layer, addressing cross-layer issues in the fundamental architecture. The proposed research consists of three thrust areas. In Thrust I, the project will examine a modular photonic sub-mm-Wave link, based on a chip-scale photomixer driven by an optical frequency comb recently developed by the team. This enables high-power spectrally dense, 80 Gb/s sub-mm-Wave transmission. In Thrust II, the project will examine a photonic sub-mm-Wave 80 Gb/s testbed, implemented with an adaptive smart antenna array. Beam-steering and beam-forming will enable simultaneously a directional line-of-sight (LoS) link and a non-line-of-sight (NLoS) link, with the former establishing a spectrally efficient channel with less inter-symbol and inter-channel interference. The latter mitigates medium non-idealities such as interference, shadowing, and multi-path effects. In Thrust III, the project will study the capacity of sub-mm-Wave communication networks and explore the design of near-optimal efficient and secure algorithms. Enabled by the intrinsic directivity and beam-forming capabilities of our sub-mm-Wave link, the project will advance the possibility of unconditional security in the wireless backhaul network through physical layer security algorithms.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.

在过去十年中，无线通信和网络经历了数据速率和业务的指数增长，这是由移动的设备、多媒体服务和数据需求的不断增加的密度所驱动的。由此产生的低于60 GHz的电磁频谱已经变得非常拥挤，即使使用先进的频谱效率调制格式和空间多样的多输入多输出（MIMO）技术。目前，300 GHz至850 GHz之间的亚毫米波（sub-mm-Wave）电磁频谱在很大程度上未分配，为更有效的利用提供了独特的机会。这将避免目前大量使用的频谱进一步拥挤，并将数据速率显著提高到数十Gb/s。该项目旨在展示这样一个全新的平台，以实现具有嵌入式安全性的频谱效率和节能无线通信。由于固有的大气衰减，亚毫米波通信距离已被限制在50 m以内。因此，该项目提出了亚毫米波点对点链路的网络配置，以实现更长距离和更大区域的安全空间覆盖。与传统的无线网络相比，亚毫米波链路有两个明显的区别：亚毫米波链路的方向性和发射机通过自适应电子波束转向和波束成形连接到多个接收机的可能性。窄波束的波束形成消除了广播，避免了干扰，使网络操作更加简单，接近网络信息容量的理论上限。该项目旨在展示模块化亚毫米波链路硬件，以实现上述目标。拟议的研究将辅之以综合教育和外联方案。这包括多样性招聘，辅导和保留，动手课程开发，少数民族高中和本科生培训，以及公共宣传。跨层的科学和教育为下一代无线通信网络提供了硬件、软件和网络接口的新平台，该项目将在钻石网状网络中开发频谱密集、高数据速率、650-GHz的光子无线通信平台，同时在架构中明确解决网络安全和能源效率问题。协作研究跨越物理层、网络层和软件层，解决基础架构中的跨层问题。拟议的研究包括三个重点领域。在Thrust I中，该项目将研究模块化光子亚毫米波链路，该链路基于由该团队最近开发的光频梳驱动的芯片级光混合器。这实现了高功率频谱密度的80 Gb/s亚毫米波传输。在Thrust II中，该项目将研究一个光子亚毫米波80 Gb/s测试平台，该平台采用自适应智能天线阵列。波束控制和波束成形将同时实现定向视线（LoS）链路和非视线（NLoS）链路，其中前者建立具有较少符号间和信道间干扰的频谱高效信道。后者减轻了介质非理想性，例如干扰、阴影和多径效应。在Thrust III中，该项目将研究亚毫米波通信网络的容量，并探索接近最佳的高效和安全算法的设计。通过我们的亚毫米波链路的固有方向性和波束形成能力，该项目将通过物理层安全算法提高无线回程网络无条件安全的可能性。该奖项反映了NSF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。
