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.

在过去的十年中，无线通信和网络在数据速率和流量上的指数增长，这是由于移动设备，多媒体服务和数据要求的不断增长的驱动。即使采用先进的频谱调制格式和空间多样的多输入多输出（MIMO）技术，即使采用的电磁光谱也已经变得极为拥挤。目前，300 GHz和850 GHz之间的亚毫米波（亚米波）电磁光谱在很大程度上没有分配，并为更有效的利用提供了独特的机会。这将避免进一步拥挤当前使用的频谱，并将数据速率显着提高至数十GB/s。该项目旨在证明具有嵌入式安全性的频谱效率和节能无线通信的根本新平台。由于固有的大气衰减，次级摩托车的通信距离已限制在50 m以内。因此，该项目提出了子-MM波点对点链接的网络配置，以在更长的距离和较大区域内实现有安全的空间覆盖范围。与传统的无线网络相比，亚MM波链路有两个明显的差异：亚MM波链路的方向性以及发射机通过自适应电子束传导和梁形成连接到多个接收器的可能性。具有窄梁宽度的光束形成可以消除广播并避免干扰，从而使网络操作能够接近网络信息能力的理论上限制。该项目旨在演示模块化的子-MM波链路硬件，以实现上述目标。拟议的研究将与综合教育和外展计划相辅相成。这包括多样性招聘，指导和保留，动手课程发展，少数民族高中和本科培训以及公共宣传。跨层科学和教育在下一代无线通信网络中的硬件，软件和网络的界面上提供了一个新的平台。本项目将在钻石网络中开发一个频谱密集的，高数据速率，650 GHz光子无线通信平台，同时明确地解决该建筑中的网络安全和能源效率。协作研究跨越了整个物理层，网络层和软件层，解决了基本体系结构中的跨层问题。拟议的研究由三个推力区域组成。在推力I中，该项目将基于由团队最近开发的光学频率梳子驱动的芯片尺度的光电量，检查模块化光子子-MM波链路。这可以使高功率频谱密集，80 GB/s sub-mm波传输。在推力II中，该项目将检查一个具有自适应智能天线阵列的光子子-MM波80 GB/S测试床。光束向导和梁形成将同时实现方向性的视线（LOS）链接和非视线（NLOS）链路，前者建立一个具有较小符号间和通道间干扰的频谱高效通道。后者减轻了媒介的非理想性，例如干扰，阴影和多路径效应。在Thrust III中，该项目将研究亚MM波通信网络的能力，并探索近距离高效且安全的算法的设计。该项目由我们的亚MM-WAVE链接的固有方向性和横梁形成能力，将通过物理层安全算法在无线逆行网络中提高无条件安全性的可能性。该奖项反映了NSF的法定任务，并通过使用基金会的知识优点和广泛影响来评估NSF的法定任务。
