The demand for wireless services continues to increase rapidly, and society has come to rely on the availability of wireless services everywhere and at all times. Conventional wireless services rely on communications at radio frequencies below 5 GHz. These frequency bands are heavily used, and future systems will not be able to meet all demands if operated only with these existing technologies. Recent work has created electronic devices able to generate communications signals at higher frequencies, from 30-300 GHz, which is known as the 'millimeter wave' band. Communications links in these bands have the promise of delivering enormous wireless capacity, but these links behave somewhat more like beams of light than conventional radio communications they can be directional and are easily blocked by objects and by people's bodies. This project investigates the development of wireless networks that can effectively use these links. This exploration is through a collaboration between Virginia Tech (VT), Trinity College Dublin (TCD), and Queen's University Belfast (QUB). The project explores many aspects of these millimeter wave communication systems, with a focus on improving services in population-dense environments like stadiums, theaters, and transportation hubs. The work will influence the development of future cellular communications systems; these systems are critical infrastructure for society and enablers for economic growth. The technical work of the project will be accomplished through six research thrusts. A network architecture for exploiting millimeter wave communication links while maintaining control of the network via a conventional cellular network will be developed and assessed. Making new measurements of millimeter wave channels will enable the creation of more accurate mathematical models of millimeter wave communication links. The allocation of resources to these communication links in ways that preserve the perceived performance of user applications in the presence of uncertainty regarding link conditions will be explored. The capacity of these densely deployed networks will be analyzed through the application of hybrid analytical-simulative techniques. New models of infrastructure sharing to enable this millimeter wave infrastructure to be shared among cellular operators will be developed and studied. Finally, the developed architecture will be assessed in a holistic way by developing end-to-end simulations and proof-of-concept demonstrations using commercial hardware.

对无线服务的需求持续快速增长，并且社会已经开始依赖于随时随地的无线服务的可用性。传统的无线服务依赖于低于5GHz的无线电频率的通信。这些频带被大量使用，如果仅使用这些现有技术，未来的系统将无法满足所有需求。最近的工作创造了能够以更高频率产生通信信号的电子设备，从30-300 GHz，这被称为“毫米波”波段。这些频段的通信链路有望提供巨大的无线容量，但这些链路的行为比传统的无线电通信更像光束它们可以是定向的，很容易被物体和人体阻挡。本项目研究能够有效利用这些链路的无线网络的开发。这项探索是通过弗吉尼亚理工大学（VT），Trinity学院都柏林（TCD）和女王大学贝尔法斯特（QUB）之间的合作。该项目探索了这些毫米波通信系统的许多方面，重点是改善体育场，剧院和交通枢纽等人口密集环境中的服务。这项工作将影响未来蜂窝通信系统的发展;这些系统是社会的关键基础设施和经济增长的推动力。该项目的技术工作将通过六个研究重点来完成。将开发和评估一种网络架构，用于利用毫米波通信链路，同时通过传统的蜂窝网络保持对网络的控制。 对毫米波信道进行新的测量将能够创建更精确的毫米波通信链路数学模型。将探讨在链路条件存在不确定性的情况下，以保持用户应用程序的感知性能的方式将资源分配给这些通信链路。这些密集部署的网络的能力将通过混合分析模拟技术的应用进行分析。将开发和研究基础设施共享的新模式，以使这种毫米波基础设施能够在蜂窝运营商之间共享。最后，将通过使用商业硬件开发端到端模拟和概念验证演示来全面评估所开发的架构。
