由于移动的和可穿戴设备以及诸如虚拟/增强现实和超高清视频流之类的新兴应用的快速增长，下一代无线网络必须满足不断增长的移动的流量需求。当今的无线网络（诸如在2.4/5千兆赫（GHz）频谱下操作的传统WiFi网络）在无线链路上提供每秒数千兆比特的数据速率方面存在不足。近年来，毫米波频谱（特别是未经许可的60 GHz频谱）的使用已被证明可以实现每链路每秒7千兆比特的数据速率。尽管有潜力，但在可靠性、移动性、干扰和覆盖范围方面仍存在许多突出的挑战，需要解决这些挑战，以实现企业级毫米波网络。该项目的主要目标是设计一个毫米波网络和传感测试平台，使用可重构的60 GHz软件无线电。该测试平台将是一个最先进的基础设施，将促进下一代高速无线网络的研究、教育和开发。该多链路测试平台具有电子波束形成功能、集成的相控天线阵列、多现场可编程门阵列处理功能以及物理和媒体访问控制层模块的开发，将能够对覆盖范围进行详细测量和表征，60 GHz无线局域网中的移动性和干扰。从研究中获得的见解将用于设计智能网络部署策略，这些策略可以在存在室内移动性和不可预测的链路中断的情况下提供可靠的覆盖。创新的多级码本设计和低复杂度的到达方向（DoA）为基础的信道估计技术将开发灵活和节能的波束形成。基于角分多址（ADMA）的干扰感知多址接入协议将进行研究，其中来自不同角度的用户通过波束成形在角度域中分离，来自相同角度簇的用户可以通过正交编码同时接入信道。此外，基于协调多点（CoMP）和跨技术协调的中断缓解技术将被研究，以保证在阻塞和移动性的存在下的可靠连接。毫米波测试平台将用于设计低成本，高精度的射频传感技术，用于辅助生活设施中的医疗保健和活动传感，智能空间中无处不在的远程交互，以及无障碍计算应用，包括聋人和重听用户的自动手语识别。将探索和评估通过网络移动性进一步增强网络和感知性能的解决方案。

The next generation of wireless networks must meet the ever-increasing mobile traffic demand due to the rapid growth of mobile and wearable devices and newly emerging applications such as virtual/augmented reality and ultra high-definition video streaming. Today's wireless networks such as legacy WiFi networks operating at 2.4/5 Gigahertz (GHz) spectrum fall short in providing multiple gigabit per second data rates on wireless links. In recent years, the use of millimeter-wave spectrum (especially the unlicensed 60 GHz spectrum) has been shown to achieve 7 gigabits per second per-link data rates. In spite of the potential, there are many outstanding challenges in terms of reliability, mobility, interference and coverage that need to be addressed to enable enterprise-grade millimeter-wave networks. The main objective of this project is to design a millimeter-wave networking and sensing testbed using reconfigurable 60 GHz software radios. The testbed will be a state-of-the-art infrastructure that will foster research, education and development of the next generation high-speed wireless networks.With the electronic beamforming capabilities, integrated phased antenna array, multi-Field-Programmable Gate Array processing functionality and development of the Physical and Medium Access Control layer modules, the multi-link testbed will enable detailed measurements and characterization of coverage, mobility and interference in 60 GHz Wireless Local Area Networks. The insights gained from the study will be used to devise intelligent network deployment strategies that can provide reliable coverage in the presence of indoor mobility and unpredictable link outages. Innovative multi-level codebook design and low-complexity Direction of Arrival (DoA)-based channel estimation techniques will be developed for agile and energy-efficient beamforming. Interference-aware multiple access protocols based on Angular Division Multiple Access (ADMA) will be investigated where users from different angles are separated in the angular domain through beamforming and users from the same angular cluster may access the channel simultaneously via orthogonal coding. Additionally, outage mitigation techniques based on Coordinated Multi-Point (CoMP) and cross-technology coordination will be studied to guarantee reliable connectivity in the presence of blockage and mobility. The millimeter-wave testbed will be used to design low-cost, highly-accurate radio frequency sensing techniques for healthcare and activity sensing in assisted living facilities, ubiquitous remote interaction in smart spaces, and accessible computing applications including automatic sign language recognition for the deaf and hard of hearing users. Solutions further enhancing the networking and sensing performance through network mobility will be explored and evaluated.
