This Small Business Technology Transfer (STTR) Phase I project seeks to implement a Robust Emergency Data (RED) Link. Recent breakthroughs in wireless communication collectively referred to as multiple-input multiple-output (MIMO) technology exploit multiple "dimensions" in space, frequency, time, antenna polarization, and antenna radiation patterns to create parallel or multiplexed channels. This project aims to investigate an aspect of MIMO: exploiting near-field components in the reactive-field region close to transmitting antennas. This project explores novel near-field MIMO to exploit low-frequency RF spectrum as a medium for short-range, robust, bidirectional wireless communication links. Long-wavelength ( 300m) low-frequency (1 MHz) signals tend to be more penetrating, more multipath resistant, and more robust in cluttered environments than conventional short wavelength high-frequency links. The proposed technique provides a novel bandwidth-enhanced MIMO communication method and a robust diversity communication method which will be virtually free from severe fading. The anticipated result is a RED Link capable of supporting two-way voice and telemetry even in high multipath environments. Operating within FCC Part 15 constraints, the system will function out to ranges of 50m or more.The broader impact/commercial potential of this project includes enhancing understanding of near-field wireless systems, as well as uses spanning multiple emergency communications applications. Approximately 100 firefighters die in the line of duty each year. Improved communications systems could save some of these lives. Every year, workers die in hazardous environments, like mines and chemical plants because rescuers are unable to contact or locate them. Similarly, about 10% of American casualties in combat are caused by "friendly" fire. A system that can provide robust communications for warfighters, particularly in urban combat, could prevent some of these casualties. Finally, near-field communications (NFC) is an emerging RF technology with the potential to revolutionize short-range, high-security data links. The proposed effort could dramatically improve the capacity of these wireless links

这个小型企业技术转让（STTR）第一阶段项目旨在实施一个强大的应急数据（RED）链接。统称为多输入多输出（MIMO）技术的无线通信中的最新突破利用空间、频率、时间、天线极化和天线辐射模式中的多个“维度”来创建并行或复用信道。本项目旨在研究MIMO的一个方面：利用发射天线附近的无功场区域中的近场分量。该项目探索新型近场MIMO，以利用低频RF频谱作为短距离，鲁棒，双向无线通信链路的介质。与传统的短波长高频链路相比，长波长（300 m）低频（1 MHz）信号往往更具穿透力，更能抵抗多径，并且在杂波环境中更鲁棒。所提出的技术提供了一种新的带宽增强的MIMO通信方法和一个强大的分集通信方法，这将几乎没有严重的衰落。预期的结果是一个红色链接能够支持双向语音和遥测，即使在高多径环境。该系统在FCC Part 15限制范围内运行，将在50米或更远的范围内发挥作用。该项目更广泛的影响/商业潜力包括提高对近场无线系统的理解，以及跨越多种应急通信应用的用途。每年大约有100名消防员在执行任务时死亡。改善通信系统可以挽救其中一些生命。每年都有工人在危险的环境中死亡，如矿山和化工厂，因为救援人员无法联系或找到他们。同样，大约10%的美国人在战斗中的伤亡是由“友军”炮火造成的。一个可以为作战人员提供强大通信的系统，特别是在城市作战中，可以防止一些伤亡。最后，近场通信（NFC）是一种新兴的射频技术，有可能彻底改变短距离、高安全性的数据链路。拟议的努力可以大大提高这些无线链路的容量
