This Small Business Technology Transfer (STTR) Phase I project will characterize the interference environment of outdoor unlicensed 900 and 2400 MHz wireless networks used for public safety and energy management. It will also develop a proof of concept and test innovative interference minimizing smart antenna prototypes to restore operations and improve performance of public safety networks. Private wireless broadband networks, deployed by municipalities and utilities are used for such functions as public safety, public Internet access, and energy and water management. These networks are experiencing dramatic growth in both size and number. This growth, along with expanding enterprise and consumer use of overlapping devices and Wireless Local Area Networks (WLANs), continue to exacerbate performance reducing interference problems. This interference has forced many municipalities to double their investments in infrastructure equipment or to increase transmitter power to overcome interference, thus producing more interference for overlapping systems.If successful the use of this antenna in the proposed band will help first responders save lives. For example, interactive live video, voice and vitals monitoring allow physicians to interact with disaster victims and their caregivers at the scene and during transport. These and other applications such as GPS enabled emergency response vehicle and personnel tracking and fuel-efficient dispatch require large amounts of data to be delivered over reliable wireless networks. This unique smart antenna technology will help insure that private municipal wireless networks provide reliable high data rates that continue to meet performance goals as the frequencies they use become more crowded.

这个小型企业技术转让(STTR)第一阶段项目将描述用于公共安全和能源管理的室外未经许可的900 MHz和2400 MHz无线网络的干扰环境。它还将开发概念验证并测试将干扰降至最低的创新智能天线原型，以恢复运营并提高公共安全网络的性能。市政和公用事业部门部署的专用无线宽带网络用于公共安全、公共互联网接入以及能源和水管理等功能。这些网络在规模和数量上都经历了戏剧性的增长。这种增长，加上企业和消费者对重叠设备和无线局域网(WLAN)的使用不断扩大，继续加剧了降低干扰的性能问题。这种干扰迫使许多市政当局在基础设施设备上的投资增加一倍，或者增加发射机功率以克服干扰，从而对重叠的系统产生更多干扰。如果成功，在拟议的频段使用这种天线将有助于急救人员挽救生命。例如，交互式实时视频、语音和生命体征监测使医生能够在现场和运输过程中与灾民和他们的护理人员互动。这些应用程序和其他应用程序，如启用GPS的应急响应、车辆和人员跟踪以及节油调度，都需要通过可靠的无线网络传输大量数据。这种独特的智能天线技术将有助于确保专用市政无线网络提供可靠的高数据速率，并在它们使用的频率变得更加拥挤时继续满足性能目标。
