Wireless system performance is known to be highly dependent upon the characteristics of the environment. Despite the increasing ability of wireless devices to sense their surroundings, wireless systems have yet to fully leverage contextual data to improve performance. To this end, the Dallas-ARea Testbed for Context-Aware, Cognitive Research (DART-CARs) allows the study of wireless performance in a broad class of mobile and static environments from indoor labs to outdoor high-way speeds within a single testbed. Our hardware platform functions across many different wireless bands to enable real-time, multi-band operation. Such a first-of-its-kind infrastructure is critical for designing context-aware and cognitive algorithms that utilize multiple frequency bands to adapt to dynamic environmental settings. Our project has three major initiatives:-Deploy a wireless research testbed to enable study across a vast array of urban environments -Design multi-band wireless hardware and reconfigurable embedded software tools that enable context-driven, cognitive switching across frequency bands to improve performance in the aforementioned environments-Develop an open-access data repository of wireless performance in multiple urban scenarios and across frequency bandsThe project incorporates topics across disciplines such as wireless theory, embedded programming, hardware design, and ubiquitous computing. Student involvement in courses and research will allow cross-disciplinary intellectual growth. Further, field measurements will be made available to the research community. Finally, handheld mobile devices are increasingly being used as the primary method for under-represented groups to access the Internet. This infrastructure and resulting research will improve the performance these devices.

众所周知，无线系统的性能高度依赖于环境的特性。 尽管无线设备感知其周围环境的能力不断增强，但无线系统尚未充分利用上下文数据来提高性能。为此，Dallas-ARea上下文感知认知研究测试平台（DART-CAR）允许在一个测试平台内研究从室内实验室到室外高速公路速度的各种移动的和静态环境中的无线性能。我们的硬件平台可在许多不同的无线频段上运行，以实现实时、多频段操作。这种首创的基础设施对于设计利用多个频带来适应动态环境设置的上下文感知和认知算法至关重要。我们的项目有三个主要举措：-部署一个无线研究测试平台，使研究跨越大量的城市环境-设计多频段无线硬件和可重构的嵌入式软件工具，使上下文驱动，认知切换跨频段，以提高在上述环境中的性能-开发一个开放访问的数据存储库的无线性能在多个城市场景和跨频段该项目包括跨学科的主题，如无线理论，嵌入式编程，硬件设计，和无处不在的计算。 学生参与课程和研究将允许跨学科的智力增长。 此外，还将向研究界提供实地测量结果。 最后，手持移动的设备越来越多地被用作代表性不足的群体上网的主要方法。 这种基础设施和由此产生的研究将提高这些设备的性能。
