This project, evaluating protocols for wireless networks and developing scaling techniques for physical environments, aims at deploying an anechoic chamber for interference control, forming a testbed, referred to as the Wireless Wind Tunnel. The uses of the testbed focus on: Evaluation of wireless protocols (WP) in controlled environments, Development of channel models suitable for simulation-based evaluation of WPs, and Evaluation of techniques for scaling the physical environment to facilitate realistic wireless experiments.The Wireless Wind Tunnel (WWT) addresses some of the limitations based on computer evaluations resulting from the present insufficient understanding of channel and system models for wireless networks. These are not well understood and brute force accurate simulation of the wireless environment are at present too complex. Existing hardware testbeds suffer from one or both of the following shortcomings: Experiments often cannot be repeated due to interference by other wireless devices operating in the same frequency range and The parameters of the experiment (such as the mobility patterns of the mobiles and scatterers in the environment) are not fully controllable.Broader Impact: This work impacts the education mission, including course work, laboratories, student projects. The testbed will serve as a demonstration tool. New educational opportunities will open involving experimental research providing better training and motivation. Facilities will be made available to a larger pool of researchers. Additional impact is expected on communications systems in practice.

该项目评估无线网络协议并开发物理环境的缩放技术，旨在部署一个用于干扰控制的消声室，形成一个被称为无线风洞的测试平台。试验台的用途集中在：在受控环境中评估无线协议（WP），开发适合WP仿真评估的信道模型，和评估缩放物理环境的技术，以促进现实的无线电实验。无线风洞（WWT）解决了目前对信道和系统模型的理解不足而导致的基于计算机评估的一些限制，无线网络。这些都没有很好地理解和蛮力准确的模拟无线环境目前太复杂。现有的硬件测试平台具有以下缺点中的一个或两个：由于在相同频率范围内操作的其他无线设备的干扰，实验经常不能重复，并且实验的参数（例如环境中移动体和散射体的移动模式）是不完全可控的。这项工作影响教育使命，包括课程工作，实验室，学生项目。该试验台将作为一个示范工具。新的教育机会将开放，包括实验研究，提供更好的培训和激励。将向更多的研究人员提供设施。预计在实践中会对通信系统产生更多影响。
