NeTS-WN: Gigabits/Sec/User

该研究项目探讨了在室内环境中为用户提供高数据速率无线连接的问题。目标是即使在存在多个用户的情况下也能够达到Gbps/用户速率。我们正在研究的技术是使用60 GHz ISM频谱，其特殊的传播特性使其非常适合这项任务。所采取的方法是在房间中使用多个空间分布的智能天线，以在需要时和需要时提供覆盖。所有的天线都连接到一个接入点，这使我们能够动态地改变频谱和用户之间的链路分配（随着他们的移动或需求的变化）。实际上，接入点的设计也是新颖的，因为它需要支持几个Gbps的总吞吐量。这项工作的创新包括利用60 GHz的特殊属性，设计有效频谱重用的算法，支持房间内的多个MAC协议以更好地适应用户需求，新颖的接入点架构，以及系统设计与用户访问模式之间的紧密相关性。所遵循的方法主要是理论和仿真为基础的。提供高数据速率的无线接入到用户是一个重要的问题，推动越来越多的服务通过无线管道。这个项目与以前的项目不同，因为这个项目有一个雄心勃勃的目标，即提供Gbps/用户。研究是物理层、MAC层和算法设计的混合。预期的结果将在频谱分配以及新的接入点设计领域做出重大贡献。该项目的一个产品是一个详细的60 GHz室内通信的Opnet/Matlab仿真环境。这对更大的无线研究社区很有用，也将被纳入实验室实习课程。在推广方面，PI与PSU的星期六学院（SA）合作，为K-12学生提供服务。PI对SA的贡献是讲授高速无线网络的基本概念（以及这个令人兴奋的领域的未来）。PI在SA的帮助下，将积极招募高中学生，特别是少数民族和代表性不足的学生，在科学工程学徒计划下实习，实习生在为该项目做出贡献的同时进行探索和体验。

This research project examines the problem of providing high data-rate wireless connectivity to users in indoor environments. The goal is to be able to reach gbps/user rates even when there are multiple users present. The technology that we are researching is to use is the 60 GHz ISM spectrum whose special propagation properties make it ideally suited to this task. The approach taken is to use multiple, spatially-distributed smart antennas in a room to provide coverage where needed and when needed. All the antennas are connected to a single access point which allows us to dynamically change spectrum and link allocation among the users (as they move or as their needs change). Indeed, the design of the access point is also novel since it needs to support a gross throughput of several gbps.The innovations in this work include the exploitation of the special properties of 60 GHz, design of algorithms for efficient spectrum reuse, support for multiple MAC protocols within a room to better adapt to user needs, a novel access point architecture, and a tight correlation between design of the system and user access patterns. The methodology being followed is primarily theoretical and simulation-based.Providing high data-rate wireless access to users is an important problem given the drive to push more and more services through the wireless pipeline. This project differs from previous ones in that this project has the ambitious goal of delivering gbps/user. The research is a mix of physical layer, MAC layer, and algorithmic design. The expected results will make significant contributions in the areas of spectrum allocation as well as novel access point designs. The work will also potentially impact future development standards for these environments.One product of this project is a detailed Opnet/Matlab simulation environment for 60GHz indoor communications. This is useful to the larger wireless research community and will also be incorporated into the curriculum for lab practicum. In terms of outreach, the PI collaborates with the Saturday Academy (SA) of PSU, which serves K-12 students. The PI's contribution to SA is to lecture on rudimentary concepts of high-speed wireless networking (and the future of this exciting area). The PI, with the help of SAs, will actively recruit high-school students, particularly minority and under-represented, to intern under the Apprenticeships in Science & Engineering program, in which interns explore and experience while contributing to this project.
