长期演进技术（LTE）已经在全球范围内普及，用于商用部署4G蜂窝网络。如今，人们对移动宽带服务可以造福社会的新应用越来越感兴趣。尽管LTE的基本概念已被充分理解，但其长期演进才刚刚开始。坡道的新区域；D .研究在未授权和共享频段上的操作，在这些频段上，新版本的LTE需要与其他通信系统和雷达共存。弗吉尼亚理工大学开发了一个具有独特功能的LTE测试平台，以促进LTE研究和教育。本文介绍了弗吉尼亚理工大学的LTE测试平台，它的主要特点和组件，访问和配置机制，以及它所支持的一些研究重点。它在几个方面是独一无二的，包括广泛使用软件定义无线电技术，工业级硬件和基于软件的系统的结合，以及用户自定义实验配置和射频路径的远程访问功能。
The long-term evolution (LTE) has spread around the globe for deploying 4G cellular networks for commercial use. These days, it is gaining interest for new applications where mobile broadband services can be of benefit to society. Whereas the basic concepts of LTE are well understood, its long-term evolution has just started. New areas of Ramp;amp;D look into operation in unlicensed and shared bands, where new versions of LTE need to coexist with other communication systems and radars. Virginia Tech has developed an LTE testbed with unique features to spur LTE research and education. This pa-per introduces Virginia Tech's LTE testbed, its main features and components, access and configuration mechanisms, and some of the research thrusts that it enables. It is unique in several aspects, including the extensive use of software-defined radio technology, the combination of industry-grade hardware and software-based systems, and the remote access feature for user- defined configurations of experiments and radio frequency paths.
