The proposed work describes a novel way to use the existing communication infrastructure based sensing to monitor the change in the environment (CommSense). The key idea to this technology lies in focusing on already known information from received signal e.g. Pilot carriers in the communication signal frames. Comparing the received signal with the expected properties of the pilot, we can get an estimate of change in the environment based on change in channel properties. Existing Long Term Evolution telecommunication infrastructure is utilized for this environment sensing task. After the channel characteristics are estimated, those can be used to obtain phenomenological knowledge of the environment using Application Specific INstrumentation framework. This system was implemented using software defined radio platform and GNURadio software support.

CommSense：基于通信基础设施的环境监测传感仪器

拟议的工作描述了一种使用现有基于通信基础设施的传感来监视环境变化（CommSense）的新颖方法。该技术的关键思想在于集中于来自接收信号的已知信息，例如通信信号帧中的导频载波。将接收到的信号与导频的预期特性进行比较，我们可以基于信道特性的变化来估计环境的变化。现有的长期演进电信基础设施被用于该环境感测任务。估计通道特征后，可以使用“专用仪器”框架将其用于获取环境的现象学知识。该系统是使用软件定义的无线电平台和GNURadio软件支持实现的。
