论文摘要
COVID-19波之后的时期称为回声周期。在室外环境中估计人群尺寸在回声周期中至关重要。为了使小时的需要，制作一个简单而灵活的工作系统。本文提出并评估了在室外环境中进行人群估计的非侵入性，被动和成本效益的解决方案。我们将提出的系统称为基于LTE通信基础架构的环境传感或LTE-Commsense。该系统不需要任何主动信号传输，因为它使用LTE发射信号。因此，这是一种强大的，简单的低占地面设备。重要的是，无法使用这种方法获得人群中人民的个人身份。首先，系统使用实用数据来确定室外环境是否为空。如果没有，它试图估计占据近距离地区的人数。使用实际数据的绩效评估证实了这种提出的方法的可行性。
The period after the COVID-19 wave is called the Echo-period. Estimation of crowd size in an outdoor environment is essential in the Echo-period. Making a simple and flexible working system for the same is the need of the hour. This article proposes and evaluates a non-intrusive, passive, and costeffective solution for crowd size estimation in an outdoor environment. We call the proposed system as LTE communication infrastructure based environment sensing or LTE-CommSense. This system does not need any active signal transmission as it uses LTE transmitted signal. So, this is a power-efficient, simple low footprint device. Importantly, the personal identity of the people in the crowd can not be obtained using this method. First, the system uses practical data to determine whether the outdoor environment is empty or not. If not, it tries to estimate the number of people occupying the near range locality. Performance evaluation with practical data confirms the feasibility of this proposed approach.
