Crowd Size Estimation with Passive Electromagnetic Sensing

2023 IEEE International Conference on Communications Workshops (ICC Workshops), 2023
Abstract: Crowd size estimation has become of even greater significance than before COVID-19 restrictions. At the same time, wireless technologies are ubiquitous and change rapidly; we hypothesise that we can estimate crowd sizes from electromagnetic (EM) activity, agnostic from the used communication technology.
