A Crowd Monitoring Methodology based on the Analysis of the Electromagnetic Spectrum

In this work, a system able to monitor the crowd density detecting mobile phone communications through analysis of electromagnetic spectrum is proposed and experimentally assessed. The variations are collected with low-cost analyzer, high gain log-periodic directive antenna (LPDA). objective relate spectral power in given frequency band estimate connections present number people area. particular, linear regression estimator, whose parameters have been calculated least square method modeled considering experimental data controlled environment, permits us infer customers detected on band. obtained results demonstrated efficacy method, which can be used not only monitoring scenario, but it also for commercial activities detect presence pervasiveness different companies.
