A Spatial Data Focusing and Generalized Time-invariant Frequency Diverse Array Approach for High Precision Range-angle-based Geocasting

no code implementations24 Feb 2023 Guylian Molineaux, Francois Horlin, Philippe De Doncker, Julien Sarrazin

A novel unified frequency diverse array (FDA) and spatial data focusing (SDF) approach is proposed to simultaneously overcome time-variance and precision constraints of conventional FDA in geocasting, i. e., spatially confined broadcasting, scenarios.

Joint data rate and EMF exposure analysis in Manhattan environments: stochastic geometry and ray tracing approaches

no code implementations26 Jan 2023 Charles Wiame, Simon Demey, Luc Vandendorpe, Philippe De Doncker, Claude Oestges

Using this framework, a number of performance metrics are derived: first moments, marginal distributions and joint distributions of the data rate and exposure.

Monitoring Large Crowds With WiFi: A Privacy-Preserving Approach

no code implementations20 Oct 2020 Jean-François Determe, Sophia Azzagnuni, Utkarsh Singh, François Horlin, Philippe De Doncker

From this model, we derive a concentration inequality that highlights the accuracy of our crowd count estimator.

MAC Address Anonymization for Crowd Counting

no code implementations21 Sep 2020 Jean-François Determe, Sophia Azzagnuni, Utkarsh Singh, François Horlin, Philippe De Doncker

Research has shown that counting WiFi packets called probe requests (PRs) implicitly provides a proxy for the number of people in an area.
