A WiFi Sniffing Solution for Safe Return to Classes

摘要

The current pandemic caused by the SARS-CoV-2 virus has affected all sectors of activity through quarantine measures imposed to stop the spread of the disease. In the absence of safe treatment, social distancing and wearing a face mask are the only weapons to combat this pandemic. Unfortunately, social distance has led to the migration of education to a distance format reducing the interaction between teachers and students. Even if, through the vaccination process, the spread of COVID19 disease will be slowed down, the physical return to schools and universities will be done under the sign of social distancing and health precautions. This article proposes a simple and low-cost solution for monitoring the density of people in a room by monitoring WiFi traffic. Because the solution can be implemented on a large scale, it is suitable for implementation as a centralized monitoring and warning solution at school or university campus level.
