Capturing Personal and Crowd Behavior with Wi-Fi Analytics

We present a solution for analysing crowds at events such as conferences where people have networking opportunities. Often, potential social relations go unexploited because no business cards were exchanged or we forget about interest- ing people we met earlier. We created a solution built on top of ubiquitous Wi-Fi signals to accommodate for this issue, that is, a solution able to create a memory of human trajec- tories and touch points. In this paper we elaborate on the technological assets we designed to perform crowd anlayt- ics. We present small wearable Wi-Fi badges that last for the duration of an event (up to 3 days) with a single charge, as well as network equipment that senses the signals radiat- ing from these badges and contemporary mobile devices.
