If WiFi can track a heartbeat through walls, why can’t I get internet in my corner bathroom? Jason Cole was trying to figure that out too, but unlike me, he’s a PhD student in physics. So he mapped his own apartment and assigned refraction values to the walls (shown above), then applied so-called Hemholtz equations to model the electromagnetic waves. As detailed in his (math-drenched) blog, the best spot for his router was where you’d expect: directly in the center. Since that was out of the question, he was still able to get “tendrils” of internet by placing it in the corner of the apartment. His experiment implies that even in a distant room you could eke some connectivity by judiciously shifting around your laptop. Some of his readers want him to turn into a WiFi mapping web service — unfortunately, he thinks the idea is “unfeasible” due to the processing time and assumptions made.
