Disaster Tip - Use Your Phone's HotSpot

Your smartphone's WiFi hotspot might double as a disaster rescue beacon. Okay, pretend you are in the middle of a disaster. You can't contact your team, or your fellow rescue workers, or your family. All the cell phone networks are down. Your smart phone is now useless, right? Not. These guys have invented an app that does something very simple; it substitutes your phone's hotspot app with an SOS rescue message. Someone using the same app can then find you within a few hundred feet by scanning for hotspots. Very cool. Very nice. Very helpful.
