A Nov. 14 article in the Toronto-based Globe and Mail discusses the attributes of a newer, smarter campus-wide wireless network at the Massachusetts Institute of Technology. Using Bluetooth wireless technology, campus engineers reportedly have equipped the network with a unique tracking device that maps exactly how many students, faculty, and other users are logged on to the network from any location at any time. “With these maps, you can see down to the room on campus how many people are logged on,” said Carlo Ratti, director of the school’s SENSEable City Laboratory, which created the maps. “You can even watch someone go from room to room if they have a handheld device that’s connected.”
