MIT researchers create map of WiFi users

MIT's WiFi service stretches across its 9.4 million sq.ft. campus, and now the school has implemented a mapping system that lets students see whether a study hall or cafeteria is crowded with WiFi users. The system allows students to log into the network, check out the maps, and then decide the best place to work based on how crowded an area is. Some just log in to see where their friends are (most remain anonymous, but the system can "tag" you, too). The school also projects the maps onto large Plexiglas rectangles at the school's museum.
