"At the 2008 Workshop on Precision Indoor Personnel Location and Tracking for Emergency Responders, to be held at Worcester Polytechnic Institute Aug. 4-6, four solutions to the enormous technical challenge of precisely locating first responders inside buildings will be demonstrated in carefully controlled trials. Now in its third years, the workshop, the only national forum on the precision indoor location, will bring together about 120 leading researchers, government representatives, and first responder community members."
