Abstract
A method and system for determining a location of mobile and non-mobile devices in emergency situations. The method and system provide a current physical geographic location for a mobile or non-mobile device (e.g., building address, a building floor, a room on a building floor, campus, enterprise, city, state, region, country, continent, etc.) in an emergency situation. The method and system can also be used to provide a physical geographic location for a device for non-emergency situations.
