| A self-contained system for obtaining the floor number of a 9-1-1 call from a mobile telephone in a multi-story building |
| When a person dials 9-1-1 from a multi-story building using a mobile phone, their floor and room number are not available if they are unable to give the information orally to the Operator. This has been an outstanding problem for many years, since more than 80% of 9-1-1 calls are placed using mobile phones. GPS and triangulation of cell towers are usually able to provide the street address of the building, and this information can be passed to the First Responder. However, the floor number is not obtainable with these methods. We have developed a system for finding the floor number of a 9-1-1 caller in a multi-story building, using the difference in barometric pressure between the caller's mobile phone and the mobile phone or tablet of the First Responder as they enter the building in question. Accuracies of ±1 floor are easily obtainable using an average floor-to-floor distance in the building. A video of an iPhone application using this method will be shown. |
