In the last 10 years, the possibility of using wireless connections to deduce mobile devices' locations has been a hot research topic in industry and academia. GPS systems frequently fail in large buildings, and even when they don`t, they`re not very precise. Firefighters tracking each other in a smoke-filled building, soldiers trying to determine each other`s position in urban environments, medical staff trying to locate equipment or each other in a busy hospital, and warehouse workers trying to find merchandise in an aisle of pallets stacked 20 feet high all need higher-resolution location information than GPS can provide.
