US E911 Location: Two Imperfect Technologies are Better  than One
US operators have a tremendous responsibility, imposed by the Federal Communications Commission, to provide essential location information to public safety answering points across the nation. Autonomy in how operators meet the FCC requirements led the four major US operators to adopt two main types of location systems to satisfy E911 requirements. However, both technologies have limitations in some environments – imperfect solutions for an acutely important system that could be life or death to the emergency wireless caller.
