Abstract
Many approaches have been advanced for locating the geographic position of wireless phones, both for emergency response purposes and for emerging location-based services. Depending mainly upon the services envisioned and the particulars of the air interface, one or another approach appears appealing. Increasingly, the assisted-GPS approach is gaining recognition as the approach that can best meet all requirements. Among the important requirements are those mandated in the USA by the Federal Communications Commission (FCC) for Enhanced 911. Assisted GPS provides the best accuracy for use in location services. It is rooted in the suitability of wireless networks to provide data over the air to enable fast acquisition and lower power consumption, as well as provide indoor operation-capabilities that conventional GPS cannot provide. The assisted-GPS approach promises to enable a new industry of location-based services and important new safety measures.
