Abstract :
New services in wireless communications are enforcing needs for accurate indoor and outdoor location technologies. Existing technologies are offering different coverage and accuracy, but none a pervasive location service. This paper first assesses the coverage and accuracy of the fundamental positioning technologies - GPS, WLAN-based, and GSM-based (Cell-ID and Trilateration) - by systematic measurements in various environments both indoor and outdoor. Then, an Always Best Located (ABL) algorithm is introduced and experimental performance results obtained in real situations are presented.
