Abstract

This paper presents a study of the performance of A-GPS based on OMA SUPL (Secure User Plane Location) in urban areas. Field tests are conducted to compare A-GPS versus conventional GPS using commercial cell phones. Test scenarios include urban indoor and urban outdoor areas. Performance is measured in terms of TTFF (Time To First Fix) location delay and location accuracy. Results for a dedicated handheld GPS receiver are also provided as a reference.
