• Prototype handsets and two types of miniature GPS antennas appropriate for small mobile devices were used on different networks.
• Trials were conducted in major cities such as Paris, Bonn, London and Utrecht.
• A single location server was hosted by France Telecom Mobile to provide location calculations support for all of the trial locations to demonstrate the cross-border capabilities and wide-area service coverage of the technology.
• CMG Telecommunications provided the interface between the location server and the network Short Message Service Center (SMSC) to test the use of SMS as "the data bearer for wireless position information."

• Callers were successfully located on successive networks during the trials in a wide range of environments.

• Open outdoor sites, including suburban neighborhoods and parkland, typical accuracies were in the 5-10 meter range.
• Outdoor testing in dense urban environments resulted in average accuracies of 30-50 meters.
• Indoor tests were conducted in a variety of structures from commercial to residential and yielded average accuracies from 30 to 45 meters, with some as precise as 20 meters.

• CMG Telecommunications assessed that SMS would be suitable for location specific applications.

"These trials not only demonstrated SnapTrack’s compatibility with SMS, but also that SnapTrack’s enhanced GPS handset-based technology represents the most cost-effective, high quality solution for seamless cross-broader, cross-network location services roaming," commented Steve Poizner, president of SnapTrack.
