The MGP6200 solution supports AGPS-based location applications on GSM, GPRS and 3G UMTS, and supports roaming across diverse service areas, seamlessly switching between modes to utilize available aiding information. It does not require costly network equipment, such as location measurement units (LMUs), to operate effectively. Compelling advantages over other location technologies include low-cost implementation, crisp AGPS operation in asynchronous networks and three different modes of operation to address different application requirements. Ranging from full-featured mobile-assisted to unassisted standalone operation, the MGP6200 can optimise the location solution for periodic or continuous position reports, or even for applications where no assistance data is available from the wireless network. Through QUALCOMM's Wireless Internet Launchpad suite, the position location component provides mobile e-commerce and wireless Internet applications with easy access to location information and control over their operation. Leading-edge algorithms and a high level of integration provide unmatched GPS acquisition speed, accuracy and sensitivity. At the same time, handset costs, space requirements and battery usage are minimized. This chip appears to be the center of focus from the White Papers on UMTS Networks: Synchronous vs. Asynchronous which discusses self synchronous and quasi synchronous alternatives to gps. In effect, these alternative methods can be used to synchronize the UMTS base stations without altering 3GPP standards.
