Spirent Communications plc has announced that the Spirent UMTS Location Test System (ULTS) now supports full certification testing of 3G Partnership Project’s (3GPP) Assisted GPS (A-GPS) RF Minimum Performance test cases for both W-CDMA and GSM devices. With this latest capability, Spirent test equipment can support all A-GPS testing standards including RF performance, signaling conformance, and Secure User Plane (SUPL) Application Enabler, according to the company.

Spirent ULTS now enables mobile operators and manufacturers offering W-CDMA devices to certify 3GPP TS 34.171 A-GPS RF Minimum Performance test cases. The validation and certification of these test cases are based on the requirements of the Global Certification Forum (GCF) and the PCS Type Certification Review Board (PTCRB). In addition, for the first time, customers can validate GSM devices for multiple 3GPP TS 51.010 A-GPS RF Minimum Performance test cases based on PTCRB specifications.
Spirent ULTS had already validated five of the six TS 34.171 test cases and now supports certification testing of the sixth test case — Fine Time Assistance (FTA). FTA is a technique that enables improved receiver sensitivity and faster time-to-first-fix (TTFF) by providing highly accurate timing information to the handset. Spirent’s validation of TS 51.010 test cases allows the evaluation of the A-GPS performance of GSM devices on the following factors: position accuracy, TTFF, multipath and dynamic range performance.
