E6965A Location Server Emulator for SUPL A-GPS Device Testing

Secure User Plane for Location (SUPL) is a technology which that uses existing infrastructure and standards to transfer location services (LCS) data over a user plane bearer, such as Internet Protocol (IP). A centralized SUPL Location Platform (SLP) connects to the system, enabling cellular networks and mobile devices to offer Assisted GPS (A-GPS) capability. Detailed specifications exist today which enable the use of SUPL in GSM, UMTS, CDMA, LTE, UMB, and WiMAX™ networks.

The Keysight E6965A location server emulator is the first commercial bench-top solution supporting SUPL functional test using over-the-air connection to a SUPL-enabled terminal (SET). It provides the elements of the SLP that are needed to test such devices, and may be combined with other Keysight test equipment to form a system that provides satellite simulation, cellular base-station emulation, and the messaging required for SUPL testing.

The location server emulator is designed for use with the Keysight 8960 (E5515C/E5515E) series 10 wireless communications test set

If required, the Keysight ESG-C with E4438C-409 global positioning system personality can be used to provide GPS signal simulation
