The TS8980LBS LTE RF test system from Rohde & Schwarz allows manufacturers of mobile wireless devices and components to perform preconfigured conformance tests to ensure that location-based services, such as LPP (LTE positioning protocol), work properly during network operation. This scalable platform supports conformance testing of international location-based services, and performs protocol tests and specific network-operator test cases that combine, for example, data-transmission tests and position location.
Based on the CMW500 wideband radio communication tester, the TS8980 can be configured to meet many different requirements, ranging from small development lab versions to complex conformance test systems. Existing customers already using the TS8980 can add the SMBV100A signal generator equipped with the LBS (location-based service) software option. The resulting configuration can perform both RF and LBS tests. With the Contest interface, designers can compile individual test plans that combine test cases from different standards in a single sequence.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
