ETS-Lindgren teamed up with Rohde & Schwarz for a turnkey 5G new radio (NR) assisted global navigation satellite system (A-GNSS) antenna performance testing solution that uses the R&S CMX500 one-box tester (OBT) wideband radio communication tester and the R&S SMBV100B vector signal generator with GNSS simulator in their market leading over-the-air (OTA) antenna performance measurement solution. When Rohde & Schwarz test equipment is paired with CTIA-compliant EMQuest antenna measurement software and chamber systems from ETS-Lindgren, they provide comprehensive 5G NR A-GNSS test capabilities.
The fifth generation of cellular communications — 5G NR — makes use of existing and new location-based services, such as A-GNSS, where radio technology provides information about available satellites for faster positioning. Satellite based positioning remains critical for cellular devices and GNSS has been improved with additional constellations for better signal reliability accuracy and integrity.
The R&S CMX500 OBT from Rohde & Schwarz is one of the most capable single-box 5G, LTE and Wi-Fi network emulator on the market and features a location-based services server that seamlessly works with the R&S SMBV100B GNSS simulator. Both instruments combine to form the most powerful solution for A-GNSS testing of LTE and 5G NR that meets OTA antenna performance test requirements and is ideal for the EMQuest Antenna Measurement software from ETS-Lindgren.
While the R&S SMBV100B simulates all possible GNSS satellite constellations at any time and geolocation, the R&S CMX500 supports LTE and 5G NR cellular network simulations. The R&S CMX500 also supports A-GNSS assistance data messaging over control planes (LPP over RRC) and secure user planes (SUPL). Integrating the R&S CMX500 OBT and the R&S SMBV100B enables users to conduct crucial GNSS OTA tests essential for certification and assessing positioning performance in smartphone, automotive and high-precision applications. ETS-Lindgren has a worldwide installed base of OTA systems driven by its EMQuest Antenna Measurement software that combines these capabilities into a turnkey 5G NR A-GNSS antenna performance solution.
The R&S CMX500 wideband radio communication tester is a universal test platform for commercial wireless device signaling and radio frequency parametric testing. Along with testing for location-based services and protocol stack features for A-GNSS operations, the R&S CMX500 also enables comprehensive data performance and Perceptual Objective Listening Quality Analysis (PoLQA) voice quality measurements. The internal fading simulator also makes for easy testing under realistic propagation conditions. The R&S CMX500 can be used in all phases for product development, service/repair, regulatory testing, conformance and network operator carrier acceptance.
