R&S CMX500 OBT wideband radio communication tester and the R&S SMBV100B vector signal generator from Rohde & Schwarz.

ETS-Lindgren integrates R&S CMX500 and R&S SMBV100B for 5G A-GNSS antenna performance testing

  • ETS-Lindgren and Rohde & Schwarz continue their long-term collaboration and have enabled antenna performance measurements with comprehensive assisted global navigation satellite system (A-GNSS) capabilities for 5G NR.
  • The R&S CMX500 OBT wideband radio communication tester and the R&S SMBV100B GNSS simulator in conjuction with EMQuest software from ETS-Lindgren support current and evolving 5G NR location based service standards.
  • Both Rohde & Schwarz instruments can be seamlessly integrated into new and existing CTIA-compliant over the air (OTA) antenna measurement solutions from ETS-Lindgren.

ETS-Lindgren teamed up with Rohde & Schwarz for a turnkey 5G NR A-GNSS antenna performance testing solution that uses the R&S CMX500 OBT wideband radio communication tester and the R&S SMBV100B vector signal generator with GNSS simulator in their 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 comunications (5G NR) makes use of existing and new location based services, such as assisted GNSS (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 one-box tester (OBT) from Rohde & Schwarz is an single-box 5G, LTE and Wi-Fi network emulator. It features a location based services server that seamlessly works with the R&S SMBV100B GNSS simulator. Both instruments combine to form a 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 RF 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 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.
