ETS-Lindgren, a global leader in antenna measurement solutions, has collaborated with Rohde & Schwarz, a renowned provider of test and measurement equipment, to enhance antenna performance testing for 5G A-GNSS (Assisted Global Navigation Satellite System). This partnership combines the capabilities of the R&S CMX500 OBT wideband radio communication tester and the R&S SMBV100B GNSS simulator with ETS-Lindgren’s EMQuest software, offering comprehensive 5G NR A-GNSS testing capabilities.
5G NR (New Radio) utilizes location-based services, including A-GNSS, to provide faster and more accurate positioning information for various applications. This technology is crucial for cellular devices, and GNSS (Global Navigation Satellite System) plays a pivotal role in ensuring reliable signal reception and positioning accuracy.
The R&S CMX500 OBT is a versatile one-box tester that supports 5G, LTE, and Wi-Fi network emulation and features a location-based services server compatible with the R&S SMBV100B GNSS simulator. Together, these instruments create a powerful solution for A-GNSS testing of LTE and 5G NR, meeting OTA (Over The Air) antenna performance test requirements. This solution is especially valuable for applications in smartphones, automotive systems, and high-precision devices.
The R&S SMBV100B simulator provides the ability to simulate all GNSS satellite constellations at any location and time, ensuring comprehensive testing of GNSS OTA performance. Meanwhile, the R&S CMX500 supports LTE and 5G NR cellular network simulations, including A-GNSS assistance data messaging and secure user planes.
The integration of the R&S CMX500 OBT and the R&S SMBV100B enables users to conduct essential GNSS OTA tests necessary for certification and assessing positioning performance. ETS-Lindgren’s EMQuest Antenna Measurement software facilitates the seamless integration of these instruments into a turnkey 5G NR A-GNSS antenna performance solution.
The R&S CMX500 is not only suitable for A-GNSS testing but also supports data performance and voice quality measurements, making it a versatile tool for various phases of product development, service/repair, regulatory testing, conformance, and network operator carrier acceptance.
This collaboration between ETS-Lindgren and Rohde & Schwarz strengthens the capabilities of antenna performance testing, enabling the deployment of new location-finding technologies and improving GNSS receiver performance in 5G NR networks. It further solidifies ETS-Lindgren’s position as a leading provider of OTA test systems worldwide.
Bryan Helmick, Product Manager for Wireless Device Test at Rohde & Schwarz, emphasized the importance of GNSS capabilities in 5G NR networks and praised ETS-Lindgren’s expertise in antenna measurement solutions. James Young, Sr. Director of Business Development at ETS-Lindgren, highlighted the flexibility and versatility of the EMQuest software, which enables the integration of new technologies and instrumentation seamlessly. This collaboration is a significant step forward in advancing the capabilities of antenna performance testing, particularly in the context of evolving 5G NR networks and location-based services.
