The R&S TS8991 over-the-air (OTA) test system from Rohde & Schwarz is the first to be approved by CTIA Certification for testing 5G assisted-global navigation satellite system (A-GNSS) antenna performance. This solution measures the performance of the GNSS receiver in a wireless device. This is critical because A-GNSS is used for E911 emergency calls over 5G.

The latest Test Plan for Wireless Device OTA Performance Version 4.0.x from CTIA Certification added 5G FR1 EN-DC to the existing A-GPS L1 OTA specification. The previously published Version 6.0.x added 5G FR1 SA, A-GPS L5 and A-Galileo E1, which are soon to start the CTIA Certification validation process.
The R&S TS8991 test system from Rohde & Schwarz is a turnkey solution for meeting CTIA Certification OTA test requirements for 2G/3G A-GPS, 4G LTE A-GNSS and now also 5G A-GNSS. This system consists of the R&S CMX500 5G one-box signaling tester, the R&S SMBV100B satellite simulator and an anechoic wireless performance test chamber (WPTC). It features a high degree of system integration and is easily upgradeable. Every component is controlled using the R&S CONTEST software, allowing for fully automated OTA measurements in compliance with CTIA Certification Test Plans.
The R&S CMX500 is a one-box solution for all mobile device testing applications. It supports transmitter and receiver radio frequency parametric measurements as well as testing for data throughput, audio quality and battery life. This solution is integrated into the R&S TS8991 antenna performance test system to provide signaling capabilities to a device under test (DUT) as well as measure the receive sensitivity and transmit power. The R&S CMX500 covers the most advanced requirements for wireless communications testing and supports the latest 3GPP and IEEE technologies.
The R&S SMBV100B is a satellite simulator that supports all major satellite navigation technologies and satellite constellations. With the CMX500 location-based services, it supports all 3GPP-based A-GNSS technologies.
The R&S WPTC OTA Test Chamber is a high-performance OTA anechoic test chamber available in a range of chamber sizes for different testing needs.
