Permanent Link to Rohde & Schwarz and Bluetest partner on A-GNSS OTA antenna testing
Testing the antenna performance of GNSS signals such as GPS, GLONASS, Beidou, Galileo and Metropolitan Beacon Systems (MBS) is key to location accuracy performance of a mobile device.
To address the testing need for A-GNSS services, Rohde & Schwarz and Bluetest are partnering in creating test concepts for over-the-air (OTA) antenna measurements.

The two companies integrate the R&S LBS Server, a software component running on the R&S CMW500 wideband radio communication tester, and the Bluetest OTA test solution for A-GNSS systems based on Bluetest’s RTS65 reverberation chamber and Bluetest’s Flow measurement software.
In the test setup, the R&S LBS Server controls the Rohde & Schwarz base-station simulator R&S CMW500 for LTE, WCDMA and GSM, and uses the R&S SMBV100B vector signal generator for simulation of GNSS and MBS signals.
A simple and straightforward upgrade of the setup for 5G will be available soon, making sure that investments are protected and most relevant standards can be tested with the same system.
The R&S LBS Server is an essential part of the R&S TS8991 OTA Performance Test System. This cooperation between Rohde & Schwarz and Bluetest marks the first time that the R&S LBS Server, used here as a software tool on R&S CMW500, is available also for third parties.
“We are delighted to collaborate with Bluetest to contribute with our test and measurement expertise to OTA 4G/3G/GSM and GNSS technology development,” said Alexander Pabst, vice president, Systems and Projects at Rohde & Schwarz. “With a strong global footprint for location based services LBS and close cooperation with partners, Rohde & Schwarz is committed to accompanying the evolution path from OTA testing for GPS, GLONASS, BeiDou and Galileo with innovative test and measurement solutions.”
“The addition of A-GNSS measurements means that the full range of wireless technology in a modern cellular device can be verified with just one test solution,” said Robert Rehammar, Bluetest CTO. “Bluetest has enjoyed the close cooperation with Rohde & Schwarz on this project, leading to a very strong joint solution and customer offering.”
