Rohde & Schwarz collaborates with Qualcomm and Iridium Communications to test Snapdragon Satellite

01 March 2023

Rohde & Schwarz has announced that its tried-and-tested R&S CMW100 communications manufacturing test set for non-signaling wireless device testing has been validated by Qualcomm Technologies for Qualcomm Development Acceleration Resource Toolkit (QDART) to verify Iridium waveforms used for the new Snapdragon Satellite solution. Rohde & Schwarz is the first to supply test and measurement equipment to support non-signaling research and development and production testing of this new feature. This will help enable the Android ecosystem to reliably offer the satellite-based global emergency and two-way messaging provided by Iridium Communications on next-generation smartphones.

Powered by the Snapdragon 8 Gen 2 Mobile Platform and supported by Iridium, the satellite provider, Snapdragon Satellite will enable smartphones to offer global connectivity and support two-way emergency messaging, SMS texting, and other messaging applications in remote, rural and offshore locations. The smartphone solution utilizes Iridium's weather-resilient L-band spectrum for uplink and downlink.

The R&S CMW100 communications manufacturing test set is part of the Rohde & Schwarz single-box tester portfolio, which provides universal and efficient test instruments for all modern cellular and non-cellular standards. The flexible R&S CMW100 radio frequency (RF) interface permits simultaneous testing of up to eight devices. It has a continuous frequency range up to 6 GHz and RF bandwidth up to 160 MHz. A wide range of methods that reduce test times and maximize capacity utilization are implemented in the test platform for high measurement performance and accuracy.

For advanced wireless technologies, Rohde & Schwarz offers the R&S CMP180 with an enhanced frequency up to 8 GHz and bandwidth up to 500 MHz. Double the number of vector signal analyzers (2xVSA), vector signal generators (2xVSG) and RF ports (2x8) enable even more simultaneous measurements of technologies and devices in a VSA/VSG single-box tester. Both instruments are validated by Qualcomm Technologies for QDART, making them a future-proof investment for original equipment manufacturers.

At Mobile World Congress 2023, Rohde & Schwarz is showcasing in hall 5, booth 5A80 of Fira Gran Via in Barcelona, a setup featuring a radio communications tester performing Iridium waveform verification in line with QDART for a Snapdragon 8 Gen 2 Mobile Platform.
