Rohde & Schwarz To Minimise Field Testing For IoT Modules

  • With this solution, IoT modules can operate synchronously across all networks and conditions

  • Achieves reduced extensive real network drive tests for IoT manufacturers in different countries, resulting in faster time-to-market

IoT protocol stack features have been specified by 3GPP, but IoT devices have to interact with different network configurations worldwide. This makes it important to ensure that these features are working well in all sorts of configurations, configured by different network operators.


With this in mind, Rohde & Schwarz in association with Gemalto, a Thales company, have begun work on significantly reducing expensive and time-consuming drive tests. This collaboration enables both companies to help each other in the verification of software builds and releases.

Through this cooperation, manufacturers of IoT solutions will be able to use virtual drive tests during the development phase of CAT M1 and NB IoT modules to find and fix problems at an earlier stage. This will also enable seamless cellular coverage and reliable connectivity before the integration process continues and further field tests are performed. Network-specific integration tests and field tests include analysis of unique network configurations in different countries, challenging RF Power level conditions and verification of signalling under compelling RF environments.

Creates real network simulation

The setup consists of R&S Field-to-Lab wireless communication test system, R&S CMWcards smart network emulator and R&S CMW500/CMW290 wideband radio communication tester.

The LTE-based R&S Field-to-Lab solution supports LTE-M and NB-IoT technologies. With the same user interface, customers can seamlessly move between LTE and IoT testing. The simple process of loading the field logs, extracting the required information from the field log and generating R&S CMWcards test script helps to create a real network environment in a lab.

Unlike other simulated drive test solutions, the R&S Field-to-Lab supports 3GPP IoT features and is also the first virtual drive test solution for IoT that replicates the signalling and RF conditions in an easy-to-operate GUI on the R&S CMW500 and R&S CMW290 mobile radio testers.

Consequently, this new IoT approach enables Thales for an increasingly efficient and rapid IoT testing procedure. For Rohde & Schwarz it is an opportunity to make its IoT testing and measurement domain even stronger.
