Test cases go beyond basic telephony

Validated test cases for push-to-talk over cellular and multimedia message service are available for the CRTU protocol tester and the CMU200 universal radio communication tester.

Push-to-talk over cellular (PoC), multimedia message service (MMS) and videotelephony are features that make mobile handsets much more than just telephones.

For this purpose, standardisation bodies such as the Global Certification Forum (GCF) specify special test cases so that manufacturers can develop and certify user equipment that includes the aforementioned functionalities.

As Rohde and Schwarz is able to provide both the test cases and the necessary hardware, it is a worldwide leader in GCF-relevant application tests.

For the R and S CRTU protocol tester family and the R and S CMU200 universal radio communication tester, the company now offers validated test cases for MMS and PoC.

The extensive test packages for both applications are based on the R and S CRTU-ATE application test environment software platform and include in addition to the test cases also an MMS or PoC test server.

Rohde and Schwarz also again leads the way when it comes to validated test cases for videotelephony.

The R and S CRTU-W protocol tester can be upgraded with an option for this function.

The specialist for T and M equipment was among the first companies worldwide to offer validated test cases for certifying the required user equipment.

In addition to RF, audio and application tests, manufacturers of mobile phones can perform tests at all protocol layers - from layer 1 down to the application level - by using the R and S CRTU and R and S CMU200 mobile phone testers from Rohde and Schwarz.
