Rohde & Schwarz and KTF present interoperability tests for 3G mobile phones
Smooth interaction of user equipment and infrastructure is crucial to the success of innovative services offered by mobile radio operators. This is why operator-specific signaling tests are an important component in the quality assurance of services in WCDMA networks. With its R&S®CRTU-W protocol tester, which features a C++ programming interface and more than 1000 different interoperability test (IOT) cases, Rohde & Schwarz offers an ideal platform to respond to the specific needs of network operators.
To handle the IOTs efficiently and at a favorable cost, the South Korean network operator Korea Telecom Freetel (KTF) and Rohde & Schwarz have jointly specified test scenarios for the R&S®CRTU protocol test platform. These scenarios were implemented on the R&S®CRTU-W by Rohde & Schwarz Systems & Communications Asia in Singapore and will be available to manufacturers of user equipment as of August. Once the first project phase was concluded, 170 test scenarios, including tests for KTF-specific services such as Free Zone, were presented in Seoul at the end of May. By performing tests that verify compliance with KTF quality criteria when the equipment is still in the lab, manufacturers of user equipment will considerably speed up the approval procedure.
Rohde & Schwarz has extensive experience in implementing interoperability tests. Prior to the project for Korea Telecom Freetel, IOT packages for other network operators such as NTT DoCoMo and AT&T had already been implemented. In addition, R&S®CRTU protocol testers are established test platforms for GCF and PTCRB licensing tests and support both WCDMA and GSM.
