Rohde & Schwarz Supports the Development and Certification of HSDPA Mobile Phones

Europe : Rohde & Schwarz currently provides the majority of the validated 3G protocol test cases for HSDPA (high-speed downlink packet access) in accordance with the 3GPP TS 34.123 specification. Rohde & Schwarz is the only manufacturer to cover the FDD V (frequency division duplex) frequency band, offering six validated test cases. Rohde & Schwarz also has more than nine validated test cases for the FDD II frequency band.

Mobile radio manufacturers are currently dedicating intensive effort to
developing HSDPA-compatible terminals such as PCMCIA data cards and mobile phones. With Work Item 14, the European Global Certification Forum (GCF) has defined a packet of 55 signaling test cases for certification. At the end of July, the North American PTCRB (PCS Type Certification Review Board) officially recognized the validation results of Rohde & Schwarz for the FDD II and FDD V frequency bands approved in the USA. By providing a total of 15 protocol test cases validated for HSDPA, Rohde & Schwarz is making a large contribution to the further development of the UMTS standard. Thus, a major requirement for the on schedule market launch of the terminals has been met.

The new protocol test cases run on the Protocol Tester R&S CRTU-W which is already a success on the market. The protocol tester, which covers all frequency bands defined in the 3GPP standards, merely requires the addition of the R&S CRTU WA02 and R&S CRTU-WC51 software options.

These products are now available from Rohde & Schwarz.
