HSDPA and HSUPA Solutions from Rohde & Schwarz

Europe : High speed downlink packet access (HSDPA) has long been known as a powerful enhancement to WCDMA. Its counterpart, the new high speed uplink packet access (HSUPA) standard, will be launched in 2007.

Rohde & Schwarz is supporting the introduction of HSUPA with T&M solutions for layer 1 testing, signal and spectrum analysis and signal generation. R&S FSQ, R&S FSP and R&S FSU signal and spectrum analyzers, R&S SMU200A, R&S SMJ100A and R&S SMATE200A signal generators, and layer 1 test software for the R&S CRTU-W and R&S CRTU-M are equipped with HSUPA functionality. The company already offers a complete range of HSDPA T&M equipment.

HSUPA will provide the same advantages for the uplink that HSDPA already does for the downlink – increased data rates and throughput and reduced access times. Data rates of several Mbit/s will also be possible with HSUPA. For subscribers, the combination of HSDPA and HSUPA considerably shortens the access times to an application. To support manufacturers of user equipment (UE) and network components in developing HSUPA solutions, Rohde & Schwarz has already adapted some of its T&M instruments to the new requirements. In addition, the company is actively involved in creating HSDPA and HSUPA test cases on the ETSI standardization committee.

For the R&S CRTU-W and R&S CRTU-M protocol testers, Rohde & Schwarz has added the new standard to its layer 1 test software. Besides HSDPA, the test software now also supports tests on layer 1 implementations for HSUPA user equipment. The test software simulates the layer 1 behavior of a base station. It can generate complex HSUPA downlink signals at layer 1 and test their reception and processing in the layer 1 UE implementation under test.

The test software provides many possible configurations for the transport channels defined in HSDPA and HSUPA as well as for the physical channels. An additional scripting interface facilitates the automated execution of test scenarios.

For the R&S FSQ, R&S FSP and R&S FSU signal and spectrum analyzers, Rohde & Schwarz has added HSUPA to the R&S FS-K72/-K73/-K74 application firmware packages. Besides HSDPA, they thus provide comprehensive functions for transmitter measurements on HSUPA base stations and modules. Firmware R&S FS-K74 is integrated into R&S FS-K72 and makes it possible to test modulation for HSDPA and HSUPA signals in the downlink. HSDPA and HSUPA signals in the uplink are covered by R&S FS-K73.

For the vector signal generators of the R&S SMx family, the R&S SMx-K45 software option provides an HSUPA update. The R&S SMU200A, R&S SMATE200A and R&S SMJ100A can thus generate HSUPA signals for measurements on base stations, modules and UE. The R&S SMx K45 features channel coding and also makes the fixed reference channels defined in the 3GPP standard available to the user. HSDPA signals in the uplink and downlink can be generated with the R&S SMx K43 options.

The HSUPA T&M solutions for layer 1 testing, signal generation and signal and spectrum analysis are now available from Rohde & Schwarz.
