BARCELONA , Mobile World Congress, February 13 /PRNewswire/ --     When used as an LTE protocol tester, the R&S CMW500 delivers
multiple benefits to chipset and wireless device manufacturers - in every
phase of UMTS LTE-compliant protocol development. Benefits include
significant cost reductions for the entire development of UMTS LTE wireless
devices because the protocol stack can be checked at an early stage.
Furthermore, the protocol tester reduces time to market since hardware and
software can be co-developed, tested and fine-tuned simultaneously.

Building on Rohde & Schwarz's reputation for leading-edge UMTS
LTE protocol stack testing, this powerful hardware solution provides a
frequency range up to 6 GHz and a bandwidth of 40 MHz. The R&S CMW500 for LTE
also extends its benefits to later stages in the lifecycle of products, when
it can be used in conformance, performance and interoperability tests. An
alternative software solution for PCs supports the individual developer
starting at the protocol development phase.

Predefined test sequences significantly reduce development
effort. Easy-to-operate programming interfaces let designers adapt these test
sequences to the requirements at hand or to create an entire set of their
own.

A full suite of tried-and-true software tools are available
for running test sequences: Project Explorer software begins by configuring
the test run and managing the results; Message Analyzer analyzes the protocol
layers. The high level of detail provided by the R&S CMW500 for LTE enables
designers to immediately detect any problems in the protocol stack. Since all
tests are fully automatic, a large number can be performed in a short time.

In the PC-based solution, the physical layer is emulated by
software to which the protocol stack of the UMTS LTE wireless device is
linked. With this model, the tester and protocol stack run on a PC without
extra hardware and the tester can be installed on the desktop PC to perform
tests. This greatly simplifies the later integration of protocol software,
baseband chips and RF modules. When the software solution is retrofitted to
the hardware solution as required for integration, all test sequences remain
unchanged and available.

The R&S CMW500 for LTE provides detailed information about how
precisely the protocol of the wireless device meets the 3GPP specifications.
Featuring a frequency range up to 6 GHz and a bandwidth of 40 MHz, the
architecture of the R&S CMW500 for LTE can easily handle evolving wireless
standards. Future versions will accommodate complex scenarios including MIMO,
multiple radio cells, and inter-RAT functionality as well as higher data
rates and a digital I/Q interface. These features give the platform the
ability to test the protocol stack in conjunction with IP-based applications
such as file transfer or Internet browsing on the wireless device.

Rohde & Schwarz offers a complete product portfolio for the
development of UMTS LTE wireless devices. The products include power meters,
spectrum analyzers, signal generators, mobile radio testers, protocol testers
and an RF conformance test system. Manufacturers can rely on Rohde & Schwarz
products and expert support from start to finish. Specially trained
application engineers from the worldwide Rohde & Schwarz support network
provide the full range of customer assistance.

The R&S CMW500 for LTE can now be ordered from Rohde & Schwarz.
