Early checking cuts wireless costs

The R and S CMW500 reduces time to market since hardware and software can be codeveloped, tested and fine tuned simultaneously.

When used as an LTE protocol tester, the R and S CMW500 provides chipset and wireless device manufacturers with 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 codeveloped, tested and fine tuned simultaneously.

The system provides a frequency range up to 6 GHz and a bandwidth of 40MHz.

The R and S CMW500 can also be used in later stages of the lifecycle of products, 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 their requirements or create an entire set of their own.

A suite of software tools is available for running test sequences.

Project Explorer software begins by configuring the test run and managing the results and Message Analyser analyses the protocol layers.

The high level of detail provided by the R and 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 and S CMW500 for LTE provides detailed information about how the protocol of the wireless device meets the 3GPP specifications.

It offers a frequency range of up to 6GHz and a bandwidth of 40MHz and 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.
