5G, IoT pose new challenges to testing
With test automation being a burning issue, 5G radio networks in the transition from the embryonic to the fetal phase and the Internet of Things taking shape, manufacturers of test equipment are active in a terrain mined with technology decisions that need to be taken but many uncertainties as to which direction the markets will develop. EE Times Europe discussed these issues with Jonathan Borrill, Director of Market Strategy at RF test technology provider Anritsu.
Thus, those ten seconds of setup time can be reduced to milliseconds of setup time - which makes a massive improvement in test time. Thus, you can cut down a mobile phone production test from three minutes down to 20, 30 seconds.

eeNews Europe: Is 5G communications technology already something that affects your developments?

Borrill: We are starting to see the first requirements and basic technical directions of 5G. We see that millimetre wave backhaul is requiring more advanced high-performance testing, we expect wider bandwidth modulation schemes, wider bandwidth for signal generators or for signal analysers.

eeNews Europe: are there different modulation schemes compared to current-generation mobiles?

Borrill: At the moment there are several different schemes being evaluated by different companies and being proposed. But even the standards body for 5G has not selected a waveform yet, and part of that is that even the operators haven't set the requirements yet. We don't even have a requirements document for 5G. We certainly don't have a standard of what waveform will be used. Many universities and research institutions are investigating different waveforms. There are several waveform candidates that seem very popular at the moment. We also don't know exactly which ones will be chosen in the end but there are some clear candidates which we are looking at. One of them is called FBMC - Filter Bank Multi-Carrier. This is probably the top technology that has been discussed as a waveform, and then there are some variations on that as well.

eeNews Europe: Does the 5G development already has an influence to your business?

Borrill: We are certainly excepting the business to start this year. If we look at the research projects in the industry, it is starting from now. The fundamental research in terms of waveforms, modulation, devices, wider bandwidth of device, higher sensitivity devices - all this fundamental research takes place now.

eeNews Europe: Are there any flagship projects
