Measuring Radiated Spurious Emissions from a 5G Device in a Reverberation Chamber

As more 5G devices become available, emissions testing will be increasingly important to ensure devices do not interfere with each other. As devices become more integrated, it may not be possible to perform conducted emissions tests. Current standards for 5G include conducted and over-the-air test methods for radiated emissions, but limit the frequency ranges the test methods can be used on. In this paper, we show that the current conducted requirements can be measured over-the-air in a reverberation chamber with good margin. An uncertainty estimate for the reverberation chamber method is included and shows that the reverberation chamber method already meets the current uncertainty requirements for spectrum emission mask and spurious emission measurements.
