performance) to create a baseline performance threshold. Te power level of the wanted signal is reduced to the point where communications is just barely possible (10% PER on the wanted system), to reproduce the worst-case scenario or cell-edge conditions. Aſter the interfering signal is activated, measurements are repeated. If the DUT generates visual and/or audio
output, the inspection soſtware monitors the DUT using an HD webcam and microphone to check whether the outputs have the desired quality. Deviations are documented with a timestamp and evidence data. A spectrum analyser monitors the RF
spectrum during the measurement process. Te spectrum analyser can be used to check whether the wanted and interference signals have the right frequencies and levels, and whether any external signals are present that could invalidate the test result.
Interference-free coexistence Ensuring interference-free coexistence of radio products will grow even more important in the IoT era. Rapid technological
