For the purpose of EMC immunity and people exposure, we have studied the radiation characteristics of various electronic devices widespread used by the public. During the first phase, we have identified typical electronic devices found at residences and offices (microwave ovens, wifi routers, walk- talkies, mobile phones, cordless phones, Bluetooth devices etc.). During the second phase, we have defined measurement protocols based on specific measuring equipment to study the radiation properties of such devices. One of the great challenges of this work was to provide efficient measurement protocols that could enable the evaluation and comparison of a large range of systems, taking into consideration their particularities. Mostly here, the RF emissions have been analyzed seeing the influence of measurement parameters on the study of various complex radiated signals.
