Abstract

Microwave ovens are potential interference sources to personal wireless systems utilizing the 2.4 GHz ISM band. Hence, the effects of indoor multipath environment are investigated on the propagation of electromagnetic noises emitted from microwave ovens. Theoretical and experimental analyses are conducted employing a time-domain model of the microwave oven noise. The results indicate that the multipath propagation generally emphasizes an oven noise as compared with a CW signal, especially in wide band wireless systems, which may deteriorate the link quality seriously.
