Afin de déterminer la conformité de l'exposition aux champs électromagnétiques provenant de l'antenne d'une station de base dans la région du champ lointain, nous devons calculer la valeur du champ moyenne spatialement dans un espace défini. Cette valeur est calculée sur la base de la valeur mesurée obtenue en plusieurs points dans l'espace restreint. Selon les lignes directrices de l'ICNIRP, en chaque point de l'espace, les niveaux de référence sont moyennés sur 6 minutes (de 100 kHz à 10 GHz) pour le grand public. Par conséquent, plus nous utilisons de points, plus le temps de mesure est long. Pour une application pratique, il est très avantageux de consacrer moins de temps à la mesure. Dans cet article, nous avons analysé la différence des valeurs moyennes entre des périodes de 6 minutes et moins et l'avons comparée à l'incertitude type pour la dérive de mesure. Sur la base de l’écart type par rapport à la valeur moyenne de 6 minutes, la durée moyenne minimale proposée est de 1 minute.

Abstract: In order to determine exposure compliance with the electromagnetic fields from a base station's antenna in the far-field region, we should calculate the spatially averaged field value in a defined space. This value is calculated based on the measured value obtained at several points within the restricted space. According to the ICNIRP guidelines, at each point in the space, the reference levels are averaged over any 6 min (from 100 kHz to 10 GHz) for the general public. Therefore, the more points we use, the longer the measurement time becomes. For practical application, it is very advantageous to spend less time for measurement. In this paper, we analyzed the difference of average values between 6 min and lesser periods and compared it with the standard uncertainty for measurement drift. Based on the standard deviation from the 6 min averaging value, the proposed minimum averaging time is 1 min.
