A new hybrid algorithm to evaluate the field strength levels around base stations antennas of cellular mobile radio systems is presented in the paper. The method allow a correct evaluation of near and far radiated field by means of the combination of different propagation models. The field intensity level is compared with measurements for some typical urban base stations and an analysis of the impact of the presence of buildings or other objects is also performed. We identify the areas around the antennas where the field strength level exceeds the exposure limits specified in [1, 2]. As a result of this analysis we propose a preliminary classification of different installations based on few fundamental parameters related to the antenna characteristics and to the environment topology. © 1999 IEEE.

Abstract
A new hybrid algorithm to evaluate the field strength levels around base stations antennas of cellular mobile radio systems is presented in the paper. The method allow a correct evaluation of near and far radiated field by means of the combination of different propagation models. The field intensity level is compared with measurements for some typical urban base stations and an analysis of the impact of the presence of buildings or other objects is also performed. We identify the areas around the antennas where the field strength level exceeds the exposure limits specified in [1, 2]. As a result of this analysis we propose a preliminary classification of different installations based on few fundamental parameters related to the antenna characteristics and to the environment topology. © 1999 IEEE.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
