In June 2016, with the aim of ensuring a global improvement in the performance of the Italian System of the Environmental Agencies (SNPA) and its homogeneity on the national territory, an intercomparison circuit (IC) was planned and conducted concerning the measurements of electromagnetic fields associated with Long Term Evolution (LTE) mobile communications, which were very recently introduced at that time. The intercomparison circuit, designed and built according to the criteria of ISO 17043, was organized as part of a consolidated collaboration between the Institute for Environmental Protection and Research (ISPRA) and the Piedmont Regional Agency for Environmental Protection (Arpa Piemonte). The results obtained, preceded by a brief description of the entire process of organization and analysis, are the subject of this work. The IC covered in particular: the narrow band measurement procedures used in the field; the choice of decoding, measurement and extrapolation of the synthesis result; the response of the instrumentation, limited to the models in the field. The site chosen by the organizers, primarily characterized through measurements and theoretical evaluation of the field, is the roof of the Lingotto Building in Turin. A total of 27 groups participated in the circuit: 25 SNPA departments (including the organizers Arpa Piemonte and ISPRA) and 2 private labs. All participants provided the results. The outcome of the comparison was decidedly positive: only 2 participants, for whom a joint assessment of possible causes will also be illustrated (according to ISO 5725:2), achieved significantly different results.
