Electromagnetic fields evaluation by means of standard algorithms and cartographic data. Broadcast case into urban environment

Characteristics of available data and choice of algorithms are the main parts of evaluation activities that use software simulation to resolve any one territorial intervention and to survey environmental impact. Our paper investigates how urban data in a standard format and for very wide purposes (Cartesia applications), together with algorithms of electromagnetic field calculations, can be involved in these activities. The algorithms are the same as those certified by the international regulator, the ITU (International Telecommunication Union) that includes two consultative bodies for telephony (CCITT - Comité Consultatif International de Téléphonie et de Télégraphie) and radio-communications (CCIR- Comité Consultatif International de Radiocommunicaton), but they are adapted to specific problems. In the last few years, the large development of wireless communications has accelerated electromagnetic propagation studies that should solve urban area aspects. In effect, the broadcast problem involves, with conflicting requirements, people health management, energy distribution and availability of point-area communication channels. Consequently, the legislator has imposed rules on the limits of electromagnetic field values and protocols of evaluation criteria for maximum exposure to radiation. Our paper aims to put in evidence some technical aspects included into the evaluation of effects originating from telecommunication plant implementation or modification. Our paper describes the inclusion method of building data and special algorithms that implement the rules and recommendations of the ITU. Finally, results of some case studies are shown.
