MAERNI - Módulo de avaliação da exposição à radiação não ionizante proveniente das antes de transmissão de TV digital e rádio FM para uma ferramenta com o ambiente virtual 3D

Abstract

In recent years given the technological advancement of the communication media, and the increasing of users demand who wants a high quality of these services offered to them, the companies have increased the number of Radio Base Stations in cities, where many of these are located in environments with high housing density. Considering that each antenna or set of antennas present in these stations have an electromagnetic field of radiofrequency and transmit radiation, the concern with the population living in the adjacency of the transmitting antenna is the studies object of systems than regulate the companies that offer radiofrequency services, as well as, is the object of studies that aim not only to discover the effects of the contact with the ionizing and non-ionizing radiation present in these fields, but also to find out if the standard established for the regulation of services is being fulfilled. In this work presents the stages of development of a module, which consists of an extension added to the simulator for planning mobile communication networks (SIMPLARCOM). The module proposed allows, through the Virtual Reality environment (VR), to build and configure different scenarios, as well as the parameters of the transmission antenna, to provide an environment for non-invasive tests to evaluate non-ionizing radiation exposure; and identify potential insecure areas for housing, providing information for aid in decision-making regarding the relocation of transmitter antennas and aiming to decrease the ERP (effectively radiated Power) radiated by these Antennas. The module considers the guidelines present in resolution Nº. 303, published by the National Telecommunications Agency (ANATEL). In the results obtained is possible, navigate through the constructed scenario and check the value of the received power, the field intensity, the operation frequency, the antenna being analyzed and whether a certain point in the scenario is or is not receiving radiation at according to the threshold permitted by ANATEL.
