Abstract:
Electromagnetic compatibility is the ability of systems or equipment to be tested in the intended environment through levels of efficiency without degradation caused by electromagnetic interactions. Compliance with safety limits requires tests to measure the device when operated at w maximum power maintained over an average period of time. However, the average transmitted power of many of these devices depends on a range of system parameters, such as power control and others. Several agencies now require these devices to be subjected to safety limit tests, but are faced with the problem of a lack of standardized assessment procedures. This is a cause of anxiety among agencies, industry and consumers. The objective of this study is to examine procedures that can determine the maximum permissible exposure to radiation and that are scientifically and technically sound. Compliance with standards can be investigated on the basis of Specific Absorption Rate (SAR) measurements and derived quantities, i.e, the electric field and magnetic field. In this study, compliance with the electric field was carried out through the development of simulations, to aid in the evaluation of the exposure of populations that currently are (or will be) the subject of digital TV services in the frequency range of 599 MHz.
