New study of Electro-Magnetic Effects of the Power Line on the Mobile Phone Handsets

In this paper we studied the analytical and experimental effect of the electromagnetic fields produced by the power lines on the mobile phone circuits. Indeed to study this EMC problem two main techniques’ are used; the first one is the image theory which treats the problem from the electrostatic point of view and the second one is inspired from the faraday law to explain the problem as a magnetic circuit leading to a mutual inductances between the electromagnetic fields produced by the power line and the mobile circuit. For these, we introduce, the analytical transmission line modeling of the mobile telecommunication system located in a disturbed EM environment. The effect of this environment on the characteristics of these circuits is systematically clarified in permanent mode. The obtained results, shows the correlation between the presence of the electrical power line system and the electrostatic and magneto static effect on the mobile phone circuits, and to develop the principal characteristics in term of the quasi-static potential, and the electromotive force induced in the multi-conductor transmission line, and we used a plate form of measurement Nemo Outdoor which enabled us to raise a group of indicators: Mobile Station Power (MSP), Received signal power level (RxLevl), Received signal quality (RxQual).
