INVESTIGATION OF TIME AND LOCATION DEPENDENT ELECTROMAGNETIC FIELD RADIATION OF MOBILE PHONES

Mobile phone is an electromagnetic wave transmitter. Most of mobile phones in European Union are connected to GSM network which uses 900 MHz and 1800 MHz frequency. This means propagation of high frequency and short length electromagnetic waves. Mobile phone users feel irradiation of electromagnetic field. The phone radiates electromagnetic waves differently in different mode of operation. Analysis of irradiation from mobile phone is necessary evaluating negative effects of low frequency electromagnetic fields and their impact on a human body. Results of mobile phone wave power measurements are presented in this article and field strength changes of the electromagnetic field related to the measurement's location and distance from the transmitter tower are discussed.
