Electromagnetic field evaluation on an antennas shared site

The last two decades have seen a strong technological development in the area of wireless voice and data transmission, thus adding new sources of electromagnetic fields in the urban environment besides existing FM radio and TV broadcasting. There are situations in which one site is used by multiple technologies emitting in different frequency bands and with different powers. The paper presents the results and methodology employed in measuring and evaluating electromagnetic field exposure on a building rooftop, where TV and FM radio broadcast stations coexist with GSM, IS-95, UMTS and WiMAX base stations, microwave links and different data communication technologies.
