RF Electromagnetic Fields Exposure Monitoring using Drive Test and Sensors in a French City

This paper presents the monitoring work on radiofrequency (RF) electromagnetic field (EMF) exposure, carried out in a French city by using drive test and sensor network methods. The drive test measurements are realized by continuously measuring in a car via a portable spectrum analyzer, i.e., Tektronix RSA 306B, connected to a 3-axis antenna. It records electric (E) field values over a broad cellular band (700 MHz – 3.8 GHz) along the pre-defined outdoor routes at a height of 2 meters above the soil level. Secondly, a total of 19 sensors are installed near the center of the city, on the streetlamps (4 meters to the soil), which measure the broad band (250 kHz – 6 GHz) exposure level. The statistical distribution of measurement data is analyzed, and compared with base station antenna (BSA) information, which can be publicly accessed. Furthermore, the temporal variation of measurements collected by sensor networks is analyzed.
