“…Basically, the field level depends on two factors, namely, the path loss between the RBS and the field point, and the RBS antenna gain in all directions. To calculate the electric field levels in any desired position, the following far-field equation was used [25]…”

“…For this reason, we must compute the field amplitude Ep for each RBS using the previous formula and then add the corresponding power density, since the fields of different RBSs are uncorrelated. Therefore, the total EM field is obtained using [25]…”

“…It is therefore necessary to derive the entire radiation pattern. Among the available methods, in this work, the gain of the transmitting antenna is used as input to the 3D interpolation algorithm from [25,26] in order to derive the full pattern and hence calculate the field levels in a given point. An explicative scheme of the reconstruction procedure is shown in Figure 1 for the case of a Kathrein 742212 antenna.…”

“…It is possible to overcome the aforementioned limitations of the C231WI model by rephrasing and redefining the model parameters, as done in [25]. Instead of using the mean value of the buildings in the grid of interest, h roof should be defined as the mean of the height of the buildings which are crossed by the propagation path, considering the segment which joins the RBS antenna and the ground below the mobile, as shown in Figure 2a [4].…”

The knowledge of the electromagnetic field levels generated by radio base stations present in an urban environment is a relevant aspect for propagations and coverage issues, as well as for the compliance to national regulations. Despite the growing interest in the novel fifth generation (5G) technology, several aspects related to the investigation of the urban propagation of the Global System of Mobile Communication (GSM), third generation (3G), and fourth generation (4G) mobile systems in peculiar non-rural environments may be improved. To account for irregular geometries and to deal with the propagation in hilly towns, in this work we present an enhanced version of the COST231-Walfisch–Ikegami model, whose parameters have been modified to evaluate the path loss at distances greater than 20 meters from the radio base station. This work addressed the problem of providing an effective, reliable, and quantitative model for the estimation of electromagnetic field levels in built-up areas. In addition, we also developed and tested a pre-industrial software prototype whose aim is to make the estimated electromagnetic field levels available to the key players in the telecom industry, the local authorities, and the general population. We validated the proposed model with a measurement campaign in the small urban and irregular built-up areas of Dorgali (Nuoro), Cala Gonone (Nuoro), and Lunamatrona (Cagliari) in Sardinia (Italy).

Determination of the levels of the electromagnetic field of frequency between 0 Hz and 300 GHz bands in the working area and the evaluation of the results measured in terms of international standards is now essential according to the regulation of working safety and health. In this study, electromagnetic field measurements were performed in a cleaning product manufacturing factory with 400 workers. Electric and magnetic field measurements were performed at 10 different departments of the factory with extremely low-frequency and broadband (radiofrequency) frequencies. Obtained values are shown and analysed with graphs and compared by the International Commission on Non-Ionizing Radiation Protection and National Information Technology and Communication Authority (Turkey) limits. Also, an assessment is made for the occupational electromagnetic field levels in the factory and recommendations are suggested for the lowest risk occurrence and providing a healthier working environment for workers.
