the localized, peak SAR10g is evaluated for the six different configurations shown in Fig 4 and compared to the ICNIRP basic restrictions on the peak SAR10g for the general public, which are 2 W/kg for the head and trunk and 4 W/kg in the limbs. Table 1 lists the peak SAR10g values obtained from the FDTD simulations, renormalized to an input power of 1 mW. All values are far below the ICNIRP basic restrictions on peak SAR10g. Corresponding to these low SAR10g values, we find, using Equation 1, relatively high allowed input powers (>0.29 W, see Table 1) in comparison to the 1 mW input power, which is applied in the standard transmission protocol. The |S11| of the studied antenna is located between -19 dB and -14 dB at 3.5 GHz, depending on the studied configuration. DISCUSSION In this study, the RF exposure near an attocell is studied using both compliance measurements and numerical simulations. In order to execute numerical simulations, the studied attocell and the antenna it contains, see Fig 1 and 2, have to be modeled in the simulation software under consideration. The antenna model is based on the real and dielectric antenna’s dimensions parameters. The feed was modeled as a voltage source, whereas this is an SM-A antenna’s connector in reality, see Fig 2. Figure 5 shows that this model has yielded a good agreement in the S11 between the FDTD simulations and the measurements of the S11 in antenna’s An additional validation was executed using MoM, which was in good agreement with the FDTD simulation and the measurement in terms of the first peak of resonance of the antenna
