This study was conducted by ANACOM in 2020 to assess the impact of 5G in terms of the general public’s exposure to electromagnetic fields. It presents the results of measurements taken in Portugal between June and October 2020 in the vicinity of stations used to carry out 5G pilot trials in the 3.4 - 3.8 GHz (3.6 GHz) band; these trials were authorised by ANACOM, within the scope of its powers and responsibilities.
The main conclusions of the study are as follows:
- The 5G networks were operating in accordance with expected requirements with respect to the 3.6 GHz band.
- Overall, the measured values were more than 50 times lower than the international reference levels recommended by the World Health Organization.
- The contribution of the trial 5G networks in the 3.6 GHz band to total levels of exposure was very insignificant at the time of measurement when compared to the mobile networks already in operation.
