France’s spectrum agency ANFR has released the preliminary results of radio frequency (RF) exposure measurements collected at several 5G pilot sites using 3.5 GHz spectrum. Across a sample of 43 sites, it found that RF exposure values were well below the limit of 61 V/m set for the 3.5 GHz band, while noting that the level of usage significantly impacted the values recorded.
In a summary table, the agency published values taken under three main sets of conditions, including an extreme scenario with maximum emissions and the exposure measured with no traffic exchanged.
In a third usage case, measurements were taken during the transmission of 1 GB of data in a given direction, with results ranging from 0.8 to 1.6 V/m across different pilot sites. The agency is proposing to adopt this third case as a predictive model indicator, explaining that it will be integrated into the forecasts currently under development to estimate exposure under real conditions.
