As part of its missions to monitor public exposure to electromagnetic waves, the French national frequency agency (ANFR) has launched an extensive measurement program at nearly 2 000 sites to assess exposure following the deployment of the new 5G mobile technology starting in late 2020. For each site identified in the program, an initial measurement is performed before the addition of 5G on these sites, a second and third measurement are performed at about 4 months and 8 months of operation in order to monitor the evolution of exposure according to the operational deployment and traffic growth. The measurements are carried out according to the ANFR protocol referenced in the French official journal, which is the reference text for accredited laboratories that carry out field measurements (E in situ). In addition to the global and detailed frequency exposure measurements, specific measurements were performed by downloading a 1 GB file on the 3 500 MHz band. This procedure allows to artificially generate additional traffic corresponding to the exposure indicator proposed by ANFR for steerable beam antennas and allows to estimate the local exposure level that would be statistically reached in the long term in 5G.
