Brazil – Regulations for human exposure to electrical, magnetic and electromagnetic fields

Anatel has published Act 1379 of February 28, 2019, which modifies the technical requirements for conformity assessment of restricted radiated Radiocommunication equipment. This new Act changes the following sections of Annex I of Act 14448 (December 4, 2017).

    • Section 6.2.5 Periodic transmissions – Increases the periodic transmission rate to 2 seconds per hour.

6.2.5. Periodic transmissions at predetermined regular intervals are only permissible in supervisory or scan transmissions to determine the systemic integrity of transmitters used in safety applications. In this case, the periodic transmission rate shall not exceed 2 (two) seconds of duration per hour for each transmitter.

    • Section 13.1 RFID systems – changes the table of limits applying to 13.41 to 14.01 MHz

13.1. Radio Frequency Identification Systems (RFID) operating in the bands 119 – 135 kHz, 13.11 – 13.36 MHz, 13.41 – 14.01 MHz, 433.5 – 434.5 MHz, 860 – 869 MHz, 894 – 898.5 MHz, 902 to 907.5 MHz, 915-928 MHz, 2400 to 2483.5 MHz and 5725-5850 MHz must meet the limits defined in Table V .

119 – 135 kHz 2.400 / F (kHz) 300
13.11 – 13.36 106 30
13.41 – 13.553 334 30
13.553 – 13.567 15.848 30
13,567 – 13,710 334 30
13,710 – 14.01 106 30
433.5 – 434.5 70,359 3
860-869 70,359 3
894 – 898.5 70,359 3
902 – 907.5 70,359 3
915 – 928 70,359 3
2,400 – 2,483.5 50,000 3
5,725 – 5,850 50,000 3
    • Section 13.1.1 RFID systems – requires that the most restrictive field strength value is applied at band transition frequencies.

13.1.1. The field strength limits shall be measured using the mean detector and at the band transition radio frequencies the most restrictive field strength value shall be applied.
