The Brazilian National Telecommunications Agency (ANATEL) published Act Nº 1379. The Act changes the provisions regulating the technical requirements for periodic transmission devices and the limit of the electric field strength of the Radio Frequency Identification System (RFID) in the 13 MHz band.

Section 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 instead of the original 1 second per hour, for each transmitter.

Table V of Section 13.1 – Includes new limit values for the 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, 902-907.5 MHz, 915-928 MHz, 2,400 – 2,483.5 MHz and 5,725 – 5,850 MHz.

Section 13.1.1 – Specifies 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.
