On March 1st, 2019, ANATEL published its Act No. 1379. This is an update to the Technical Requirements for Conformity Assessment of Restricted Radiocommunication Equipment. There were some changes on items 6.2.5, 13.1 and 13.1.1 of Annex I to Act No. 14.448 of December 4/2017.
The changes were regarding specific conditions of use of the Periodic Operation Device with periodic transmission characteristics and the limit of the electric field strength of the Radio Frequency Identification System (RFID) in the 13 MHz band.
Here is a sum-up on these items:
1. 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.
2. 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, 902-907.5 MHz, 915-928 MHz, 2,400 – 2,483.5 MHz and 5,725 – 5,850 MHz shall meet the limits set forth in Table V (you can see the attached pdf for more reference).
3. 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.
