ANATEL released the Official letter 112 recently.
SAR was required for portable devices working close to the body (≤ 20cm) and operating within the range of 300 MHz to 6GHz before. The Act 1630 announced on Mar. this year changed the range from 4 MHz to 6GHz. But so far, none labs have capacity to test SAR in frequencies lower than 300MHz.
Due to the lack of local labs, ANATEL will not request SAR for devices operating within 4 to 300MHz range until Mar 31st, 2022 in the Official letter.
