ANATEL published Act 2311 right before the scheduled start of the new mandatory radiated tests of transceiver equipment (WiFi, BT) in Brazil, test which were dictated by Act 14448. This means that for another 3 months, or until ANATEL concludes their study on the matter, these additional tests are not required.
