A certification of radio products for the Brazilian market is based on an approval of the local authority Agência Nacional De Telecomunicações (Anatel).

In November 2018, the Authority published a communication on test requirements for radio products. One of the results of this communication is that the number of necessary tests for WLAN products with additional radio technologies will be reduced.

Anatel explained that RF radiation immunity according to IEC 61000-4-3 does not have to be applied to every WLAN technology, but only in the most complex modulation, with the highest burn rate for each frequency band.

An example is a device with WIFI 802.11 b/g/a/n/ac + Bluetooth (EDR+LE) + NFC technology. This results in the following reduced test scope:

Frequency	Technology	Required Testing of RF Radiated Immunity
		Before	New
2.4 GHz	BT EDR	Required	Required
2.4 GHz	BT LE	Required	Not Required
2.4 GHz	802.11 g	Required	Not Required
2.4 GHz	802.11 b	Required	Not Required
2.4 GHz	802.11 n20	Required	Not Required
2.4 GHz	802.11 n40	Required	Required
5 GHz	802.11 a	Required	Not Required
5 GHz	802.11 n40	Required	Not Required
5 GHz	802.11 ac80	Required	Required
13 MHz	NFC	Required	Required

 

The number of prescribed tests is thus reduced to four.
