Texas Instruments’ Wi-Fi wireless portfolio [2] consists of Wi-Fi MCUs, Wi-Fi Network processors and Certified Wi-Fi modules, which support the operation in both 2.4 GHz and 5 GHz frequency bands. In most cases, they are used inside the unlicensed or license-free frequency bands. Unlicensed means only that the user of these products does not need an individual license from the telecommunication regulatory authorities for the use of the frequency band. Unlicensed does not mean unregulated; the wireless product itself usually needs to meet strict regulations and to be certified by the appropriate regulatory authorities.
International regulations and national laws regulate the use of radio equipment. Although the operation of radio equipment in the 2.4 GHz and 5 GHz bands are license-free, the final product itself has to be type approved. Note that the type approval is not required for the Chips (ICs) by itself but rather the actual application of an end product requires type approval. For CE regulations for SRDs operating in License–Free 2.4 GHz and 5 GHz frequency bands and type approval procedure, see CE Regulations for SRDs Operating in License-Free 2.4 GHz/5 GHz Bands [1]. Also, for the appropriate ETSI and local documentation related to the product, see [1].
This application note is a summary of the CE Conformity test requirements and test procedures for Wi-Fi devices which operates in both 2.4 GHz and 5 GHz bands. The CE Conformity test requirements for Wi-Fi devices are shown in Table 2-1 and the test procedure for TI’s Wi-Fi devices (CC3x20, CC3x35, CC3100 and CC3200) are covered in Section 2 through Section 7. For a complete understanding of CE Regulations and its test procedure, see CE Regulations for SRDs Operating in License-Free 2.4 GHz/5 GHz Bands [1] along with this application report.
