On November 25, 2024, the EU formally approved ETSI EN 301 893 V2.2.1, with mandatory enforcement required by February 29, 2028. During the transition period, as this version has not yet been cited in the EU Official Journal (OJ), certification testing is still recommended based on the previous version, ETSI EN 301 893 V2.1.1.
Significant Technical Changes Compared to the Previous Version Include:
01: Incorporation of Wi-Fi Band 4 (5725 – 5850 MHz) into the standard. Devices operating in this band can now be certified using ETSI EN 301 893, whereas they were previously typically certified under ETSI EN 300 440.
02: Division of the 5150 – 5350 MHz band into Sub-band 1 and Sub-band 2. Test channel requirements in Section 5.3.2 are adjusted, mandating independent evaluation of both sub-bands. Parameters like power, power spectral density, and in-band masks must be assessed on both the lowest and highest channels within each sub-band.
03: Introduction of new in-band mask testing requirements for multi-channel operation in Section 4.2.4. Appendix I also adds examples of multi-channel operation masks.
04: Changes to the Adaptive Detection Threshold; however, the standard does not explicitly provide detailed information on these specific changes.
05: Addition of Receiver Blocking Criteria in Section 4.2.8.3. For products not supporting Bit Error Rate (BER) measurements (e.g., wireless audio products), blocking performance can be assessed based on normal transmission functionality.
06: Introduction of Adjacent Channel Selectivity test requirements in Section 4.2.9.
Scope of Products Covered by This Standard
This standard applies to Wireless Access Systems (WAS) used in Wireless Local Area Networks (WLANs) and devices communicating directly with each other via ad-hoc networks. It is relevant to radio equipment operating in the 5 GHz band.
