Canada Introduces ETSI EN 301 893 V2.2.1 for DFS Requirements
Innovation, Science and Economic Development Canada (ISED) published Notice 2025-DRS0006 on 10 September 2025, proposing the adoption of ETSI EN 301 893 V2.2.1 (2024-11) for 5 GHz WAS/RLAN radio spectrum access. Following the consultation, ISED introduced a six-month transition period ending on 20 July 2026.
Until this date, manufacturers using the ETSI-based test procedure may demonstrate compliance with Dynamic Frequency Selection (DFS) requirements using either ETSI EN 301 893 V1.8.1 or V2.2.1. After the transition period, new certifications using the ETSI procedure must apply ETSI EN 301 893 V2.2.1. FCC KDB 905462 remains an accepted alternative, except for devices operating in the 5600–5650 MHz band, where only the ETSI EN 301 893 procedure is accepted. The revised ETSI standard provides additional information for client devices with radar detection capabilities.
This update applies to products subject to the DFS requirements of RSS-247, Issue 4, particularly devices operating in the 5250–5350 MHz and 5470–5725 MHz bands. Affected products may include access points, multimedia systems, and automotive infotainment devices.
