ETSI EN 301 893

ETSI EN 301 893 is a European harmonized standard for broadband radio access networks, including 5 GHz radio local area network (RLAN) equipment. Its principal frequency ranges are 5 150–5 350 MHz and 5 470–5 725 MHz. When correctly applied, the standard can provide a presumption of conformity with the radio-spectrum access requirement in Article 3(2) of the Radio Equipment Directive (RED) 2014/53/EU for the requirements covered by its cited reference. It does not by itself demonstrate compliance with every RED requirement.

Scope and application

The technology-neutral scope includes equipment such as:

• access points and routers

• Wi-Fi clients, including laptops, tablets and smartphones

• point-to-point and point-to-multipoint bridges operating as WAS/RLAN equipment

IEEE 802.11a/n/ac/ax devices are common examples, but the standard is not limited to these technologies. European frequency ranges and operating conditions should be used when assessing EU compliance; the US U-NII designations are not the regulatory band names used by the standard.

Annex B also addresses operation in 5 725–5 850 MHz. Use of this additional range depends on the national frequency allocation and applicable installation or operating conditions in the country where the equipment is used.

Key technical requirements

• Transmit Power Control (TPC): where TPC is implemented, the power-control range is at least 6 dB. Operation without TPC is possible under specified reduced power limits; the separate 3 dB value relates to the required aggregate power reduction, not to the minimum TPC control range.

• Dynamic Frequency Selection (DFS): DFS requirements apply in the 5 250–5 350 MHz and 5 470–5 725 MHz ranges. Radar detection, channel-availability checks and channel-move behavior depend on the equipment role and operating mode; not every client device performs independent radar detection.

• Channel access: adaptivity requirements define how equipment assesses and accesses the medium. The applicable procedure depends on the operating mode and includes defined provisions for exceptions and short control signalling.

• Power and emissions: the standard specifies maximum power levels and limits for unwanted transmitter emissions within and outside the operating band.

• Occupied bandwidth: nominal channel bandwidth and occupied channel bandwidth are distinct parameters. Their relationship is assessed using the applicable definitions and procedures rather than a simple equality rule.

Version and EU citation

The current published edition is ETSI EN 301 893 V2.2.1 (November 2024). It includes provisions for flexible spectrum use and multi-channel operation. Its treatment of 5 725–5 850 MHz is subject to the national conditions described above.

EN 301 893 V2.2.1 has been cited as a harmonized standard in the Official Journal of the European Union since 15 May 2025. The published ETSI EN 301 893 V2.2.1 edition of November 2024 is the appropriate normative reference.

Conformity assessment and documentation

Use of EN 301 893 is voluntary. Manufacturers may use it as a harmonized route to demonstrate the Article 3(2) requirements within its scope, or use another technically justified conformity-assessment route.

The available RED conformity-assessment procedure depends on whether harmonized standards have been applied fully and cover all relevant essential requirements. Internal production control may be used where the conditions of RED Article 17 are met; otherwise an EU-type examination with conformity to type or full quality assurance is required. DFS or TPC functionality alone does not automatically require a Notified Body or testing by an accredited laboratory.

The manufacturer’s technical documentation must substantiate compliance with all applicable requirements. The EU Declaration of Conformity identifies the harmonized standards or other technical specifications actually used; EN 301 893 should not be listed if it was not part of the assessment.

Lifecycle relevance

• Define equipment roles, supported bands, power classes, antenna configurations and operating modes before planning the test programme.

• Assess changes to radio hardware, firmware, antennas, channel-access behavior, DFS or TPC for their effect on the documented conformity assessment.

• Monitor ETSI editions, Official Journal citations and national conditions for ongoing production and intended countries of use.
