RED FAQ Receivers and transmitters

Directive 2014/53/EU covers electrical or electronic products that intentionally emit or receive radio waves for radio communication or radiodetermination, including products that need an accessory such as an antenna to do so.

This FAQ explains the scope test for receiver-only products, transmitters, products completed by antennas or software, and common cases that fall outside RED because the radio function is absent, excluded, or used for another purpose.

Overview

Receivers and transmitters are in RED scope when the product intentionally emits and/or receives radio waves for radio communication or radiodetermination. The same test can cover receiver-only equipment, transmitter-only equipment, transceivers, and products that must be completed with an accessory such as an antenna before they can perform the radio function.

Question 1

Which receivers and transmitters are covered by the Radio Equipment Directive?

A product is radio equipment under Directive 2014/53/EU if it is an electrical or electronic product that intentionally emits and/or receives radio waves for radio communication or radiodetermination. The definition also covers an electrical or electronic product that must be completed with an accessory, such as an antenna, so it can intentionally emit or receive radio waves for those purposes.

That means the RED scope question is not limited to two-way radios. A receiver-only product can be in scope if its intended function is radio communication or radiodetermination, and a transmitter or transceiver is in scope when it intentionally uses radio waves for those purposes. The Commission RED Guide identifies pure television and sound broadcasting receivers as products that remained within RED scope when RED replaced the older R&TTE framework.

  • Include transmitter-only, receiver-only, and transmit/receive equipment when the intended radio function is communication or radiodetermination.
  • Include products that need an accessory, such as an antenna, or software before they can intentionally emit or receive radio waves.
  • Do not treat every electromagnetic product as RED equipment; the radio waves must be used for radio communication or radiodetermination.
  • After the scope answer is yes, map the product to Article 3 requirements, applicable harmonised standards or other technical specifications, conformity assessment, user information, and technical documentation.

Article 2 defines radio equipment by intentional emission or reception of radio waves for radio communication or radiodetermination, including products completed with an accessory such as an antenna.

Question 2

What is outside RED receiver and transmitter scope?

A product is not brought into RED scope merely because it involves electromagnetic phenomena. The Commission RED Guide says products that use electromagnetic waves exclusively for purposes other than radio communication or radiodetermination are not covered by RED, and gives pure wireless power transfer without communication or radiodetermination as an example.

RED also has explicit exclusions. Annex I excludes certain radio amateur equipment that is not made available on the market, marine equipment within the listed marine-equipment regime, airborne products, parts and appliances within the listed aviation regime, and custom-built evaluation kits destined for professionals for use solely at research and development facilities.

  • Exclude electromagnetic products only where the intended use is not radio communication or radiodetermination.
  • Check Annex I before relying on an exclusion for amateur radio, marine, airborne, or custom-built professional R&D evaluation equipment.
  • For mixed products, separate the radio equipment assessment from non-radio functions instead of using one broad product label.

Question 3

Evidence to keep for a receiver or transmitter scope decision

The technical file should show why the product was treated as RED radio equipment or why it was excluded. Keep the scope decision close to the product description, intended use, radio technology, frequency information, accessory and software dependencies, and any exclusion analysis.

Once the product is in scope, Article 3 evidence should be organized around the applicable essential requirements. Annex V technical documentation includes a general description of the radio equipment, relevant software or firmware versions, user information and installation instructions, design and circuit information, standards or other technical specifications used, EU declaration, notified-body certificate where applicable, design calculations and examinations, test reports, and the Article 10(2) and 10(10) explanations where relevant.

  • Record whether the product emits, receives, or both, and whether the function is radio communication, radiodetermination, or neither.
  • Identify the radio waves involved as electromagnetic waves below 3 000 GHz propagated in space without artificial guide.
  • List antennas, software, firmware, modules, accessories, or configurations needed for the intended radio function.
  • Keep the Article 3 matrix, standards list, test reports, EU declaration of conformity, and notified-body evidence where the selected conformity route requires it.
  • Revisit the scope record when the radio function, antenna, firmware, intended use, market configuration, harmonised standard, or exclusion basis changes.

Commission guidance that harmonised standards can provide presumption of conformity where their references are published in the OJEU, and that other means require technical justification.

Recommended next step

Review a receiver or transmitter scope call

Check whether the product intentionally emits or receives radio waves for radio communication or radiodetermination, then connect the RED scope answer to Article 3 evidence, standards, conformity assessment, and technical documentation.

Question 4

Common mistakes when classifying receivers and transmitters

The main mistake is asking whether the product is a familiar radio category instead of applying the Article 2 definition. RED scope turns on the intentional emission or reception of radio waves for radio communication or radiodetermination, not on marketing labels such as smart device, sensor, accessory, module, or consumer electronics.

A second mistake is stopping after the scope answer. If the receiver or transmitter is in scope, the compliance file still needs the Article 3 requirements, applicable standards or other specifications, conformity assessment route, user information, EU declaration, CE marking, and technical documentation that match the exact radio equipment type.

  • Do not exclude receiver-only equipment just because it does not transmit.
  • Do not include pure wireless power transfer or other electromagnetic uses unless the product also uses radio waves for communication or radiodetermination.
  • Do not rely on a module or component claim without checking the final product configuration and intended use.
  • Do not cite a harmonised standard as full RED coverage unless the standard, OJEU citation, product configuration, and covered Article 3 requirement all line up.
