CE Compliance for Wireless and Telecom Equipment: RED Requirements Explained

Bringing a wireless or connected product to the European market requires more than simply applying a CE mark. CE compliance is a key requirement for placing telecom and wireless products on the market across the EU and EEA.

Unlike countries requiring separate national telecom type approvals, Europe follows a harmonized conformity assessment system. Once a product complies with applicable requirements, such as the Radio Equipment Directive (RED), it can generally be marketed across EU and EEA countries without separate national approvals.

However, CE marking is not a global certification. While some countries accept CE-based test reports or technical documents, manufacturers must still meet the specific regulatory requirements of each target market.

What Does the CE Mark Mean?

CE stands for Conformité Européenne, meaning European Conformity.

By affixing the CE mark, a manufacturer declares that the product complies with the applicable European legislation and accepts responsibility for ensuring continued compliance.

For wireless and telecommunications equipment, the primary legislation is the Radio Equipment Directive (RED) 2014/53/EU.

The RED establishes essential requirements relating to:

• Protection of health and safety

• Electromagnetic compatibility (EMC)

• Effective and efficient use of radio spectrum

• Avoidance of harmful interference

• Certain additional requirements for specific categories of radio equipment

Before placing radio equipment on the Union market, manufacturers must complete the appropriate conformity assessment procedure, prepare the required technical documentation, and issue an EU Declaration of Conformity (DoC).

CE Compliance Is a Process, Not Just a Mark

The CE mark is the visible outcome of a structured compliance process rather than a certificate issued by a regulatory authority.

For wireless products, manufacturers typically need to:

• Identify the applicable EU legislation

• Determine the relevant harmonized standards

• Perform the necessary testing and technical assessments

• Prepare and maintain technical documentation

• Issue the EU Declaration of Conformity

• Apply the CE marking before placing the product on the Union market

When relevant harmonized standards published in the Official Journal of the European Union (OJEU) are correctly applied, they provide a presumption of conformity with the essential requirements covered by those standards under the applicable EU legislation.

The CE framework applies across the European Union and EEA, including Poland and Italy etc.

Which Products Require CE Compliance?

CE marking applies to many categories of products placed on the European market.

For wireless and telecommunications equipment, this commonly includes:

• Wi-Fi devices

• Bluetooth products

• Cellular devices

• IoT equipment

• Smart home devices

• Wireless sensors

• Short-range radio equipment

• Connected consumer electronics

The exact conformity assessment requirements depend on the product's design, radio technology, operating frequency bands, intended use, and the applicable EU legislation.

Key Elements of CE Compliance for Wireless Products

Applicable Harmonized Standards: Manufacturers must identify and apply the relevant harmonized European standards. Using standards published in the Official Journal of the European Union (OJEU) provides a recognized pathway to demonstrate conformity with applicable requirements.

RF Testing: RF testing verifies that wireless devices meet radio performance and spectrum requirements, including parameters such as output power, frequency stability, bandwidth, emissions, and efficient spectrum use.

EMC Testing: EMC testing ensures the product does not create unacceptable electromagnetic interference and can operate reliably in environments with electromagnetic disturbances.

Safety and Health Assessment: Depending on the product, compliance may require assessments related to electrical safety, protection against electric shock, electromagnetic field exposure, and SAR evaluation where applicable.

Technical Documentation: Manufacturers must maintain technical documentation proving compliance. This typically includes product details, technical specifications, design information, risk assessments, applied standards, test reports, and other supporting evidence.

The Role of Testing Laboratories

Testing provides the technical evidence supporting a manufacturer's conformity assessment.

Depending on the product and conformity assessment procedure, testing may be carried out by:

• The manufacturer's own competent testing facilities

• Competent external testing laboratories

• A Notified Body, where required under the applicable conformity assessment procedure

It is important to note that testing laboratories do not issue CE marking. Test reports provide evidence supporting compliance, while the legal responsibility for conformity always remains with the manufacturer.

Do All Products Require a Notified Body?

No.

Many radio equipment products are assessed using the Internal Production Control conformity assessment procedure set out in Annex II of RED.

Notified Body involvement may be required when the manufacturer has not applied the relevant harmonized standards, has applied them only in part, or where harmonized standards do not exist for certain applicable essential requirements.

In such cases, the manufacturer may need to follow the conformity assessment procedure described in Annex III of RED.

Additional EU Legislation That May Apply

While the Radio Equipment Directive is the primary framework for wireless and telecommunications equipment, additional EU legislation may also apply depending on the product's characteristics and intended use.

Examples may include:

• RoHS Directive (2011/65/EU)

• Battery Regulation (EU) 2023/1542

• Ecodesign requirements

• Packaging and environmental obligations

• Other product-specific EU legislation

Manufacturers should therefore assess all applicable regulatory requirements before placing products on the Union market.

Why Early Compliance Planning Matters

A well-planned compliance strategy can help manufacturers reduce regulatory delays, avoid unnecessary testing, and minimize the risk of corrective actions after products enter the market.

Common compliance issues include:

• Testing against outdated harmonized standards

• Missing RF or EMC assessments

• Incomplete technical documentation

• Incorrect CE marking or product labeling

• Errors in the EU Declaration of Conformity

Addressing these issues early can streamline market access and improve regulatory confidence.
