The Radio Equipment Directive (2014/53/EU) replaced the older Radio and Telecommunication Terminal Equipment (R&TTE) Directive (1999/5/EC) on June 13, 2016, modernizing regulations for wireless devices across the EU.

The Radio Equipment Directive (2014/53/EU) has been applicable since 13 June 2016.

Manufacturers faced a transitional phase until June 12, 2017, during which they could comply with either the new RED or the legacy R&TTE rules. This update aimed to address emerging technologies like IoT devices, software-defined radios, and 5G equipment, ensuring safer and more interoperable products for consumers.

Why the RED Matters for Manufacturers
The RED establishes stricter requirements for radio equipment, emphasizing electromagnetic compatibility (EMC), efficient spectrum use, and user safety. Key changes include mandatory testing for software-driven devices and enhanced traceability through technical documentation. For example, Bluetooth speakers or Wi-Fi routers must now undergo EMC testing to minimize interference with other devices. Companies must also label products with the CE mark and include the importer’s contact details, a shift from the R&TTE’s simpler compliance framework.

Transition Phase Insights
During the 2016–2017 transitional period, manufacturers could choose between the RED or R&TTE frameworks. However, after June 2017, only RED-compliant devices could enter the EU market. Harmonized standards like EN 300 328 (for Wi-Fi) and EN 301 893 (5 GHz band) became critical for demonstrating compliance. Proactive businesses used this window to conduct preliminary design reviews and partner with accredited labs, avoiding costly redesigns post-deadline.

Transitional Phase (June 2016–June 2017)

From 13 June 2016 to 12 June 2017, tools could meet either RED or R&TTE requirements. This interval let businesses:

Conduct preliminary design reviews under both frameworks.
Partner with notified bodies and accredited labs to retest existing products.
Avoid costly retrofits by phasing in dual-compliant designs.

Key Changes Under RED

Conformity Assessment: Mandatory testing of software-driven and multi-radio equipment per ETSI EG 203 367 guidance.
CE Marking Rules: CE can only be affixed after full conformity assessment; voluntary marks are not sufficient.
New Harmonized Standards:
- EN 300 328 for 2.4 GHz wideband data (Wi-Fi/Bluetooth)
- EN 301 893 for 5 GHz high-rate WLAN operation

Steps to Ensure RED Compliance

Scope Assessment: Determine if your product falls under RED (e.g., cellular devices, RFID systems, routers).
Risk Analysis & Testing: Engage ISO 17025-accredited labs to validate EMC, safety and spectrum-use requirements.
Quality Systems: Adopt ISO 9001 practices to manage design changes and supplier coordination.
Market Monitoring: Watch for harmonized-standard updates and RED amendments (e.g., cybersecurity rules under Article 3.3 in future RED 3.3).
Testing & Documentation: Validate EMC, safety, and spectrum efficiency with accredited laboratories.
CE Marking: Affix labels and prepare Declaration of Conformity (DoC).

Non-compliance risks market withdrawals or fines. For complex products like industrial IoT sensors, consider radio equipment testing early in development to address interoperability issues.

Conclusion
The RED ensures radio devices meet evolving EU safety and performance standards. By aligning with harmonized norms and leveraging accredited testing partners, manufacturers can streamline compliance and maintain market access. By using the 2016–2017 transition wisely, manufacturers not only met EU rules but also future-proofed devices for today’s connected ecosystem.
