Radio Equipment Directive Host Integration Testing Procedures and Technical File Assembly
CE module approvals do not cover host integration; host manufacturers must execute physical delta testing and compile a full RED Technical File.
Article 3.2 Spectrum Efficiency
Meaning
Essential requirements for the effective use of radio spectrum dictate that wireless devices must use frequencies efficiently to avoid harmful interference. Meeting the demands of article 3.2 spectrum efficiency ensures that the transmitter uses only its assigned channel bandwidth. Receivers must also demonstrate resilience against adjacent channel signals during evaluation.
Channel Performance
Transmitter measurements focus on mask limits and out-of-band emissions to secure channel purity. The article 3.2 spectrum efficiency testing verifies that spurious emissions do not disrupt neighboring services. Engineers use vector signal analyzers to capture these spectral plots during the formal certification scan.
Radiated Performance
Antenna design affects the spatial distribution of the transmitted power and the receiver sensitivity. Standard tests require the integrated product to maintain stable transmitter power and receiver blocking thresholds under temperature variations. The output of these assessments determines if the product receives the necessary certification for the European market.
Coexistence Liability
Integration of a pre-certified radio module into a host enclosure can alter the radiation pattern and degrade the receiver performance. Developers must conduct a full risk assessment and delta-testing to confirm that the host design does not violate the article 3.2 spectrum efficiency requirements. If the enclosure introduces shielding that alters the antenna match, a complete re-measurement of the radiated parameters is required.
This technical file acts as the primary proof of regulatory compliance before the product is placed on the market.
