Meaning
Directive 2014/53/EU establishes statutory requirements for radio equipment placed on the European Single Market. Manufacturers perform CE RED compliant testing to demonstrate receiver resistance and efficient spectrum usage before commercial distribution. Harmonized standards define specific radio frequency test procedures for cellular modules and short range wireless devices.
Regulatory Framework
Radio equipment directives require formal evaluation of electromagnetic compatibility and radio spectrum efficiency. Wireless products must undergo transmitter spurious emission scans and adaptive protocol checks in accredited test laboratories. Standard EN 300 328 governs wideband transmission systems operating in the two point four gigahertz band, enforcing power density boundaries and receiver blocking thresholds.
Non-compliant hardware configurations cannot receive CE marking or enter commercial supply chains within participating European states.
Assessment Sequence
Assessment plans sequence radiated power measurements, spurious emissions sweeps and receiver selectivity evaluations. Vector network analyzers and calibrated antennas capture radiated power levels across fundamental and harmonic bands.
Pass Criterion
Measured emission spectra must remain strictly below harmonized reference masks across all operating temperatures and supply voltages. Test reports generated during compliance testing form part of the technical construction file required for the EU declaration of conformity. Receiver sensitivity degradation under adjacent channel interference must not exceed standard limits during active data link testing.
Systematic compliance logging proves that integrated wireless modules maintain radio performance limits in final product enclosures.
