Meaning
European harmonized standards for short-range devices specify the technical characteristics and test methods for radio equipment operating in the frequency range of 40 GHz to 246 GHz. Certification against etsi en 305 550 allows manufacturers to demonstrate compliance with the requirements of the Radio Equipment Directive. It establishes limits for transmitter power and unwanted emissions to prevent interference with other services.
This standard applies to generic sensors and industrial automation.
Spectrum Constraint
Maximum allowable radiated power levels are defined to ensure that high-frequency modules do not saturate nearby receivers. Compliance with etsi en 305 550 involves measuring the equivalent isotropically radiated power across the designated frequency band.
Technical Requirement
Frequency stability and occupied bandwidth tests confirm that the device remains within its allocated spectrum under varying voltage and temperature conditions. The provisions of etsi en 305 550 mandate that the signal does not wander into restricted bands used by satellite or radio astronomy services.
Compliance Path
Manufacturers must provide a technical file including test reports from an accredited laboratory to claim conformity. The use of etsi en 305 550 provides a presumption of conformity which simplifies the process of placing a product on the European market.
