Managing Multi-Market Radio Frequency Exposure Filings for Handheld Transceivers
Handheld exposure filings demand unified 1g and 10g spatial SAR test plans, tight proximity sensor power backoff logic, and deterministic firmware controls.
EU RED EN 50566
Meaning
Harmonised standards under the Radio Equipment Directive of the European Union define the evaluation methods for wireless devices used close to the human ear or body. Under eu red en 50566, products must be evaluated for specific absorption rate compliance if they are held or worn within twenty centimetres of the user. This standard ensures that mobile devices sold in Europe do not exceed safe exposure limits.
Harmonised Requirement
The standard applies to devices like smartphones, tablets, and laptops that operate in frequency bands from thirty megahertz to six gigahertz. It specifies the exposure limits for the head, limbs, and torso. Testing laboratories use these parameters to generate compliance reports for the European market.
Testing Framework
Measurements use liquid-filled head and body phantoms to measure the electric fields generated by the device. The equipment is configured to transmit at maximum rated power for each supported band. Measurements must be taken with the device placed in realistic operating positions.
Market Entry
Compliance is a mandatory step before the CE mark can be applied to the product. Manufacturers must include the compliance declaration in the technical file. Failure to meet these requirements prevents legal sales within the European Economic Area.
