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.
ANATEL Act 16307
Meaning
Administrative resolutions issued by the National Telecommunications Agency in Brazil establish mandatory testing procedures and limit values for human exposure to radiofrequency fields. Under anatel act 16307, any wireless device operating close to the human body must undergo specific absorption rate evaluation prior to commercialisation. The rules define the scope of compliance for portable terminal stations, establishing the conditions where testing applies to mobile handsets and connected accessories.
Testing Threshold
Thresholds for measurement are defined by the operating frequency and the distance of the transmitter from the user. For devices covered under the Brazilian framework, specific absorption rate limits are set at two watts per kilogram averaged over ten grams of tissue for the head and trunk. Transmitters operating below certain low-power levels are exempt from laboratory testing under these provisions.
System Evaluation
Measurement techniques utilize standardized anthropomorphic liquid-filled phantoms and automated probe positioning systems to chart energy deposition. Automated test stations record peak electrical field intensity in the liquid during continuous radio frequency transmissions. Laboratory testing requires using calibration methods aligned with international standards to ensure repeatable data across various test runs.
Compliance Obligation
Conformity assessment leads to the issuance of a formal certificate of homologation required for legal distribution. Regional audits check that physical samples match the registered configuration. Non-compliance results in the suspension of sales.
