Meaning
Formal regulatory authorization confirms that electromagnetic field strength radiated by a radio frequency device complies with legal human exposure boundaries. Achieving radiated exposure certification requires rigorous physical testing inside anechoic chambers or calibrated SAR measurement facilities. Regulatory authorities like the Federal Communications Commission or European notified bodies issue compliance grants based on certified laboratory test reports.
The certification covers intentional and unintentional radiated electromagnetic fields under specified operational power limits.
Compliance Testing
Electromagnetic field measurements evaluate total radiated power and spatial field distribution in proximity to representative human tissue models. Submitting a product for radiated exposure certification involves operating the transmitter at maximum output power across all supported frequency bands and modulation modes. Field probes record electric field strength to verify that local power density remains below statutory limits.
Regulatory Approval
Telecommunication authorities mandate compliance documentation before connected commercial products can be legally sold. Obtaining radiated exposure certification provides legal authorization to apply required compliance marks to product packaging and device rating labels.
Product Modification
Engineering changes to antenna gain, enclosure geometry, or maximum output power invalidate existing compliance approvals. Maintaining valid radiated exposure certification requires supplementary testing or permissive change filings whenever hardware modifications alter radiated power distribution.
