Meaning
A regulatory process requires a previously approved wireless device to undergo additional testing to maintain its compliance status after undergoing hardware or software modifications. This radio frequency recertification ensures that any changes to the transmitter and antenna do not exceed the permitted emission limits defined by government bodies. It is essential for maintaining the device’s legal status to transmit on designated radio bands.
Without this active verification, a modified device cannot be sold legally, protecting the wireless spectrum from unauthorized interference.
Compliance Testing
Accredited laboratories measure the device’s electromagnetic emissions across various frequencies in an anechoic chamber. During the radio frequency recertification, technicians verify that spurious emissions and specific absorption rates remain within safe, legal boundaries. These results are compiled into a formal test report for submission.
Technical Trigger
Minor design adjustments, such as replacing an obsolete radio chip or modifying the antenna trace, necessitate a re-evaluation of the device. The technical trigger dictates whether a full retest or a simplified permissive change filing is required by the regulatory agency. This determination depends on how the modifications affect transmitter performance.
Market Access
Approved certificates allow the manufacturer to continue selling and distributing the wireless product in various jurisdictions. The market access is suspended if the device fails to secure the updated approvals within the designated timeframe. This ongoing compliance prevents costly recalls and shipping halts.
