Executing FCC Section 2933 Change in Identification Filings
Section 2933 filings transfer FCC equipment authorization to a new grantee code without retesting, provided hardware and circuitry remain unchanged.
Compliance Test Data Reuse
Meaning
Regulatory efficiency procedures allow an applicant to apply existing electromagnetic compatibility measurements from a previously certified wireless module to a new host device. When integrating a pre-approved transmitter, compliance test data reuse eliminates the need to perform full radiated emissions testing on the finished assembly. This process is limited to configurations where the antenna gains and trace layouts match the original module grant.
Integration Limit
Host board designers must adhere strictly to the reference layout guidelines provided by the module manufacturer to claim compliance test data reuse for their product. Any deviation in trace geometry or shielding requires fresh transmitter testing to satisfy FCC and RED mandates.
Documentation Package
Filing submissions to the telecommunications certification body must contain a detailed justification document explaining why the original data remains representative of the new host device. This packet includes comparative block diagrams and antenna specification sheets alongside the original grant files to support compliance test data reuse without full re-evaluation. Hardware engineering teams draft this justification during the initial design phase to streamline the final certification route.
Spot Check
Validation teams run simplified radiated emissions measurements on a sample of production units to confirm that no new spurious harmonics have emerged. This process of selective validation during compliance test data reuse ensures that the integrated shielding and power supply routing do not compromise the electromagnetic performance of the completed assembly.
