Determining Federal Permissive Change Thresholds for Transceiver Software Updates
Software updates altering RF output power, occupied bandwidth, duty cycle, or band limits exceed Class I limits and demand Class II or Class III filings.
Grant Attestation
Meaning
Formal declaration submitted by a grantee confirming that a device complies with specific technical or administrative requirements. The grant attestation provides a legal assurance that the software security or operational limits of a wireless module prevent unauthorized changes by third parties.
Compliance Warranty
Signatories verify that the hardware under review is identical to the units used in the laboratory for testing. A grant attestation acts as a promise that no undocumented hardware revisions occurred between the testing phase and the start of mass production.
Security Commitment
Software locks are described in this document to show how the manufacturer prevents the installation of third-party firmware. By signing the grant attestation, the applicant accepts responsibility for the integrity of the radio parameters throughout the life of the product.
Liability Framework
Legal consequences arise if a device is found to be operating outside its granted parameters due to a failure in the security architecture. The grant attestation acts as the primary record for enforcement agencies when investigating reports of spectrum interference. Regulatory authorities rely on this statement to hold the manufacturer accountable for any deviations from the original test report that appear in retail units.
This legal framework ensures that the security of the radio spectrum is maintained through personal and corporate accountability.
